Dravyanāmakara Nighaṇṭu, is an unpublished Nighaṇṭu (lexicon) of Ayurveda authored by the eminent Bhīṣma Vaidya and critically edited and commented upon by the legendary Ayurveda scholar, Vd. S.D. Kamat. The Dravyanāmakara Nighaṇṭu is a remarkable work that serves as an appendix to the Dhanvantari Nighaṇṭu, specifically dedicated to the study of homonyms of plant and drug names. With 182 verses and two additional colophon verses, this text offers critical insights into the study of homonyms, a subject of immense importance to scholars and practitioners of Dravyaguṇa, Rasaśāstra, Bhaiṣajya Kalpanā, and related disciplines. While the homonyms chapter is included in prose form in the published edition of the Dhanvantari Nighaṇṭu (by Ānandāśrama, Pune), this standalone publication enriches the study and understanding of this vital aspect of Ayurvedic pharmacology.
