No, there is no scientific proof that garlic can widen blood vessels or lower blood pressure significantly.

No, there is no scientific study confirming that garlic can treat acne. In fact, applying garlic directly to the skin may cause irritation rather than help with breakouts.

Maybe. Garlic contains sulfur-based compounds that might support the immune system, but research has yet to confirm any definitive effect.
