The “Bowl of Hygeia” sign is the most well-known international pharmacy symbol. Hygeia was the daughter and assistant of Aesculapius (also written Asklepios), the God of Medicine and Healing, according to Greek mythology. A bowl containing a therapeutic potion with the serpent of Wisdom (or guardianship) participating in it was Hygeia’s classical symbol. This is the same serpent of Wisdom that appears on the caduceus, Aesculapius’ staff, which is the medical sign.
