Garlic is associated with which effect?

• A. Lowers BP
• B. Treats UTIs
• C. Lowers blood sugar
• D. Treats hair loss

Answer: (A)

Garlic’s well-supported effect in OTC and herbal contexts is its ability to modestly lower blood pressure. The sulfur-containing compounds in garlic, such as allicin, help relax blood vessels and improve blood flow, leading to vasodilation. Clinical studies and reviews show that regular garlic supplementation can produce small but meaningful reductions in both systolic and diastolic blood pressure, especially in people with hypertension or prehypertension. This makes blood pressure lowering the most consistently observed and clinically relevant effect among the options.

The other listed effects aren’t reliably demonstrated in standard practice. While garlic may have antimicrobial properties in the lab and some studies explore metabolic effects, the evidence isn’t strong enough to confidently claim UTIs treatment, blood sugar reduction, or hair loss treatment as established outcomes.
