Abstract

Ethnomedicinal studies of Santhal Pargana (Jharkhand) reveal that eleven plant species belonging to altogether different genera of Apocynaceae are used by Santhal and Paharia tribes of the division in the treatment of diabetes, dysentery, eye troubles, indigestion, jaundice, malarial fever, skin diseases, stomachache, toothache, etc. The useful species for primary health care of these tribes are Allamanda cathartica L., Alstonia scholaris (L.) R.Br., Carissa spinarum L., Catharanthus roseus (L.) G. Don, Holarrhena pubescens (Buch. – Ham.) Wall. ex G. Don, Ichnocarpus frutescens (L.) R.Br., Nerium indicum Mill., Plumeria acuminata Ait., Rauvolfia serpentina (L.) Benth. ex Kurz, Thevetia peruviana (Pers.) Mill. and Vallaris solanacea (Roth) Kuntze. Unfortunately these valuable natural resources are becoming rare and threatened mainly due to their over exploitation, improper collection, trade of plant parts, habitat destruction and invasion of exotic weeds in the region. The rare and threatened taxa of medicinal value need urgent ex-situ conservation.
