I. INTRODUCTION
Garlic (Allium sativum) is cherished worldwide as part of a healthy diet, not only because of its savory characteristics but also for its perceived medicinal properties. It is fascinating to note that, historically, individuals who have not come in contact with each other have reached many of the same conclusions about the interrelationship between garlic and disease prevention [1, 2]; such similarities in belief emphasize that folk wisdom should not simply be ignored, since it may provide valuable clues for discovering truth.
