Bad Breath and Body Odor: Raw garlic is infamous for its pungent smell.
Allergic Reactions: Rare but possible, with symptoms like itching or skin rashes.

How to Use Garlic for Optimal Benefits

Consumption: Eating raw garlic maximizes its allicin content, a compound responsible for many health benefits. However, cooking garlic lightly can still preserve some of its nutrients.
Topical Use: Garlic paste can be applied to the skin to treat fungal infections, such as athlete’s foot.
Supplements: Aged garlic extract capsules are ideal for those who dislike garlic’s pungency or want a convenient option.

Tip: Crush or chop garlic and let it sit for 10 minutes before consuming or cooking. This process activates allicin, amplifying its health benefits.
