Continuing on from last weeks post, I will be continuing my exploration into plant species within South Asia. This particular blog post will feature the otherwise ordinary shrub known for its highly pigmented dye, Lawsonia inermis.
Lawsonia inermis L., commonly referred to as Henna, is a tall shrub or small tree ranging in height from 1.8-7.6m tall. Native to Africa and South Asia, L. inermis thrives at high temperatures and cannot survive the milder climate (below 11°C) found within the UK. At 35-45°C is when the most dye, referred to as Lawsone or hannotannic acid, is produced. It is this dye that produces the dark red-orange pigment that Henna is known for.
Harvested leaves are ground into a fine powder and often mixed with a mild acidic liquid such as tea, lemon juice or lime juice to produce the paste used in the traditional practice of mehndi/mehendi. Mehndi is the art of piping the henna past onto the skin in beautifully intricate patterns often containing floral and geometric designs. Mehndi is typically applied in the nights before a wedding, with a tradition of hiding the groom’s name amongst the bride-to-be’s mehndi.
Aside from mehndi, henna is also used holistically in the Ayurveda practice of medicine. It is often mixed with essential oils and applied topically to treat headaches, stomach pains and burns as well as open wounds and fever. Henna can also be used as a form of sunblock. Henna would also be applied to colour the hooves, paws and tails of particularly favoured horses, donkeys and salukis.
