The seed of the silphium <http://en.wikipedia.org/wiki/Silphium> plant, used in ancient times as an herbal contraceptive <http://en.wikipedia.org/wiki/Herbal_contraceptive>,[4] <http://en.wikipedia.org/wiki/Heart_symbo.....linyXXII-3> has been suggested as the source of the heart symbol.[3] <http://en.wikipedia.org/wiki/Heart_symbo.....mcdonell-2>[5] <http://en.wikipedia.org/wiki/Heart_symbol#cite_note-4> The heart symbol could also be considered to depict features of the human female body, such as the female's buttocks <http://en.wikipedia.org/wiki/Buttocks>, pubic mound <http://en.wikipedia.org/wiki/Mons_pubis>, or spread vulva <http://en.wikipedia.org/wiki/Vulva>. The tantric symbol of the "Yoni <http://en.wikipedia.org/wiki/Yoni>" is another example of a heart-shaped abstraction of a woman's vulva.
