Indigofera tinctoria [2], also called true indigo, is a species of plant from the bean family that was one of the original sources of indigo dye. Description [ edit ]
Indigo is a natural dye extracted from the leaves of some plants of the Indigofera genus, in particular Indigofera tinctoria. Dye-bearing Indigofera plants were commonly grown and used throughout the world, particularly in Asia, with the production of indigo dyestuff economically important due to the historical rarity of other blue dyestuffs.

The chemical aniline, from which many important dyes are derived, was first synthesized from Indigofera suffruticosa (syn. Indigofera anil, whence the name aniline). In Indonesia, the Sundanese use Indigofera tinctoria (known locally as tarum or nila) as dye for batik. Marco Polo was the first to report on the preparation of indigo in India.
In the Philippines, blue to indigo colors were also obtained from Indigofera tinctoria and related species, known under common names including tarum, dagum, tayum. [27] In Central and South America, the important blue dyes were Añil (Indigofera suffruticosa) and Natal indigo (Indigofera arrecta). [45]
