Indians used a variety of birth control methods since ancient times, including a potion made of powdered palm leaf and red chalk, as well as pessaries made of honey, ghee, rock salt or the seeds of the palasa tree. A variety of birth control prescriptions, mainly made up of herbs and other plants, are listed in the 12th century Ratirahasya ("Secrets of Love") and the Ananga Ranga ("The Stage of the God of Love").[8]
