Capsaicin is the substance in chili peppers that gives them their heat,1 but capsaicin has a lot more to offer than just spicing up your meals. De hecho, it’s a powerful natural pain reliever2 that’s been used to help control joint and muscle discomfort for centuries.3
Substance P is a chemical in your body that acts as a neurotransmitter, moving pain impulses along the synapses in your central nervous system. When substance P enters joint tissue, it causes inflammation and contributes to rheumatoid arthritis.
Capsaicin helps relieve pain by preventing the accumulation of Substance P in peripheral sensory neurons. When there’s less Substance P in your nerve endings, pain impulses aren’t transmitted to the brain. Essentially, capsaicin prevents your brain from receiving the impulses that would otherwise make you feel pain.
Capsaicin has been used for over 6000 years
Capsaicin was first isolated by John Clough Thresh. The exact chemical structure of capsaicin was determined by E. K. Nelson in 1919. It was synthesized by Ernst Spath and Stephen F. Darling in 1930.4
Although those technical advances are recent, chili peppers have been used in one way or another for over 6,000 years.5 The analgesic properties of chili peppers have been appreciated by cultures around the world. Native Americans, in particular, were known to rub their gums with chili pepper pods to relieve tooth pain.
Culinary applications are also common. Chili peppers were used as a weapon by the Incas against the Spaniards. In recent years, law enforcement has taken to using capsaicin-based pepper spray.6
9 surprising uses for capsaicin
Significant research has confirmed the impressive benefits of capsaicin. Medline lists almost 2900 research mentions of capsaicin in scientific literature published between 1991 and 1999 alone.
Although far from everything this compound has to offer, here are nine impressive health benefits of capsaicin you should know about…
UN 1986 study found patients with moderate or severe psoriasis who applied topical capsaicin had significant less burning, stinging, itching, and redness of the skin over a six-week period.7
Capsaicin may help with atopic dermatitis.8
UN 1991 study found capsaicin may be an effective remedy for arthritis. Rheumatoid arthritis and osteoarthritis patients who received capsaicin cream for painful knees experienced mean reductions in pain of 57 percent and 33 por ciento, respectively, after 4 weeks.9
4. Back pain:
Capsaicin helps with chronic back pain.10
5. Soft tissue pain:
Capsaicin may relieve chronic soft tissue pain.11
6. Nerve pain:
Capsaicin may provide relief for neuropathic (nerve) pain.12,13
7. Prostate cancer:
Capsaicin may play a role in suppressing prostate cancer cells.14
8. Chemo side effects:
Oral capsaicin can provide pain relief for oral mucositis in patients undergoing chemotherapy.15
Capsaicin may help fight obesity by making you feel fuller so you end up eating less.16,17
Using capsaicin topically
Topical capsaicin products to alleviate sore muscles and joints have become more common.17 The compound is now being used in creams, lotions, gels, nasal sprays and patches.
When using a capsaicin ointment, a slight burning or itching sensation is typical but temporary. Wash your hands thoroughly after applying any topical capsaicin product to avoid spreading the ointment to sensitive areas such as the eyes.
