Statistics show that in the year just past, excessive and prolonged use of drugs led to the death of more than 200,000 people in China last year. Unreasonable use of medication leads to liver damage in a small number of patients. The liver is commonly known as “the chemical factory of the human body”. It is the main organ of concentration, transformation, metabolism, a variety of drugs must be oxidized through the liver, decomposition, detoxification. Drug abuse is bound to increase the burden on the already diseased liver. In addition, the toxic ingredients in the drug, the interaction between various drugs, may also produce some allergenic or even carcinogenic substances, resulting in liver cell re-damage, steatosis or fibrosis. At present, most of the proprietary Chinese medicines such as: Huang Yaozi, Lei Gongteng, Compound Qingdai Pills, He Shouwu, Qianli Guang, etc. are not modern pharmacology, toxicity and efficacy of the test, but only some of the experience of the formula. Long-term use is bound to aggravate the burden on the stomach, intestines and liver, especially in patients with liver disease, the liver’s detoxification capacity has decreased, so the choice should be guided by a doctor, and should not be too long to take the drug. China’s population has entered the stage of aging, the common diseases of the elderly also increase year by year, according to the physiological changes in the human body, men over 25 years old, women over 20 years of age, the liver’s circulating blood flow to an average of 0.3% -1.5% of the proportion of the decline in the age of 60 years old than the age of 20 years old to reduce the amount of 40% -50% of the blood is to protect and nourish the liver, the blood in the liver to reduce the volume of the liver, marking the liver’s blood circulation function of the weakening of the metabolic function, the detoxification of drugs and medicines, and the liver should not be taken. The metabolic function and the detoxification function of drugs also decrease accordingly, so the medication should be used reasonably. Hepatitis patients are eager to cure the disease, and they always think that they can recover fast if they take more medicines, resulting in some patients taking more and more medicines, and even taking medicines instead of meals, not realizing that after the medicines are absorbed, the concentration of the medicines in the liver is higher than that in the blood and other organs, and the result is that the more the medicines they take, the more they feel discomfort in abdomen, and the more the liver function is not normal, or even deteriorates. Hepatitis patients should be treated with appropriate rest, reasonable diet, under the guidance of the doctor to choose the correct principle of medication, the amount of medicine is small and precise, to achieve the purpose of liver protection and treatment of liver disease.
