Sprinkling ground flaxseed over your meals can make a big impact on your blood pressure readings. In a 2013 study published in the journal Hypertension, participants with high blood pressure and peripheral artery disease ate 30 grams (about an ounce) of milled flaxseed daily. After six months, their systolic blood pressure (the top number) went down by 15 mm Hg, on average, and their diastolic blood pressure (the bottom number) dropped by 7 mm Hg.
Several Indian studies over the last few years have shown that Arjuna, in animals and in humans, reduces total cholesterol and increases HDL (“good” cholesterol). One study showed that this herb was as effective an antioxidant as vitamin E and that it reduced cholesterol in the human subjects quite substantially. Considering its benefit for cholesterol, it is not surprising that it lowers blood pressure; many cases of high blood pressure in the United States are caused by cholesterol accumulation in the arteries.
