Dr. Xu Yin, deputy director of the famous old Chinese medicine doctor in Hailing, has been practicing for more than 40 years and has rich clinical experience, especially in the treatment of spleen, stomach, liver and gallbladder diseases. Now, we will only make a brief introduction on the experience of Xu Yin in treating chronic and prolonged hepatitis by using the method of dredging the liver and gallbladder, strengthening the spleen and neutralizing, and clearing heat and detoxification: 1. “The pathogenesis of chronic prolonged hepatitis is complex and the course of the disease is protracted. According to Xu, the disease is initially caused by internal dampness and external dampness and heat toxins that block the qi flow, resulting in liver depression and qi stagnation, and stasis due to obstruction of blood flow in the liver. The dampness, heat, stasis and toxicity are intertwined, and over time the vital energy is damaged, the immune regulating function decreases, and the body is unable to resist the evil out, so the disease is lingering and difficult to be cured. Liver disease transmits to the spleen, the spleen loses its health, dampness and turbidity are stored inside, and phlegm is generated over time. Therefore, the evil of dampness and toxicity is the main cause of this disease, and the deficiency of liver and spleen, and the deficiency of evil is the basis of this disease. 2. The treatment of chronic prolonged hepatitis (dredging the liver and bile, strengthening the spleen and the middle, detoxifying and clearing heat) Xu has accumulated many years of clinical experience and concluded the basic formula for dredging the liver and bile, strengthening the spleen and the middle, and clearing heat and detoxifying heat: Chai Hu, Orange Shell, White Peony, Dang Shen, Atractylodes Macrocephalae, Poria, Yin Chen, Huang Ling, Coix Seed, Grain Malt, Licorice. This formula is a combination of Xiao Chai Hu Tang, Yin Chen Artemisia Tang, Iso Efficacy, and Si Wei San. The formula uses Si-wei-san to dredge the liver and relieve depression, Si-jun-zi to benefit Qi and strengthen the spleen, Coix lacrymae and Gu-mei-malt to eliminate food and harmonize the middle, and Yin-chen and Huang-ling to clear heat and detoxify yellow. Add and subtract according to the evidence: for heat and toxicity, add gardenia, dandelion, stone dart, half a lotus, half a lotus; for qi stagnation and blood stasis, add salvia, Chuanxiong, orange lily skin, raw cypress, red and white peony; for spleen and stomach weakness, add papaya, yellow ling, sand, coix seed yam, hawthorn, white lentil, gorgonian; for liver and kidney yin deficiency, add prince’s ginseng, wolfberry, sage, dogwood, asparagus, mulberry, chasteberry, dry lotus grass. 3, the characteristics of the medication 3.1 care for the spleen and stomach, always implement, Xu Lao believes that: chronic prolonged hepatitis, regardless of its cause of damp heat, toxicity, silt or evidence of deficiency is real, treatment to clear the liver and gallbladder as a prerequisite, must not forget to care for the spleen and stomach. The spleen is the source of the posterior, the source of biochemical energy, spleen health, can not only Du liver wood, but also nourish the liver wood, and can be conducive to the recovery of liver disease. Clinically common in patients with liver disease, if the spleen and stomach function is normal, the efficacy is higher, the course of treatment is shortened, the disease remission or recovery is fast, such as poor spleen and stomach function, the efficacy is slower; the course of treatment is long, the disease remission or recovery is slow. Therefore, in the treatment of chronic hepatitis, we must follow the principle of “when we see the disease of liver, we know that the liver transmits the spleen, so we should first strengthen the spleen. Commonly used formulas include Seven Flavors of Atractylodes Macrocephalae, Ginseng and Atractylodes Macrocephalae, and Tonic Central Beneficial Qi Tang. 3.2 Combining modern medical test results and pharmacological research, Xu Lao’s treatment of chronic prolonged hepatitis emphasizes modern medical test results and combines them with modern pharmacological research to guide clinical use. For example, for anti-hepatitis B virus, Astragalus, Ginseng, Radix et Rhizoma, Coix Coix seeds, Yinhua vine, Lycium barbarum, etc. are often used for deficiency; for solid evidence, Chai Hu, Half-branch lotus, Danshen, etc.; for heavy jaundice, Damp-Heat, Yin Chen, Qing Dai, Gardenia, Huang Ling, etc. are used; for Blood-Heat, Danshen, Red Peony, Dan Pi, Comfrey, etc. are used; for lowering transaminase, Damp-Heat poisonous evil, Dandelion, Huang Ling, Drapery, Stone For those with blood stagnation, use Danshen, Radix Paeoniae, Dampi, White Peony; for those with liver and kidney deficiency, use Wu Wei Zi Wolfberry, White Peony, Poria, Tian Men Dong, Papaya, Cornu Cervi Pantotrichum, Tortoise Plate, Turtle Nail; for serum albumin drop, Baji Tian, Tortoise Plate Gum, Atractylodes, Poria, etc.; for anti-liver fibrosis, use Danshen, Radix Paeoniae, Yin Chai Hu, Yu Jin, Silphium, Tangerine, Ginger, Papaya, Lulutong, Raw Cypress, Aloe, etc. Lactation, etc. 4, case example Example 1.
