In recent years, with the continuous development of new clinical drugs, medically induced liver injury has become a very important problem, involving almost about 1,000 drugs. Drug-induced liver disease accounts for about 10% of patients with clinical hepatitis and can exceed 40% in patients over 50 years of age. In the 21st century, there are more than 30,000 kinds of drugs and health products for human application, and together with food additives and environmental pollutants, human beings are being exposed to the threat of more than 60,000 kinds of chemical substances. That is to say: you can also get hepatitis from taking medicine. When it comes to hepatitis, people will naturally think of “Hepatitis A”, “Hepatitis B”, “Hepatitis C”, “Major and Minor Triple Positive “. In fact, in the hepatitis family, there are alcohol hepatitis, autoimmune hepatitis B, drug hepatitis and other categories. Among them, the harm is widespread, but not for people to pay attention to, and the number of patients in the minority and drug hepatitis, unauthorized use of drugs beware of incurring drug hepatitis. Drugs into the human body, the main metabolism, detoxification site is the liver. If the drug has toxic side effects, the first to be damaged is naturally the liver. Specifically to each person with drugs whether liver damage occurs, in addition to the role of the drug itself, and individual differences also have a great relationship, that is, with the individual body liver enzymes related to the situation. Drug-induced hepatitis can be categorized as acute, subacute, or chronic, and in severe cases, there can be fulminant hepatic failure, with sudden and massive necrosis of liver cells, and the patient may die within one to two weeks. Drug hepatitis can be a result of direct drug toxicity or an allergic reaction, i.e., liver damage mediated by immune mechanisms. Drug induced hepatitis has an incubation period of two to eight weeks, with initial symptoms of fever, jaundice, rash or itching, increased eosinophilia in the peripheral blood, and elevated serum aminotransferases and alkaline phosphatase characterizing the liver function on laboratory tests. Herbal medicines can also cause drug hepatitis. Many people think that herbal medicines are highly safe, have few toxic side effects and rarely cause liver damage. However, in recent years, it has been found that the adverse reactions caused by Chinese herbal medicines and their preparations have been increasing year by year. The reason, in addition to the cultivation of pesticide residues in the herbs and varieties of confusion, etc., the toxic side effects of Chinese herbal medicine itself should not be ignored. According to the literature, the Chinese medicine “Jin Buwang painkiller” has the effect of tranquilizing the mind and relieving pain, as a traditional medicine has been used in our country for more than a thousand years, but some doctors found that: there are individual patients who take the regular dose of Jin Buwang tablets for an average of twenty weeks led to acute hepatitis, in which some patients appear abdominal pain and jaundice, transaminases and serum alkaline phosphatase The liver biopsy confirmed drug-induced hepatitis, and the patient returned to normal after discontinuing the drug, and there may be alkaloids in the tablets that cause hepatocellular damage. It can be seen that not all herbal medicines are very safe, we should follow the doctor’s instructions to take herbal preparations, avoid exceeding the prescribed amount and long-term use, can not be used externally for internal use, and take a cautious attitude towards folk single prescription in order to prevent poisoning. Therefore, it is necessary to cultivate the concept of scientific medical care, not unauthorized use of drugs, so as not to invite the harm of drug hepatitis.
