For earaches and sore throats.... Put a few drops of tea tree oil in a capful of hydrogen peroxide(or baby or olive oil as your base) and pour in your ear. This will kill infection. Don't use straight tea tree oil in the ear it will burn. Also rub tea tree oil around the ear at the base and on the neck for sore throats! We've had ear infections and sore throats and have never taken antibiotics ever! This remedy has worked for several years!
