Garlic reduces TC to a modest extent , an effect driven mostly by the modest reductions in TAG , without appreciable LDL lowering or HDL elevation .
Higher baseline line TC levels and the use of dietary modification may alter the effect of garlic on these parameters .
In order to determine the impact of  garlic on total cholesterol ( TC ) , TAG levels , as well as LDL and HDL  , and establish if any variables have an impact on the magnitude of this effect , a meta- analysis was conducted .
Effects of garlic coated tablets in peripheral arterial occlusive disease
Summary For the first time , a weak clinical efficacy of a 12-week therapy with garlic powder ( daily dose , 800 mg ) is demonstrated in patients with peripheral arterial occlusive disease stage II . The increase in walking distance in the verum group by 46 m ( from 161.0 ± 65.1 to 207.1 ± 85.0 m ) was significantly higher ( P<0.05 ) than in the placebo group ( by 31 m , from 172.0 ± 60.9 to 203.1 ± 72.8 ) . Both groups received physical therapy twice a week . The diastolic blood pressure , spontaneous thrombocyte aggregation , plasma viscosity , and cholesterol concentration also decreased significantly . Body weight was maintained . It is quite interesting that the garlic-specific increase in walking distance did not appear to occur until the 5th week of treatment , connected with a simultaneous decrease in spontaneous thrombocyte aggregation . Therefore , garlic may be an appropriate agent especially for the long-term treatment of an incipient intermittent claudication
