Indian snakeroot is a plant. The root is used to make medicine.
Indian snakeroot is used for mild high blood pressure, nervousness, trouble sleeping (insomnia), and mental disorders such as agitated psychosis and insanity. Indian snakeroot is also used for snake and reptile bites, fever, constipation, feverish intestinal diseases, liver ailments, achy joints (rheumatism), fluid retention (edema), epilepsy, and as a tonic for general debilities.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Indian snakeroot is POSSIBLY SAFE when a standardized extract is used under the supervision of a healthcare professional trained in its use. Standardized Indian snakeroot contains a set amount of medicine. The amount of reserpine and other chemicals in Indian snakeroot can vary from plant to plant. Since the reserpine and other chemicals in Indian snakeroot can be very toxic, the dose must be accurate and the side effects monitored by a trained healthcare professional. Side effects can range from mild to serious and include nasal congestion, stomach cramps, diarrhea, nausea, vomiting, loss of appetite, drowsiness, convulsions, Parkinson's-like symptoms, and coma. Indian snakeroot can slow reaction times and should not be used when driving or operating heavy machinery.
