Hypertension :: Active ingredient in common Chinese herb shown to reduce hypertension
Some 50 million Americans have hypertension, that is, blood pressure measuring above the normal range (less than 120/80 mmHg). If untreated, it can lead to heart attacks, strokes, or kidney disease. Lifestyle changes are the first-stage treatment for the disease, but if they fail, medications are prescribed. In a soon-to-be-released study using an animal model, scientists have found that tanshinone IIA, an active ingredient of danshen, reduces blood pressure.
