I tried taking garlic capsules every day, twice a day, high strength. After three weeks I got a rash, it didn't hurt or sting, you could just see it, brain fog where I could not concentrate or think straight or remember much - very scary. Will continue to take it but much smaller doses. Now trying Apple Cider Vinegar and wild oil of oregano - this is for my sinuses and allergies which spread to ears and cause bad headaches sometimes.
