Capsaicin is an external analgesic available in over-the-counter (OTC) medicines that temporarily relieve minor aches and pains associated with arthritis, simple backache, strains and sprains, and bruises. Capsaicin is also the chemical that makes chili peppers taste hot. When used as an active ingredient in topical pain relief medicines, capsaicin produces a warming sensation in the treated area. It can be found in single- and multi-ingredient topical pain relievers.
