In pharmacology, reserpine is "an alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool..."
Reserpine was a component of combination therapy in several major trials of treating hypertension: the Hypertension Detection and Follow-Up Program (HDFP), Multiple Risk Factor Intervention Trial (MRFIT), Veterans Administrative Cooperative Study Group in Anti-hypertensive Agents, and the Systolic Hypertension in the Elderly Program (SHEP).
In a review of 691 patients in seven studies, McMahon found that 5% of patients discontinued reserpine because of adverse effects. 
American Geriatrics Society 2012 Beers Criteria Update Expert Panel recommends avoiding the use of reserpine (> 0.1 mg/d); however, their basis for this recommendation is not stated.
