The tribal inhabitants of southern and eastern Bihar take the powdered roots orally as an antidote to snake venom. Extracts of the roots of Sarpagandha plant are valued for treatment of intestinal disorders, particularly diarrhoea and dysentery, and also as an anthelmintic.
The extract of Sarpagandha blended with other plant extracts are used for treating cholera, colic and fever. A decoction of the root is believed to stimulate uterine contractions and is recommended for use in problematic situations in childbirth.
