The Randia dumetorum is a small thorny tree common in waste places. The fruit when ripe, looks like a small apple, and has a peculiar sweetish, sickly smell. It is described by Sanskrit writers, as the best or safest of emetics. In fact the ancient Hindus depended chiefly upon this drug for causing emesis. One ripe fruit is generally administered for this purpose. It is also used in combination with other medicines, as for example in the following prescription.
Pancha kashaya.3 Take of Justicia Adhatoda (vάsaka), Acorus Calamus (vachά), nim bark, leaves of Trichosantlies dioica (patola), and bark of Aglaia Roxburghiana (priyangu), equal parts, half a seer in all, water eight seers; boil them together till reduced to one-fourth. This decoction is given with the addition of the pulp of Randia dumetorum for causing emesis.
