Abstract Summary
Objective: This study investigates the effects of Ashwagandha (Withania somnifera) on lowering blood pressure in adults with mild hypertension.
Context: Ashwagandha, a renowned adaptogen, has been traditionally used in Ayurvedic medicine for stress management. Emerging evidence suggests that its calming effects may extend to cardiovascular health by reducing blood pressure. This study aims to evaluate the effectiveness of Ashwagandha supplementation in lowering systolic and diastolic blood pressure in adults diagnosed with mild hypertension.
Methods Used
Approach: A randomized, double-blind, placebo-controlled trial was conducted over 12 weeks with 120 participants aged 35-60 who had been diagnosed with mild hypertension (systolic BP between 130-139 mmHg, diastolic BP between 80-89 mmHg). Participants were divided into two groups: one group received 500 mg of Ashwagandha extract daily, while the control group received a placebo. Blood pressure readings were taken at the start, mid-point (6 weeks), and end of the study.
Data Collection: The primary outcome was the change in systolic and diastolic blood pressure, measured using a standard sphygmomanometer. Secondary measures included heart rate and perceived stress levels (assessed using the Perceived Stress Scale).
Researchers' Summary of Findings
Impact on Health: Participants in the Ashwagandha group showed a significant decrease in both systolic and diastolic blood pressure compared to the placebo group. On average, systolic blood pressure decreased by 12 mmHg, while diastolic pressure decreased by 8 mmHg in the Ashwagandha group. The placebo group showed minimal changes (3 mmHg systolic and 1 mmHg diastolic).
Health Implications: These findings suggest that Ashwagandha may be an effective natural supplement for reducing mild hypertension, particularly in individuals who also experience stress. Its dual action on stress reduction and blood pressure regulation makes it a promising intervention for managing cardiovascular risk factors.
