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 p
eripheral 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 +/-
8 5.0 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, spontane
ous thrombocyte aggregation, plasma viscosity, and cholesterol concent
ration also decreased significantly. Body weight was maintained. It is
quite interesting that the garlic-specific increase in walking distan
ce did not appear to occur until the 5th week of treatment, connected
with a simultaneous decrease in spontaneous thrombocyte aggregation. T
herefore, garlic may be an appropriate agent especially for the long-t
erm treatment of an incipient intermittent claudication.
