In the fall season, leaves from the trees contribute to leaf mold allergies and/or sensitivities. Our sinuses drain (hopefully) but we can get inflammation in the back of our throats. A remedy to help get rid of the redness and higher bacteria counts in the back of the throat is to gargle with equal portions of mouthwash and hydrogen peroxide (1 tbsp each). Gargle, spit the foam out - do NOT rinse the foam out. The amount of foam is indicative of the oxygen released because the hydrogen peroxide is reacting to the anaerobic germs that can cause sore throats. If there is a lot of foam then gargle the next several nights and hopefully you will see a reduction. And hopefully you will not catch a bug!
