Caduceus Symbol - Meaning, History, and Medical Use #3047950 (License: Personal Use)

The caduceus features a central staff topped with wings and wrapped by two serpents in symmetric coils, originating from Greek mythology as the herald’s staff of Hermes. Though historically linked to commerce, negotiation, and alchemy, it became popular in U.S. military medicine in the 20th century and is now frequently-but erroneously-used to represent healthcare. In contrast, the Rod of Asclepius (a single serpent on a plain staff) is the authentic medical symbol.
