Warnings on Garlic

Garlic has been associated with reducing high blood pressure. Yet, none of the 173 clinical trials conducted since 1900 has offered a clear conclusion on how it works.

At a recent National Institutes of Health meeting, Professor Eric Block, PhD, of the State University of New York at Albany, noted that garlic is highly complex and not easily replicated. According to Professor Block, ?People are throwing their money down the garbage hole by buying [garlic supplements] that aren?t properly made.?

Another researcher tested 30 types of garlic pills. Some broke down one-half hour after ingestion, suggesting that the active compound was immediately destroyed by stomach acid. Other pills took days to dissolve, meaning that the compound might not ever be absorbed.
