Capsaicin mouth washes and nasal sprays are prescribed for toothache, bronchitis, asthma, and migraine headaches. The nasal sprays stop chronic runny noses and sneezing and reduce congestion. Capsaicin aids digestion and appetite, seems to lower blood sugar and cholesterol and reduces blood clotting. Capsaicin creams for topical application as pain relievers are available as over-the-counter drugs, but they are expensive.
