"Now, once upon a time, a single drop of sunlight fell from the heavens, and from this small drop of sun, grew a magic, golden flower. It had the ability to heal the sick and injured."
The magic flower was a golden plant that possessed healing magic.
The magic flower originated from a drop of sunlight that fell to the earth. It possessed the ability to heal the sick and injured, a power that a woman, Mother Gothel, exploited for centuries.
However, when the queen of Corona fell ill, the flower was taken from Gothel and turned into medicine. Upon drinking the medicine, the queen was restored to health, and though the flower was no more, its powers passed on to her newborn, Rapunzel.
The flower required a musical incantation to invoke its magic, a trait that persisted even after its power was inherited by Rapunzel. The flower's magic is capable of reversing aging, as well as healing injuries ranging from small cuts to stab wounds. The flower was also able to cure the queen of Corona through ingestion.
