The thirteen tuber poisons and the signs of kālakūṭa

Tuber poisons are very dreadful and of thirteen kinds: kālakūṭa, karkaṭaka, sarṣapaka, kardamaka, vatsanābha, mūlaka, puṇḍarīka, mahāviṣa, sambhā (śṛṅgī), mustaka, hālāhala, pālaka and vairāṭaka, as known from the teaching of Mahāvīra. Each is to be identified by its own signs and then treated; kālakūṭa destroys the sense of touch and causes violent trembling. A footnote gives markaṭaka as a variant of karkaṭaka.
