Garlic is one of the oldest known medicinal plants,
and it's been credited with fighting heart disease, lowering blood
pressure and helping to fight off colds.
It is nothing new and has been an established herb in India and China for 5000 years. When penicillan was discovered it took over from garlic as the antibiotic of choice. Though for obvious reasons nowadays it is worth rethinking that.
Garlic has been shown to lower choleserol levels by up to 12%; it has been shown to lower blood pressure by 1 - 5% and thus reducing the risk of stroke by 30 - 40% and lowering the risk of heart disease by 20 - 25%.
It is common practice to take garlic to prevent olds and flu.
However, many of the garlic supplements you buy in the High Street shops are of little to no value. Often the vital ingredients in the garlic have been removed in the extraction process or processed in such a way the the potential for absorption of the of the active ingredients is reduced so much that you may as well be taking a sugar pill.
These practitioner grade tablets are similar to raw garlic and care has been taken to preserve the vital ingredients and offer good absorption potential.
