caduceus

This tag is used for the caduceus (symbol) (☤), Hermes' staff with two snakes spiraling up it. It is sometimes confused with the Rod of Asclepius.

Staff with two sculptured snakes entwined along its length (or just near the 'head'). Often surmounted with wings.
Traditionally associated with commerce and negotiation, as it is the herald staff of Hermes, the herald and messenger of the Greek Gods.
Sometimes used as an astrological symbol for the planet Mercury.
Sometimes used as an alchemical symbol for the elemental metal mercury.
May be carried by heralds.
More often depicted being carried by healers, due to confusion with the Rod of Asclepius.
Often also used in iconography for medical-related professions, again due to confusion with the Rod of Asclepius.
