Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine external preparation technology, specifically relating to a traditional Chinese medicine external gel for unblocking meridians and relieving pain and its preparation method. Background Technology

[0002] Neck, shoulder, back and leg pain, bone and joint strain, and soft tissue swelling and pain caused by external force are common symptoms of discomfort. In the field of traditional Chinese medicine, drugs that promote blood circulation, remove blood stasis, dispel wind and dampness, and unblock meridians and relieve pain are often used for external treatment.

[0003] The existing topical analgesic ointments on the market have the following shortcomings: 1. The overall synergistic effect of the Chinese herbal composition used in existing analgesic ointments is not ideal, resulting in poor efficacy, poor duration of effect, and insufficient gentleness. Some ointments can only be used for a short period of time. 2. The Chinese herbal materials in existing ointments are only conventionally pulverized at 80-120 mesh, resulting in relatively large particle sizes. The effective ingredients have difficulty penetrating the stratum corneum, leading to low transdermal absorption efficiency and slow onset of analgesia. 3. Current ointment production generally uses high-temperature heating for mixing, such as extracting effective ingredients through decoction. However, some volatile analgesic substances are lost due to heat volatilization, significantly reducing efficacy. 4. Existing ointment preparation processes do not specify the order of ingredient addition, directly heating and mixing related components together. On the one hand, the Chinese herbal powder is prone to agglomeration and uneven dispersion, and the ointment is prone to stratification. On the other hand, high temperatures can destroy some active medicinal ingredients, resulting in poor storage stability of the finished product. Summary of the Invention

[0004] The present invention aims to provide a traditional Chinese medicine external gel for relieving pain and promoting blood circulation, and its preparation method, so as to solve the technical problems of existing analgesic ointments, such as unsatisfactory efficacy, poor transdermal absorption, loss of volatile active ingredients, and poor stability of the ointment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A topical herbal gel for relieving pain and promoting blood circulation is provided, with a total weight of 1000g, composed of the following ingredients by weight: 90-110g wintergreen oil, 20-30g turpentine oil, 18-22g menthol, 8-12g Angelica pubescens, 8-12g Ligusticum chuanxiong, 8-12g Corydalis yanhusuo, 8-12g Clematis chinensis, 8-12g Lycopodium clavatum, 4-6g cinnamon twig, 8-12g Clematis chinensis, 8-12g borneol, 4-6g safflower, 4-6g Panax notoginseng, 4-6g processed Arisaema heterophyllum, 4-6g Geranium wilfordii, 4-6g Corydalis yanhusuo, 4-6g rhubarb, 4-6g Zanthoxylum bungeanum, 4-6g Angelica dahurica, 4-6g Angelica sinensis, 4-6g Luffa cylindrica, and the remainder is medical-grade white petrolatum.

[0006] Preferably, the total weight of this traditional Chinese medicine external gel for unblocking meridians and relieving pain is 1000g, composed of the following raw materials by weight: 100g wintergreen oil, 25g turpentine oil, 20g menthol, 10g Angelica pubescens, 10g Ligusticum chuanxiong, 10g Corydalis yanhusuo, 10g Clematis chinensis, 10g Lycopodium clavatum, 5g cinnamon twig, 10g Clematis armandii, 10g borneol, 5g safflower, 5g Panax notoginseng, 5g processed Arisaema heterophyllum, 5g Geranium wilfordii, 5g Corydalis yanhusuo, 5g rhubarb, 5g Zanthoxylum bungeanum, 5g Angelica dahurica, 5g Angelica sinensis, 5g Luffa cylindrica, and the remainder is medical white petrolatum.

[0007] This invention also provides a method for preparing the aforementioned traditional Chinese medicine external gel for unblocking meridians and relieving pain, comprising the following steps: S1: Weigh each of the Chinese herbal raw materials in claim 1 according to the corresponding weight parts, and pulverize the following ingredients separately: Angelica pubescens, Ligusticum chuanxiong, Corydalis yanhusuo, Clematis chinensis, Lycopodium clavatum, Cinnamomum cassia, Clematis armandii, Carthamus tinctorius, Panax notoginseng, processed Arisaema heterophyllum, Geranium wilfordii, Corydalis yanhusuo, Rheum palmatum, Zanthoxylum bungeanum, Angelica dahurica, Angelica sinensis, and Luffa cylindrica. Pass them through a 280-320 mesh sieve and mix them evenly to obtain ultrafine powder of Chinese herbal medicine. S2: Dissolve the menthol and borneol weighed according to the corresponding weight parts in the corresponding weight parts of wintergreen oil and turpentine oil, then add the Chinese herbal ultrafine powder and stir evenly to obtain the medicinal oil mixture. S3. Melt the medical-grade white petrolatum by heating it in a water bath; S4. Add the molten medical white petrolatum to the medicinal oil mixture, adjust the total weight to 1000g, dispense and cool to obtain the finished gel.

[0008] Preferably, the water bath heating temperature in step S3 is controlled at 40-50°C.

[0009] Preferably, step S2 is performed by mixing and stirring at room temperature.

[0010] Preferably, in step S1, the corresponding raw materials are crushed and mixed, then passed through a 300-mesh sieve and mixed evenly to obtain ultrafine powder of traditional Chinese medicine.

[0011] The pharmacology of this traditional Chinese medicine external gel for unblocking meridians and relieving pain is as follows: (1) This formula is a combination of Chinese and Western medicine for external use. The treatment principle is "warming the meridians and promoting blood circulation, relieving pain, and dispelling wind and dampness". The principal, assistant, adjuvant and guide ingredients are as follows: The principal ingredient is wintergreen oil. Wintergreen oil mainly contains methyl salicylate. When used externally, it has significant anti-inflammatory and analgesic effects. It can penetrate deep into the skin and directly inhibit local inflammatory response and pain transmission. The assistant ingredients include turpentine oil, menthol, chuanxiong, and yuanhu. Turpentine oil is an external stimulant that promotes local blood circulation, enhances the analgesic effect of wintergreen oil, and warms the meridians and promotes blood circulation. Menthol is cooling and antipruritic, anti-inflammatory and analgesic, promotes transdermal absorption, opens the skin channels, and helps the principal ingredient and other ingredients penetrate into the body. Chuanxiong promotes blood circulation, dispels wind and relieves pain, and promotes the flow of qi and blood in the meridians. Yuanhu and yanhusuo promote blood circulation, dispel wind and relieve pain, and can enhance the central analgesic effect. Synergistic and adjuvant herbs include Angelica pubescens, Clematis chinensis, Lycopodium clavatum, Clematis armandii, Carthamus tinctorius, Panax notoginseng, processed Arisaema heterophyllum, and Geranium wilfordii. Angelica pubescens dispels wind and dampness, relieves pain, and is effective in treating lower limb muscle and joint pain; Clematis chinensis dispels wind and dampness, relaxes muscles and promotes blood circulation, disperses blood stasis and reduces swelling; Lycopodium clavatum dispels wind and dampness, relaxes muscles and promotes blood circulation, and is specifically used to treat muscle spasms and difficulty in flexion and extension; Clematis armandii dispels wind and dampness, unblocks meridians, promotes blood circulation, removes blood stasis and reduces swelling; Carthamus tinctorius promotes blood circulation, unblocks meridians, disperses blood stasis and relieves pain, and is effective in unblocking meridians; Panax notoginseng disperses blood stasis, stops bleeding, reduces swelling and relieves pain; processed Arisaema heterophyllum reduces swelling, disperses nodules and relieves pain, and is effective in treating swelling and pain caused by phlegm and dampness obstruction; Geranium wilfordii dispels wind and dampness, unblocks meridians, and can also promote blood circulation and relieve pain, and is effective for rheumatic pain and traumatic injuries; the guiding herbs include Cinnamomum cassia and Borneol. Cinnamomum cassia warms and unblocks meridians, and assists Yang and transforms Qi; Borneol is aromatic and penetrating, opens orifices and penetrates bones, and increases skin permeability.

[0012] (2) The whole formula consists of a three-layer analgesic system: the combination of wintergreen oil, menthol and borneol is used to produce a cooling sensation and to relieve pain quickly on the surface; the combination of chuanxiong, yuanhu, safflower and sanqi is used to improve microcirculation and produce local anesthetic-like analgesia and blood-activating analgesia effects; the combination of kougucao, shenjincao, weilingxian and duhuo penetrates deep into the muscles and bones, dispels wind and dampness, and produces deep meridian-clearing and pain-relieving effects, and where there is free flow, there is no pain.

[0013] (3) The transdermal absorption mechanism of this formula is as follows: Menthol, borneol and turpentine are all natural transdermal permeability enhancers, which triple promote penetration. Wintergreen oil has good skin permeability. Multiple volatile oils work together to open the skin barrier. The external gel matrix prolongs the drug residence time and allows for sustained drug delivery. (4) This formula is mainly warming and unblocking, and uses both cold and warm herbs. Cinnamon twig, Sichuan lovage rhizome, safflower, turpentine oil and wintergreen oil are warming herbs, which have the effect of warming the meridians and unblocking the blood vessels; menthol and borneol are cooling herbs, which have the effect of cooling and relieving pain and counteracting the dryness of warming herbs; most of the other wind-dampness dispelling herbs are neutral to warm, which have the effect of unblocking the meridians and relieving pain.

[0014] This formula is suitable for joint pain and swelling caused by wind-cold-dampness syndrome and blood stasis; muscle soreness and strain; sprains and bruises, swelling and pain due to blood stasis; neck, shoulder, waist and leg pain, and numbness of muscles and bones. Precautions: Do not use on broken skin; use with caution in pregnant women (contains safflower, Panax notoginseng and other blood-activating herbs); those with allergies should test on a small area first.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: 1. Based on the above pharmacological analysis, the external herbal gel for relieving pain and promoting blood circulation is scientifically formulated, with good overall synergistic effect of each component, resulting in good efficacy, long-lasting effects, and a mild and non-irritating overall effect, suitable for long-term use; 2. By pulverizing the relevant components into 300-mesh ultrafine powder, the specific surface area is significantly increased compared to conventional coarse powder, allowing the effective ingredients to penetrate the stratum corneum of the skin and enter the subcutaneous tissue more quickly; at the same time, components such as wintergreen oil and turpentine oil are excellent transdermal penetration enhancers, which can dilate local capillaries, further promote drug absorption, and achieve rapid analgesia. 3. This ointment adopts a low-temperature preparation process, with the highest temperature throughout the production process not exceeding 50°C, and volatile components such as menthol and borneol are pre-dissolved in wintergreen oil and turpentine oil at room temperature, avoiding volatilization loss caused by high-temperature heating. The retention rate of volatile effective ingredients can reach more than 95%, significantly higher than the 60-70% of traditional high-temperature processes, resulting in a stronger and longer-lasting analgesic effect in the finished product. 4. In preparing this ointment, the powder is first dispersed in the oil phase, and then molten petrolatum is added last. This avoids the problem of agglomeration caused by direct contact between the high-temperature petrolatum and the powder. The powder is evenly dispersed in the matrix, the ointment is fine and free of particles, and the ointment has good storage stability. 5. Processed Arisaema heterophyllum is used in the formula instead of raw Arisaema heterophyllum. After processing, its toxicity is significantly reduced, making it safer for external use. The entire formula is rationally combined, using three methods to dispel wind and dampness, promote blood circulation and remove blood stasis, and warm the meridians and unblock collaterals. It has a good relieving effect on various pain symptoms such as muscle strain, joint pain, sprains and bruises, and neck, shoulder, waist and leg pain. Detailed Implementation

[0032] Effect verification test A comparative test was conducted between the product prepared in Example 2 and a commercially available similar analgesic ointment (Compound Arisaema Analgesic Ointment): Subject selection: Twenty volunteers diagnosed with lumbar muscle strain, aged 25-55 years, were selected. All participants presented with varying degrees of lower back pain, with comparable pain levels on both sides of the lower back. A self-controlled method was used. The left side of the participants' lower back was treated with the gel of Example 2 of this invention, while the right side was treated with a commercially available control analgesic ointment (Compound Arisaema Analgesic Ointment). The application amount for both was 0.5g / 100cm². 2 .

[0033] Evaluation method: Pain level was assessed using the Visual Analogue Scale (VAS) at 30 minutes, 1 hour, and 2 hours after application, with 0 indicating no pain and 10 indicating the most severe pain. The results are shown in Table 1. Table 1 - Statistical table of results of the comparative test on analgesic effects of the two groups

[0034] Note: VAS is the Visual Analogue Scale. 0 points indicates no pain and 10 points indicates the most severe pain. The greater the decrease in score, the better the analgesic effect.

[0035] Table 1 shows that 30 minutes after application, the VAS score of the invention group decreased by an average of 2.8 points, while that of the control group decreased by an average of 1.1 points. Two hours after application, 17 subjects in the invention group experienced significant pain relief, with an average VAS score decrease of 4.6 points, while only 8 subjects in the control group experienced pain relief, with an average VAS score decrease of 2.3 points. The experimental results indicate that the product of this invention has a faster onset of pain relief, a stronger effect, and is significantly more effective than commercially available products. No allergic reactions such as skin redness, swelling, or itching occurred during the experiment, demonstrating the good safety profile of the product.
