Allium compounds are derived from Allium sativum, or garlic, which is one of the most widely studied medicinal plants.

Raw whole cloves have similar effects.
Resveratrol is a new and very popular supplement currently recommended by nutritionally oriented physicians, including myself, as avery potent antioxidant that may have potential as an anticancer and cardioprotective compound..
Resveratrol is found in the skins of red grapes and is, therefore, a component of red wine. It is also found in purple grape juice, berries such as blueberries, cranberries, and raspberries, and in smaller amounts in peanuts. In the 1990s, the compound began to attract attention as an explanation of the so-called “French paradox,” namely the low incidence of heart disease among French people despite their diet high in saturated fats.
