Deciduous water has almost no therapeutic effect on frostbite. The main function of deciduous water is to dispel heat, which is usually used in summer, while frostbite is mostly induced by cold and usually occurs in winter, so the treatment of frostbite is more suitable to use frostbite cream, heparin sodium cream, etc., which has the effect of promoting blood circulation. In addition to the above-mentioned creams, regular massage, warmth, proper exercise, improving immunity, and oral vitamin B3, also known as niacinamide, will also have some effect on frostbite. Ten drops of water belongs to Chinese medicinal preparations, and many traditional Chinese medicinal preparations in China have corresponding indications, so patients are advised not to abuse them themselves.
