Hot hands from chili peppers can be washed with vinegar, rubbed with alcohol as well as washed with soap. Chili peppers are hot because chili peppers produce capsaicinoids, which cause small blood vessels to dilate on the skin and stimulate the nerves that feel pain, so this symptom will occur. 1. Wash your hands with vinegar: Vinegar is acidic and can neutralize capsaicinoids and improve the symptoms of hot hands. 2. Rubbing with alcohol: Alcohol can dissolve capsaicinoids, using a cotton ball dipped in alcohol or white wine, and then repeatedly wiping and then rinsing with water can relieve the irritation of chili peppers on the hands. 3. Hand washing with soap: capsaicin tends to be around the pores, so soap and water with alkaline solution can remove these capsaicin and relieve the symptoms. If the hot hand feeling serious, with the above methods can not be relieved, can be treated with topical hydrocortisone butyrate ointment and other glucocorticoid ointment, if necessary, can go to the hospital.
