Description

Technical Field

[0001] This invention relates to the field of medicinal paste preparation technology, and in particular to a method for preparing medicinal paste using the eight-step process. Background Technology

[0002] The eight-step process of making medicinal pastes, as an important carrier of intangible cultural heritage of traditional Chinese medicine, has a profound historical accumulation and cultural inheritance. Its origin can be traced back to the late Qing Dynasty. The first generation of founders laid the foundation when they studied traditional Chinese medicine theory and paste making techniques at En Hui Chang. The second generation of inheritors systematically summarized and named it after establishing Lishengtang. After five generations of inheritors adhered to and developed it, a clear family inheritance system was formed. This process fully preserves the core essence of ancient medicinal paste making. Its eight major steps are consistent with the medicinal paste making standards recorded in the Song Dynasty's "Taiping Huimin Heji Jufang". It not only carries the TCM concept of diagnosis and treatment based on the time and individual, but also continues the living inheritance characteristic of traditional craftsmanship through oral transmission from master to apprentice. It is a typical representative of the essence of traditional craftsmanship in TCM culture.

[0003] However, the traditional eight-step process of making medicinal pastes has gradually revealed its inadequacy in adapting to modern production over a long period of practice. The core problems lie in the low degree of standardization of the process and poor quality stability. Traditional processes rely heavily on the experience of inheritors, from judging the quality of medicinal materials by sight and touch during selection, to controlling temperature and time by observing the color of the fire and feeling during processing, and then judging the state of the finished product by observing the color and distinguishing the strands during the final product collection. All of these processes lack quantifiable parameters and controllable standards. This results in significant differences in key indicators such as the content of effective ingredients, the removal rate of impurities, and the taste and texture of medicinal pastes made by different batches and by different inheritors. Some batches even suffer from loss of effective ingredients or excessive impurities due to improper processing, making it difficult to meet the basic requirements of modern TCM production for traceability, reproducibility, and controllability.

[0004] Meanwhile, there is a gap between traditional techniques and the physical characteristics and usage needs of modern people. On the one hand, traditional herbal paste formulas are mostly designed based on the constitution of ancient people, while modern people, due to factors such as sedentary lifestyles, irregular diets, and high stress, generally exhibit the characteristics of qi deficiency and insufficient internal heat. Traditional formulas tend to have a high proportion of heat-clearing herbs and a low proportion of qi-tonifying herbs, which can easily lead to discomfort for people with weak spleen and stomach. On the other hand, herbal pastes made using traditional techniques have a short shelf life and are prone to problems such as rough texture and difficulty in dissolving when taken, which falls short of modern consumers' needs for long-term storage, convenient consumption, and a superior experience of health products, thus limiting the promotion and popularization of traditional herbal pastes in the contemporary market. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention discloses a method for preparing traditional Chinese medicine pastes using an eight-step process.

[0006] This invention discloses a method for preparing traditional Chinese medicine pastes using eight complex processes, characterized by comprising the following steps performed sequentially:

[0007] Step (1) Material selection: Following the principle of authentic medicinal materials, select medicinal materials from specific production areas, harvest them during their best harvest period, and screen them based on appearance, smell, touch, taste, water immersion and fire test;

[0008] Step (2) Processing: According to the properties of the medicinal materials, at least one of the following methods is used: stir-frying, roasting, simmering, calcining, steaming, boiling, combined with at least one of the following auxiliary materials: wine, ginger, salt, vinegar or black bean juice. The processing process is carried out using intelligent temperature and humidity control.

[0009] Step (3) Cleaning: Use graded cleaning method, use mineral groundwater with a water temperature of 15-20℃ to clean the medicinal materials, and let them drain naturally after cleaning;

[0010] Step (4) Soaking: Place the cleaned medicinal materials in an environment of 0-10℃ and add auxiliary solvent to soak for 8-16 hours;

[0011] Step (5) Decoction: Decoction is carried out 2-4 times at 100-120℃, each time for 30-90 minutes;

[0012] Step (6) Concentration: Concentrate the decoction at 60-90℃ for 2-6 hours until the relative density at 25℃ is 1.1-1.3;

[0013] Step (7) Filtration: Multi-stage filtration is carried out sequentially using gauze, filter paper and ultrafiltration membrane. The pore size of the ultrafiltration membrane is 0.1-1μm.

[0014] Step (8) Finishing the paste: Add the excipients at 50-70℃ and finish the paste over low heat until the paste forms droplets that form threads.

[0015] Furthermore, in step (1), the specific production areas include Shandong, Sichuan, Yunnan, and Zhejiang; the optimal harvesting periods are spring, summer, autumn, and winter, respectively; and the effective component content of the screened medicinal materials is not less than 85% of the industry standard.

[0016] Furthermore, in step (2), the processing temperature is 50-120℃ and the time is 30 minutes to 6 hours; the weight ratio of medicinal materials to excipients is 10:1 to 10:3.

[0017] Further, in step (3), the graded cleaning includes: ultrasonic cleaning of hard medicinal materials for 5-10 minutes, rinsing of loose medicinal materials with running water for 3-5 minutes, and soaking and cleaning of medium-textured medicinal materials for 8-12 minutes; the draining time is 2-4 hours.

[0018] Further, in step (4), the auxiliary solvent is at least one of pure water, rice wine or rice wine; the weight-volume ratio of medicinal material to solvent is 1g:3-8mL; during the soaking process, it is stirred once every 3-4 hours at 30-50r / min.

[0019] Furthermore, in step (5), after each decoction, let it stand for 20-40 minutes before the next decoction; add 5-10L of water for every 1kg of medicinal materials.

[0020] Furthermore, in step (6), the concentration method is atmospheric pressure concentration or vacuum concentration; the vacuum degree during vacuum concentration is 0.05-0.09 MPa.

[0021] Further, in step (7), the drug solution is allowed to stand for 1-3 hours before filtration; optionally, centrifugation is performed under the conditions of 3000-5000 r / min for 10-20 minutes.

[0022] Further, in step (8), the excipient is at least one of honey, rock sugar, donkey-hide gelatin, and deer antler gelatin; the weight ratio of the medicinal liquid to the excipient is 5:1 to 5:3; the temperature for finishing the paste is adjusted according to the season: 55-60℃ in spring, 50-55℃ in summer, 60-65℃ in autumn, and 65-70℃ in winter; the relative density of the paste at 25℃ is 1.3-1.5.

[0023] Furthermore, in step (8), probiotics are added at a rate of 0.01%-0.1% of the total weight of the paste. The probiotics are Bifidobacterium or Lactobacillus. And / or, the amount of Qi-tonifying herbs is increased by 10%-20% and the amount of heat-clearing herbs is reduced by 5%-15% in the formula. The shelf life of the paste is not less than 18 months and the loss rate of effective ingredients during storage does not exceed 10%.

[0024] The beneficial effects of this invention are:

[0025] This invention addresses the pain points of inconsistent quality and unstable efficacy in traditional herbal paste production through a standardized end-to-end design. The material selection process focuses on authentic producing areas and optimal harvesting periods, coupled with standardized component testing to ensure consistent efficacy of raw materials. Precise parameters replace experience-based operations in processing, cleaning, and decoction, making each step traceable and reproducible. Simultaneously, multi-stage filtration and low-temperature concentration maximize the retention of active ingredients. Compared to traditional processes, the retention rate of active ingredients is increased by 15%-20%, and the utilization rate of medicinal materials is improved by 25%-30%. The final herbal paste exhibits a high degree of consistency in efficacy concentration and purity, overcoming the industry challenge of inconsistent efficacy with the same formula.

[0026] This invention is deeply adapted to the physical characteristics and usage needs of modern people, breaking through the limitations of traditional herbal pastes. Addressing the characteristics of modern people such as intestinal flora imbalance and the high incidence of Qi deficiency, probiotics are added during the paste-making process to improve ingredient absorption, and the dosage of Qi-tonifying herbs is adjusted to enhance compatibility. This allows herbal pastes to shift from a general-purpose to a precise approach, expanding the applicable population by more than 30%. The 18-month shelf life and stable storage effect solve the problems of traditional herbal pastes being prone to short-term spoilage and requiring frequent preparation. Combined with a delicate taste and convenient consumption method, it better meets the health needs of a fast-paced lifestyle, effectively improving the inconvenience and narrow target audience of traditional herbal pastes.

[0027] This invention organically integrates traditional Chinese medicine techniques with modern technology, providing a feasible path for the living inheritance and industrial development of intangible cultural heritage crafts. The process design adheres to the core concepts of traditional Chinese medicine, such as the differentiation of syndromes and treatment using authentic medicinal materials, and retains the traditional essence of the eight complex processes. At the same time, it utilizes modern technologies such as intelligent temperature control, ultrafiltration membrane filtration, and component detection to free traditional crafts from the constraints of reliance on experience and difficulty in scaling up. This not only revitalizes ancient herbal pastes in the modern era but also provides a model for the modernization of traditional Chinese medicine intangible cultural heritage, promoting the standardization, normalization, and industrialization of traditional crafts.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below.

[0033] This invention discloses a method for preparing traditional Chinese medicine pastes using eight complex processes, which includes the following steps performed sequentially:

[0034] Step (1) Material selection: Following the principle of authentic medicinal materials, select medicinal materials from specific production areas, harvest them during their best harvest period, and screen them based on appearance, smell, touch, taste, water immersion and fire test;

[0035] Step (2) Processing: According to the properties of the medicinal materials, at least one of the following methods is used: stir-frying, roasting, simmering, calcining, steaming, boiling, combined with at least one of the following auxiliary materials: wine, ginger, salt, vinegar or black bean juice. The processing process is carried out using intelligent temperature and humidity control.

[0036] Step (3) Cleaning: Use graded cleaning method, use mineral groundwater with a water temperature of 15-20℃ to clean the medicinal materials, and let them drain naturally after cleaning;

[0037] Step (4) Soaking: Place the cleaned medicinal materials in an environment of 0-10℃ and add auxiliary solvent to soak for 8-16 hours;

[0038] Step (5) Decoction: Decoction is carried out 2-4 times at 100-120℃, each time for 30-90 minutes;

[0039] Step (6) Concentration: Concentrate the decoction at 60-90℃ for 2-6 hours until the relative density at 25℃ is 1.1-1.3;

[0040] Step (7) Filtration: Multi-stage filtration is carried out sequentially using gauze, filter paper and ultrafiltration membrane. The pore size of the ultrafiltration membrane is 0.1-1μm.

[0041] Step (8) Finishing the paste: Add the excipients at 50-70℃ and finish the paste over low heat until the paste forms droplets that form threads.

[0042] The eight-step process of making medicinal pastes involves eight interconnected core steps, forming a complete system for paste production. The material selection process strictly adheres to the principle of authentic medicinal herbs, selecting pure varieties from specific producing areas and harvesting each herb according to its traditional optimal harvest time. High-quality herbs are then precisely selected through a rigorous screening process involving observation, smelling, touching, tasting, soaking, and roasting. The processing follows the traditional Chinese medicine theories of wine-based processing for elevation, ginger-based processing for dispersion, salt-based processing for downward movement, and vinegar-based processing for liver function. For different herbs, at least one technique from stir-frying, roasting, simmering, calcining, steaming, and boiling is used, combined with modern technology to create personalized solutions, and parameters are adjusted according to seasonal adaptation. The cleaning process employs a graded cleaning method, using mineral-rich groundwater and treating the herbs at a temperature of 15-20℃. Naturally drain to avoid loss of ingredients; during the soaking stage, place the cleaned herbs in a clean container, add an auxiliary solvent that can cover the herbs, and soak continuously at low temperature for 8-16 hours; then, use high-intensity heat to repeatedly decoct the herbs 2-4 times to promote the dissolution of active ingredients; next, continue to heat over low heat to slowly concentrate the decoction at low temperature; then, through multi-stage filtration and sedimentation, remove impurities and sediment from the decoction at least three times; finally, precisely control the heat and add excipients, and slowly reduce the paste at 50-70℃ until the paste reaches the standard of dripping into beads and picking into threads, ultimately forming a paste that is as black as lacquer, as shiny as a mirror, and melts in the mouth.

[0043] The screening in step (1) based on appearance, odor, touch, taste, water immersion, and fire tests is a comprehensive preliminary screening conducted in this field, combining traditional identification experience with modern observable indicators. Examples of its specific operation and judgment criteria are as follows:

[0044] Appearance: Observe whether the shape, size, color, and surface texture of the medicinal material conform to the inherent characteristics of the variety, and whether there is insect infestation, mold, dyeing, or adulteration.

[0045] Odor: Smell the medicinal materials to see if they have their own unique, rich aroma or medicinal smell, and whether there are any abnormal odors such as sourness or rottenness.

[0046] Touch test: Weigh the medicinal materials by hand to feel their texture, whether it is firm, soft or brittle, and whether the surface is smooth or rough, in order to judge the degree of dryness and quality.

[0047] Taste: Take a very small amount of the medicinal material and chew it to taste its inherent taste characteristics (such as sweet, bitter, pungent, etc.), and perceive whether there is a gritty feeling, an off-flavor, or an abnormal irritation.

[0048] Water immersion: Briefly immerse the medicinal material sample in clean water and observe whether the color change of the aqueous solution is abnormal (such as excessively rapid or dark coloring may indicate staining), and whether there are a large number of impurities suspended or precipitated.

[0049] Burning test: Take a small sample of the medicinal material and burn it over a flame. Observe the ease of burning, the color of the smoke (e.g., genuine frankincense produces black smoke), the shape and color of the ash left after it is extinguished, and smell the odor produced during burning. These can be used as an auxiliary reference to identify authenticity and whether the product is contaminated.

[0050] It should be noted that the above six-step screening method is a rapid and comprehensive on-site experience-based identification method. Its purpose is to initially eliminate medicinal materials from a large batch of raw materials that are obviously inconsistent in appearance, deteriorated, or suspected of being counterfeit. This screening is an important preliminary step for subsequent modern instrumental testing (such as content determination), and the combination of the two ensures the basic quality of the medicinal materials used.

[0051] This process ensures consistent quality of medicinal pastes throughout the entire process, while significantly improving raw material utilization efficiency. The combination of authentic ingredient selection and a six-step screening process eliminates inferior and mixed medicinal materials from the source, preventing raw material issues from affecting subsequent quality. Modern technology is incorporated into the processing, allowing precise control of key parameters such as temperature and time, replacing the traditional experience-based approach and ensuring stable detoxification and enhanced efficacy for each batch of medicinal materials. The slow soaking and prolonged soaking at low temperatures fully softens the medicinal cell and clears the channels for the dissolution of effective components. Combined with 2-4 rounds of repeated high-heat decoction, the core active ingredients such as alkaloids, polysaccharides, and saponins are fully extracted, reducing waste. Multi-stage, three-stage filtration and sedimentation removes impurities from the liquid, preventing them from interfering with the purity and taste of the medicinal paste, ensuring consistency in quality and efficacy across different batches. This addresses the pain points of inconsistent quality and low raw material utilization in traditional medicinal paste production.

[0052] The process design fully preserves the medicinal efficacy while adapting to the needs of modern consumers, achieving an organic integration of tradition and modernity. The slow, low-temperature simmering and concentration process avoids high temperatures that could damage the heat-sensitive active ingredients in the herbs, maximizing the preservation of their original medicinal properties. The temperature control at 50-70℃ during the final paste-making stage, along with the standards of dripping into beads and forming threads, ensures the paste forms a stable colloidal structure, facilitating storage and consumption. Furthermore, the optimized taste through the addition of excipients addresses the issues of traditional pastes being rough and difficult to swallow. The seasonal processing principle and the timely selection of authentic ingredients make the paste more suitable for the physical characteristics of people in different seasons. The finished paste combines medicinal efficacy with nutritional value, effectively preventing and treating diseases, promoting health, and is safe with no significant side effects, meeting the modern consumer's demand for convenient, safe, and highly effective health products.

[0053] As one implementation method, the specific production areas mentioned in step (1) include traditional production areas such as Shandong, Sichuan, Yunnan, and Zhejiang. The optimal medicinal material harvesting time is selected according to the variety: spring (March-May), summer (June-August), autumn (September-November), or winter (December-February). The screened medicinal materials must meet the requirement that the content of effective ingredients is not less than 85% of the industry standard.

[0054] The process is implemented through a three-step approach: targeted origin selection, timed harvesting control, and component testing and verification. In terms of origin selection, the focus is on traditional producing areas such as Shandong, Sichuan, Yunnan, and Zhejiang. Core producing areas are matched according to the growth habits of different medicinal herbs. For example, donkey-hide gelatin is sourced from Dong'e in Shandong, Sichuan's chuanxiong from Dujiangyan, Yunnan's sanqi from Wenshan, and Zhejiang fritillary from Yinzhou, ensuring that the herbs accumulate high-quality components in suitable soil fertility, climate, and water quality. Harvesting time is precisely divided according to the growth cycle and component accumulation patterns of the medicinal herbs. Spring-germinating herbs such as astragalus and angelica are harvested from March to May, while summer herbs are harvested from June to May. In August, honeysuckle, coptis, and other summer-ripening medicinal herbs are harvested; in autumn, from September to November, wolfberry, ophiopogon japonicus, and other autumn-fruiting medicinal herbs are harvested; and in winter, from December to February, ginseng, aconite, and other overwintering dormant medicinal herbs are harvested to avoid the loss of effective components due to harvesting too early or too late. After screening, modern detection technologies such as high performance liquid chromatography and thin-layer chromatography are used to quantitatively analyze the core effective components in the medicinal herbs, such as saponins, polysaccharides, and alkaloids, to ensure that the test results are not lower than 85% of the industry standard, thus forming a complete chain control from the place of origin to the components.

[0055] Traditional producing areas, through long-term practice, have proven that their unique natural environments can promote the formation of better effective component compositions and proportions in medicinal materials. For example, the groundwater in Dong'e, Shandong, is rich in minerals, which can help collagen in donkey-hide gelatin form a more stable molecular structure. Time-based harvesting precisely matches the peak efficacy period of medicinal materials, avoiding a decrease in the content of effective components due to improper harvesting. For example, the berberine content of Coptis chinensis harvested in summer is 15%-20% higher than that of Coptis chinensis harvested in autumn. The standard of no less than 85% effective components is replaced by quantitative indicators to replace traditional experience-based judgment, eliminating the mixing of inferior and low-component medicinal materials, ensuring that the efficacy of each batch of raw materials is consistent, and solving the problem of raw material quality fluctuations caused by vague origins and arbitrary harvesting in traditional material selection.

[0056] Meanwhile, this implementation method also provides a high-quality foundation for subsequent process steps, improving overall efficiency and the value of the finished product. High-quality, authentic raw materials have lower impurity content, reducing the operational intensity and time cost of deep cleaning and preventing excessive impurities from affecting the integrity of the cleaned medicinal materials. Raw materials meeting the standards for effective components do not require adjustments to processing parameters due to insufficient components during subsequent processing, enabling more precise achievement of the goal of reducing toxicity and increasing efficacy. Furthermore, ample reserves of effective components allow for more efficient extraction of core components during high-heat decoction and low-heat simmering processes, reducing the loss of effective components. Ultimately, this significantly improves the efficacy concentration and stability of the finished medicinal paste, meeting modern consumers' demand for controllable efficacy in health products while inheriting the traditional concept of using authentic Chinese medicinal materials as a base, achieving an organic integration of traditional techniques and modern standards.

[0057] As one implementation method, the modern technology in step (2) includes intelligent temperature control equipment, infrared temperature measuring device and humidity monitoring system. The processing temperature is controlled at 50-120℃, the processing time is 30 minutes to 6 hours, and the weight ratio of medicinal materials to processing excipients is 10:1-10:3. The excipients are selected from at least one of wine, ginger, salt, vinegar and black bean juice.

[0058] A standardized processing flow is constructed through equipment collaboration, precise matching of auxiliary materials, and dynamic parameter adjustment. First, a processing system is established, with intelligent temperature control equipment as the core and infrared temperature measurement devices and humidity monitoring systems as auxiliary components. The intelligent temperature control equipment is used to set and maintain the overall temperature, the infrared temperature measurement devices monitor the internal and surface temperatures of the medicinal materials in real time, and the humidity monitoring system adjusts the humidity of the processing environment synchronously. Then, appropriate excipients are selected according to the medicinal properties of the medicinal materials. For example, rice wine is used for wine processing, ginger juice boiled with fresh ginger is used for ginger processing, refined salt solution is used for salt processing, aged vinegar is used for vinegar processing, and concentrated juice from fermented black beans is used for black bean juice processing. The medicinal materials and excipients are mixed in a weight ratio of 10:1 to 10:3. For example, rice wine is added at a ratio of 10:2 when processing angelica, and salt solution is added at a ratio of 10:1 when processing eucommia. Finally, the processing parameters are adjusted according to the texture of the medicinal materials. For light and thin medicinal materials, the temperature is controlled at 50-80℃ and the time is 30 minutes to 2 hours. For dense medicinal materials, the temperature is set at 80-120℃ and the time is 3-6 hours. During the process, deviations are corrected in real time through infrared temperature measurement and humidity monitoring to ensure that the processing conditions remain stable.

[0059] This implementation method overcomes the limitations of traditional processing methods, which rely on experience and are difficult to quantify, achieving precision and stability in the transformation of medicinal properties. Intelligent temperature control equipment, combined with infrared thermometry, replaces the subjective judgment of observing the color of the fire and relying on touch, controlling temperature errors within ±2℃. This prevents excessively high temperatures from damaging effective components such as polysaccharides and volatile oils, or excessively low temperatures from causing insufficient processing. The 30-minute to 6-hour time range adapts to the transformation needs of different medicinal materials; for example, short periods at low temperatures can complete the roasting of tangerine peel, while long periods at high temperatures can reduce the toxicity of aconite. A 10:1 to 10:3 ratio of excipients ensures synergistic effects while avoiding excessive excipients masking the original flavor of the medicinal materials. For example, processing Polygonum multiflorum with black bean juice at a 10:3 ratio enhances its blood-tonifying effects without making the medicinal taste too astringent, ensuring consistent processing effects for each batch of medicinal materials and solving the problem of inconsistent efficacy of the same medicine in traditional processing.

[0060] Meanwhile, this implementation method also ensures the quality of subsequent processes and finished products, achieving a fusion of traditional techniques and modern standards. Precisely processed medicinal materials have more stable medicinal properties, and subsequent deep cleaning is less likely to result in the loss of effective components due to uneven medicinal properties. Slow soaking and prolonged steeping, combined with high-heat decoction, can more efficiently dissolve core components. Standardization in the selection of excipients and parameter settings makes the processing process traceable and reproducible, meeting the standardized requirements of modern TCM production. Furthermore, the detoxification effect is more controllable; for example, using 100-120℃ high temperature combined with vinegar processing of Aconitum carmichaelii can significantly reduce aconitine content and improve the safety of the finished herbal paste. This model, combining ancient theory with modern technology, inherits the TCM wisdom of using wine to enhance the medicinal properties and vinegar to nourish the liver, while adapting traditional techniques to large-scale production, meeting modern consumers' demands for safe and controllable health products.

[0061] As one implementation method, the graded cleaning method in step (3) is as follows: hard medicinal materials are ultrasonically cleaned for 5-10 minutes, loose medicinal materials are rinsed with running water for 3-5 minutes, medium-quality medicinal materials are soaked and cleaned for 8-12 minutes, and the natural draining time is 2-4 hours. During the draining process, pressure should be avoided on the medicinal materials.

[0062] Based on the core classification standard of medicinal materials, the materials are first classified according to their texture through manual screening or mechanical sorting: hard medicinal materials such as roots and stems and minerals are grouped into one category; loose medicinal materials such as leaves and flowers are grouped into another; and medium-textured medicinal materials such as fruits and seeds are grouped into a third. After classification, different cleaning methods are used accordingly: hard medicinal materials are placed in an ultrasonic cleaning device, and after setting the power and frequency, they are continuously cleaned for 5-10 minutes to use ultrasonic vibration to remove mud and impurities from the surface and crevices of the medicinal materials; loose medicinal materials are placed in a running water cleaning tank, and the water flow is adjusted to a gentle state, rinsing with continuously flowing clean water for 3-5 minutes to avoid damaging the structure of the medicinal materials with excessively strong water flow; medium-textured medicinal materials are placed in a clean soaking container, and the standard cleaning water is added to cover the medicinal materials. After soaking for 8-12 minutes, they are gently stirred to remove floating impurities. After all the medicinal materials are cleaned, they are transferred to a perforated mesh rack or filter cloth and allowed to air dry naturally in a cool, ventilated place for 2-4 hours. During the air-drying process, the water is drained by gravity only, and the medicinal materials are not treated by squeezing or pressing.

[0063] This approach tailors cleaning methods to different textures of medicinal herbs, overcoming the drawbacks of single cleaning methods. For example, ultrasonic cleaning of loose herbs can easily lead to breakage, while running water alone is insufficient to remove deep impurities from hard herbs, and soaking alone can cause loss of active ingredients due to improper time. Furthermore, precise control of cleaning time ensures that hard herbs are thoroughly cleaned, loose herbs are not damaged, and herbs of medium texture maintain a balance between cleanliness and ingredient retention. The natural, pressureless draining process prevents cell rupture due to external force, avoiding the loss of active ingredients with the liquid. This solves the problem of ingredient loss caused by forceful draining after traditional cleaning, while also preserving the integrity of the herbs, laying a good foundation for subsequent processing and soaking stages.

[0064] The cleaned medicinal herbs have extremely low impurity residue, eliminating the need for additional impurity removal steps in subsequent processes and reducing process redundancy. After cleaning, the moisture content of herbs of different textures is uniform. Hard herbs absorb water appropriately after ultrasonic cleaning, while porous herbs are not overly wet after running water cleaning. Medium-textured herbs have controllable moisture content after soaking. This ensures that all herbs are simultaneously and fully soaked without becoming moldy during the slow soaking process, preventing abnormal moisture content in some herbs from affecting extraction efficiency. Furthermore, clean herbs reduce impurity precipitation during subsequent high-heat decoction and low-heat simmering stages, lowering the filtration pressure in the extraction process and ultimately improving the clarity and taste of the finished herbal paste.

[0065] As one implementation method, in step (4), the low temperature environment temperature is 0-10℃, the auxiliary solvent is selected from one or more of pure water, yellow wine, and rice wine, the weight-volume ratio of medicinal material to auxiliary solvent is 1g:3-8mL, and the mixture is stirred once every 3-4 hours during the soaking process, with a stirring rate of 30-50r / min.

[0066] First, maintain a low-temperature environment of 0-10℃ using a constant-temperature refrigerator or a sealed soaking tank with intelligent temperature control. Monitor the temperature in real time to avoid fluctuations and prevent excessively high ambient temperatures from causing mold growth or loss of active ingredients in the medicinal materials. Then, select the auxiliary solvent according to the characteristics of the medicinal materials. For example, use purified water to ensure the purity of the components for root and rhizome medicinal materials. Use yellow rice wine for medicinal materials that need to enhance blood circulation and herbs that need to be milder. Alternatively, you can mix the two solvents as needed. Then, add the solvent at a ratio of 3-8 mL of solvent per 1 g of medicinal material. For example, add 3-8 L of solvent when processing 1 kg of medicinal materials, ensuring that the solvent completely covers the surface of the medicinal materials by 1-2 cm to avoid local exposure of the medicinal materials. During the soaking process, use a low-speed stirrer, starting it every 3-4 hours and controlling the stirring speed at 30-50 r / min. Gently stir the solvent and medicinal materials to prevent the medicinal materials from breaking due to vigorous stirring and to prevent the solvent from separating and causing uneven soaking.

[0067] The low-temperature environment of 0-10℃ can inhibit the growth of microorganisms such as bacteria and mold, preventing the herbs from deteriorating during prolonged soaking. It also protects the heat-sensitive components in the herbs from being destroyed by high temperatures, reducing the loss of effective ingredients by 15%-20% compared to soaking at room temperature. The low-speed timed stirring at 30-50r / min allows the solvent to penetrate evenly into the herbs. Especially for herbs with a dense texture, it can break down the concentration barrier formed by the solvent on the surface of the herbs, allowing the intercellular spaces to gradually fill with solvent, avoiding the situation of external wetness and internal dryness that occurs with traditional static soaking. The solvent ratio of 1g:3-8mL ensures that the herbs are sufficiently wetted by the solvent without causing the concentration to be too low during subsequent decoction due to excessive solvent, thus reducing energy waste.

[0068] The fully soaked medicinal herbs have undergone initial softening of their cell structure, allowing for faster dissolution of active ingredients during the high-heat decoction stage. This increases decoction efficiency by 20%-30% and ensures more complete dissolution, reducing raw material waste. Standardized solvent selection and stirring operations ensure reproducible soaking effects for each batch of herbs, avoiding frequent adjustments to subsequent process parameters due to soaking differences. This aligns with the standardization and large-scale production requirements of modern TCM. Furthermore, low-temperature soaking and gentle handling maintain the integrity of the herbs, minimizing residue buildup during subsequent filtration and decoction processes. This reduces the difficulty of filtering and extracting the essence, resulting in a finished paste with fewer impurities and a more delicate taste. This approach not only continues the traditional concept of slow extraction of essence but also ensures more controllable and safer quality through modern parameter control.

[0069] In one implementation method, the heating temperature in step (5) is 100-120℃, the decoction time is 30-90 minutes each time, the interval between two adjacent decoctions is 20-40 minutes, the amount of water added per 1kg of medicinal material is 5-10L, and the decoction is kept in a state of gentle boiling to avoid violent boiling.

[0070] The decoction method employs a standardized operating procedure based on precise temperature control, quantitative water addition, and staged extraction. First, an electric heating decoction pot or gas-fired stove with intelligent temperature control is selected. The heating temperature is set to 100-120℃ through the equipment's temperature control system, while a temperature monitoring instrument provides real-time feedback on the liquid temperature, ensuring the temperature remains stable within the set range during heating. The total water volume is calculated based on a ratio of 5-10L of water per 1kg of medicinal materials. Half the water volume is added to the decoction container, followed by the pre-treated medicinal materials, which are stirred thoroughly. The remaining water is then added to the standard mark, ensuring the medicinal materials are completely submerged and the liquid level is 3-5 cm above the materials. Turn on the heating equipment to high heat. Once the liquid boils, reduce to a gentle simmer, keeping the surface of the liquid slightly agitated without overflowing. Stir gently every 15-20 minutes to prevent scorching. Each decoction should last 30-90 minutes, adjusting the time according to the texture of the herbs: 30-60 minutes for loose herbs and 60-90 minutes for hard herbs. After the first decoction, turn off the high heat and let the liquid stand naturally for 20-40 minutes, keeping the container warm to prevent sudden cooling from affecting subsequent extractions. Repeat the heating, simmering, and timing process 2-4 times, collecting the liquid after each decoction for later use.

[0071] A high temperature of 100-120℃ quickly brings the decoction to a gentle boil, accelerating the penetration of water molecules into the medicinal cell and promoting the dissolution of water-soluble active ingredients such as alkaloids, polysaccharides, and saponins. Compared to slow decoction at low temperatures, the dissolution rate can be increased by 40%-50%. The precise calculation of a single decoction time of 30-90 minutes ensures the full dissolution of active ingredients while avoiding the destruction of heat-sensitive components due to prolonged high temperatures. A 20-40 minute interval of resting allows the medicinal material to shrink during the brief cooling process, making it easier for the intercellular spaces to absorb water upon reheating, further releasing residual components. Repeated decoctions of 2-4 times can cover components with different solubilities. For example, the first decoction mainly dissolves water-soluble components, while subsequent decoctions can extract insoluble components or those adsorbed on the cell walls, increasing the utilization rate of the medicinal material by 25%-30% and reducing raw material waste.

[0072] The standardized water addition of 5-10L per 1kg of medicinal herbs ensures that the concentration of the decoction remains within a reasonable range after each decoction. This avoids excessive water leading to prolonged simmering time and increased energy consumption, or insufficient water causing the decoction to become too concentrated and burnt. Strict control of the gentle boiling process prevents splashing and component loss due to violent boiling, and also avoids localized overheating that produces charring, reducing the burden on impurity handling during subsequent filtration and extraction. Furthermore, the fully parameterized operation mode makes the decoction process traceable and reproducible, controlling the variation in effective component content between batches of decoction to within 5%.

[0073] In one implementation method, the heating temperature in step (6) is 60-90℃, the cooking time is 2-6 hours, the concentration method is atmospheric pressure concentration or vacuum concentration, the vacuum degree is 0.05-0.09MPa during vacuum concentration, and the relative density of the concentrated liquid is 1.1-1.3 at 25℃.

[0074] First, select the concentration equipment based on the characteristics of the medicinal liquid: If the liquid contains volatile components or requires high-efficiency concentration, choose a vacuum concentration tank with intelligent temperature control. After sealing, adjust the vacuum level to 0.05-0.09 MPa using a vacuum pump. If the liquid has stable components and no special volatility requirements, use an open-top, low-heat decoction pot for atmospheric pressure concentration. For both methods, set the heating temperature to 60-90℃ using the equipment's temperature control system. Adjust the decoction time according to the initial viscosity of the liquid. Decoct the initially collected diluted liquid for 4-6 hours, and the thickened liquid after multiple decoctions for 2-4 hours. Stir gently with a stirring paddle every 30 minutes during decoction to prevent localized overheating and scorching. Take samples periodically and use a hydrometer at 25℃ to measure the relative density of the liquid until it reaches 1.1-1.3, then stop heating to complete the concentration.

[0075] The low temperature range of 60-90℃ avoids the destruction of heat-sensitive active ingredients such as polysaccharides and flavonoids by high temperatures. Compared with the traditional boiling process exceeding 100℃, the retention rate of active ingredients is increased by 15%-20%. During vacuum concentration, the vacuum level of 0.05-0.09MPa lowers the boiling point of the liquid, allowing concentration to be completed at a lower temperature, further reducing the loss of volatile components and shortening the boiling time by 1-2 hours, thus reducing energy consumption. Furthermore, adjusting the concentration time according to the viscosity of the liquid avoids insufficient concentration due to insufficient time for thin liquids, while preventing carbonization of components due to excessive time for thick liquids. This ensures the stable content of active ingredients in each batch of concentrated liquid, solving the problem of component loss caused by relying on experience to judge viscosity in traditional methods.

[0076] A relative density of 1.1-1.3 at 25℃ is a key standard. Too low a density requires extended heating time during the final concentration process, potentially leading to secondary loss of components; too high a density may cause premature solidification, making it difficult to mix evenly with excipients. Flexible concentration methods can adapt to different formulation needs. For example, vacuum concentration is used for pastes containing precious volatile components, while normal pressure concentration is used for conventional health-preserving pastes, ensuring process compatibility while controlling production costs. This standardized parameter control ensures consistent state for each batch of liquid, avoiding quality fluctuations associated with traditional processes.

[0077] In one implementation method, the multi-stage filtration in step (7) sequentially employs gauze filtration, filter paper filtration, and ultrafiltration membrane filtration. The pore size of the ultrafiltration membrane is 0.1-1μm, the settling time for the precipitation operation is 1-3 hours, and after filtration, centrifugation can be selectively performed. The centrifugation speed is 3000-5000r / min, and the centrifugation time is 10-20 minutes.

[0078] First, transfer the concentrated medicinal liquid after simmering over low heat to a sealed, clean container and let it stand in a cool, ventilated place for 1-3 hours, allowing large suspended particles to settle naturally to the bottom of the container. After standing, filter the liquid through gauze by slowly pouring it into a funnel lined with double layers of medical gauze, using gravity to remove coarse impurities such as lumps and fibers, and collect the pre-filtered liquid. Next, filter the liquid through filter paper using medium-speed qualitative filter paper, pouring the pre-filtered liquid into a filter paper funnel to remove smaller suspended solids. Finally, filter the liquid through an ultrafiltration membrane using an ultrafiltration membrane module with a pore size of 0.1-1μm, slowly pumping the filtered liquid through the filter paper to the membrane system to trap small particles and large molecular impurities, and collect the permeate. If the clarity of the drug solution still does not meet the standard, centrifugation can be selectively performed: pour the ultrafiltered drug solution into a centrifuge tube, put it in a centrifuge and set the speed to 3000-5000r / min, and continue centrifuging for 10-20 minutes to allow the residual trace impurities to settle under the action of centrifugal force, and finally collect the upper clear drug solution.

[0079] The pre-sedimentation and settling design allows 60%-70% of coarse impurities to separate in advance, preventing clogging of gauze, filter paper, or ultrafiltration membranes during subsequent filtration, significantly improving filtration efficiency and reducing the frequency of filter media replacement. The three-stage filtration from gauze to filter paper to ultrafiltration membrane covers impurities ranging from millimeters to micrometers. Compared to traditional single gauze filtration, the impurity removal rate is increased by more than 80%. The pore size of the 0.1-1μm ultrafiltration membrane is precisely calculated to retain both tiny impurities that affect the clarity of the paste and small-molecule active ingredients in the medicinal materials, achieving an effective ingredient retention rate of over 95%. Optional centrifugation is used as a supplementary method to address the problem of trace impurities in the medicinal solution that are difficult to remove by filtration due to their similar density to the medicinal solution, further improving the purity of the medicinal solution and avoiding sedimentation and stratification during the storage of the paste after traditional filtration.

[0080] When the clarification of the medicinal liquid meets the standard, it can be evenly mixed with the excipients during the paste-making stage, avoiding spots and a grainy texture caused by impurities, and ensuring that the finished paste meets the standard of a mirror-like appearance. The deep removal of impurities can reduce the carriers for microbial growth, reduce the risk of spoilage during the storage of the paste, and indirectly extend the shelf life by 1-3 months. The parameters of the entire filtration process are clear and controllable, so that the purification effect of each batch of medicinal liquid can be reproduced, solving the quality fluctuation problem caused by relying on the naked eye to judge the clarity of traditional filtration.

[0081] In one implementation method, the excipients in step (8) are selected from at least one of honey, rock sugar, donkey-hide gelatin, and deer antler gelatin. The weight ratio of the medicinal liquid to the excipients is 5:1 to 5:3. The specific temperature differences in the four seasons are as follows: the temperature for collecting the paste is 55-60℃ in spring, 50-55℃ in summer, 60-65℃ in autumn, and 65-70℃ in winter. The standard for picking out the paste into threads is that when the paste is picked up with bamboo chopsticks, it forms a continuous thread of 2-3 cm. The final relative density of the paste is 1.3-1.5 at 25℃.

[0082] First, select the auxiliary ingredients according to the efficacy and taste requirements of the herbal paste: if the focus is on nourishing qi and blood, choose donkey-hide gelatin or deer antler gelatin; if the focus is on flavoring and preservation, choose honey or rock sugar; they can also be combined, such as donkey-hide gelatin and honey in a 1:1 ratio. Calculate the dosage according to a weight ratio of medicinal liquid to auxiliary ingredients of 5:1-5:3. For example, use 1-3 kg of auxiliary ingredients for 5 kg of concentrated medicinal liquid. Pre-treat the auxiliary ingredients in advance. Melt the donkey-hide gelatin and deer antler gelatin in a double boiler. Heat the honey and rock sugar until completely dissolved, then slowly pour them into the medicinal liquid and stir evenly. Next, adjust the temperature for reducing the paste according to the season: in spring, use intelligent temperature control equipment to stabilize the temperature at 55-60℃; in summer, adjust to 50-55℃; in autumn, control to 60-65℃; and in winter, raise to 65-70℃. Maintain a low simmer throughout the process and stir continuously to prevent localized burning. During the paste-making process, periodic checks are performed: use bamboo chopsticks to dip a small amount of paste and observe whether continuous strands of 2-3 cm are formed; at the same time, use a densitometer to measure the relative density of the paste at 25℃ until the value reaches 1.3-1.5, then stop heating to complete the paste-making process.

[0083] The seasonal temperature settings are based on precise adaptation to the ambient temperature and humidity of different seasons. In summer, when the ambient temperature is high, a low temperature of 50-55℃ is used to concentrate the paste, preventing it from becoming sandy or deteriorating due to overheating. In winter, when the ambient temperature is low, a slightly higher temperature of 65-70℃ ensures that the paste is fully concentrated and formed, preventing it from becoming too thin and difficult to store due to insufficient temperature, thus maintaining the consistent quality of the paste made in different seasons. The 5:1 to 5:3 ratio of excipients balances efficacy and taste. For example, adding donkey-hide gelatin and deer antler gelatin in the correct proportions can significantly enhance the nourishing effect, while honey and rock sugar can neutralize the bitterness of the herbs and prevent excessive excipients from masking the original flavor of the herbs or making the paste too sweet.

[0084] A relative density of 1.3-1.5 at 25℃ allows the paste to form a stable colloidal structure, preventing microbial growth due to excessive thinness and ensuring it dissolves easily when ingested due to excessive thickness. This extends shelf life and makes it convenient for users to take. The excipients are selected from food and medicine homologous ingredients such as honey and donkey-hide gelatin, which aligns with the traditional Chinese medicine concept of food and medicine sharing the same origin, while also meeting modern consumers' demands for safety and natural ingredients, avoiding health concerns arising from artificial additives.

[0085] As one implementation method, it also includes adding probiotics during the paste-making stage, with the amount of probiotics added being 0.01%-0.1% of the total weight of the paste. The probiotics are selected from at least one of Bifidobacterium and Lactobacillus. Alternatively, the proportion of principal, assistant, and adjuvant herbs in the formula can be adjusted according to the modern physique, wherein the amount of qi-tonifying herbs can be increased by 10%-20%, and the amount of heat-clearing herbs can be reduced by 5%-15%. The shelf life of the finished paste is not less than 18 months, and the loss rate of effective ingredients during storage does not exceed 10%.

[0086] During the paste-making stage, once the paste temperature drops below 40℃, probiotics are added at a ratio of 0.01%-0.1% of the total paste weight. Stable Bifidobacterium or Lactobacillus are preferred. If enhanced intestinal regulation is desired, a single probiotic can be added; otherwise, a mixture is used to address both digestion and immunity. After addition, gently stir with a low-speed mixer for 5-10 minutes to ensure even distribution of the probiotics without localized aggregation. Regarding the adjustment of the herbal formula, common constitution characteristics of modern populations are first summarized through TCM constitution identification. Then, the proportions of principal, assistant, and adjuvant herbs are optimized: Qi-tonifying herbs are increased by 10%-20% compared to the original formula, while heat-clearing herbs are reduced by 5%-15%. After adjustment, small-batch trial production is conducted to verify the efficacy and compatibility. Simultaneously, food-grade sealed packaging is used, and the storage environment temperature is controlled between 5-25℃ and relative humidity ≤60%. The content of active ingredients is regularly tested using high-performance liquid chromatography to ensure that the finished paste has a shelf life of no less than 18 months, with the loss rate of active ingredients controlled within 10% during storage.

[0087] The addition of probiotics directly addresses the gut microbiota imbalance caused by irregular eating habits and sedentary lifestyles in modern people. Bifidobacteria or lactobacilli can colonize the intestines, promoting the breakdown and absorption of effective ingredients such as polysaccharides and saponins in the herbal paste. Compared to traditional herbal pastes without probiotics, the body's utilization rate of nutrients increases by 15%-20%, while also alleviating discomfort such as bloating and indigestion that may occur in some people after taking the herbal paste. The adjustment of the proportion of medicinal materials is based on the changes in the constitution of modern people: compared with traditional populations, modern people often have excess Qi and insufficient internal heat. Adding Qi-tonifying herbs can enhance the energy regulation and immune-boosting effects of the herbal paste, while reducing heat-clearing herbs can avoid the coldness that can damage the spleen and reduce the risk of diarrhea in people with weak spleen and stomach.

[0088] With a shelf life of no less than 18 months, it solves the problem of traditional herbal pastes being prone to short-term spoilage, making it convenient for consumers to store for a long time and take it as needed without frequent preparation; the loss rate of effective ingredients is controlled within 10%, and through the optimization of packaging and storage conditions, it avoids the reduction of efficacy of traditional herbal pastes due to improper storage, ensuring that consumers take highly active herbal pastes throughout the entire process.

[0089] Example

[0090] To verify the beneficial effects of the process of the present invention, a classic herbal paste with the function of invigorating qi and nourishing blood (main components: astragalus, angelica, codonopsis, rehmannia, etc.) was prepared by traditional experience process (comparative example) and the process described in the present invention (example), and the key indicators were compared.
