Materia medica: Capsicum annum


Cayenne ripening in the greenhouse

Family: Solanaceae (Nightshades)

Nomenclature:

  • Botanically, most cultivated peppers today are Capsicum annuum (most common), C. frutescens (tabasco), C. chinense (habanero), or crosses within and among these various species (Missouri Botanical Garden, 2020).

  • The other domesticated species include Capsicum baccatum (ají, ají amarillo) and C. pubescens (rocoto, manzano) (Fett, 2003).

  • Capsicum is derived from the Greek word "kapto", meaning "to bite", or the Latin word "capsa" meaning "box" or "capsule", which is likely a reference to the capsule shaped fruit. (Missouri Botanical Garden, 2020).

  • Annum - meaning grown annually

Common Names (American Botanical Council, 2003):

  • Common names for cayenne (depending on species) include cayenne pepper, chili pepper, paprika, red pepper, tabasco pepper, bird pepper, African bird pepper, piquin, aji pepper, Brown’s pepper, Peruvian pepper, piris, habañero pepper, and bonnet pepper.

Parts Used: Dried ripe fruit (whole), powdered

Botanical ID:

  • Native to Zones 9-10, where it grows as a wild and cultivated perennial in the Tropical South and Central America

  • Cultivated as a shrubby annual in the Northeast, typically in gardens or greenhouses.

  • Plant height ranges between 2.5-6' in height, depending on species and growing conditions

  • Leaves are oval/lanceolate in shape and bright green

  • Flowers are off-white to white, giving way to characteristic hollow, berry-like fruit

  • Fruit is red, shiny, ovate and long. Contains seeds small and flat, 10-29 per per fruit (Henningsen, 2019)

  • Ethnobotanical researchers have determined that C. annuum was first domesticated in Mexico or northern Central America, C. frutescens in the Caribbean, C. baccatum in Bolivia, C. chinense in northern Amazonia, and C. pubescens in the southern Andes (Linder, 2008).

Growing & Harvesting:

  • A minimum temperature of 70 degrees is desired for prolific fruiting

  • Start seeds indoors in late march-early April. Placing seed trays over warm seed mat will help with germination.

  • Prefers drier soils, and will tolerate acidic to alkaline conditions.

  • Full-sun is best, plants do not tolerate shade well.

  • Fruits will deepen color the longer they are left on plant to ripen.

  • Harvest whole fruits throughout season as they ripen. Continuous harvest will promote more growth.

  • Can dry entire plant upside down, dry fruits on racks or in dehydrator, or string with needle and thread. Keep drying plants/fruits out of direct sunlight and maintain good airflow.

  • Wear gloves when dealing with dried plants and be cautious of rubbing face and eyes - capsaicin, the pungent constituent in cayenne will cause irritation!

Commercial Availability (Henningsen 2019):

  • Widely available in commerce, generally found in dried form, such as powders or whole fruit.

  • Tinctures

  • Vinegar infusions

  • Pure capsaicin products, such as topical sprays, gels, and ointments are also found in commerce
