For thousands of years it has been used as a colorant to stain human hair, nails or skin a bright fire-engine red color. In literature, this orange-red color is often referred to as “henna red”. The ancients combined henna with other natural colorants like indigo, iron oxide or lead salts in order to produce brown and black colors.

CULTIVATION: The henna plant is native to northern Africa, western and southern Asia, and northern Australasia, in semi-arid zones and tropical areas. It produces the most dye when grown in temperatures between 35 and 45 °C (95 and 113 °F). During the onset of precipitation intervals, the plant grows rapidly, putting out new shoots. Growth subsequently slows. The leaves gradually yellow and fall during prolonged dry or cool intervals. It does not thrive where minimum temperatures are below 11 °C (52 °F). Temperatures below 5 °C (41 °F) will kill the henna plant.
BENEFITS OF HENNA
Today people still use henna to color their hair. It is a natural coloring agent without the potential health hazards posed by the synthetic coal tar derivatives, many of which are potentially carcinogenic.
Furthermore, a henna treatment leaves the hair excellently conditioned, with added body and superb shine.
When using henna, the following procedure is used. The henna powder is first mixed with water to the consistency of a thick paste. This paste is then applied to the hair wherever coloration is desired. The longer this “henna pack” is left on the hair the more color is transferred. Heat can be used to further fasten the coloring. When the desired color is achieved, the henna paste is removed by washing and the process is complete.
Henna is one of the oldest cosmetics known, used as a dye to stain nails, hands, feet and hair. The art of staining patterns onto the skin is known as mehndi.
The dye is produced by mixing ground henna leaves with water, although tea leaves, indigo leaves, ground coffee beans or lemon juice are sometimes added to deepen the stain.
Among other compounds, the dying properties of henna have been attributed mainly to a compound called lawsone, which is found in the leaves (about 1% lawsone). Lawsone can bind to some proteins, such as keratin found in hair, which is why it is an effective dye for the body.
Other plants, such as indigo or the seed of the betel nut palm, may also be mixed with henna to change the shade of the dye. A combination of henna and indigo creates a black dye for hair.
Henna is also often used in cosmetic products as a hair conditioner and other preparations have included it for its reputed astringent, anti-dandruff and nail strengthening effects. Lawsone has also been used as a sunscreen.
Essential oil obtained from the flowers (mehndi oil) is used in Asian perfumery. In Pakistan, henna flowers are strewn upon oil seeds and are left in the sun for a few days, then old flowers are replaced by fresh, so the oil seeds eventually become permeated with the fragrance of henna flowers. This oil is used for grooming hair and is massaged onto the face and body as it is thought to improve the complexion and relieve aching muscles.

An infusion or decoction of the leaves is used for diarrhea and dysentery.
Extracts of henna leaves have been shown to act in a manner similar to ergot with respect to inducing uterine contractions. So it’s possible that extracts of the plant could induce menstruation and be effective emmanagogues.

Experimentally, a water extract of the leaves inhibited gram-positive and gram-negative bacteria. Antitumor activity in experiments with mice tends to support folkloric uses of henna as an anticancer agent.
