I use fresh garlic as an antibiotic for earache and sinus infection. The antibiotic properties of garlic are a direct result of the allicin produced from raw, crushed garlic. This is destroyed by age and cooking - cooked garlic has virtually no antibiotic value. I crushed a fresh garlic clove, placed it in a handkerchief and squeezed a couple of drops in my son's ear, he was asleep in minutes with no pain in the morning. I've also sauteed noodles in olive oil & sprinkled fresh crushed garlic on it to address sinus problems.
Garlic for ear ache: one garlic tooth. heat not too hot. cut a piece from garlic. wrap in a cotton ball with vick 's vapor rub then insert in ear. Not both ears. in no time you'll feel better.
