DO YOU KNOW THE SYMBOL YOU SEE IN WORLD HEALTH ORGANIZATION (WHO) logo and medical insignias is known as the Rod of Asclepius.

Its origin is a fascinating blend of Greek mythology and ancient survival practices.

1. The Mythological Origin

The God: Asclepius was the Greek god of healing and medicine, the son of Apollo.
The Legend: According to myth, Asclepius once watched a snake bring life-saving herbs to another dead snake, reviving it. He used that same knowledge to heal humans, eventually becoming so good at it that he could even bring the dead back to life.

The Symbolism: The snake represents rejuvenation and renewal (because it sheds its skin), while the staff represents authority and the support a physician provides.

2. The Practical "Worm" Theory

Some historians believe the symbol has a very literal, non-magical origin. In ancient times, doctors treated Guinea worm infections-parasites that live under the skin.
To remove the worm, a doctor would make a small cut and slowly wrap the end of the worm around a small stick or staff over several days to pull it out.

Ancient doctors may have advertised their services by putting a sign outside their doors showing a "worm on a stick."

3. The Big Confusion: One Snake vs. Two

There is a massive historical "error" that still exists today:
Rod of Asclepius (1 Snake, No Wings): The true symbol of medicine (used by the WHO, AMA, and the book pages you shared).

Caduceus (2 Snakes, Wings): This is actually the staff of Hermes, the god of commerce, travelers, and... thieves.

The Mistake: In 1902, the U.S. Army Medical Corps mistakenly adopted the Caduceus (the symbol of commerce) as their insignia. Since then, many commercial healthcare companies have used the "wrong" symbol because it is more symmetrical and visually appealing.

Did you know the 'medical' symbol with two snakes is actually a 100-year-old mistake? It’s the symbol for commerce and thieves. The real symbol of healing has only one snake-the Rod of Asclepius.
