Cayenne

background

Cayenne is a spice derived mainly from two cultivated species of the Capsicum genus, Capsicum annuum L. and Capsicum frutescens L. Capsicum adds color, pungency, and aroma to dishes around the world. Although originally cultivated in the tropical Americas, it is now grown worldwide. Capsicum annuum is cultivated almost exclusively in Europe and the United States, and Capsicum frutescens is cultivated in the tropics and warmer regions of the United States.
The level of pungency (heat) of the Capsicum species depends mainly on the concentration of capsaicinoids, primarily capsaicin. Chili peppers and red peppers come from plants with capsaicinoid levels 30-600 parts per million and 600-13,000 parts per million, respectively. Paprika is derived from plants with lower levels of capsaicinoids and is used to flavor less spicy foods, such as ketchup, cheese, and salads. Spanish paprika (pimento) is mainly used for coloring. The more spicy chilies and chili pepper from Capsicum annuum L. and Capsicum frutescens L. are used in curry powder, Tabasco® sauce, and chili powder. Cayenne pepper is made by grinding the pungent fruit of Capsicum into a powder.
Overall, clinical evidence is good for the use of topical Capsicum in a plaster for low back pain and at various acupoints for postoperative pain, nausea, and vomiting. Cayenne pepper is approved by the Commission E as a topical ointment for the relief of painful muscle spasms. The mechanism of action for topical pain relief by Capsicum is well studied. It is likely that the pain-relieving effect of pungent Capsicum spp. is due to capsaicin.
Capsicum is traditionally used for other purposes, including (but not limited to) weight loss, sore throat, tonsillitis, gastrointestinal disorders, diabetes, cardiovascular disorders, muscle pain, and skin conditions. However, clinical support for Capsicum for these uses is lacking. The main constituent of Capsicum, capsaicin, has also been investigated in clinical study.
Cayenne was proposed as a chemical weapon during the American Civil War. Today, oleoresin of Capsicum has mostly replaced use of earlier riot control agents, such as chloroacetophenone and chlorodihydrophenarsazine.
Capsicum essential oil and cayenne pepper are listed in the U.S. Food and Drug Administration (FDA) Generally Recognized as Safe (GRAS) list for use as a spice in foods. When used orally, Capsicum may cause gastrointestinal irritation, mouth and throat irritation, damaged taste buds with reduced ability to taste foods, fullness, flatulence, dyspepsia, diarrhea, ulcer aggravation, and stomach pain. Based on secondary sources, large amounts may cause kidney and liver damage. Topically, Capsicum may cause burning, redness, and irritation. Inhalation of Capsicum may cause dyspnea and cough. It may also irritate mucous membranes.

Note: This monograph focuses on cayenne and pungent Capsicum spp. and does not specifically include clinical trials investigating the effects of isolated capsaicin or information on nonpungent varieties of Capsicum. However, due to the nature of Capsicum (pungent and nonpungent varieties within the same species and occasionally the same variety), some information on nonpungent Capsicum is included.

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
 
Low back pain (topical plaster) (Grade: B)
Good evidence suggests that cayenne may reduce lower back pain when applied to the skin. Additional research is needed to reach a strong conclusion about dose, duration, and safety.
Post-operative nausea / vomiting (plaster at acupoint) (Grade: B)
plaster at acupoints, an alternative to acupuncture, has been studied as a means to reduce postoperative nausea and vomiting with promising results. Based on available studies,

Cayenne plasters at acupoints reduced postoperative pain and the need for pain-relieving medications. Further study on dose, duration, and safety is still required.
Diabetic neuropathy (Grade: C)
Capsaicin cream may help reduce pain associated with diabetic nerve damage (neuropathy). However, additional research is needed to confirm these findings.
Duodenal ulcer (Grade: C)
It is unclear if chili peppers are helpful for duodenal ulcers. Additional research is needed in this area.
Dyspepsia (Grade: C)
