Garlic
Garlic has been used in cooking as well as medicinally in many cultures around the world for a long time. Because of its strong smell many prefer to take it as a supplement in tablet or capsule form rather than by eating the crushed cloves. It is credited with improving the health of the heart by reducing clot production and lowering cholesterol and blood pressure. It has also been found to be helpful in protecting against colds and other infections.
