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 .
Hypertension and hyperlipidaemia: garlic helps in mild cases.
Forty-seven non-hospitalised patients with mild hypertension took part in a r and omised , placebo-controlled , double-blind trial conducted by 11 general practitioners . The patients who were admitted had diastolic blood pressures between 95 and 104 mmHg after a two-week acclimatization phase . The patients then took either a preparation of garlic powder ( Kwai ) or a placebo of identical appearance for 12 weeks . Blood pressure and plasma lipids were monitored during treatment after four , eight and 12 weeks . Significant differences between the placebo and the drug group were found during the course of therapy . For example , the supine diastolic blood pressure in the group having garlic treatment fell from 102 to 91 mmHg after eight weeks ( p less than 0.05 ) and to 89 mmHg after 12 weeks ( p less than 0.01 ) . The serum cholesterol and triglycerides were also significantly reduced after eight and 12 weeks of treatment . In the placebo group , on the other h and , no significant changes occurred
