Description

Technical Field

[0001] This invention relates to the field of Tibetan medicine external preparations, specifically to a Tibetan medicine Darqiang external ointment and its preparation method. Background Technology

[0002] Tibetan medicine has a long history of application in skin care and the treatment of skin discomfort. Some traditional prescriptions are used internally in the form of powders and pills, exerting their effects through holistic regulation. With the development of topical preparations, formulating traditional Tibetan medicine prescriptions with skin care value into ointments, creams, and other topical preparations has become an important direction for related product development. Topical ointments can act directly on the skin surface, are relatively easy to use, and facilitate local application and quantitative dosage, thus demonstrating good applicability in applications such as skin repair, skin cleansing and care, and relief of local discomfort.

[0003] Darqiang is a traditional Tibetan medicine formula, currently used primarily in the form of oral powders. For this type of traditional internal medicine, directly applying it to the skin in its original powder form often results in problems such as noticeable powder particles, insufficient adhesion, uneven local application, and poor ease of use, failing to meet the requirements of modern topical preparations for uniformity, fineness, formability, and stability. On the other hand, while some existing topical ointments use an oil-based matrix mixed with medicinal powders, the preparation process often lacks specific design for the purification requirements of different medicinal materials, moisture control, powder particle size control, and the matching relationship with the matrix. This can easily lead to the formation of clumps, coarse particles, oil separation, layering, or batch-to-batch inconsistencies, thus affecting the quality of the finished product and its actual efficacy.

[0004] Especially for Tibetan medicine formulations containing medicinal materials from multiple sources with different properties, if the materials are not pre-treated for compatibility during the external application process, or if the pulverization and sieving conditions, matrix melting state, powder addition temperature, stirring time, and filling conditions are not coordinated and controlled, it is difficult to obtain a uniform, stable, and easily quality-controlled external ointment product. Therefore, it is still necessary to provide a Tibetan medicine Darqiang external ointment and its preparation method to solve the problems of uneven powder dispersion, insufficient ointment stability, inconsistent finished product state, and inconvenience of use in the external application process of traditional Darqiang formulations in the existing technology. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a Tibetan medicine Darqiang external ointment and its preparation method to solve the technical problems existing in the prior art.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A Tibetan medicine external ointment, Darqiang, comprises: a mixture of fine powdered medicinal materials and medical petroleum jelly, wherein the mixture of fine powdered medicinal materials is dispersed in the medical petroleum jelly to form an ointment; The fine powder of the medicinal materials is made from sea buckthorn, alkali flower, rhododendron and artemisia.

[0007] Preferably, the medicinal material powder is obtained by purifying and pulverizing sea buckthorn, alkali flower, rhododendron and artemisia, and then passing it through a 160-mesh sieve.

[0008] Preferably, the sea buckthorn is the fruit, the rhododendron is the dried flower and tender branches and leaves, and the artemisia is the dried above-ground part.

[0009] Preferably, the alkali-processing flower is purified, stir-fried, dried, and pulverized to form the alkali-processing flower fine powder in the mixed fine powder of medicinal materials.

[0010] Preferably, the weight parts of sea buckthorn, alkali-producing flower, rhododendron, artemisia capillaris and medical petroleum jelly are 50 parts, 100 parts, 5 parts, 5 parts and 800 parts, respectively.

[0011] A method for preparing a Tibetan medicine external ointment, Darqiang, includes the following steps: S1: The sea buckthorn, alkali flower, rhododendron and wormwood are cleaned separately. The alkali flower is stir-fried and dried, then mixed with the other medicinal materials, pulverized and sieved to obtain a fine powder of mixed medicinal materials. S2: Heat medical petroleum jelly to a molten state; S3: Under stirring conditions, the fine powder of medicinal materials is added to molten medical petroleum jelly and mixed evenly to obtain an ointment; S4: After cooling the ointment, it is filled into containers to obtain Tibetan medicine Darqiang external ointment.

[0012] Preferably, the cleaning process of the sea buckthorn involves removing impurities, fruit stalks, and moldy fruits; the cleaning process of the rhododendron involves removing impurities, old stems, and residual branches; the cleaning process of the artemisia capillaris involves removing impurities and then cutting it into sections; and the cleaning process of the alkali flower involves removing impurities.

[0013] Preferably, the alkali-making flowers are cleaned and then stir-fried to remove moisture; Sea buckthorn, alkali-resistant flower, rhododendron and artemisia are cleaned, mixed and pulverized, and then passed through a 160-mesh sieve to obtain a fine powder of medicinal materials.

[0014] Preferably, the medical petroleum jelly is heated to 60℃~70℃ to melt, and then mixed with fine powder of medicinal materials at 55℃~60℃ and stirred for 5~10 minutes.

[0015] Preferably, the paste is cooled to 40℃~45℃ before being filled into glass bottles, and then cooled and set after filling.

[0016] In summary, the present invention has the following main beneficial effects: By subjecting sea buckthorn, alkali-processing flower, rhododendron, and artemisia to targeted purification treatments, and by frying and drying alkali-processing flower before adding it to the ointment, and then pulverizing it together with the other medicinal materials and passing it through a 160-mesh sieve, the resulting fine powder mixture achieves a more uniform particle size, easier control of moisture content, and more even dispersion in the ointment. Simultaneously, by preparing the ointment using medical petroleum jelly at 60℃~70℃ and adding powder and stirring at 55℃~60℃, the probability of lumps, dry powder, and significant agglomeration is reduced, and the uniformity and stability of the ointment are improved. This results in a topical ointment that is more suitable for use as a skin preparation in terms of texture, appearance, and application.

[0017] By formulating Darqiang's formulation into a topical ointment and using medical-grade petroleum jelly as the ointment base, the medicinal ingredients can be applied directly to the affected skin via external application, shortening the application path and enhancing ease of use. At the same time, by stably dispersing the mixed fine powder of medicinal materials in medical-grade petroleum jelly, the formulation achieves continuous film-forming ability, good adhesion and spreadability, making it easier to apply, measure, and perform local care, thus improving the problem of traditional powders being inconvenient to apply directly in external scenarios. Attached Figure Description

[0018] Figure 1 This is a flowchart of the method of the present invention. Detailed Implementation

[0019] 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.

[0020] Example 1 To clarify the technical solution, preparation process, and correspondence between the Tibetan medicine Darqiang external ointment described in this application and the claims, further explanation is provided below in conjunction with specific embodiments. This application employs a preparation route that directly incorporates finely mixed medicinal powders into the ointment, without solvent extraction, emulsifiers, preservatives, fragrances, or other excipients. The resulting product is made from sea buckthorn, alkali-producing flowers, rhododendron, and Artemisia capillaris with medical petrolatum.

[0021] The herbal powder mixture in this application refers to a mixture of sea buckthorn, alkali-processed flower, rhododendron, and artemisia tail grass, which have been purified separately, with the alkali-processed flower further processed by roasting and drying, and then pulverized together with the other herbs and sieved. The ointment mixture in this application refers to a homogeneous semi-solid system formed by adding the herbal powder mixture to molten medical petroleum jelly and stirring.

[0022] refer to Figure 1 A Tibetan medicine topical ointment, Darqiang, comprising: It is made from the following raw materials: 50g of sea buckthorn, 100g of alkali-producing flower, 5g of rhododendron, 5g of Artemisia capillaris, and 800g of medical petroleum jelly. The raw material composition and main process parameters are shown in Table 1.

[0023] Table 1 Raw material composition and main process parameters As shown in Table 1, this embodiment clearly defines the raw material composition and main process parameters. The ratio of medicinal materials, the sieving conditions of the mixed fine powder of medicinal materials, the melting temperature of medical petroleum jelly, the powder addition and stirring temperature, the stirring time, the filling temperature, and the coordination between the filling containers together constitute the basic preparation conditions of the Tibetan medicine Darqiang external ointment of this application.

[0024] Raw material processing: Sea buckthorn berries are selected as raw material. Impurities, fruit stalks, and moldy berries are removed, leaving only the healthy berries for later use. This process is to prevent impurities and abnormal raw materials from affecting the uniformity of subsequent grinding and the appearance of the finished product.

[0025] Take the raw material for alkali-making flakes, remove visible impurities, and then stir-fry. During stir-frying, continuously turn the flakes to ensure even heating, and continue stir-frying until the raw material no longer feels noticeably damp and does not form moist clumps when rubbed between the fingers. After stir-frying, allow it to cool naturally and then dry it for later use. This step is to reduce residual moisture in the alkali-making flakes, lowering the possibility of localized clumping during subsequent processing into ointments.

[0026] Select dried flowers and tender leaves of Rhododendron simsii, remove impurities, old stems and damaged branches, and set aside.

[0027] Select the dried aerial parts of Artemisia capillaris, remove impurities, and cut into sections for later use. Cutting into sections makes it easier to grind with other medicinal materials.

[0028] Table 2 Processing requirements for each medicinal material As shown in Table 2, this embodiment sets corresponding cleaning and pretreatment requirements for different medicinal materials based on their raw material properties. Among them, the alkali flower is further stir-fried, cooled and dried after cleaning, while sea buckthorn, rhododendron and artemisia are cleaned according to their raw material state, thus providing the prerequisite for subsequent co-pulverization and uniform addition to the paste.

[0029] Preparation of fine powder from mixed medicinal materials: The sea buckthorn, alkali-producing flowers, rhododendron, and artemisia are then fed into a pulverizing device for further grinding. After grinding, the mixture is sieved through a 160-mesh sieve. The material remaining on the sieve is returned for further grinding until all the material passes through the 160-mesh sieve, resulting in a fine powder of the medicinal herbs.

[0030] This embodiment uses a method of co-pulverizing and uniformly sieving to prepare a mixed fine powder of medicinal materials, rather than pulverizing the four medicinal materials separately and then blending them. By co-pulverizing and uniformly controlling the sieving conditions, the particle size of the resulting mixed fine powder of medicinal materials is kept consistent, which facilitates its uniform dispersion in medical petroleum jelly.

[0031] ointment preparation: Add 800g of medical-grade petroleum jelly to a stainless steel heating container and heat to 60℃~70℃ until the petroleum jelly is completely melted. Melting is complete when there are no obvious solid lumps in the container and the overall flow is uniform and dynamic.

[0032] After the medical petroleum jelly has completely melted, maintain the system temperature between 55℃ and 60℃. While maintaining this temperature range, add the finely powdered medicinal materials in portions to the molten medical petroleum jelly, stirring continuously. After each addition, wait until the added portion is fully wetted and dispersed by the medical petroleum jelly before adding the next portion. After all the finely powdered medicinal materials have been added, continue stirring for 5–10 minutes to obtain the ointment.

[0033] The criteria for judging uniform mixing of the paste are as follows: the paste has a consistent overall color, with no visible lumps, dry powder, or obvious agglomerates; a small amount of paste applied to a clean glass plate shows no obvious coarse particle marks; and samples taken from the upper, middle, and lower layers of the same container show no significant differences in color and consistency. Once these conditions are met, heating and stirring should be stopped.

[0034] Table 3 Key Control Points in the Ointment Preparation Process As shown in Table 3, this embodiment has clearly defined the key control points in the ointment preparation process. By controlling the melting state of medical petrolatum, powder addition temperature, powder addition method, stirring time, and ointment uniformity, the fine powder of medicinal materials can form a uniform and stable ointment in medical petrolatum.

[0035] Filling and shaping: The resulting paste is cooled to 40℃~45℃ before being filled into glass bottles. After filling, the bottles are sealed and allowed to continue cooling and setting. Cooling and setting is considered complete when there is no free oil layer on the surface of the contents and the paste inside the bottle no longer flows.

[0036] Finished product status: The finished product obtained in this embodiment is a yellow to yellowish-brown semi-solid state. The paste is continuous and uniform, without any pungent odor. When applied, it forms a continuous paste film with adhesive properties, and no obvious oil separation or layering was observed. For ease of explanation, the state of the finished product is summarized in Table 4.

[0037] Table 4 Finished Product Status Record As shown in Table 4, the Tibetan medicine Darqiang external ointment prepared according to the raw material composition and preparation process of this embodiment is stable in terms of appearance, state, texture, odor, spreading state, adhesion, oil separation and layering, indicating that the process of this application can obtain a finished external ointment with uniform state.

[0038] Example 2 Using the same raw material composition and preparation steps as in Example 1, another batch of Tibetan medicine Darqiang external ointment was prepared. The amounts of each raw material remained the same: 50g of sea buckthorn, 100g of alkali-processed flower, 5g of rhododendron, 5g of Artemisia capillaris, and 800g of medical petroleum jelly. The difference was that the finely mixed powder of all the medicinal materials was added to the molten medical petroleum jelly in three batches, with continuous stirring after each addition. The next addition was only made after the previous batch of finely mixed powder had been completely dispersed. The remaining steps were the same as in Example 1.

[0039] The finished product obtained in this embodiment is consistent with that in Example 1, both being uniform semi-solid pastes with no obvious lumps, oil separation, or stratification. This indicates that the Tibetan medicine Darqiang external ointment that meets the requirements can be reproduced by using the fractional powder addition method within the raw material composition, sieving conditions, melting temperature, powder addition temperature, stirring time, and filling temperature specified in this application.

[0040] Example of sample retention and observation: The finished product obtained in Example 1 was filled, cooled, and set, then left to stand at 25°C for 24 hours for observation. Observation items included whether a free oil layer appeared on the surface, whether the color was consistent throughout the bottle, whether visible layering was present, and whether there were obvious particle drag marks during sample spreading. The observation results are shown in Table 5.

[0041] Table 5 Sample retention observation record As shown in Table 5, after the preparation of the finished product obtained in Example 1 and after standing at 25°C for 24 hours, no surface oil layer, color inconsistency, layering and obvious particle drag marks were observed. This indicates that the finished product can maintain good appearance consistency and state stability under short-term standing conditions.

[0042] Detection Example: Samples of the Tibetan medicine Darqiang external ointment prepared according to Example 1 were tested for heavy metals and microorganisms. The submitted sample name was Skin Repair Acne Removal and Health Care Ointment, report number was JCJC-HZ202605000202, production date was May 9, 2026, batch number was 20260507, specification quantity was 50g / box × 3, and testing period was from May 9, 2026 to May 15, 2026.
