Curcuma zedoaria, zedoary, white turmeric or kentjur, (known as కచొరము kacōramu in Telugu) is the name for a perennial herb and member of the genus Curcuma, family Zingiberaceae. The plant is native to India and Indonesia but now naturalized in other places including the US State of Florida. It was introduced to Europe by Arabs around the sixth century, but its use as a spice in the West today is extremely rare, having been replaced by ginger.
