Bathing with mugwort can effectively help remove heat rash from the body, as mugwort itself has the effects of relieving itching and dispelling cold. It can adjust the skin well, and can dredge meridians and promote blood circulation, leading to effective improvements. It is particularly effective in treating heat rash, especially in cases like itchy eczema. To prevent heat rash, it is crucial not to stay in damp environments for too long and to bathe regularly to maintain dryness.
