Most revered plant, as per Ethnopharmacological relevance, paste made from the leaves of Henna plant has been used since the Bronze Age to dye skin, hairs, and fingernails especially at the times of festivals. In recent times henna paste has been used for body art paintings and designs in western countries. Henna, Hina, Mehndi, Marudaani, Egyptian Privet, Inai, Hinai, notionally is known as a black dye prepared from the dried and powdered leaves of the henna tree. It is traditionally used in Islamic and Hindu cultures as a hair colouring and as a dye for decorating the nails or making temporary skin tattoos. Western world finds it more as the temporary body art of mehndi or "henna tattoo" resulting from the staining of the skin using dyes from the henna plant.Despite such widespread use in dyeing and body art painting, Henna extracts and constituents possess numerous biological activities including antioxidant, anti-inflammatory, antibacterial and anticancer bioactivities. An important plant with significant in vitro and in vivo biological activities.

We have examined use base and researched the chemistry and biological activities of Lawsone along with its analogues and metal complexes. Mainly ability of Lawsone to undergo the redox cycling and chelation of trace metal ions are partially responsible for most of its biological activities. The responsible pigment of Henna, amber, red colour is the 1,4-naphthoquinone Lawsone, constituting 1–2% of the leaves, which is achieved after application on Skin. More than 70 phenolic compounds have been isolated from various parts of the plants under phytochemistry actions. It is naphthoquinones, which include the dyeing principle lawsone, have been linked to the pharmacological activities. The terpene, β-ionone is largely responsible for the pungent odour of the essential oil isolated from the flowers. In addition to other volatile terpenes, some non-volatile terpenoids, a single sterol, two alkaloids and two dioxin derivatives have also been isolated from the plant.Our strength so far has been using alkaloids to meet with ph.7.0 to 8.0 as in Hair Colour needs than pure henna ph. Of 5.5 which creates cuticle shield needing high curing time of natural lawsone. Immense help of our Henna cousins of Cassia family offering biosimilar as polyphenols rich muddied in quinones as straight plant derivatives**. The optimum pH level thus derived helps to reduce cuticle damage.

Extraction procedures used and under trial by our team on continual improvement basis include infusion, percolation, Soxhlet extraction, superficial extraction, maceration, digestion, decoction, ultrasound-assisted, and microwave-assisted extractions.The Science Behind LawsoneWe have examined use base and researched the chemistry and biological activities of Lawsone along with its analogues and metal complexes.
