Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Cayenne pepper (Capsicum annuum) has a long history of traditional use in supporting the mucus membranes of the respiratory and digestive tracts. In various herbal medicine systems, particularly in traditional Chinese medicine and Native American healing practices, cayenne has been used to stimulate secretions in the mouth, nose, and throat, which is believed to help clear mucus and soothe irritated membranes. The primary active compound, capsaicin, is known to increase local blood flow and may stimulate mucus production as a protective response.

While there is some preliminary scientific evidence for capsaicin’s ability to stimulate mucus secretion and promote mucociliary clearance, especially in the respiratory tract, the evidence is not robust or specific enough to justify strong scientific claims. Most clinical studies have focused on capsaicin’s pain-relieving properties or metabolic effects. Thus, the rating reflects that most support for cayenne’s use for mucus membranes comes from tradition rather than rigorous scientific validation. In summary, cayenne pepper is traditionally used to support the mucus membranes, but current scientific evidence is limited and does not strongly support this use.
