The Indian Kudzu (Pueraria tuberosa DC.) is an important medicinal plant widely used in Indian and Chinese traditional systems of medicine. The present study is an attempt to evaluate effect of its tubers on blood pressure, coagulation parameters and antioxidant status in patients with stage 1 (primary) hypertension. In a long-term, single blinded, placebo controlled study; 15 patients with stage 1 hypertension (group 1), were administered 3 g P. tuberosa in two divided doses while another 15 patients (group II) were administered matched placebo for a period of twelve weeks. A significant fall of 25, 11 and 16 mmHg was observed in systolic (p < 0.001), diastolic (p < 0.05) and mean (p < 0.001) blood pressure, respectively at the end of the study. Along with blood pressure reduction, there was a significant (p < 0.01) reduction in plasma fibrinogen and significant enhancement of plasma fibrinolytic activity (p < 0.001) and serum total antioxidant status (p < 0.05). It was tolerated well without any untoward side effects.

Verma et al. (2012) conducted an RCT in Stage 1 (primary) hypertension (n=30). Pueraria tuberosa DC. (Indian Kudzu) vs. Matched placebo was evaluated on Blood pressure (systolic, diastolic, and mean) (p=<0.001). Pueraria tuberosa reduced systolic, diastolic, and mean blood pressure by 25, 11, and 16 mmHg at 12 weeks in stage 1 hypertension.
