Garlic has been used medicinally for a long time, most notably for its cardiovascular, anticancer, and antibacterial qualities. The active components in the garlic plant’s root bulb appear to be sulfur compounds, especially allicin. Studies have shown that it has significant but minor lipid-lowering and antiplatelet action. There isn’t always a significant drop in blood pressure. Antineoplastic activity is supported by some evidence, however clinical antimicrobial action is not. The majority of side effects are minor and infrequent. Garlic appears to have little effect on medication metabolism, however anticoagulant patients should exercise caution. Garlic in excessive doses should be avoided seven to ten days before surgery since it can extend bleeding duration.
