Henna/Mehndi is an ancient form of body adornment worn by many
East Indian and Middle Eastern women. Although it is mostly used
for wedding ceremonies, henna has gained popularity worldwide as a
"temporary tattoo" because the designs only stay on the skin for
about two weeks to one month. Henna is painless, safe and natural
and can be used for hair as a natural dye. The henna plant is
crushed into powder and mixed with water, lime or lemon juice,
coffee or tea, and oil.
