Research

Invaluable remedy: Well over 1,000 research papers have been published on the medicinal effects of garlic. They show that it helps to lower raised blood fat levels, including cholesterol, to keep the blood thin and protect against blood clots, to lower raised blood pressure, to lower raised blood-sugar levels, and to have antibiotic activity.

Unknown action: While it is understood that when the fresh clove is crushed, alliin is broken down by alliinase into allicin (which has strong antiseptic activity), authorities still disagree on precisely how garlic achieves its medicinal effects. Nevertheless, research indicates that it is best to crush garlic cloves, and then to wait 10 minutes before using it in food or as medicine. This allows sufficient time for allicin to form.
