Root, leaf, fruit and flower poisons

Kṛtaka, araka, aśvamāra (kaner), guñjā and others hold poison in the root; viṣadalikā (viṣapatrikā), karambha and others in the leaves; kanaka (dhatūrā), tumbikā (bitter gourd) and others in the fruit, leaves and flowers. A footnote says the synonyms of kṛtaka and such poisons are found in no lexicon and cites commentators who say they are to be learned from the Kirāta and Śabara peoples of the Himalayan region.
