Synopsis

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

Cayenne pepper, which contains the active compound capsaicin, has a long history of traditional use for treating headaches, including sinus-related headaches. In folk and herbal medicine, cayenne is believed to help by stimulating circulation and acting as a counterirritant, distracting from deeper pain by causing mild irritation or warmth where it is applied. In the context of sinus headaches, cayenne has often been used in the form of nasal sprays or topical preparations intended to relieve congestion and reduce headache symptoms.

Scientific evidence supporting cayenne’s use for sinus headaches is limited but not entirely absent. Some small studies and clinical reports suggest that intranasal capsaicin can reduce the frequency and severity of cluster headaches and may help with certain types of chronic headache disorders, possibly by desensitizing the trigeminal nerve and reducing neurogenic inflammation. However, high-quality, large-scale studies focusing specifically on sinus headache relief are lacking. The evidence for its effectiveness in sinus headache is therefore considered weak to modest. Most recommendations for using cayenne for sinus headaches are based on traditional use and anecdotal reports rather than robust clinical validation.

In conclusion, while cayenne has a traditional basis for use in sinus headaches and some preliminary scientific interest, its efficacy for this specific indication remains insufficiently proven by modern research, warranting a moderate evidence rating.
