Henna Lawsonia inermis

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 treat

Whole, unbroken henna leaves will not stain the skin. Henna will not stain skin until the lawsone molecules are made available (released) from the henna leaves. However, dried henna leaves will stain the skin if they are mashed into a paste. The lawsone will gradually migrate from the henna paste into the outer layer of the skin and bind to the proteins in it, creating a stain.
