Psoriasis is a skin disease that affects various areas of the body, including the scalp, elbows and knees. Approximately 6 million Americans have been diagnosed with this condition, according to the University of Maryland Medical Center. Psoriatic plaques are inflamed and red, are covered by silvery scales, have red borders, and are itchy. Standard treatment includes anti-inflammatory agents and ultraviolet light therapy. Capsaicin is a natural supplement that may also improve symptoms of psoriasis, but talk to a health care provider before starting to use this supplement.
About Capsaicin
Capsaicin, or capsicum, is the key active ingredient from chili peppers. It is available as an over-the-counter and prescription ointment in various strengths. Its main action is to relieve pain by blocking nerve endings that transmit pain impulses. Capsaicin is used for several medical conditions including psoriasis, arthritis and nerve pains associated with shingles and diabetes, according to Drugs.com.
Research
Based on a systematic review of a variety of research studies, researchers from the University Medical Center Freiburg, located in Freiburg, Germany, evaluated various herbs and supplements for skin diseases. This review, published in 2010 in the "American Journal of Clinical Dermatology," indicates that capsaicin has potential to become standard treatment for psoriasis. However, more research is needed to assess long-term benefits and safety of capsaicin and other botanical supplements. UMMC also indicates that capsaicin over-the-counter cream may help reduce the pain, inflammation, redness and scaling associated with psoriasis. The main side effect is a short-term burning feeling of the area of the skin where the capsaicin cream is applied.
Adverse Reactions and Safety Issues
Beside a burning sensation, capsaicin may also cause high blood pressure. Prescription capsaicin, not an over-the-counter form, may actually cause itchiness and redness of the skin as well as high blood pressure, according to Drugs.com. This supplement may interact with a class of drugs called ACE inhibitors. The safety of capsaicin during pregnancy and lactation have not been fully assessed, thus it should not be used in these situations. Prescription capsaicin should not be used on the scalp and in children under 18 years of age.
Considerations
Consult a qualified health care provider to find out optimal dosage and strength of capsaicin cream for your condition. It appears that over-the-counter capsaicin has a safer profile than the prescription capsaicin. Other herbs, vitamins, omega-3 essential fatty acids and a special diet may also help psoriasis sufferers, notes UMMC. Capsaicin does not replace and should not be used to replace conventional medication prescribed for psoriasis.
