1. INTRODUCTION: Hypertension is an emerging global threat to human health. It is significantly contributing to mortality and morbidity [1]. It is a chronic condition in which elevated blood pressure is observed in arteries [2]. It is also known as Essential hypertension (EH). Blood pressure is expressed in terms of systolic and diastolic pressure. Systolic blood pressure is defined as the pressure in blood vessels when heartbeats while diastolic blood pressure is defined as the pressure in blood vessels when the heart rests between the beats. In hypertensive condition, systolic blood pressure is ≥ 140mmHg and diastolic blood pressure are ≥ 90mmHg [3]. Blood pressure normally falls and rises throughout the day, but if it stays high for a long time it can damage the heart and cause serious health problems e.g. brain haemorrhage. There are four stages of hypertension named as Pre-hypertension, Mild hypertension, Moderate hypertension and Severe hypertension. It is a common disorder that ...

It is anticipated that by 2025, the predominance of hypertension(HTN) will increase by 60% to a sum of 1.56 billion overall recommending that HTN remains a significant general medical issue. Hypertension (or HTN) or hypertension is characterized as abnormally high arterial blood pressure. Blood pressure is the force exerted by circling blood against the wall of the body's arteries, the significant veins in the body. Hypertension is when pulse rate is excessively high. Blood pressure is composed as two numbers. Firstly (systolic) number represents the pressure in blood vessels when the heart contracts or beats. The second (diastolic) number shows the vessels pressure when the heart rests between beats. As per the Joint National Committee 7 (JNC7) , typical BP is a systolic BP<120 mmHg and diastolic BP<80 mm Hg. Hypertension is characterized as systolic BP level of ≥140 mmHg or potentially diastolic BP level ≥ 90 mmHg. According to WHO (world health organization) ...
