Caduceus vs. Rod of Asclepius

Commerce

Medicine

The two symbols to the left have very different meanings! If you have a medically oriented organization, use the symbol on the right!

The symbol on the far left is the Caduceus, a rod with wings and two snakes wrapped around it. It is the symbol for the ancient Greek god Hermes. Hermes is known for being a messenger of the gods, guide to the dead and protector of merchants, shepherds, gamblers, liars, and thieves. The Caduceus is generally used today as a symbol of commerce.

The symbol to the right is the Rod of Asclepius. It is a rod with one snake wrapped around it. It is the symbol for the ancient Greek god Asclepius, known as a god of medicine. It is used today as a symbol for the medical profession.

Why do they get confused in the U.S.?
In 1902 the US Army Medical Corp chose the Caduceus as their insignia. Most scholars regard this as a huge mistake. The US Army writes that the Caduceus represents “the non-combatant status of military medicine on the battlefield”. The Encyclopedia Britannica notes, “Among the ancient Greeks and Romans [the Caduceus] became the badge of heralds and ambassadors, signifying their inviolability.” So maybe the US Army was thinking the symbol would convey a sense of “… Hey, hey, hey, don’t kill me, I’m just a messenger delivering the wounded to the hospital…” or some such. That feels like a stretch to me, but what do I know? More importantly, saying “I’m just a messenger” is, at best, nonsensical on a doctor’s scrubs. At worst, it’s terrifying! A person wearing this badge would be, in theory much more likely to kill you (protector of the dead!), sell your organs (protector of merchants!), feed your body to the dogs (shepherds!), hock your jewelry (gamblers!), and tell your mom he hasn’t seen you in a week (liars and thieves!) than help you. Seriously!

There are many articles where historians and professionals delve into this issue. Almost all of them say the US Medical Corps are using the wrong symbol. Here’s a few to get you started:
