More recently, it has been investigated for antimicrobial, antihypertensive, lipidlowering, fibrinolytic, antiplatelet, and cancer protective effects. Garlic oil has also been used.

Garlic has been widely promoted for use in the treatment of hyperlipidaemia. Several early placebo-controlled trials1,2 and meta-analyses3,4 showed that garlic significantly decreased total serum-cholesterol concentrations. However, more recent data suggest that the effect is at best modest5 or that there is no significant difference6-9 when compared with placebo.
