According to a new study published in the journal, Annals of Allergy, Asthma & Immunology, chili peppers have a positive effect in alleviating symptoms such as nasal congestion, sinus pain, and sinus pressure. Scientists studied capsicum annum, the part of the chili pepper that produces the spicy sensation. When concentrated and used in spray form, capsicum annum was better than a placebo spray at alleviating non-allergic sinus congestion (congestion brought on by environmental elements such as weather and household chemicals).

This is a significant finding because currently doctors do not have good methods of treating non-allergic sinus congestion. Previously, scientists were unable to administer capsicum annum without the help of an anesthetic due to the intense heat, but now a form has been developed where it can be used continuously. While this is a significant advancement, don’t expect to see a capsicum annum based congestion reliever on your local drug store's shelves just yet.
