A new research into the disease fighting properties of Garlic has turned up fresh evidence about its health benefits. Researchers from the University of Adelaide have found that an extract from the humble clove of garlic can help treat high blood pressure. The finding was reported in the latest edition of the scientific journal Maturitas. However, the researchers caution that according to their studies they did not observe similar health benefits from garlic that was consumed raw or cooked in meals. The benefits were only observed in an extract from aged garlic. The studies were carried out over a period of twelve weeks and involved fifty test subjects.
