Century Dictionary and Cyclopedia

1. n. An annual herb, Chenopodium Quinoa, native in Peru, Chili, etc., and there much cultivated for its farinaceous seeds. These afford a meal which can be made into cakes, but not into leavened bread. A favorite preparation is a kind of broth or gruel called carapulque, prepared from these seeds and seasoned with red pepper, etc. The quinoa is somewhat grown in England, the seed being eaten by fowls, and the leaves used like spinach. The plant resembles some common species of goose-foot or pigweed. A variety having white seeds is the one yielding food; the red seeds of another variety are used in decoction as an application for sores and bruises, and their husk has emetic and antiperiodic properties. Also called petty-rice.
