In reality the medical simbol is the Rod of Asclepius not the Caduceus.
The confusion starts with the use of Caduceus and Rod of Asclepius. The Caduceus is a symbol of Hermes or Mercury in Greek and Roman mythology. Caduceus symbol is identified with thieves, merchants, and messengers, and Mercury is said to be a patron of thieves and outlaws, not a desirable protector of physicians. The symbol originated when Mercury once attempted to stop a fight between two snakes by throwing his rod at them, whereupon they twined themselves around the rod, and the symbol was born.[2,8,9] The Rod of Asclepius belongs to Aesculapius, who was the revered Greek God of healing. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4439707/
