Lawsonia inermis, also known as hina, the henna tree, the mignonette tree, and the Egyptian privet, is a flowering plant and one of the only two species of the genus Lawsonia, with the other being Lawsonia odorata. It is the source of the dye henna used to dye skin, hair and fingernails, as well as fabrics including silk, wool and leather. Medicinal properties for the cure of renal lithiases, jaundice, wound healing; prevent skin inflammation. The bark is traditionally used in treatment of jaundice and enlargement of the spleen, renal calculus, leprosy and obstinate skin diseases. The species is named after the Scottish physician Isaac Lawson, a good friend of Linnaeus.
Borrowed from Arabic حِنَّاء (ḥinnāʾ), the name of the tree used to make the dye, probably from Middle Persian [script needed] (*hannāy-, “to smear, anoint”).
