The Rod of Asclepius symbolizes the healing arts by combining the serpent, which in shedding its skin is a symbol of rebirth and fertility, with the staff, a simple tool.
A similar symbol, Nehushtan, is mentioned in the Bible as having been used for healing of snakebite.
The Rod of Asclepius is frequently confused with the caduceus, which is a symbol of commerce associated with the god Hermes.
