Studies made on aqueous root extract of Selayak Hitam, a plant alleged to possess abortifacient activity in pregnant mothers established that the extract is teratogenic and did in fact cause abortion in mice. It was also observed that the aqueous root extract is relatively toxic as judged by the number of deaths occuring following administration of the extract.
