What is capsicum?

Capsicum is a small, spreading, annual shrub that grows wild in tropical America and is now cultivated around the world. It produces an oblong, pungent fruit (peppers). The fruit of the plant is used to make medicine.

What is it used for?

Besides being used in food as a pepper or spice, capsicum has been used in medicines. The active, medicinal ingredient used from the pepper is called capsaicin.

Capsaicin is used in skin creams to treat pain from shingles, arthritis, fibromyalgia, and nerve pain in people with diabetes.

Capsaicin is also taken by mouth to treat cramps, diarrhea, toothache, blood clots, fever, nausea, high cholesterol, and heart disease. It is also used to stimulate digestion.

Capsaicin is the ingredient used in pepper spray for self-defense.

How is it taken?

Capsicum is available as peppers, capsules, seasoning, and as a tincture for use by mouth. It is also available in creams, ointments, and lotions for use on the skin.

Follow the directions printed on the product label or given by your health care provider.

What should I watch out for?

Do not use creams or ointments containing capsaicin if you have:

  • an allergy to pepper
  • broken or irritated skin.

Do not take capsicum by mouth if you have:

  • an allergy to pepper
  • stomach problems such as ulcers or irritable bowel syndrome.

Keep ointments or creams containing capsaicin away from your eyes, nose, and mouth. If some gets into your eyes, nose, or mouth, flush them with a dilute vinegar solution or lots of cool water.

Do not use tight bandages over skin that has been treated with capsicum because it will make the burning sensation worse. Do not use with a heating pad or apply right before or after a hot shower.

Eating too much capsicum could cause stomach pain and kidney and liver damage. Do not take capsicum by mouth in large doses or for long periods of time.

If you take an ACE inhibitor such as captopril (Capoten), enalapril (Vasotec), or lisinopril (Prinivil, Zestril) for your blood pressure, using capsaicin cream on the skin may cause you to develop a cough. If you develop a cough while using the cream, stop taking it and contact your health care provider.

If you need emergency care, surgery, or dental work, tell the health care provider or dentist that you are taking this remedy. It may cause you to bleed more.

Females of childbearing age: Do not take this remedy by mouth if you are pregnant or breast-feeding.
