c. 1850 BC First Contraceptives Made of Honey and Crocodile Dung
Egyptian texts are the first known record of suppository contraceptives. These texts describe the suppositories as being made from honey and crocodile dung (just imagine the smell!) The recipes for these methods were buried with Egyptian dead, so they wouldn't get pregnant in the afterlife.
300 years later in Egypt, pregnancy prevention methods had progressed to using tampon-shaped pieces of cotton soaked in fermented plant juice.
