Capsaicin Spray Clears Sinuses

CINCINNATIThe compound that gives chile peppers their heat can also help clear sinuses. In a new study published in the of Annals of Allergy, Asthma & Immunology, researchers from the University of Cincinnati found that a nasal spray containing Capsicum annum, an ingredient derived from chiles, proved to be a safe and effective treatement for non-allergic rhinitis. Capsicum annum contains capsaicin, which is the main component of chile peppers and produces a hot sensation.

For two weeks twice a day, subjects in the study administered either a intranasal preparation of Capsicum annum and Eucalyptol, or a placebo. Participants who used the nasal spray with Capsicum reported a faster onset of action or relief, on average within a minute of using the spray, than the group using the placebo.

This is the first controlled trial where capsaicin was able to be used on a continuous basis to control symptoms. It is considered a significant advance because, in previous trials, the ingredient was too hot to administer without anesthesia.
