LAWSONIA INERMIS • Subkingdom: Tracheobionta • Superdivision: Spermatophyta • Division: Magnoliophyta • Class: Magnoliopsida • Subclass: Rosidae • Order: Myrtales • Family: Lythraceae • Genus: Lawsonia L • Species: Lawsonia Inermis L Origin and Geographical Distribution Lawsonia Inermis is native throughout the Middle East, North Africa and the Indian subcontinent. It flourishes in sunny positions in heavy soils that hold moisture well - though it will grow almost anywhere in these regions. These days it is also widely cultivated in China, The West Indies and Australia as well as in its native countries. Description Lawsonia Inermis is a heavily scented evergreen shrub-like tree. It grows up to 6 meters in height (20 feet) and has abundant branches. Its many leaves are narrow and pointed, and its pink and cream flowers are small, growing in clusters. When in fruit, tiny blue/black berries are produced. The leaves contain the active colouring ingredient ‘Lawsone’. Propagation Lawsonia Inermis does grow wild throughout its native countries, and is also a common tree found in gardens and villages. However these days it is mainly cultivated on a large scale as it is a valuable cash crop. It is a perennial plant, and with the exception of the initial year, it can be harvested twice a year in April/May and October/November. Initial yields are low, but increase to around 1,700kg per hectare, and up to 2,000kg per irrigated hectare. For a good crop with a high Lawsone content in the leaves a temperature of around 25 degrees C is required, henna grown in lower temperatures may look the same, but will be produce far inferior quality henna powder, with a poor colour content. It is also important to dry the leaves fast and out of direct sunlight, to retain the colouring properties. It is after all the lawsone content that drives the market for this valuable cash crop, local people have used henna powder, chiefly as a cosmetic for thousands of years, hence its dispersal throughout North Africa, The Middle East & the Indian Subcontinent. Biochemistry The Key biochemicals of Lawsonia Inermis are; Lawsone (2-hydroxy 1,4 - napthaquinone), Tannin, Behenic Acid, Arachidic Acid, Stearic Acid, Palmitic Acid, Oleic Acid, Linoleic Acid Scientific Name Preferred Scientific Name: Lawsonia Inermis L Other Scientific Names Lawsonia alba Lam.
