Indications: Garlic is among the few herbs that have a universal usage and recognition. Its daily usage aids and supports the body in ways that no other herb does. It is one of the most effective anti-microbial plants available, acting on bacteria, viruses and alimentary parasites. The volatile oil is an effective agent and as it is largely excreted via the lungs, it is used in infections of this system such as chronic bronchitis, respiratory catarrh, recurrent colds and influenza. It may be helpful in the treatment of whooping cough and as part of a broader approach to bronchitic asthma. In general it may be used as a preventative for most infectious conditions, digestive as well as respiratory. For the digestive tract it has been found that Garlic will support the development of the natural bacterial flora whilst killing pathogenic organisms. In addition to these amazing properties, Garlic have an international reputation for lowering both blood pressure, blood cholesterol levels and generally improving the health of the cardio-vascular system. A recent study was conducted on two groups, one consisting of 20 healthy volunteers who were fed Garlic for 6 months and the other of 62 patients with coronary heart disease and raised serum cholesterol. Beneficially changes were found in all involved and reached a peak at the end of 8 months. The improvement in cholesterol levels persisted throughout the 2 months of clinical follow-up. The clinicians concluded that the essential oil of Garlic possessed a distinct hypolipidemic, or fat reducing, action in both healthy people and patients with coronary heart disease. Garlic should be thought of as a basic food that will augment the body's health and protect it in general. It has been used externally for the treatment of ringworm and threadworm.
