The effect of natural ACE inhibitors, diuretics and temperature changes on systolic blood pressure in humans

  • Author(s) / Creator(s)
  • Blood pressure is the pressure exerted by circulating blood upon the walls of blood vessels, and hypertension occurs when blood is forced through the arteries at an increased pressure. The aim of the study examines the relationship between blood pressure and blood viscosity, and to examine the effectiveness of lowering high blood pressures with natural, non-pharmaceutical treatments. Twelve subjects between the ages of 18 and 25 were selectively chosen for the fourteen day duration of the study. The subjects were divided into two groups, group A and B. Group A comprised of individuals who train more than 3 times a week, and Group B consists of individuals who train less than 3 times a month. The subjects in the study had their blood pressures determined after a variety of treatments including temperature (hot, cold and room temperature water), natural diuretics (lemon juice with warm water, parsley tea), natural ace inhibitors (pomegranate juice) and a cardiovascular fitness test (10 minute run on a spin bike at 50 rpm). Systolic blood pressure plays a role in returning heart rates back to a normal state quicker in normotensive subjects than in hypertensive. The results show that fit individuals (Group A) showed lower pulse rates and blood pressures as compared to less fit individuals (Group B) after a fitness test. Also, their pulse rates returned more quickly to the resting condition after exercise than in a less fit individual. Colder temperatures stimulated an increase in systolic blood pressure in normotensive subjects. The natural diuretic and ACE inhibitor treatment significantly lowered systolic readings in group B. Natural ACE inhibitors and diuretics were shown to be an effective, natural, non-pharmaceutical treatment on lowering systolic blood pressures in hypertensive subjects. The future goal of this study is to develop natural treatments and therapies to assist individuals with high blood pressure. Future aims of this study also seek to increase life expectancy and quality of life for patients with hypertension through the use of natural blood pressure lowering treatments.
