Researchers find acupuncture equally effective for the treatment of hypertension as the drug nifedipine, a pharmaceutical medication used for the treatment of high blood pressure and angina. Nifedipine is a calcium channel blocker that relaxes the heart muscles and blood vessels. Researchers at the Jiaozuo Tongren Hospital compared the effects of acupuncture therapy with the administration of nifedipine for the immediate reduction of high blood pressure levels in patients with primary hypertension. In the Jiaozuo Tongren Hospital randomized-controlled clinical trial, both acupuncture and nifedipine successfully reduced blood pressure by 30 – 40 mmHg. 
The researchers determined that acupuncture and nifedipine provided different advantages for the management of hypertension. Data points measured immediate and short-term benefits of both therapies. At the 5, 10, 15, and 20 minute data points after treatment, nifedipine produced lower systolic and diastolic blood pressures. However, at the 30 and 60 minute data points after treatment, there was no statistical difference between the effects of acupuncture and nifedipine for both systolic and diastolic blood pressure management.
