Chinese medicine fumigation therapy, also known as steam therapy, steam bath therapy, Chinese medicine atomization transdermal therapy, is a Chinese medicine external treatment therapy guided by the theory of Chinese medicine, using the steam generated by the decoction of drugs to achieve the purpose of treatment by fumigation of the body. As early as in the Yellow Emperor’s Classic of Internal Medicine, there is a saying of “Mozhi Bath”, and “Li Yu Jiao Wen” has pointed out that “the theory of external treatment is the theory of internal treatment; the medicine of external treatment is the medicine of internal treatment, but the only difference is the method”. Practice has proved that Chinese medicine fumigation treatment therapy is direct, effective, wide range of indications, non-toxic side effects. The skin is the largest organ of the human body, with a large area and many pores. In addition to the protective effect of defending against external invasion, it also has various functions such as secretion, absorption, penetration, excretion and sensation. Chinese medicine fumigation treatment therapy is to take advantage of this physiological characteristic of the skin, so that the drug is absorbed through the skin surface, the corneal layer penetration and dermal transit into the blood circulation and play the pharmacological effect. Chinese medicine fumigation combines the functions of Chinese medicine therapy, heat therapy, steam therapy, and Chinese medicine ion infiltration therapy, etc. It integrates heat, humidity, and drug concentration, and can effectively treat a variety of skin diseases with disease-specific treatment and symptomatic drugs. Through adjustable Chinese medicine fumigation treatment method, using computer-controlled Chinese medicine physical therapy, directly steaming Chinese medicine, eliminating the traditional kind of need to first decoction of Chinese medicine into liquid complicated process, through the source of hot drug steam by convection and conduction directly on the body, expansion of local and systemic blood vessels, promote the blood circulation of body surface tissues, improve the absorption of the skin, promote the sweat glands of a large number of At the same time, the Chinese medicine particles (molecules or ions) escaping from the fumigated medicine act directly on the body surface to produce insecticide, sterilization, anti-inflammatory, anti-itch, pain and other effects, or through transdermal absorption of the body through the biochemical process of stimulating tissue cell receptors to play a pharmacotherapeutic role, thereby eliminating the lesions.
