Many people suffer from acute pulmonary hypertension, where blood pressure is selectively elevated in the lungs. The potentially lethal condition can make the right side of the heart work too hard and thus lead to heart failure. This particular form of high blood pressure might be prevented by a daily downing of two cloves of fresh garlic or its powdered equivalent, a new study in rats suggests.
Seven years ago, pharmacologist David D. Ku of the University of Alabama in Birmingham reported experiments showing that constituents of some garlic tablets could relax constricted blood vessels, just what is needed to alleviate pulmonary hypertension (see Garlic's Benefits: It's All in the Preparation). The tablets that were most effective had been prepared from fresh garlic or were labeled as likely to contain allicin. That
