Great Sage @TheEdVerse , the red cross symbol is almost globally recognised for aid or medical care. Is there such a symbol used within the Realms?

1)
Many healing potions in the Realms display a circle device on the vial or the wax seal over the stopper. That unadorned, simple circle means healing, and is the closest thing to a “beneficial medical aid” rune or badge. 2)
Some healers and "physics" (sellers of medicines, ointments, bandages, and splints) display a banner or signboard with that circle surrounded by radiating rays (simple lines running outwards) to denote medicine.
