Eating Raw Garlic could lead to harm to your body but you'd have to eat a whole lot of raw garlic for it to be a real problem.
Side effects of eating raw garlic are bad breathe, diarrhea, vomiting, gas, heartburn and a burning sensation of your stomach or mouth.
Raw garlic applied directly to skin could also cause skin irritation as well.
Eating garlic in moderation is good for your health but avoid eating too much of it at one time.
