    Garlic may improve resistance to infections. Garlic appears to be effective against many kinds of microbes that cause infections. Allicin, one of the main biologically active compounds of garlic, is an antibiotic. At least against one bacterial species, allicin is more potent than penicillin.

    In the test tube, extracts of allicin can disable infection-causing amoebas by inhibiting key processes that many microbes need to cause infections.

    Test-tube studies show garlic extracts to be protective of tissue against certain viruses. One study found that the garlic compounds ajoene and allicin were the most effective ingredients of garlic extracts against herpes simplex, common cold and a number of other viruses.

    Garlic may have some infection-fighting capability. In laboratory dishes, researchers have seen garlic work against bacteria, viruses, and fungi. Although this is promising, there haven't been enough well-designed human studies conducted to know whether this translates into human benefits. One study that looked at southern European populations found an association between the frequency of consumption of garlic and onions and a lower risk of some common cancers. Until more is known, however, it's too early to recommend garlic as a way of treating or preventing infections or controlling cancer.
