A BBC news story reported that Allium sativum may have beneficial properties, such as preventing and fighting the common cold.
Allium sativum has been found to reduce platelet aggregation and hyperlipidaemia.
Garlic is also alleged to help regulate blood sugar levels. Regular and prolonged use of therapeutic amounts of aged garlic extracts lower blood homocysteine levels, and has shown to prevent some complications of diabetes mellitus. People taking insulin should not consume medicinal amounts of garlic without consulting a physician. In such applications, garlic must be fresh and uncooked, or the allicin will be lost.
Allium sativum may also possess cancer-fighting properties due to the presence of diallyl sulphide (DADs), believed to be an anticarcinogen.
Decocted garlic extracts that are left to set overnight are very effective in healing wounds. In 1858, Louis Pasteur observed garlic's antibacterial activity, and it was used as an antiseptic to prevent gangrene during World War I and World War II.
In modern naturopathy, garlic is used as a treatment for intestinal worms and other intestinal parasites, both orally and as an anal suppository. Garlic cloves are used as a remedy for infections (especially chest problems), digestive disorders, and fungal infections such as thrush. Whole cloves used as vaginal suppositories are sometimes used as a home remedy for Candidiasis (yeast infections).
Garlic supplementation in rats along with a high protein diet has been shown to boost testosterone levels.
