Medical Ethics Symbol: Caduceus with "Do No Harm" Principle #3725021 (License: Personal Use)

This image features a classic line-drawn caduceus (a staff entwined by two serpents with wings at the top), overlaid with the text “First” above and “Do No Harm” below. Though historically linked to Hermes and commerce, the caduceus is commonly-but mistakenly-used in modern healthcare as a symbol of medicine, often conflated with the Rod of Asclepius. The phrase “First, do no harm” (primum non nocere) reflects a cornerstone of medical ethics, emphasizing prevention of patient injury.

Used on healthcare websites, medical education materials, ethics training modules, or hospital signage to reinforce professional responsibility and patient-centered care. Matches user intent for understanding medical symbols, ethics, or visual representations of Hippocratic principles.
