What Emergency Symbol Should Be on a Medical Alert Bracelet?
In an emergency situation, medical professionals are trained to quickly look for key symbols that indicate a person may have important health information or medical conditions.
When it comes to medical alert jewellery, there are two commonly recognised symbols you may see. But what are they — and does it matter which one you choose?
The Two Common Medical Symbols
The two symbols most often associated with emergency medical identification are:
-
- The Caduceus
- The Staff of Asclepius (often associated with the “Star of Life” symbol used in emergency services)
At first glance, they can look quite similar. Both feature a staff, and both are linked to healing and medicine. A key difference is that the Caduceus features two snakes and wings, while the Staff of Asclepius features one snake and no wings.
Why Is a Snake Used in Medical Symbols?
The snake has long been associated with healing and medicine in ancient cultures.
One explanation dates back thousands of years, including references in ancient texts where serpents were linked with healing rituals. Snakes were also seen as symbols of renewal due to their ability to shed their skin, representing transformation, rebirth, and recovery.
This symbolism carried through into Greek mythology and continues to influence modern medical imagery today.
The Caduceus Symbol
The word Caduceus comes from the Greek kērux, meaning “herald”.
It typically features two snakes wrapped around a staff with wings at the top.
In Greek mythology, the Caduceus is associated with Hermes, the messenger god. It became linked with communication, trade, and negotiation rather than medicine itself, although it has been widely adopted in some medical contexts over time.

The Staff of Asclepius
The Staff of Asclepius features a single snake wrapped around a staff and has no wings.
It is associated with Asclepius, the Greek god of healing and medicine, making it historically the more directly medical symbol of the two.
Today, this symbol is widely used in healthcare and emergency medicine, and is the basis for many modern medical logos, including emergency response organisations.

Which Symbol Should You Choose?
For medical alert bracelets and ID jewellery, the important question is often: does it matter which symbol you use?
In practice, both symbols are widely recognised by medical professionals and emergency responders. While the Staff of Asclepius is more closely linked to medicine historically, either symbol is generally understood in an emergency context.
In most cases, your choice may come down to:
-
- The design available on your jewellery
- Personal preference
- Space and engraving limitations
Some medical jewellery designs only allow for one symbol due to size constraints, and many organisations choose a specific symbol as part of their branding.
The Most Important Thing
While there is interesting history and meaning behind each symbol, the most important factor is simply this:
Your medical jewellery should clearly indicate that important medical information is available.
Whether it features a Caduceus or the Staff of Asclepius, what matters most is that it is visible, recognisable, and prompts a first responder to check for further details.
Final Thought
Both symbols have become part of modern medical identification, even if their origins differ.
So rather than worrying too much about which one is “correct”, the key is to ensure you are wearing medical alert jewellery that clearly communicates your needs in an emergency.

I have been an epileptic for 63 yrs. I wear the Star of Life necklace 24/7/365.
I want to get the Star of Life tattooed on my forearm because I can’t talk after I have a seizure for a good 20 min. but the people there helping me don’t know that. I really appreciate everything they do!!🎗️❤️
