Description

Technical Field

[0001] This invention relates to the field of aromatherapy preparation technology, specifically to an aromatherapy moxibustion with low plant tar release and its preparation method. Background Technology

[0002] Moxibustion is a traditional Chinese medicine external therapy made from natural plants. When burned, the warm smoke and volatile components of the herbs work synergistically to warm and unblock the meridians, regulate qi and blood, and dispel cold and relieve pain. Traditional moxibustion often uses mugwort leaves as the main ingredient, which produces a large amount of plant tar during combustion. Plant tar is a viscous organic mixture formed by the thermal decomposition of plant tissues. It easily adheres to the respiratory mucosa, causing discomfort such as dry throat, cough, and chest tightness. It also pollutes the indoor environment, affecting the safe application and promotion of moxibustion.

[0003] To address the high tar release rate of traditional incense moxibustion, existing technologies primarily employ three improvement approaches: First, adding chemical smoke suppressants and combustion aids fails to inhibit tar formation at its source and easily introduces harmful substances such as formaldehyde and heavy metals, contradicting the principles of natural herbs and lacking safety. Second, high-temperature carbonization, while reducing tar release, significantly damages plant volatile oils, flavonoids, polysaccharides, and other effective components, leading to a substantial decrease in the efficacy of incense moxibustion. Third, simply combining sandalwood, agarwood, and other single aromatic herbs only improves the odor of the smoke and has no substantial inhibitory effect on tar formation, failing to fundamentally solve the problem of high tar release.

[0004] Therefore, the market urgently needs a natural, non-toxic, low-tar release, and stable moxibustion product to solve the technical problems of high tar content and insufficient safety in traditional moxibustion, and promote the green and safe development of the moxibustion industry. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a low-plant tar release moxibustion and its preparation method. By compounding specific medicinal materials, mainly herbal plants and supplemented with woody leafy medicinal materials, multiple natural plants are used to synergistically inhibit the formation of plant tar and harmonize the medicinal properties, achieving the technical effects of low plant tar release, mild and fresh aroma, stable moxibustion effect, and natural safety, thus meeting the needs of modern indoor aromatherapy and safe use by sensitive groups.

[0006] This invention provides a low-tar release aromatherapy moxibustion, the composition of which, by weight, includes: 5-10 parts of monk fruit, 5-10 parts of loquat leaf, 5-10 parts of mulberry leaf, 5-10 parts of chrysanthemum, 5-10 parts of green tea, 5-10 parts of licorice, 5-10 parts of peppermint, 4-8 parts of mugwort leaf, and 2-5 parts of perilla.

[0007] Preferably, the components of the moxibustion, by weight, include: 7.5 parts of monk fruit, 7.5 parts of loquat leaf, 7.5 parts of mulberry leaf, 7.5 parts of chrysanthemum, 7.5 parts of green tea, 7.5 parts of licorice, 7.5 parts of peppermint, 6 parts of mugwort leaf, and 3.5 parts of perilla.

[0008] This invention also provides a method for preparing incense moxibustion, the method comprising the following steps: S1. Put the preset amounts of monk fruit, loquat leaves, mulberry leaves, chrysanthemum, green tea, licorice, mint, mugwort leaves and perilla into the cell wall breaking and pulverizing equipment and pulverize them to obtain raw powder of 350-500 mesh. S2. Place the raw powder in a ventilated environment at 20-30℃ and ferment for at least 100 days to obtain fermented powder; S3. Put the fermentation powder into a hot air circulating drying equipment, set the drying temperature to 50-80℃, dry for 20-24 hours, and dry until the moisture content of the fermentation powder is 8%-10% to obtain dried powder. S4. The dried powder is processed into filamentous material with a diameter of 0.2-0.4 mm; S5. The filamentous material is evenly rolled into packaging paper to obtain the finished incense moxibustion product.

[0009] Specifically, step S1 also includes: After removing the shell from the monk fruit, the pulp and shell are crushed separately. The crushed shell is passed through a 350-mesh sieve, and the crushed pulp is passed through a 500-mesh sieve.

[0010] Specifically, step S1 also includes: The loquat leaves, mulberry leaves, and mugwort leaves are placed in a low-temperature oven at 40-50℃ for 2-3 hours, cooled, and then pulverized.

[0011] Specifically, step S2 also includes: A fermentation agent is added to the original powder. The amount of the fermentation agent added is 0.5%-1% of the total mass of the original powder. The fermentation agent is made by mixing yeast and lactic acid bacteria in a 1:1 mass ratio.

[0012] Specifically, step S2 also includes: During the fermentation process, the mixture is turned over once every 20 days for 10-15 minutes, and the relative humidity of the fermentation environment is controlled at 60%-70%.

[0013] Specifically, before step S4, the following steps are also included: An auxiliary additive is added to the dried powder. The amount of the auxiliary additive is 2%-3% of the total mass of the dried powder. The auxiliary additive is made by mixing corn starch and activated carbon powder in a mass ratio of 2:1.

[0014] Specifically, in step S5, the roll density of the filamentous material is controlled to be 0.8-1.0 g / cm³. 3 The packaging paper is made of cotton paper or mulberry bark paper.

[0015] Specifically, before step S5, the following steps are also included: Apply peppermint leaf extract to the packaging paper and let it dry for later use. The amount of peppermint leaf extract applied is 1%-2% of the weight of the packaging paper.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The aromatherapy formula of this invention mainly uses natural plant raw materials, primarily herbal plants supplemented with woody leafy medicinal materials. The components work synergistically to inhibit the formation of plant tar at its source, effectively reducing the amount of plant tar released during combustion. Specifically, green tea is rich in tea polyphenols, which can inhibit the thermal decomposition of plant lignin and cellulose, reducing the formation of tar precursors. Monk fruit, loquat leaves, and mulberry leaves are rich in flavonoids, polysaccharides, and organic acids, which can decompose during combustion to produce weakly oxidizing small molecules, inhibiting the polymerization of polycyclic aromatic hydrocarbons and further reducing plant tar formation. Peppermint and perilla volatile oils have low boiling points and volatilize first during combustion, diluting the concentration of plant tar and reducing plant tar adhesion. This results in a significantly lower release of plant tar in the finished aromatherapy product compared to traditional aromatherapy, with milder smoke and significantly reduced irritation.

[0017] The aromatherapy formula of this invention features a rational combination of medicinal materials and synergistic effects, resulting in a comprehensive and stable therapeutic effect. Artemisia argyi, as the core ingredient, plays a fundamental role in warming and unblocking the meridians, dispelling cold, and relieving pain. Loquat leaf and mulberry leaf work together to clear the lungs, moisten dryness, reduce phlegm, and alleviate the irritation of smoke on the throat. Monk fruit and licorice clear heat, soothe the throat, harmonize the effects of other herbs, moderate their properties, and reduce the feeling of heat. Chrysanthemum and green tea clear heat, reduce fire, calm the mind, and balance the warming properties of artemisia argyi. Peppermint and perilla provide aromatic relief, regulate qi, and alleviate depression, improving the smell of smoke while enhancing user comfort. The synergistic effect of these multiple herbs gives the aromatherapy a combination of warming, moistening, heat-clearing, and calming effects, resulting in an overall therapeutic effect superior to traditional single-ingredient artemisia argyi aromatherapy.

[0018] The aromatherapy formula of this invention contains no chemical smoke suppressants, combustion aids, fragrances, or heavy metals. The combustion smoke leaves no harmful residues such as formaldehyde or benzene, making it natural, non-toxic, and highly safe. It is suitable for long-term use in enclosed spaces, by the elderly, children, and those with respiratory sensitivities. Meanwhile, peppermint provides a cool and elegant aroma, while chrysanthemum and green tea impart a refreshing herbal fragrance, effectively neutralizing the slightly bitter aroma of mugwort. The smoke is fresh and free of pungent odors, leaving a gentle and long-lasting fragrance indoors, significantly improving the aromatherapy environment and enhancing the user experience and compliance. This effectively meets the safety needs of modern indoor aromatherapy and sensitive individuals. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a schematic flowchart of the preparation method of the incense moxibustion in an embodiment of the present invention. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a low-tar release aromatherapy moxibustion, the composition of which, by weight, includes: 5-10 parts of monk fruit, 5-10 parts of loquat leaf, 5-10 parts of mulberry leaf, 5-10 parts of chrysanthemum, 5-10 parts of green tea, 5-10 parts of licorice, 5-10 parts of peppermint, 4-8 parts of mugwort leaf, and 2-5 parts of perilla.

[0023] The aromatherapy formula of this invention mainly uses natural plant raw materials, primarily herbal plants supplemented with woody leafy medicinal materials. The components work synergistically to inhibit the formation of plant tar at its source, effectively reducing the amount of plant tar released during combustion. Specifically, green tea is rich in tea polyphenols, which can inhibit the thermal decomposition of plant lignin and cellulose, reducing the formation of tar precursors. Monk fruit, loquat leaves, and mulberry leaves are rich in flavonoids, polysaccharides, and organic acids, which can decompose during combustion to produce weakly oxidizing small molecules, inhibiting the polymerization of polycyclic aromatic hydrocarbons and further reducing plant tar formation. Peppermint and perilla volatile oils have low boiling points and volatilize first during combustion, diluting the concentration of plant tar and reducing plant tar adhesion. This results in a significantly lower release of plant tar in the finished aromatherapy product compared to traditional aromatherapy, with milder smoke and significantly reduced irritation.

[0024] Moreover, the medicinal materials in the aromatherapy formula of this invention are rationally combined and synergistically effective, resulting in a comprehensive and stable therapeutic effect. Artemisia argyi, as the core ingredient, plays a fundamental role in warming and unblocking the meridians, dispelling cold, and relieving pain. Loquat leaves and mulberry leaves work together to clear the lungs, moisten dryness, reduce phlegm, and alleviate the irritation of smoke on the throat. Monk fruit and licorice clear heat, soothe the throat, harmonize the effects of the other herbs, moderate their properties, and reduce the feeling of heat. Chrysanthemum and green tea clear heat, reduce fire, calm the mind, and balance the warming properties of artemisia argyi. Peppermint and perilla provide aromatic relief, regulate qi, and alleviate depression, improving the smell of smoke while enhancing user comfort. The synergistic effect of these multiple herbs gives the aromatherapy the combined effects of warming, moistening the lungs, clearing heat, and calming the mind, resulting in an overall therapeutic effect superior to traditional single-ingredient artemisia argyi aromatherapy.

[0025] Furthermore, the aromatherapy formula of this invention does not contain any chemical smoke suppressants, combustion aids, fragrances, or heavy metals. The combustion smoke leaves no harmful residues such as formaldehyde or benzene, making it natural, non-toxic, and highly safe. It is suitable for long-term use in enclosed spaces, by the elderly, children, and people with respiratory sensitivities. Meanwhile, peppermint provides a cool and elegant aroma, while chrysanthemum and green tea impart a refreshing herbal fragrance, effectively neutralizing the slightly bitter aroma of mugwort. The smoke is fresh and free of pungent odors, leaving a gentle and long-lasting fragrance indoors, significantly improving the aromatherapy environment and enhancing the user experience and compliance. This effectively meets the safety needs of modern indoor aromatherapy and sensitive individuals.

[0026] Optional ingredients include: monk fruit (5 parts, 7.5 parts, or 10 parts); loquat leaf (5 parts, 7.5 parts, or 10 parts); mulberry leaf (5 parts, 7.5 parts, or 10 parts); chrysanthemum (5 parts, 7.5 parts, or 10 parts); green tea (5 parts, 7.5 parts, or 10 parts); licorice root (5 parts, 7.5 parts, or 10 parts); mint (5 parts, 7.5 parts, or 10 parts); mugwort leaf (4 parts, 6 parts, or 8 parts); and perilla leaf (2 parts, 3.5 parts, or 5 parts).

[0027] Preferably, the components of the moxibustion, by weight, include: 7.5 parts monk fruit, 7.5 parts loquat leaf, 7.5 parts mulberry leaf, 7.5 parts chrysanthemum, 7.5 parts green tea, 7.5 parts licorice, 7.5 parts peppermint, 6 parts mugwort, and 3.5 parts perilla. This preferred combination takes into account both production cost and usage effect.

[0028] This invention also provides a method for preparing aromatherapy moxibustion. Figure 1 A schematic flowchart of the preparation method of the incense moxibustion according to an embodiment of the present invention is shown. The preparation method includes the following steps: S1. Put the preset amounts of monk fruit, loquat leaves, mulberry leaves, chrysanthemum, green tea, licorice, mint, mugwort leaves and perilla into the cell wall breaking and pulverizing equipment and pulverize them to obtain raw powder of 350-500 mesh. The process of breaking down and pulverizing the plant cells into a raw powder of 350-500 mesh breaks down the plant cell walls, fully releasing the effective components such as flavonoids, tea polyphenols, and volatile oils within the medicinal materials. Simultaneously, it ensures uniform mixing of all medicinal materials, preventing uneven tar formation caused by excessively high local component concentrations. This creates a homogeneous material base for subsequent fermentation and synergistic effects. Optionally, the particle size of the raw powder can be 350 mesh, 400 mesh, 450 mesh, 500 mesh, or a mixture of multiple mesh sizes.

[0029] In some specific embodiments, step S1 further includes: after removing the shell from the monk fruit, crushing the pulp and shell separately, passing the crushed shell through a 350-mesh sieve, and passing the crushed pulp through a 500-mesh sieve.

[0030] The shell of monk fruit is hard and high in fiber, making it an important carrier of tar precursors. Pulverizing it and passing it through a 350-mesh sieve refines the hard fibers to a suitable particle size. This avoids the incomplete thermal decomposition of large fiber particles during combustion, preventing the generation of large amounts of plant tar, while retaining the flavonoids, polysaccharides, and other effective components in the shell, ensuring its efficacy in inhibiting the polymerization of polycyclic aromatic hydrocarbons and reducing tar formation. The pulp of monk fruit is rich in fructose, organic acids, and various active ingredients. Its soft and glutinous texture allows for easy extraction of active ingredients. Pulverizing it and passing it through a 500-mesh sieve further refines the pulp particles, allowing it to fully integrate with other medicinal powders. During combustion, the organic acids in the pulp rapidly decompose to produce weakly oxidizing small molecules, effectively inhibiting the polymerization of plant tar, while also enhancing its heat-clearing, throat-soothing, and mildening medicinal effects. In addition, the separate screening of fruit pulp and shell can avoid uneven mixing of coarse shell particles and fine fruit pulp particles, and prevent excessive differences in the physical and chemical properties of the materials during subsequent fermentation and drying, which could lead to abnormal local combustion and fluctuations in the release of plant tar. This ensures stable release of plant tar and uniform efficacy in the finished product of the incense and moxibustion, and fully leverages the dual value of monk fruit in the formula of inhibiting plant tar and harmonizing various medicines.

[0031] In some specific embodiments, step S1 further includes: placing the loquat leaves, mulberry leaves and mugwort leaves at a low temperature of 40-50℃ for 2-3 hours, cooling them and then crushing them.

[0032] Loquat leaves and mulberry leaves are rich in flavonoids, volatile oils, and organic acids, while mugwort leaves contain volatile oils, mugwort polysaccharides, and other active ingredients. Low-temperature baking at 40-50℃ is a gentle heat treatment that removes moisture and impurities from the surface of the herbs, reducing the initial moisture content and minimizing energy and time consumption in subsequent drying processes. It also prevents high-temperature baking from damaging the heat-sensitive volatile oil components in these three herbs, preserving their core effects of clearing the lungs, moisturizing dryness, warming the meridians, and regulating qi and relieving depression. Low-temperature baking also moderately softens the fibrous tissue of leafy herbs, reducing the difficulty of subsequent cell wall breaking and pulverization, resulting in more uniform particle size in the pulverized powder. This avoids the formation of coarse particles due to incomplete pulverization caused by overly hard fibers, and prevents the incomplete thermal decomposition of coarse particles during combustion, which would generate large amounts of plant tar. Meanwhile, the baking process can slightly activate the active ingredients in the medicinal materials, enhance the ability of loquat leaves and mulberry leaves to inhibit plant tar polymerization and alleviate smoke irritation, strengthen the basic function of mugwort in warming and dispelling cold, remove the astringent taste of leafy medicinal materials, neutralize the slightly bitter aroma of mugwort, improve the smell of smoke, and avoid the problems of pungent smoke, high plant tar content, and weak medicinal efficacy caused by untreated leafy raw materials in traditional incense and moxibustion. This provides high-quality raw materials for subsequent fermentation, silk-making, and other processes. Optionally, it can be baked at a low temperature of 40℃ for 3 hours, or at a low temperature of 45℃ for 2.5 hours, or at a low temperature of 50℃ for 2 hours.

[0033] S2. Place the raw powder in a ventilated environment at 20-30℃ and ferment for at least 100 days to obtain fermented powder; Fermentation should be carried out for at least 100 days in a well-ventilated environment at 20-30℃. This gentle, long-term fermentation process allows microorganisms to decompose large molecules in the material, such as lignin and cellulose, which are prone to producing tar. This reduces tar precursors at the source, while also transforming some ineffective components, enhancing the activity of active ingredients, and avoiding the destruction of efficacy by high-temperature treatment. Alternatively, the raw powder can be fermented in a well-ventilated environment at 20℃, 22℃, 24℃, 26℃, 28℃, or 30℃.

[0034] In some specific embodiments, step S2 further includes: adding a fermentation agent to the original powder, wherein the amount of the fermentation agent added is 0.5%-1% of the total mass of the original powder, and the fermentation agent is made by mixing yeast and lactic acid bacteria in a 1:1 mass ratio.

[0035] Yeast and lactic acid bacteria are natural, mild, and beneficial microorganisms. A 1:1 ratio of yeast and lactic acid bacteria forms a synergistic fermentation system, suitable for a fermentation environment of 20-30℃, avoiding the problems of low fermentation efficiency and incomplete fermentation associated with single-strain fermentation. An addition of 0.5%-1% is appropriate for the total amount of original powder, ensuring sufficient microbial quantity and rapid reproduction without causing material spoilage or off-odors due to excessive microbial agents, thus balancing fermentation effect and safety. During fermentation, lactic acid bacteria decompose recalcitrant macromolecules such as lignin and cellulose in the material, converting them into smaller sugars and organic acids, reducing precursors to plant tar formation at the source. Simultaneously, it lowers the pH value of the material, inhibiting the growth of harmful microorganisms and preventing mold and spoilage. Yeast further decomposes smaller molecules, producing aromatic substances such as alcohols and esters, improving the odor of incense smoke, and activating effective components such as flavonoids and polysaccharides in medicinal materials, enhancing their medicinal activity. Compared to natural fermentation, adding this microbial agent can shorten the fermentation cycle and improve fermentation uniformity, avoiding problems such as insufficient fermentation in certain areas, excessive residue of tar precursors, or excessive fermentation in certain areas and loss of effective components. This ensures that the fermented powder has low tar precursor content, high activity of effective components, and a fresh aroma, providing high-quality materials for subsequent drying and silk-making processes. This guarantees the core advantages of the finished incense and moxibustion product: low tar content, excellent efficacy, and superior aroma. Optionally, the amount of fermentation agent added can be 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, or 1% of the total mass of the original powder.

[0036] In some specific embodiments, step S2 further includes: during the fermentation process, the mixture is turned over once every 20 days for 10-15 minutes, and the relative humidity of the fermentation environment is controlled at 60%-70%.

[0037] The optimal relative humidity range for the growth and reproduction of yeast and lactic acid bacteria is 60%-70%. Too low a humidity level leads to rapid moisture loss from the raw powder, causing the material to dry and clump, reducing microbial activity, halting the fermentation process, resulting in incomplete decomposition of lignin and cellulose, and leaving excessive tar precursors. Too high a humidity level, on the other hand, easily breeds mold and other harmful microorganisms, causing spoilage, off-odors, and damaging the effective components of the medicinal materials, thus affecting the safety and quality of the incense and moxibustion. This humidity range balances microbial activity and material stability, ensuring continuous and stable fermentation. Optionally, the relative humidity of the fermentation environment can be controlled at 60%, 62%, 64%, 66%, 68%, or 70%.

[0038] Stirring for 10-15 minutes every 20 days breaks up hardened surfaces, ensuring thorough mixing of the bottom, middle, and top layers of powder. This prevents uneven fermentation caused by excessive accumulation, insufficient ventilation, or uneven microbial distribution: surface materials are prone to over-fermentation due to air exposure, resulting in loss of active ingredients; while bottom materials are under-fermented due to lack of oxygen, leading to higher levels of tar precursors. Regular stirring ensures all powders are evenly exposed to microorganisms and oxygen, achieving comprehensive and synchronized fermentation. This ensures complete decomposition of lignin and cellulose in every batch, uniform reduction of tar precursor content, and uniform activation of active ingredients. It avoids issues such as fluctuating plant tar release, inconsistent efficacy, and significant odor differences in the finished incense and moxibustion product due to uneven fermentation, guaranteeing stable quality and consistent effects. Optionally, stirring can be done for 10, 11, 12, 13, 14, or 15 minutes every 20 days.

[0039] S3. Put the fermentation powder into a hot air circulating drying equipment, set the drying temperature to 50-80℃, dry for 20-24 hours, and dry until the moisture content of the fermentation powder is 8%-10% to obtain dried powder. Drying with hot air at 50-80℃ for 20-24 hours to achieve a humidity of 8%-10% can thoroughly remove excess moisture from materials, preventing them from becoming damp and moldy during storage and combustion, and preventing incomplete combustion that produces more tar. It can also retain heat-sensitive active ingredients such as volatile oils in medicinal materials, maintain the stability of medicinal properties, and avoid uneven combustion speed and increased impurities in flue gas caused by excessive moisture.

[0040] Optionally, the drying temperature can be set to 50℃, 60℃, 70℃, or 80℃, and the drying time can be 20h, 21h, 22h, 23h, or 24h, until the moisture content of the fermentation powder is 8%, 8.5%, 9%, 9.5%, or 10%.

[0041] S4. The dried powder is processed into filamentous material with a diameter of 0.2-0.4 mm; The material is made into filaments with a diameter of 0.2-0.4 mm. This fineness ensures uniform oxygen supply and complete combustion during incense burning, reducing tar production caused by incomplete combustion due to coarse materials. It also improves the fineness of the smoke and reduces irritation. The cross-section of this filament is circular or near-circular. Compared to the conventional rectangular cross-section, the diameter of circular / near-circular filaments (0.2-0.4 mm) is easier to control precisely, resulting in uniform thickness and minimal quality variation during mass production. Rectangular cross-sections are prone to fluctuations in aspect ratio and uneven thickness, leading to significant batch-to-batch variations in combustion and tar release. The circular cross-section significantly improves product consistency, ensuring a stable, controllable, and repeatable low-vegetable-tar effect.

[0042] In some specific embodiments, before step S4, the method further includes: adding auxiliary additives to the dried powder, wherein the amount of auxiliary additives added is 2%-3% of the total mass of the dried powder, and the auxiliary additives are made by mixing corn starch and activated carbon powder in a mass ratio of 2:1.

[0043] Adding 2%-3% is suitable for the total amount of dried powder, which can exert the auxiliary role of additives without diluting the effective ingredients of medicinal materials and affecting the moxibustion effect due to excessive addition. The 2:1 compound of corn starch and activated carbon powder can form a complementary auxiliary system, taking into account multiple functions such as adsorption and shaping. Activated carbon powder has extremely strong physical adsorption properties. Its porous structure can adsorb trace amounts of tar precursors and impurities remaining in the dried powder. During combustion, it can also adsorb some incompletely decomposed tar particles in the flue gas, further reducing the release of plant tar and reducing harmful substances in the flue gas. At the same time, it can avoid the production of odors from the combustion of impurities and improve the purity of the flue gas. As a natural binder, corn starch can enhance the binding of dried powder, making the material less prone to loosening and breakage during subsequent filament making. It can ensure that the filament material is regular in shape and uniform in diameter, which can facilitate the rolling and shaping. At the same time, corn starch burns gently and does not produce harmful substances. It can also help regulate the combustion speed, making the incense burn more steadily and the medicinal ingredients released at a uniform rate. Furthermore, all additives are natural substances with no chemical residues, aligning with the natural and safe concept of incense moxibustion. This avoids the formaldehyde and heavy metal residue problems caused by traditional additions of chemical combustion aids and binders, ensuring the safety of use for sensitive individuals. It also improves the shaping effect and combustion stability of the incense moxibustion, enhancing the user experience. Optionally, the amount of auxiliary additives added can be 2%, 2.2%, 2.4%, 2.6%, 2.8%, or 3% of the total mass of the dried powder.

[0044] S5. The filamentous material is evenly rolled into packaging paper to obtain the finished incense moxibustion product.

[0045] The roll-forming process ensures a neat finished product structure, stable combustion speed, and uniform release of medicinal components, resulting in low plant tar release, stable moxibustion efficacy, and uniform quality.

[0046] In some specific embodiments, in step S5, the roll density of the filamentous material is controlled to be 0.8-1.0 g / cm³. 3 The packaging paper is made of cotton paper or mulberry bark paper.

[0047] The density of the roll is controlled between 0.8-1.0 g / cm³. 3 It represents an excellent range for balancing combustion rate, oxygen supply efficiency, and tar formation: density below 0.8 g / cm³. 3 At times, if the material is too loose, the combustion rate is too fast, there is excessive oxygen supply, the effective components of the medicinal materials evaporate and are lost rapidly, and the duration of the moxibustion effect is short; the density is higher than 1.0 g / cm³. 3If the material is too compact, insufficient oxygen supply will result in slow and incomplete combustion, incomplete thermal decomposition of lignin and cellulose, and the generation of a large amount of viscous tar that adheres to the respiratory tract and indoor environment, causing strong irritation. This density range ensures sufficient and uniform oxygen supply during the burning of incense, complete and stable combustion, low release of plant tar, and slow and uniform release of active ingredients, prolonging the duration of the moxibustion effect and enhancing the therapeutic effect.

[0048] The packaging paper is made of cotton paper or mulberry bark paper, both of which are natural plant fiber materials. They are free of harmful substances such as chemical fluorescent agents and adhesives, and will not release harmful gases such as formaldehyde and benzene when burned. This aligns with the natural and safe concept of moxibustion and is suitable for use in enclosed spaces and by sensitive individuals. At the same time, cotton paper and mulberry bark paper are soft and flexible with moderate breathability. They can tightly wrap the fibrous materials to prevent them from scattering during transportation and use, while also ensuring normal air circulation during combustion. This helps maintain a stable combustion state and avoids the problems of poor air permeability leading to oxygen deficiency and increased tar, or excessive air permeability leading to excessively rapid combustion and loss of efficacy. This packaging further ensures the low tar, stable efficacy, and high safety characteristics of moxibustion.

[0049] In some specific embodiments, before step S5, the method further includes: applying peppermint leaf extract to the packaging paper and drying it for later use, wherein the amount of peppermint leaf extract applied is 1%-2% of the mass of the packaging paper.

[0050] Peppermint leaf extract is rich in active ingredients such as menthol and peppermint volatile oil. A 1%-2% application rate is suitable for the packaging paper quality, ensuring even adhesion and effectiveness without causing the paper to become damp, affecting rolling and burning, thus avoiding waste and quality issues. After drying, the effective components of the extract are stably adhered to the surface of the packaging paper. When the incense is burned, the packaging paper burns first, and the volatile oil in the peppermint leaf extract is rapidly released. On one hand, peppermint volatile oil has a low boiling point and strong diffusivity, which can first dilute the concentration of plant tar produced by combustion, reducing the aggregation and adhesion of tar particles, further reducing the irritation of plant tar to the respiratory tract, and relieving discomfort such as dry throat and cough. On the other hand, peppermint volatile oil emits a cool and elegant aroma, which can neutralize the slightly bitter smell of mugwort and a small amount of residual odor, making the smoke fresher and milder, with a long-lasting and elegant fragrance indoors, improving the aromatherapy environment, and enhancing user comfort and compliance. Meanwhile, peppermint leaf extract is a natural plant extract, free of chemical fragrances and preservatives, and leaves no harmful residues after burning. This meets the core requirements of natural and safe aromatherapy, ensuring it will not affect sensitive individuals. Furthermore, it can enhance the qi-regulating, mood-lifting, and cooling effects of aromatherapy, working synergistically with the peppermint in the formula to comprehensively improve the quality and user experience of the aromatherapy. Optionally, the amount of peppermint leaf extract applied may be 1%, 1.2%, 1.4%, 1.6%, 1.8%, or 2% of the packaging paper weight.

[0051] The method for preparing the low-plant tar release moxibustion of the present invention, through the whole-process collaborative design of fine raw material matching, deep microbial fermentation, gentle drying, natural additive formulation, precise filament making, controllable rolling and functional packaging, inhibits the generation of plant tar from the source, fully retains the effective components of herbs, stabilizes the combustion state and improves the quality of smoke.

[0052] First, the various medicinal herbs are pulverized to 350-500 mesh using a cell wall breaking process. This is combined with the sieving of monk fruit pulp and shell, and the low-temperature baking of leafy medicinal herbs. This process not only fully releases active substances such as flavonoids, tea polyphenols, and volatile oils, but also degrades some of the coarse fibers that are prone to producing tar in advance, reducing tar precursors, and improving the uniformity of the powder and its compatibility with subsequent processing.

[0053] Secondly, deep fermentation is carried out for no less than 100 days in a ventilated environment at 20-30℃, supplemented by a compound inoculum of yeast and lactic acid bacteria, 60%-70% humidity, and regular stirring. Through the action of microorganisms, macromolecules such as lignin and cellulose are efficiently decomposed, significantly reducing the content of tar precursors, activating medicinal components such as polysaccharides and organic acids, and avoiding the loss of medicinal efficacy caused by high-temperature carbonization.

[0054] Subsequently, a low-temperature hot air drying process at 50-80℃ is used to control the moisture content at 8%-10%. This thoroughly dehumidifies and prevents mold growth, ensuring stable combustion while maximizing the retention of heat-sensitive volatile oils, thus avoiding incomplete combustion and increased charring due to excessive moisture. After drying, a composite additive of corn starch and activated carbon powder is added. The activated carbon further adsorbs residual tar precursors and impurities, while the natural starch enhances the powder's formability, improves filament uniformity, and promotes stable combustion.

[0055] Next, the material is made into fine filaments of 0.2-0.4mm to ensure uniform oxygen supply during combustion, complete combustion, and minimal tar release.

[0056] Finally, controllable density rolls of 0.8-1.0 g / cm³ are used, and breathable and safe cotton or mulberry paper is selected. Peppermint leaf extract is thinly coated on the surface of the packaging paper to make combustion more stable, smoke more delicate, tar less attached, and aroma fresher and milder.

[0057] In summary, the entire process works in tandem, controlling tar production at each stage and increasing efficiency step by step. This achieves a comprehensive technical effect that significantly reduces the release of plant tar, ensures stable and long-lasting moxibustion effects, produces fresh and low-irritation smoke, is natural, non-toxic, and safe, and is suitable for sensitive individuals and long-term indoor use. It effectively solves the technical bottlenecks of traditional incense moxibustion, such as high tar content, poor efficacy, pungent odor, and insufficient safety.

[0084] Comparative Example 1: Traditional Pure Moxa Sticks

[0085] The raw material is only mugwort leaves. They are conventionally sun-dried, cut into sections, and ground into 80-mesh powder; there is no low-temperature baking, no fermentation, and no activated charcoal additive. They are hand-rolled using ordinary toilet paper into moxa sticks with a diameter of 18mm and a length of 200mm, following the standard manufacturing process for commercially available moxa sticks.

[0086] Comparative Example 2: Unfermented Group

[0087] The raw material composition is the same as in Example 1; the S2 fermentation step is omitted in the preparation process, and the remaining steps are the same as in Example 1.

[0088] Comparative Example 3: Lacking key tar-inhibiting components (no green tea, peppermint, or perilla)

[0089] (1) By weight, the raw materials are: 7.5 parts monk fruit, 7.5 parts loquat leaf, 7.5 parts mulberry leaf, 7.5 parts chrysanthemum, 7.5 parts licorice, and 6 parts mugwort; green tea, mint, and perilla are removed. (2) Preparation steps: exactly the same as in Example 1.

[0090] Performance comparison test

[0091] All samples have uniform specifications: 18mm in diameter, 200mm in length, and approximately 18g per piece. Placed at 1m... 3 A sealed glass test chamber was used, with a room temperature of 25℃ and a relative humidity of 55%, for natural smoldering combustion for 30 minutes. Total particulate matter (including tar) in the flue gas was collected by gravimetric method. Ten professionals conducted a blind evaluation, rating irritation (lower scores indicate less irritation) and odor comfort (higher scores indicate a fresher odor) on a scale of 1-10. The results are shown in the table below:

[0092] Comparative tests of Examples 1-4 and Comparative Examples 1-3 show that the present invention exhibits significant advantages in tar control, smoke irritation, and odor comfort. Traditional pure moxa sticks (Comparative Example 1) released up to 90.8 mg of tar in 30 minutes, exhibiting strong irritation and a poor odor, making it the worst among all samples. In contrast, the plant tar release of Examples 1-4 of the present invention was only 11.9-15.5 mg, a reduction of 83%-87% compared to traditional moxa sticks. The irritation was significantly reduced, and the odor was fresh and comfortable. This fully demonstrates that the formula and process of the present invention can significantly inhibit the formation of plant tar from the source, significantly improving safety and user experience.

[0093] Fermentation is a key step in achieving low tar levels. Under the premise of consistent formulation and other processes, the unfermented group (Comparative Example 2) released 48.7 mg of plant tar, which is 3.8 times that of Example 1. The irritation and odor comfort were also significantly worse, indicating that long-term microbial fermentation can effectively decompose lignin, cellulose and other tar precursors, and is the core technical means of reducing tar.

[0094] Green tea, peppermint, and perilla in the formula are key components for inhibiting tar and improving smoke quality. In Comparative Example 3, which lacked these three herbs, the release of plant tar increased to 39.6 mg, with increased irritation and decreased odor comfort. This confirms that green tea, peppermint, and perilla work synergistically to inhibit thermal decomposition, dilute tar concentration, and improve odor, making them an indispensable part of low-tar formulations.

[0095] Refined pretreatment of raw materials plays a positive role in optimizing the stability and quality of finished products. In Example 4, the pulverization process was simplified, and the sieving of monk fruit and low-temperature roasting of leaves were omitted. The release of plant tar was slightly higher than in Example 1, and the irritation and odor comfort were also slightly reduced. This indicates that pretreatment such as sieving of monk fruit and low-temperature roasting of leaves can refine fibers, release active ingredients, and improve combustion uniformity, thereby further optimizing the tar reduction effect and product stability.

[0096] In summary, this invention effectively solves the technical bottlenecks of traditional incense moxibustion, such as high plant tar content, strong irritation, poor odor, and insufficient safety, through a comprehensive design that integrates precise compounding of natural plants, refined pretreatment of raw materials, long-term microbial fermentation, low-temperature drying, blending of natural additives, and controllable rolling molding. It achieves a comprehensive effect of significantly reduced plant tar release, stable and long-lasting moxibustion effect, fresh and mild smoke, and natural, non-toxic and safe properties. It is especially suitable for long-term use in indoor environments, by the elderly, children, and people with respiratory sensitivities, and has good market promotion value and application prospects.

Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
