Rauvolfia, particularly the species Rauvolfia serpentina (Indian snakeroot), has a documented history of scientific use in the management of psychiatric conditions, including schizophrenia. The primary active compound, reserpine, was first isolated from Rauvolfia in the 1950s and became one of the earliest antipsychotic agents used in Western medicine. Reserpine functions by irreversibly blocking the vesicular monoamine transporter (VMAT), leading to the depletion of monoamine neurotransmitters (dopamine, norepinephrine, and serotonin) in the brain. Since an overactivity of dopaminergic pathways is implicated in the pathophysiology of schizophrenia, reserpine was found to reduce psychotic symptoms in some patients. However, its use declined due to significant side effects, including profound depression, parkinsonism, and hypotension, as well as the development of safer and more effective antipsychotic drugs (e.g., chlorpromazine, haloperidol). Although the evidence for efficacy is moderate and based on early clinical trials and historical medical practice, reserpine’s use in schizophrenia represents a scientifically validated—albeit now largely obsolete—approach. The World Health Organization and several pharmacopoeias historically included Rauvolfia preparations for psychiatric indications. That said, Rauvolfia or its extracts are rarely used for schizophrenia in modern clinical practice due to safety concerns and the advent of better alternatives.
