Acid-expelling ointment can regulate the acidic constitution of human body and expel lactic acid from the body, thus achieving the functions of acid-expelling, dampness-expelling, cold-expelling and toxin-expelling. The acid-expelling blanket does not need to use acid-expelling paste, but can help the human body to sweat and dissipate heat through physical cooling, thus alleviating some uncomfortable symptoms, such as leg pain, rheumatism, body aches, skin allergies, skin diseases and so on.
