Meaning
The caduceus ☤ is the staff of Hermes (Mercury): a rod with two snakes twined around it and, usually, a pair of wings. In classical myth it is a herald’s wand of commerce, negotiation, and messages — not originally a hospital emblem.
Medicine’s older Greek symbol is the Rod of Asclepius: one snake, no wings. In the United States the caduceus was adopted by some military and commercial medical groups, so many clinics now display ☤ even though historians still prefer Asclepius’s single serpent. When you search “caduceus symbol,” you usually want this winged double-snake staff.
Copy ☤ (U+2624) for text. For tattoos, artists distinguish the two staffs carefully if you work in healthcare. Using the caduceus to mean “I’m a healer” is common in the US; using it to mean trade, travel, or clever speech is closer to the Greek original.
Origin
Greek and Roman emblem of Hermes/Mercury; later adopted (especially in the US) as a medical insignia, competing with the Rod of Asclepius.
Cultural variations
Classical use is commerce and the messenger god. US medical branding often treats the caduceus as a doctor’s mark. Pharmacy and some European medical bodies still prefer the single-snake Asclepius rod or a bowl-of-Hygieia.
