Mucus and Coughing

Capsaicin produces a temporary but significant expulsion of accumulated sinus mucus. The combined stimulation and desensitization from capsaicin helps open blocked sinuses and improve drainage pathways. Research supports nasal spray application of capsaicin for purging mucus, opening sinuses, and reducing nasal hyper-reactivity. Capsaicin actively drives mucus out of the sinuses by stimulating drainage rather than suppressing mucus production. Coughing expels infected mucus from the lungs and airways. Mucus physically traps and transports viruses out of the respiratory tract. Suppressing cough and mucus responses keeps the virus inside tissues longer and prolongs illness. Supporting productive coughing and mucus drainage is beneficial; suppressing these responses is harmful.
