Cayenne pepper's bright red color signals its high content of beta-carotene or pro-vitamin A. Often called the anti-infection vitamin, vitamin A is essential for healthy epithelial tissues including the mucous membranes that line the nasal passages, lungs, intestinal tract and urinary tract and serve as the body's first line of defense against invading pathogens.
Capsaicin not only reduces pain, but its heat also stimulates secretions that help clear mucus from the body including mucus in the nose or lungs. Capsaicin is similar to a compound found in many cold remedies for breaking up congestion, except that capsaicin works much faster. A tea made with hot cayenne pepper very quickly stimulates the mucus membranes lining the nasal passages to drain, helping to relieve congestion and stuffiness. Next cold and flu season, give it a try!
