It is a sweet, cooling, nourishing tuber used in wasting and debility, and it appears in Mahamash Tel and Maha Narayan Tel in this catalogue.

Uses & benefits
Given in emaciation, weakness and convalescence, and as a Vrishya and Brimhana drug within the classical Rasayana and Vata preparations. Used externally in some formulations for swelling.
