Some people experience sleeplessness, headaches or an upset stomach after eating garlic, but “garlic breath” is the most common side effect:-S:-$. This potent odor occurs when allicin is broken down in the stomach, absorbed into the lungs, and released from the body through the mouth and skin. Human noses are very sensitive to the smell, but mint or parsley can help mask it. The “stinking rose” many not make us smell sweet, but eating garlic can still make our health “come up roses!”:)>-
