The capsicum family includes red peppers, bell peppers, pimento, and paprika, but the most famous medicinal member of this family is the common cayenne pepper.
Cayenne and related peppers have a long history of use as digestive aids in many parts of the world, but the herb's recent popularity has, surprisingly, come through conventional medicine.
What Is Cayenne Used for Today?
Many people think that hot peppers cause inflammation to tissues, and that this is the source of the classic hot pepper sensation. However, hot peppers don’t actually have any damaging effect; they merely simulate the sensations produced by damage. (Herbs like garlic
Here’s how it works: All hot peppers contain a substance called capsaicin. When applied to tissues, capsaicin causes release of a chemical called substance P. Substance P is ordinarily released when tissues are damaged; it is part of the system the body uses to detect injury. When hot peppers artificially release substance P, they trick the nervous system into thinking that an injury has occurred. The result: a sensation of burning pain.
When capsaicin is applied regularly to a part of the body, substance P becomes depleted in that location. This is why individuals who consume a lot of hot peppers gradually build up a tolerance.
It’s also the basis for a number of medical uses of capsaicin. When levels of substance P are reduced in an area, all pain in that area is somewhat reduced. Because of this effect, capsaicin cream is widely used for the treatment of various painful conditions.
Under the brand name Zostrix, a cream containing concentrated capsaicin has been approved by the FDA for the treatment of post-herpetic neuralgia, the pain that often lingers after an attack of

Cayenne can be taken internally as well. It appears that oral use of cayenne might reduce the pain of minor indigestion (

Topical Uses of Cayenne
All double-blind studies of topical capsaicin (or cayenne) suffer from one drawback: It isn’t really possible to hide the burning sensation that occurs during initial use of the treatment. For this reason, such studies probably aren’t truly double-blind. It has been suggested that instead of an inactive placebo, researchers should use some other substance (such as camphor) that causes at least mild burning. However, such treatments might also have therapeutic benefits; they have a long history of use for pain as well.
Because of these complications, the evidence for topical treatments cited below is less meaningful than it might at first appear.
Capsaicin cream is well established as a modestly helpful pain-relieving treatment for
Actual cayenne rather than capsaicin has been tested for pain as well. A 3-week, double-blind trial of 154 individuals with
A double-blind, placebo-controlled trial of nearly 200 individuals found that use of topical capsaicin can improve itching as well as overall severity of
Capsaicin creams are approved over-the-counter drugs and should be used as directed. If the burning sensation that occurs with initial use is too severe, using weaker forms of the cream at first may be advisable.
For treatment of dyspepsia, cayenne may be taken at a dosage of 0.5 to 1.0 g three times daily (prior to meals).
Capsaicin creams commonly cause an unpleasant burning sensation when they are first applied; this sensation disappears over subsequent days as treatment is continued.
