Atharva Veda 1.23

Against leprosy: with a healing herb

Night-born art thou, O herb, O dark, black, [and] dusky one; O colorer (rajanī), do thou color this leprous spot and what is pale (palitá).

The leprous spot, what is pale, do thou cause to disappear from hence, the speckled; let thine own color enter thee; make white things (çuklá) fly away.

Dusky is thy hiding-place, dusky thy station (āsthā́na); dusky art thou, O herb; make the speckled disappear from hence.

Of the bone-born leprous spot, and of the body-born that is in the skin, of that made by the spoiler (dū́ṣi)—by incantation have I made the white (çvetá) mark disappear.
