The Staff of Asclepius
(Æsclepius, Asklepios) [Personification of Medical or healing Art and its ideals]
Professional and patient centered organisations (such as the NZMA, in fact most medical Associations around the world including the World Health Organization) use the "correct" and traditional symbol of medicine, the staff of Asclepius with a single serpent encircling a staff, classically a rough-hewn knotty tree limb. Asclepius (an ancient Greek physician deified as the god of medicine) is traditionally depicted as a bearded man wearing a robe that leaves his chest uncovered and holding a staff with his sacred single serpent coiled around it, (example right) symbolizing renewal of youth as the serpent casts off its skin. The single serpent staff also appears on a Sumerian vase of c. 2000 B.C. representing the healing god Ningishita, the prototype of the Greek Asklepios. However, there is a more practical origin postulated which makes sense [See Dracunculus medinensis].
