Henna is a dye procured from a tree Lawsonia inermis whose leaves when dried and mixed with boiling water stain the skin with a mahogany colour.
The leaves of the tree are gathered green and are placed in the shade to dry gradually. The leaves are then pounded and sifted to obtain a very fine powder. The compound is kneaded to make a paste that is neither fluid nor thick. The henna is then covered and left to rest overnight.
