Henna, scientifically known as Lawsonia inermis, is an herb used historically as a natural colorant and possesses pharmaceutical significance due to its components, particularly lawsone, which provides dyeing ability and contributes to its anti-inflammatory, antipyretic, and analgesic properties.

Mehndi, also known as henna, is a traditional form of temporary body art created using a paste made from the powdered leaves of the Lawsonia inermis plant. Popular across South Asia, the Middle East, and North Africa, it is applied during weddings, Eid, and Diwali as a symbol of joy, beauty, and good luck.
