Diuretic, hypotensive, and hypocholesterolemic effects of Eclipta alba in mild hypertensive subjects: a pilot study

The combined effect of dried Eclipta alba leaf powder (3 g/day) in encapsulated form on blood pressure, diuresis, and lipid profile of 60 mildly hypertensive male subjects in the age group of 40-55 years was studied. The subjects were divided into two groups, i.e., a control (placebo) and the Eclipta group, and were given six capsules (500 mg each) per day in three equal doses for a period of 60 days. Clinical parameters, viz., blood pressure, urine volume, electrolytes (Na and K) in serum and urine, lipid profile, and plasma lipid peroxides, were analyzed before and after the feeding trials. The findings revealed that the Eclipta-supplemented group showed a marked reduction in mean arterial pressure by 15%, total cholesterol (17%), low-density lipoprotein fraction (24%), triglycerides (14%), very-low-density lipoprotein fraction (14%), and plasma lipid peroxides (18%). Results also revealed a remarkable increase in urine volume (34%), urine sodium (24%), serum vitamin C (17%), and serum tocopherols (23%) of the Eclipta group. In conclusion, it would appear that E. alba is diuretic, hypotensive, and hypocholesterolemic and helps in the alleviating oxidative stress-induced complications in hypertensives.
