Abstract
Description
Technical Field
[0001] The invention relates to the technical field of traditional Chinese medicine preparations, in particular to Qianjin nourishing powder for traditional Chinese medicine foot bath. Background Art
[0002] Foot bath with Chinese medicine is a traditional health care method. By using a specific Chinese medicine formula and the heat of hot water, the Chinese medicine ingredients are helped to penetrate into the skin, be absorbed by the capillaries of the feet, and enter the blood circulation system, thereby achieving the effect of improving physical fitness, conditioning the body, and treating diseases.
[0003] Some existing Chinese medicine foot baths have a single ingredient. For example, some foot baths focus on removing rheumatism and may only contain rheumatism-removing drugs such as Clematis chinensis and Angelica dahurica. For patients with both rheumatic symptoms and liver and kidney deficiency, this single-ingredient medicine cannot comprehensively improve their physical condition. Some other medicines are mainly for promoting blood circulation, and the ingredients are concentrated on blood-activating and blood-stasis-removing drugs such as safflower and Chuanxiong, lacking comprehensive conditioning effects on other body systems. Summary of the invention
[0004] In view of the deficiencies in the prior art, the present invention provides a kind of Qianjin nourishing powder for Chinese medicine foot bath.
[0005] To achieve the above purpose, the present invention provides the following technical scheme: Qianjin Nourishing Powder for traditional Chinese medicine foot bath, comprising liver and kidney strengthening and tendon and bone strengthening components, spleen and blood nourishing components and wind-dispelling, dampness-removing and collateral-dredging components, which are ground into fine particles, and all the fine particles are mixed and dissolved in warm water for foot bathing; Among them, the liver and kidney strengthening and tendon and bone strengthening ingredients include 60 grams of dog spine, 60 grams of Achyranthes bidentata, 60 grams of Rehmannia glutinosa, 60 grams of mistletoe, 60 grams of Qiannianjian, 60 grams of Dipsacus asper, 60 grams of Eucommia ulmoides, and 60 grams of Epimedium; Among them, the spleen-strengthening and blood-nourishing ingredients include 40 grams of Chinese yam, 40 grams of Cornus officinalis, and 30 grams of Chinese angelica; Among them, the wind-dispelling, dampness-removing and meridian-dredging ingredients include 30g of Radix Angelicae Pubescentis, 30g of Radix Polygoni Multiflori, 30g of Caulis Spatholobi, 30g of Caulis Sinomenii, and 30g of Cortex Moutan; Divide into 20 packages with a specification of 30 grams per package and then package.
[0006] Preferably, after selecting the medicinal materials, they are inspected to remove impurities, dirt and non-medicinal parts, and the medicinal materials are cut into small pieces or segments to facilitate subsequent grinding. The medicinal materials are cut into small pieces of about 1-2 cm and placed in a grinding device for further grinding.
[0007] Preferably, sieves of different mesh sizes are prepared, such as 80 mesh, 100 mesh and 120 mesh. The higher the mesh size, the smaller the aperture of the sieve, and the finer the powder passing through the sieve; During the grinding process, a sieve is used to screen out fine particles that meet the requirements, and coarse particles that do not meet the requirements are ground again.
[0008] Preferably, the processed medicinal materials are put into the grinding device in small amounts and multiple times, and the amount of medicinal materials put in each time should not exceed one-third of the capacity of the grinding bowl, so that there is enough space for grinding. During the grinding process, the power of the grinding device can be gradually increased to crush larger medicinal material blocks, and then the grinding speed is gradually increased to turn the medicinal materials into fine powder; After each grinding, the coarse particles are screened through a sieve and ground again until a sufficient amount of fine particles is obtained.
[0009] Preferably, the other medicinal materials are added in the order of the prescription. Each time a medicinal material is added, it should be thoroughly stirred with a clean spoon or stirring rod. When stirring, stir from the bottom of the container upwards to ensure that the different medicinal materials can be evenly mixed at all levels.
[0010] Preferably, when using the nourishing powder, choose a foot bath basin made of wood or ceramic. The height of the foot bath basin should be appropriate to ensure that the ankle joints are covered when soaking the feet. The depth should be 20-30 cm, so that the feet can be fully immersed in the medicine to make the medicine work better.
[0011] Preferably, add an appropriate amount of water into the foot bath, and control the water temperature at 40-45°C; Use a water thermometer to accurately measure the water temperature. If the water temperature is too high, it will burn the skin and destroy the effective ingredients of traditional Chinese medicine. If the water temperature is too low, it will be detrimental to the absorption of the drug ingredients and the promotion of blood circulation. During the foot soaking process, if the water temperature drops, you can add appropriate amount of hot water to maintain the water temperature.
[0012] Preferably, each foot soak should be kept for 20-30 minutes, so that the foot skin can fully absorb the active ingredients of the medicine, and it can also effectively promote blood circulation in the feet and the whole body; If the foot soaking time is too short, the medicine may not have time to be fully absorbed; if the time is too long, it may cause the skin of the feet to be over-soaked, causing the skin to wrinkle and turn pale, and even cause dizziness, palpitations and other uncomfortable symptoms due to excessive sweating.
[0013] Preferably, during the foot soaking process, the feet can be properly massaged; Use the thumb and index finger of both hands to gently pinch the toes, rub from the toe tip to the toe base, and massage each toe for 1-2 minutes; Then, rub the soles of your feet with the palms of your hands, from the heels to the toes, focusing on massaging the Yongquan acupoint; through massage, the blood circulation of the feet is further promoted, which helps the medicine to be better absorbed and enhances the effect of foot soaking.
[0014] Preferably, since the blood circulation of the feet is accelerated after foot soaking, the pores are in an open state, so you should pay attention to keeping warm and wear warm and comfortable socks to avoid cold feet. If you do not pay attention to keeping warm, cold and dampness will take the opportunity to invade the feet, affecting the effect of foot soaking and even aggravating the original symptoms.

[0026] After selecting the medicinal materials, check them to remove impurities, dirt and non-medicinal parts, cut them into small pieces or segments to facilitate later grinding, cut the medicinal materials into small pieces of about 1-2 cm and put them into the grinding equipment for grinding.
[0027] Prepare sieves of different mesh sizes, such as 80 mesh, 100 mesh, and 120 mesh. The higher the mesh size, the smaller the aperture of the sieve, and the finer the powder that passes through the sieve; During the grinding process, a sieve is used to screen out fine particles that meet the requirements, and coarse particles that do not meet the requirements are ground again.
[0028] The processed medicinal materials are put into the grinding equipment in small amounts and multiple times. The amount of medicinal materials put in each time should not exceed one-third of the capacity of the grinding bowl, so that there is enough space for grinding. During the grinding process, the power of the grinding equipment can be gradually increased to crush the larger medicinal material blocks, and then the grinding speed can be gradually increased to turn the medicinal materials into fine powder. After each grinding, the coarse particles are screened through a sieve and ground again until a sufficient amount of fine particles is obtained.

[0031] Add an appropriate amount of water into the foot bath and control the water temperature at 40-45℃; Use a water thermometer to accurately measure the water temperature. If the water temperature is too high, it will burn the skin and destroy the effective ingredients of traditional Chinese medicine. If the water temperature is too low, it will be detrimental to the absorption of the drug ingredients and the promotion of blood circulation. During the foot soaking process, if the water temperature drops, you can add appropriate amount of hot water to maintain the water temperature.
[0032] Keep your foot bath time at 20-30 minutes each time, so that the foot skin can fully absorb the active ingredients of the medicine, and it can also effectively promote blood circulation in the feet and the whole body; If the foot soaking time is too short, the medicine may not have time to be fully absorbed; if the time is too long, it may cause the skin of the feet to be over-soaked, causing the skin to wrinkle and turn pale, and even cause dizziness, palpitations and other uncomfortable symptoms due to excessive sweating.
[0033] During the foot soaking process, you can massage your feet appropriately; Use the thumb and index finger of both hands to gently pinch the toes, rub from the toe tip to the toe base, and massage each toe for 1-2 minutes; Then, rub the soles of your feet with the palms of your hands, from the heels to the toes, focusing on massaging the Yongquan, Mianyang, Kunlun, and Chengshan points; through massage, you can further promote blood circulation in the feet, help better absorption of medicines, and enhance the effect of foot soaking.
[0034] Since the blood circulation in the feet is accelerated and the pores are open after foot soaking, you should pay attention to keeping warm and wear warm and comfortable socks to avoid cold feet. If you do not pay attention to keeping warm, cold and dampness will take the opportunity to invade the feet, affecting the effect of foot soaking and even aggravating the original symptoms.

2. The Qianjin Nourishing Powder for foot soaking according to claim 1, characterized in that: After selecting the medicinal materials, the processing characteristics of the medicinal materials are checked. Some of the processing methods are as follows: As the "Yellow Emperor's Internal Classic" said: "The kidney governs the bones." Salt is salty and enters the kidney meridian, which can lead the medicine into the kidney. Therefore, the medicinal materials processed with salt can enhance their function of nourishing the liver and kidney and strengthening the tendons and bones. For example, add salt water to dog spine and mix well and steam it. Achyranthes bidentata, Dipsacus asper, and Eucommia ulmoides are mixed well with salt water and stir-fried. Rehmannia glutinosa is made by nine steaming and nine drying. Epimedium brevicornum is made by adding mutton fat and heating to melt it, and then stir-frying it. Earth is in the center and mainly enters the spleen meridian. Therefore, spleen-strengthening medicinal materials are mostly processed with earth powder. For example, angelica is fried until it is covered with fine earth powder, and the earth powder is sieved out. Wine is sweet and spicy in nature, and can promote blood circulation and dredge the meridians, dispel wind and dampness. Rice wine is mixed with Millettia reticulata and Paeonia suffruticosa, and then fried to dryness to enhance its effect of dispelling wind and dampness, promoting blood circulation and dredge the meridians. Cut the medicinal materials into small pieces or segments to facilitate later grinding. Cut the medicinal materials into small pieces of about 1-2 cm and put them into the grinding equipment for grinding.
3. The Qianjin Nourishing Powder for foot soaking according to claim 1, characterized in that: Prepare sieves of different mesh sizes, such as 80 mesh, 100 mesh, and 120 mesh. The higher the mesh size, the smaller the aperture of the sieve, and the finer the powder that passes through the sieve; According to the application site, method and properties of the medicinal materials of Qianjin Ziyang Powder, the conventional powder size standard of this powder is determined to be all through the No. 5 sieve (80 meshes) and contain no less than 95% that can pass through the No. 6 sieve (100 meshes), that is, the powder grade is fine powder; special medicinal materials including cooked rehmannia, cornus and yam are rich in starch and polysaccharides. If the powder is crushed too finely, starch gelatinization is easily produced when brewing with hot water, blocking the capillary channels on the surface of the medicinal materials, making it difficult for the effective ingredients to dissolve and affecting the efficacy: Therefore, the powder size standard of these three medicinal materials is determined to be all through the No. 4 sieve (65 meshes), but mixed with no more than 60% of the powder that can pass through the No. 5 sieve (80 meshes), that is, the powder grade is medium powder. During the grinding process, the fine particles that meet the requirements are screened out with a sieve, and the coarse particles that do not meet the requirements are ground again.
