Two ancient symbols are often associated with medicine: the Rod of Asclepius and the Caduceus. The Rod of Asclepius, a single serpent entwined around a staff, comes from Greek mythology. Asclepius, the god of healing, was linked with snakes, which symbolized rejuvenation and renewal because of their ability to shed skin. This emblem has been used in medical contexts since classical antiquity and is regarded as the most authentic and appropriate symbol for healthcare and healing professions.
The Caduceus, on the other hand, features a winged staff with two serpents. It was carried by Hermes, the Greek messenger god associated with commerce, negotiation, and travel; not medicine. Its association with healthcare arose in the United States, especially after the U.S. Army Medical Corps adopted it in 1902, apparently due to confusion with the Rod of Asclepius.
While the Caduceus has become widespread, the Rod of Asclepius better represents the values of medicine: healing, knowledge, and the care of the sick. The Caduceus remains a symbol of trade and communication, whereas the Rod of Asclepius stands firmly as the true emblem of medicine. Surveys show that only about 6% of doctors recognize the Rod of Asclepius as the authentic medical symbol, while the Caduceus remains dominant due to its widespread modern usage.
