"Be careful guys with raw garlic. Once I chewed up just one half of one clove and swished it in my mouth with water, and it burned my cheeks and gums it was so powerful. I take it real easy now and make sure I don't swallow too much either - I don't want to burn up my insides!"

Imo the easiest way to tolerate raw garlic is to cut a clove(section) of it into small pieces after a large meal, chew each piece carefully, and swallow each piece separately with plenty water. Eating raw garlic on an empty stomach, or in large chunks and without chewing it well and without enough water could be very irritating to the digestive tract.
