Indian snakeroot (Sarpagandha)- to Lower High Blood Pressure / Hypertension
Scientific name: Rauwolfia serpentina
Part used: root
Constituent that helps lower high blood pressure: Reserpine, an alkaloid substance with powerful sedative effect found in the root.
Although this herb is best known for treating
Reserpine works by significantly lowering catecholamines stores in adrenergic nerves and in the heart. This slows down the heart rate and helps open up capillaries and arterioles which in turn cause a reduction in blood pressure.
The powdered root of Rauwolfia serpentina contains not less than 0.15 percent of alkaloids calculated as reserpine. Studies conducted to determine the effect of R. serpentina root on blood pressure found that the reserpine in the herb root is effective in mild to moderate hypertension.
In a Cochrane review to investigate the dose related effect of reserpine on blood pressure, heart rate and withdrawals due to adverse events, the authors concluded that reserpine is effective in reducing systolic blood pressure approximately to the same degree as other first line anti-hypertensive drugs.
Dose: 1-2 gm of Sarpagandha powder once a day.
