The garlic thing is way off subject....but,
You have an interesting reaction to garlic, you are the first person that I know who gets ill from trace amounts of garlic. Have you done any testing on sulphur related things to see if you're sensitive or allergic to sulpher? Garlic maybe dangerous to you but not to others.
Let's face it, if it wasn't for garlic, none of us would be here because it was one the top antibiotic, antifungal substances used by our ancestors and still is world-wide.
