Research also suggests that garlic may have modest cardiovascular benefits. Some studies indicate that regular garlic consumption may help lower blood pressure slightly in certain individuals with hypertension. Other research has found that garlic may contribute to modest reductions in LDL (“bad”) cholesterol. These effects are generally small and should not replace prescribed medications or medical advice.
Garlic also has antimicrobial properties in laboratory studies. Scientists have found that allicin can inhibit the growth of certain bacteria, fungi, and viruses under controlled conditions. However, this does not mean that placing raw garlic directly on the skin or inside the ear will safely treat infections. In fact, inserting garlic into the ear may cause irritation, allergic reactions, burns, or even push earwax deeper into the ear canal, making problems worse.
