Pain relief cream contains ingredients such as capsaicin and salicylates. These topical pain relievers may be scented or unscented, and are typically available over the counter (OTC). Special pain killing creams that require a doctor’s prescription are also available.
Capsaicin is a tasteless, odorless chemical compound that is insoluble in water. Found naturally in chili peppers, capsaicin provides a burning sensation that’s familiar to fans of Mexican cuisine and other hot, spicy cooking.
Salicylates contain the same pain reliever, acetylsalicylic acid, found in aspirin. In pain relief cream, this ingredient provides analgesic, antipyretic, and anti-inflammatory effects. Although aspirin has only mild side effects, pain clinic patients may complain of upset stomach.
