Etymology: Emodin takes its name from a plant rather than a person or a place of coinage: the Latin name "Rheum emodi" is a synonym for Himalayan rhubarb, Rheum australe, and the compound was named after that species. The "-in" ending is the standard chemists' suffix used for many isolated plant substances, so the word simply reads as "the substance of Rheum emodi." The compound is a natural anthraquinone, which is why it is yellow-orange and crystalline, and it was obtained from the rhizomes and roots of rhubarb-family plants. Its laxative effect is the reason rhubarb roots have long been used in traditional medicine, and emodin is one of the compounds credited with that action.
