Lawsonia inermis, commonly known as henna, is a flowering plant native to North Africa and the Middle East. It is best known for its leaves, which contain a natural dye used for body art and hair coloring. The plant thrives in hot, dry climates and can grow up to 6-10 feet tall. The leaves of Lawsonia inermis are dried and ground into a fine powder, which can be mixed with water to create a paste. This paste is applied to the skin or hair, producing a reddish-brown stain. Henna has been used for centuries in various cultures for decorative and ceremonial purposes.
