With the progress of science and medical technology, new treatment methods and new drug development are constantly emerging, which also bring some inevitable side effects, and some people are afraid to go to the hospital for examination and medication, often delaying the diagnosis and treatment of the disease. It is an undisputed fact that traditional Chinese medicine is safe and has no side effects, but this is not the case. With the widespread use of traditional Chinese medicine, some side effects of traditional Chinese medicine have been reported one after another, such as Andrographis injection and Shuanghuanglian oral solution, which cause side effects such as skin allergy and fever. There are serious reports of some herbal medicines causing kidney failure and drug-related hepatitis. There are some individual herbalists who pride themselves on making good use of some toxic mineral-based herbal medicines, which often lead to serious side effects, so such medicines often contain toxic heavy metal-based harmful substances. The classic medical books of Chinese medicine also detail the 19 fears and 18 objections of Chinese medicine, which are meant to remind people to pay attention to the side effects of Chinese medicine. In conclusion, the safety, reliability, and effectiveness of medication, regardless of Western medicine, should be trusted when used under the guidance of a doctor.
