Zedoary is a plant. The underground stem (rhizome) is used to make medicine.

Traditional methods for preparing zedoary involve washing it with lots of water to remove most of the protein and water-soluble nutrients. The rinsing is also supposed to remove a poison that is yet to be identified.

Zedoary is used for stomach pain, loss of appetite, indigestion, as a mosquito repellant, and many other conditions.
