Western medicine treatment of skin disease is to diagnose the disease, the treatment effect is fast, Chinese medicine is in the diagnosis and treatment, Chinese medicine believes that skin disease is the internal organs, qi, blood and fluid disease reflected in the skin, focusing on “urgent is to treat the root, slow is to treat the symptoms”, the combination of Chinese and Western medicine treatment can increase the effectiveness, but also to treat the root. The causes of skin disease can be divided into two categories: (a) general factors, which can be related to age, gender, occupation, environment, personal hygiene and social factors. For example, infantile eczema and pediatric eczema can be distinguished by age, and lupus erythematosus occurs mostly in women. Occupational skin diseases are related to occupation, and certain allergic reactions are related to exposure to certain atopic allergic objects in the environment. Scabies, impetigo, etc. are related to personal hygiene. Due to the superiority of our socialist system, certain serious infectious diseases (leprosy, yellow scabies, skin tuberculosis) have been controlled and eliminated. (B) the main cause of skin diseases:can be divided into external and internal causes. External causes can be mechanical (such as corns, umbilical service, etc.), physical (with mouth light, radiation, hot and cold, etc.). Animal (such as insect bite dermatitis, insect bites or dermatitis caused by the fur of animals, etc.). Plant-based (including lacquer, flowers, powder, vegetables, etc.). Chemical (including drugs, chemicals or chemical products). Microbiological (including various bacteria, viruses, molds and parasites, etc.). Internal causes can be divided into genetic causes, allergic causes, metabolic disorders, endocrine disorders, blood circulation disorders, impaired function of the nervous system, various mental factors or abnormal function of the digestive system, etc. (C) skin diseases are closely related to the internal organs, outside with wind, humidity, heat, insects, etc. Some skin diseases are allergic, and others are infectious. Chinese medicine has external and internal causes of disease, external causes include: wind, cold, heat, humidity, dryness, fire, dampness and heat insects, heat produces poison; internal causes include the seven emotions (joy, anger, worry, thought, sadness, fear, shock) and internal organs and disease, other causes such as phlegm, blood stasis and other causes of disease, as well as dietary disorders, trauma, abnormal labor and rest. (4) external causes of the six sexes and insect poison, phlegm, blood stasis, etc., is a certain cause of disease, that is, the so-called: “disease evil” to become phlegm. This understanding has clinical significance in guiding the prevention and control of disease, but must not be limited to external causes like Western medicine is said to be pathogenic bacteria and viruses or parasites. Because the external causes mainly represent the syndrome reflected by the body in the pathological situation, that is, the so-called “evidence”. For example, urticaria is caused by wind and cold. These patients may not have a history of wind and cold, but their clinical manifestations include fear of cold, wind masses all over the body, tight pulse, pale white tongue coating, etc. They belong to wind-cold evidence. The use of pungent and warming treatment to relieve the symptoms can be effective.
