Ginger
Cooking Spice.
Ginger is a pungent herb commonly used as a cooking spice throughout the world. It is the rhizome of the perennial plant Zingiber officinale in the family Zingiberaceae. Ginger is on the FDAs generally recognized as safe list, though it does interact with some medications, including warfarin. Ginger is contraindicated in people suffering from gallstones as the herb promotes the release of bile from the gallbladder.
