Millettia is a genus of legume in the Fabaceae family. It consists of about 150 species, which are distributed in the tropical and subtropical regions of the world.
In 1834, in Prodromus Florae Peninsulae Indiae Orientalis Robert Wight and George Arnott Walker-Arnott describe Millettia as:
Calyx cup-shaped, lobed or slightly toothed. Corolla papilionaceous: vexillum recurved, broad, emarginate, glabrous or silky on the back. Stamens diadelphous (9 and 1), the tenth quite distinct. Legume flat, elliptic or lanceolate, pointed, coriaceous, thick margined, wingless indehiscent, 1-2 seeded: valves closely cohering with each other all round the seeds and between them. Twining or arboreous. Leaves very large, unequally pinnated: leaflets opposite, with a setaceous partial stipule at the base of each partial petiole. Racemes axillary, more or less branched and compound. Flowers pretty large, purplish, pedicelled on shortish diverging partial peduncles.
Long known to residents of the Indies, China, and Africa, this species has had many traditional names. One of the oldest references in traditional Chinese medicine is in Bencao Gangmu Shiyi ("Supplement to Compendium of Materia Medica") where is called jixueteng. The Chinese name literally translates to "stem of chicken's blood" which refers to the red resin present in the stems of several climbing legume shrubs.
