There are two different opinions about the origin of snakes and the scepter symbolizing the middle. The first origin is ancient Greek mythology. Snakes and wands are to commemorate the great imperial doctor Asclepius. After Asclepius was resurrected and officially made a god, he usually appeared in front of people in a standing position, wearing a robe and holding a scepter with a snake wrapped around it, and then the scepter became a symbol of medicine. The snake on the scepter is a symbol of medicine and health.
The second origin comes from the Bible: it is said that Moses cast the shape of a snake in bronze and put it on a post. If someone is bitten by a poisonous snake, just look at the bronze snake under the pillar and it will heal immediately. The above two stories are the background of the design of the life star logo.
