Sugar cane extract same as placebo: study

CHICAGO (Reuters) - The dietary supplement policosanol, which is 
promoted as a natural way to reduce cholesterol, did no better than a 
placebo in a trial that contradicts some earlier studies, researchers 
said on Tuesday.
Made from the waxy coating on sugar cane and sometimes from beeswax, 
wheat germ and rice bran, policosanol was originally popular in Cuba, 
where a group of researchers has touted its benefits, the report 
published in the Journal of the American Medical Association said.
The supplement contains alcohols that are supposed to act on cholesterol 
metabolism in the liver in a different way than statins, the hugely 
popular class of cholesterol-lowering prescription drugs.
In the nine-month study, 143 patients with high cholesterol were given 
up to 80 milligrams of policosanol per day or a placebo, and no 
significant differences were found.
"Our results suggest that (policosanol) is devoid of clinically relevant 
lipoprotein-lowering properties," at least in the white patients 
studied, wrote study author Heiner Berthold of the University of 
Cologne, Germany.
"Still, more independent studies are required to counterbalance the vast 
body of available positive trials," he said, and to determine if the 
supplement might have some long-term impact on heart disease.
Among previous studies to show policosanol's benefits, researchers at 
the University Hospital Center in Zagreb, Croatia, found the supplement 
lowered blood cholesterol levels by a significant amount and raised 
levels of a protein contained in so-called good cholesterol in 70 patients.
