My research on garlic’s medicinal properties, on the other hand, shows a contrary picture. Let me summarize the evidence as I have noted:
The plant is effective in reducing high blood pressure, showing promise in reducing cardiovascular risk (Ackermann et al., 2001).
Garlic is useful in alleviating atherosclerosis (Berthold et al., 1998).
Borelli et al. (2007) performed a study that reveals adverse interactions of garlic with certain drugs. Isoniazid is used to treat tuberculosis and in birth control pills. The cyclosporine is given after an organ transplant. Blood-thinning medications could all be made less effective when patients take garlic supplements.
Dried garlic preparations (in doses as low as 600 mg per day) or as fresh, high allicin-yielding garlic (10–20 g per day) appear significantly to reduce total serum cholesterol over 1–3 months. (Silagy, C.,’ et al., 1994) The scientists further note that the reduction of HDL, though, was very slight.
Garlic is extensively used in Traditional Chinese Medicine. It is now extensively used as an OTC supplement in many parts of the world.
