In 2007, George Bakris, the world expert on hypertension, published a study with a team of researchers in the Human Journal of Hypertension showing that one upper cervical chiropractic adjustment had the same effect as two blood pressure-lowering drugs. Also, the effects of just one adjustment lasted more than six months. Compared to the placebo-treated patients, those who got the real procedure saw an average 14 mm Hg greater drop in systolic blood pressure (the top number in a blood pressure count) and an average 8 mm Hg greater drop in diastolic blood pressure (the bottom blood pressure number).

Other studies have shown similar findings with hypotensive patients. Chiropractic care raised their low blood pressure to normal levels. This highlights the body’s ability to create a homeostatic balanced environment once vertebral subluxations are removed.
