I have been engaged in medical research and development for more than ten years, and have studied this Li Shizhen hot moxibustion ointment. In fact, it is plaster hot compress therapy. It uses 700 grams of plaster and is refined from 48 kinds of precious Chinese herbal medicines. It can dredge channels and collaterals, promote blood circulation and remove blood stasis, and dispel wind and cold through hot drugs, so it has a good effect on regulating rheumatic bone pain and dysmenorrhea, including improving human immunity.
