Rauvolfia is a perennial undershrub widely distributed in India in the sub-Himalayan regions up to 1,000 metres (3,300 ft).
Chemical composition
Rauvolfia serpentina contains dozens of alkaloids of the indole alkaloid family, including ajmaline, ajmalicine, reserpine, and serpentine, among others.[5][8]
Research
A 2016 review found that reserpine reduced systolic blood pressure (SBP) by about 8 mmHg compared to placebo, and may be as effective at reducing SBP as other front-line hypertensive drugs, although more research is needed to determine a dose-specific safety profile.[9]
Potential adverse effects
R. serpentina may cause adverse effects by interacting with various prescription drugs[10] or via interference with mechanisms of mental depression or peptic ulcer.[10] The reserpine in R. serpentina is associated with diverse adverse effects, including vomiting, diarrhea, dizziness, headache, anxiety, or hypersensitivity reactions.[5]
