How Henna (Mehndi) is Made
Use of mehndi is a part of several cultures. It is more
common in Middle-East and South-Asia. Mehndi or
henna is prepared from leaves of a plant called henna.
To prepare henna powder the leaves are first dried and then ground.
Grinding leaves ensures release of a substance called "lawsone".
Lawsone has the ability to form bonds with skin and stay there for a considerable time.
Crushed leaves are then dried to eliminate the moisture so that it is preserved for a longer time.
Leftover substance is the "henna powder".
