I have purchased 3 bottles of oregano oil in order to heal my tooth cavities, something that turned out succesful. In about one week, i began to see the black spots on my teeth turn to white. I would recommend this product to anyone with the same situation. Thanks iherb.com for saving me from toxic fillings and painful dentist drills!
