Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Garlic bulb (Allium sativum) has a long history of traditional use as a remedy for parasitic infections, including intestinal worms and other parasites. Ancient cultures such as the Egyptians, Greeks, Romans, and Chinese used garlic for a variety of ailments, including parasites. Traditional medical systems, including Ayurveda and Traditional Chinese Medicine, have recommended garlic for its antiparasitic properties for centuries.

From a scientific perspective, laboratory studies have demonstrated some antiparasitic effects of garlic extracts and its active compounds, such as allicin, against certain protozoa and helminths in vitro and in some animal models. However, clinical evidence in humans is limited and of low quality. Most studies are small, lack rigorous controls, or are anecdotal. Thus, while there is some mechanistic support for the traditional use of garlic against parasites, robust clinical trials are lacking.

Overall, the use of garlic bulb for general parasitic infections is primarily supported by traditional use, with some suggestive but not definitive scientific evidence. The strength of evidence is rated as 2 out of 5, reflecting historical use and preliminary laboratory findings, but insufficient high-quality clinical research to firmly validate its efficacy for this purpose in humans.
