Synopsis

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

Cayenne (Capsicum annuum), known for its spicy heat due to the active compound capsaicin, has been traditionally used in herbal medicine to support sinus health and relieve congestion. Historical and folk remedies often cite cayenne as a sinus decongestant, with proponents suggesting that its pungency helps thin mucus and open nasal passages. The warming sensation induced by capsaicin is believed to stimulate secretions in the nose and sinuses, thus aiding in clearing blocked airways.

However, the scientific validation for these claims is limited. While some small clinical studies and anecdotal reports indicate that nasal sprays containing capsaicin may help reduce symptoms of non-allergic rhinitis and sinus congestion by desensitizing nasal nerves, the evidence is not robust or specifically directed at sinus infections or sinus health in general. Moreover, most research has focused on topical or intranasal applications rather than oral ingestion of cayenne.

Overall, while cayenne’s use for supporting the sinus system is primarily justified by tradition and folk medicine, there is only modest scientific investigation into its effectiveness, with a lack of large-scale, high-quality clinical trials. Therefore, the evidence rating is moderate-low (2 out of 5), reflecting primarily historical use and some preliminary, but not conclusive, scientific support.
