    I read online garlic is really good for you and will clear up a femal yeast infection. Although I still believe that part of it since it did clear it up. I was instructed to eat 3 raw cloves a day. After the 4th day I broke out in burns in my mouth 9 in total. I cannot stick my toungue out theres 2 on the very back sides of my toungue that crack if I move my toungue at all. 2 under my toungue on each side and 2 between my cheek and gum on the top and 2 on the sides of my tongue. And one just starting near my top k 9 its cracking everywhere. Garlic can cause serious mouth burns. It hurts so bad I might go to the ER tomorrow.
