Botanical name: Capsicum annuum L. var. annuum , Capsicum annuum
The term "cayenne" is often used to refer to any ground pepper, but true cayenne (which takes its name from the French Guinea city of Cayenne) is actually a particular type of chili pepper--about four to 12 inches long, thin, and very pungent.
Like other chili peppers, cayenne belongs to the genus Capsicum, a member of the nightshade ( Solanaceae ) family. Cayenne--and most other hot and sweet peppers grown in the U.S.--is Capsicum annuum, while Capsicum frutescens produces the small, thin-skinned pepper from which Tabasco sauce is made. The name capsicum may have been derived from the Latin capsa for "box" (the pepper is mostly a hollow, box-like fruit), or the Greek kapto, "to bite."
Technically, chili peppers are a fruit; once dried they are correctly considered a spice.
An annual, herbaceous plant, the personality of Capsicum annuum depends a great deal on the neighborhood in which it grows up. A hot, dry environment, for example, produces the hottest chilies, while milder ones are produced in cooler, wetter climates. Even the same variety of pepper will differ, depending upon its locale.
There are several scales for measuring the hotness of chilies. What they actually measure is the capsaicin content, the crystalline, pungent substance that gives chilies their fire. The most popular scale is the Scoville Organoleptic test, which assigns a number between 0 and 300,000 heat units (the higher the number, the hotter the pepper). Cayenne typically measures between 30,000 and 90,000 heat units on the Scoville scale.
In his search for peppercorns, Columbus found "agi" pods, which the Indians used in cooking. Although technically no relation to black peppers, the Spanish called the pods "peppers," and the name stuck. Early explorers sent the seeds back to Europe, where their popularity quickly spread; soon chili peppers were commonly used to flavor bland food all over Europe. Like many cayenne lovers today, both the Edwardians and the Victorians placed chili powder shakers on their tables. Researchers are studying the pain-reducing effect of capsaicin. One theory is that capsaicin triggers pain-detecting nerves in the mouth, nose and throat, which in turn motivate the brain to release natural painkillers (endorphins). Other studies suggest that capsaicin may lower blood pressure, reduce blood clot formation, and/or prevent or heal ulcers (by stimulating the flow of digestive juices).
