The Caduceus is a symbol featuring two snakes entwined around a winged staff. It is often mistakenly associated with medicine and healthcare, although its origins are rooted in ancient mythology. The staff is linked to Hermes, the Greek messenger god, who was also the protector of merchants and travelers. In modern usage, the Caduceus is frequently seen in medical contexts, particularly in the United States. However, the true symbol of medicine is the Rod of Asclepius, which features a single snake and no wings. This distinction is important for understanding the historical and cultural significance of these symbols.
