HENNA (Lawsonia inermis, L. alba): Fragrant Eurasian, Australian & African privet shrub, leaves, bark, and root contain hennotannic acid.
Ground henna was mixed with indigo in 3200 BC Egypt to color hair a rich black, often mixed with indigo leaves for a very dark blue dye. Needs 5.5 pH to obtain a permanent dye. Middle Easterners and SE Asians mix henna powder with oils and scents to paint intricate temporary tattoo-like designs on the body. Henna was also used as a leather dye, a dye for beards, fingernail & tooth coloring, dyeing horse hooves and manes. Ground henna gives reddish-brown tones while henna extract is a more green tone.
