Blood Pressure Lowering Effect of Polyherbal Preparation Containing Allium Sativum, Belericae Fructus, Curcuma Aeruginosa, and Amomi Fructus on Rat Model of Hypertension

Objective: The study aimed to investigate the blood pressure lowering effect of the polyherbal preparation contains Allium sativum, Belericae fructus, Curcuma aeruginosa, and Amomi fructus in the animal model of hypertension. Methods: Deoxycorticosterone acetate uninephrectomy salt rat model was used to develop hypertension model. Hypertensive rats were divided into five groups that were no treatment (negative control group [NEG]), hydrochlorothiazide treatment, polyherbal preparation 63 mg/kg treatment (DOSE 1), polyherbal preparation 126 mg/kg treatment (DOSE 2), and polyherbal preparation 252 mg/kg treatment (DOSE 3). The treatment was started after hypertension developed and given for 3 weeks. Results: The result showed that the mean of systolic blood pressure in DOSE 2 group was significantly lower compared with those on NEG group (145.86 mmHg vs. 174.71 mmHg, p<0.05). Conclusion: Our study provides evidence to support the use of the polyherbal preparation containing A. sativum, B. fructus, C. aeruginosa, and A. fructus for lowering blood pressure.
