In traditional Chinese medicine, medicated bath is a kind of external treatment, that is, bathing the whole body or part with liquid medicine or water containing liquid medicine, which has many forms: bathing the whole body is called "medicated bath"; Local baths are also called "scalding", "fumigation", "sitting bath" and "foot bath", especially scalding. Medication in medicated bath, like internal medicine, also needs to follow the principle of prescription and medicine, and select drugs based on disease differentiation and syndrome differentiation. That is, according to one's own constitution, time, place, illness and other factors, choose different prescriptions and belong to their respective genera. The specific methods of decocting and bathing are also particular: crushing the medicine and wrapping it with gauze (you can also put the medicine directly into the pot and decoct it with water). When making, add a proper amount of water, soak for 20 minutes, cook for 30 minutes, pour the liquid medicine into the basin, and take a bath when the temperature is moderate. In bathing, there are two methods: fumigation and bathing.

In short, the mechanism of action of medicated bath is that drugs act on the muscle surface, local parts and affected parts of the whole body, are absorbed, circulate the meridians and blood vessels, and reach the viscera from the outside to the inside, thus producing effects. The medicated bath has the effects of dredging meridian passage, promoting blood circulation, removing blood stasis, expelling pathogenic wind and cold, clearing away heat and toxic materials, relieving swelling and pain, regulating yin and yang, regulating viscera, activating qi and blood, and nourishing the whole body. Modern pharmacology has also confirmed that medicated bath can increase the content of some immunoglobulins in blood and enhance the elasticity and vitality of skin.
