I've passed that stuff too. I've heard of garlic being antifungal and antibacterial. I really think that worms make you produce more yeast and they eat it. When they die you produce too much still but they don't eat it because they are dead. I have no proof and no research to back it up but it makes sense to me. I would just take probiotics and eat yogurt to try to balance your system. Garlic wont hurt anything.
