  • Capsaicin creams and patches relieve nerve pain after shingles and in diabetic neuropathy.

  • A warming liniment draws blood into bruised, sprained, and strained tissue.

  • Wakes a poor appetite and warms a cold, slow digestion.

Folklore

Chilies were domesticated in Mexico at least six thousand years ago. Columbus, sailing for the black pepper of the Indies, called them pimientos after a spice they are not related to, and within a century Portuguese traders had carried them around Africa and Asia. In 1912 the pharmacist Wilbur Scoville measured their heat by diluting extracts until a panel of tasters could no longer feel the burn. Birds cannot feel capsaicin at all; they eat the fruit and scatter the seeds, while mammals, whose teeth would crush them, are kept away.

How to grow

A tender perennial grown as an annual. Start seed indoors on a warm mat eight to ten weeks before the last frost, and plant out once nights stay warm, in full sun and rich, well-drained soil. Pick the pods when fully red and string them up to dry.

In the wild

Its wild ancestor, the tiny chiltepin, still grows in thorn scrub and canyon bottoms from southern Arizona and Texas through Mexico into South America.
