CHINESE MEDICINE GRANULE FOR INVIGORATING SPLEEN, REMOVING OBSTRUCTION IN COLLATERALS AND DETOXIFICATION
A Chinese medicine granule for invigorating the spleen, removing obstruction in collaterals and detoxification. The Chinese medicine granule comprising: 20-40 g of astragalus membranaceus, 10-25 g of tangshen, 10-20 g of bighead astractylodes rhizome, 1-10 g of raw licorice, 5-15 g of dry pinellia ternate, 5-15 g of Pericarpium citri reticulatae, 5-15 g of fructus amomi, 7-18 g of nutgrass galingale rhizome, 20-40 g of tuber fleeceflower stem, 1-3 centipedes, 10-20 g of earthworm, 10-20 g of radix clematidis, 5-15 g of corydalis tuber, 20-40 g of red sage root, 5-15 g of radix bupleuri, 20-40 g of indigowoad root, 20-40 g of coix seed, and 5-15 g of indigo naturalis. The Chinese medicine granule is prepared by the following steps: weighing each raw material according to the formula; and preparing a granule dosage form. The Chinese medicine granule has a simple formula, is easy to use, and achieves efficacy quickly. The Chinese medicine granule can be effectively used in the treatment of both herpes zoster and complications thereof, such as postherpetic neuralgia, bedsores, and ecthyma, so as to significantly reduce distress in a patient.
A Chinese medicine granule for boosting vital energy and managing cachexia. The Chinese medicine granule is used for the treatment of symptoms such as rapid emaciation and the like in advanced cancer. Raw materials for the Chinese medicine granule are: 110-130 g of astragalus membranaceus, 20-40 g of ginseng, 50-70 g of dogwood, 20-40 g of trogopterus dung, 5-15 g of clove, and 5-15 g of turmeric root tuber. The Chinese medicine granule is prepared by the following steps: weighing, pulverizing and mixing the raw materials; adding water to immerse the materials, boiling, decanting, filtering and evaporating a decoction liquid, cooling before adding ethanol, allowing to stand to obtain a precipitate and a supernatant solution, collecting the supernatant solution, washing the precipitate with ethanol, combining the washed solution and a filtrate, recycling ethanol under a reduced pressure, filtering, and evaporating the filtrate at a low temperature to obtain a thick paste-like extract; and mixing the extract with an adjuvant, adding a lubricant to obtain a soft material, preparing a granule dosage form using a granulating machine, and performing sealing and packaging.
