CAUTION: Due to oxalate content, you should cook this plant before consumption. Some, myself included, feel that small amounts may be added atop salads, or consumed as a trailside nibble. garden.org tells us that it "can cause serious contact dermatitis in dogs, especially the small, lower to the ground toy breeds." This is probably their general warning concerning species of Commelinaceae.

"Used locally in the treatment of asthma, leprosy and piles. Root paste wit goat milk is prescribed orally to cure asthma. Whole plant paste with common salt is applied on the affected area t cure leprosy (Panda and Misra, 2011)."  The “herb is cooked in oil employed in the treatment of leprosy.”

It is also listed as a medicinal plant in China in a publication by the Journal of Ethnobiology and Ethnomedicine, China.
