Traditionally, cayenne pepper has been used to treat sore throats. It is said that water mixed with cayenne pepper can be used to gargle when you have a sore throat. Caution, cayenne pepper is very spicy.
When it comes to clearing up a sore throat, or any other issue that affects your respiratory system, elderberry might be the best choice. Elderberries contain active ingredients that can soothe inflammation and irritation and also act as an expectorant and clear out phlegm that can trap foreign agents in your glands.
