Which of the following effects does garlic have on the body?

Garlic is known for its various health benefits, one of which is its ability to inhibit platelet aggregation. This means that garlic can help prevent blood cells, known as platelets, from clumping together, which is critical for reducing the risk of thrombosis and cardiovascular diseases. The active compounds in garlic, such as allicin, have antiplatelet properties that contribute to this effect. By reducing platelet aggregation, garlic may play a role in improving overall cardiovascular health.

In contrast, although garlic has been studied for its potential health benefits, it is not primarily recognized for enhancing memory or promoting sleep, nor is it the most significant factor in immune enhancement compared to other nutrients and lifestyle choices. This distinction solidifies the understanding of garlic's primarily recognized effect concerning cardiovascular health.
