Cloves of garlic contain vitamins A, B and C and the volatile oil contains allium, which converts to allicin when the herb is crushed or sliced. On exposure to the air allicin converts to diallydisulphide, which is a powerful bactericide. Used daily, it contributes greatly to the functioning of the body as no other herb does. It is one of the most effective killers of bacteria and viruses, and so helps in the healing of a variety of ailments.
Garlic is an effective aid to healing when sliced and applied directly to the site of a bite or sting, relieving soreness and reducing the chances of it becoming infected. Raw garlic is prescribed by herbalists as a treatment for a wide range of bacterial and fungal infections, such as catarrh. It will also improve bad circulation - simply incorporate cloves of garlic regularly in your cooking. A few drops of garlic oil, warmed slightly, put onto a piece of cotton wool and placed just inside the opening to the ear will relieve earache. Garlic will also increase your overall resistance to colds and bronchial infections in general.
