Bird pepper is a small, very hot chilli used as food and as a home remedy. Its botanical name is Capsicum frutescens. In the Caribbean it is eaten daily and also rubbed on sore joints.
You may know it as hot pepper in Jamaica and Trinidad, piman bouk in Haiti, or ají caballero in Cuba. The pods are used fresh, dried, or steeped in vinegar or rum. Tabasco-type peppers belong to this same species.
Here is the short verdict. Purified capsaicin, the heat chemical in the pepper, has solid human evidence as a skin treatment for certain nerve pains. The pepper itself, eaten or applied as a home rub, is far less studied.
Long use in a tradition is not proof that something works. It is also not proof that it is safe. Both points apply to everything on this page.
Capsaicin is the chemical that makes bird pepper hot. It acts on TRPV1, a sensor on nerve endings that normally reports heat and pain.
In people, strong capsaicin creams and patches first cause burning. With repeated use, the treated nerve endings go quiet for weeks. This effect is well documented in pain trials.
The other claims are far less settled. In lab and animal work, capsaicin appears to raise heat output and dampen appetite a little. Whether that shifts body weight in people is not established.
In test tubes, pepper extracts slow the growth of some bacteria. That does not mean they treat infection in the body.
Eating hot pepper also makes your nose run and your eyes water. That is a nerve reflex, not a medicine clearing your sinuses.
Most bird pepper is sold as food. Fresh and dried whole pods are the common forms.
Pepper sauce and pepper wine are Caribbean staples. Both are made by steeping the pods in vinegar or in rum.
Ground powder and dried flakes are also sold widely. Cayenne powder is a close relative and is often used in the same way.
Capsules of cayenne or capsicum powder are sold as supplements. Strength and heat differ a lot between brands.
Pharmacies sell capsaicin creams, gels and patches for pain. These use purified capsaicin at a stated strength, not whole pepper. The strongest patch is applied in a clinic, not at home.
Bird pepper has a long record in Caribbean kitchens and home care. Healers across the islands used pepper rubs for aching joints and cold, stiff limbs.
It was also taken in food and drink for chills, poor appetite and slow digestion. Pepper teas, pepper sauce and pepper wine were ordinary household items.
The plant came from tropical America and spread with trade and settlement. It became part of African-Caribbean and Creole cooking and bush medicine. Hot pepper is still eaten daily across the region.
Stop and get medical help the same day if skin under a pepper rub or cream blisters, breaks down or stays painful after you wash it off.
Rinse your eye with plenty of clean water if pepper gets in it. See a doctor if pain, redness or blurred vision lasts more than an hour.
Go to an emergency department now if you have swelling of the lips, tongue or throat, trouble breathing, or a widespread rash after eating pepper.
Seek urgent care for severe chest or stomach pain, vomiting blood, or black tarry stools after a very large chilli intake.
See your doctor if heartburn, stomach pain or loose stools keep going after you stop using pepper products.
Bird pepper is an ordinary food worldwide and is sold freely. Capsule supplements are regulated as food supplements in the UK, EU and US, not as medicines.
Capsaicin creams are regulated as over-the-counter medicines in many countries. The 8% capsaicin patch is prescription-only in the US and EU.
