Today world face one of the biggest problem is hypertension in adults. Hypertension, also known as high blood pressure, increases the risk for heart disease and stroke, two leading causes of death for people in the United States [1]. In the United States, about 77.9 million (1 out of every 3) adults have high blood pressure. A global brief on hypertension by WHO reported that, the prevalence of hypertension in adults aged 25 and above was about 40% around the world in 2008, rising from 600 million in 1980 to 1 billion in 2008 during the past 28 years [2]. Similarly, this prevalence among the adults aged 18 and above in China has risen from 18.8% in 2002 to 25.2% in 2015, presently, there are more than 200 million hypertensive patients in China [3]. Epidemiological studies show a steadily increasing trend in hypertension prevalence over the last 40 years, more in urban than in the rural areas. This is converse to findings reported from developed countries where there is a significant decrease in its prevalence.
