Historical or traditional use: The potent, hot fruit of cayenne has been used as medicine for centuries. It was considered helpful for various conditions of the gastrointestinal tract, including stomachaches, cramping pains, and gas. Cayenne was frequently used to treat diseases of the circulatory system. It is still traditionally used in herbal medicine as a circulatory tonic (a substance believed to improve circulation). Rubbed on the skin, cayenne is a traditional, as well as modern, remedy for rheumatic pains and arthritis due to what is termed a counterirritant effect. A counterirritant is something which causes irritation to a tissue to which it is applied, thus distracting from the original irritation (such as joint pain in the case of arthritis).
Active constituents: Cayenne contains a resinous and pungent substance known as capsaicin. This chemical relieves pain and itching by acting on sensory nerves. Capsaicin temporarily stimulates release of various neurotransmitters from these nerves, leading to their depletion. Without the neurotransmitters, pain signals can no longer be sent.1 The effect is temporary. Capsaicin and other constituents in cayenne have been shown to have several other actions, including reducing platelet stickiness and acting as antioxidants.
How much should I take? Creams containing 0.025-0.075% capsaicin are generally used. There may be a burning sensation for the first several times the cream is applied, but this should gradually decrease with each use. The hands must be carefully and thoroughly washed after use, or gloves should be worn, to prevent the cream from accidentally reaching the eyes, nose, or mouth, which would cause a burning sensation. Do not apply the cream to areas of broken skin. A cayenne tincture can be used in the amount of 0.3-1 ml three times daily.
Are there any side effects or interactions? Besides causing a mild burning for the first few applications (or severe burning if accidentally placed in sensitive areas, such as the eyes), there are no side effects from use of the capsaicin cream. Very high intake of cayenne internally may cause ulcers, but the necessary amount is rarely achieved with sensible intake.
As with anything applied to the skin, some people may have an allergic reaction to the cream, so the first application should be to a very small area of skin.
