2. No harm to gastrointestinal tract: When patients take medicine, they first enter the stomach and then absorb it. The irritation and injury of drugs to gastrointestinal tract is a headache, especially some patients with poor stomach condition who have to take medicine often fall into the dilemma of taking medicine to treat their old diseases and stomach diseases. Then there is no such problem in external treatment of drugs. As the saying goes, "a good medicine tastes bitter and is good for the disease", and the spasm of taking medicine is unbearable for many patients for a long time. External use of traditional Chinese medicine can play the role of "good medicine tastes bitter and is good for disease".
3. Small irritation to liver and kidney: No matter what kind of drugs are taken orally, they are absorbed into the blood through the gastrointestinal tract, and their metabolites, especially some toxic products, must be detoxified by the liver and excreted by the kidney, which is also an unavoidable contradiction for patients with liver and kidney diseases. The external treatment of traditional Chinese medicine is mostly absorbed through the skin and mucosa, and the components of the medicine have entered the body through a barrier, and the harmful components are already very small and weak, so it is inevitable for the liver and kidney.
Therefore, external therapy not only acts on the body surface absorption of effective components of drugs, but also stimulates specific parts and acupoints through drugs, thus dredging meridians, regulating menstruation and regulating functions, which can play the same role as acupuncture and massage. Simple operation, easy to obtain materials: most of the external use of traditional Chinese medicine acts on acupuncture points and specific parts of the human body, which are easy to argue and master. As long as you study and pay attention, most of them can be operated by yourself, such as medicine pillow therapy, umbilical application, foot-foot-heart application, liver application, eye-point application, ear-nose insertion and so on.
