Commercially available preparations of garlic have been reported to have beneficial effects on some of the risk factors associated with atherosclerosis.
Two review authors (RJ and JK) independently extracted data and assessed trial quality. One author (RJ) contacted investigators to obtain information needed for the review that could not be found in published reports. MAIN
RESULTS:
One eligible trial with 78 participants was found. Both men and women (aged 40 to 75) were included. The follow-up period was short, 12 weeks only.After twelve weeks of treatment, pain-free walking distance increased from 161 to 207 metres in the group receiving garlic and from 172 to 203 metres in the placebo group. This was not a statistically significant difference. There was no difference in change of systolic or diastolic blood pressure, heart rate, ankle and brachial pressures. No severe side effects were observed and nine patients taking garlic (28%) and four patients taking placebo (12%) complained of a noticeable garlicsmell.Three trials were excluded from the review because they did not include any clinical measurements.

CONCLUSIONS:
One small trial of short duration found no statistically significant effect of garlic on walking distance.
