To judge from the comparative evidence, some form of this charm has been current in the Indo-European-speaking world now for hundreds, if not thousands, of years.
Here's the Hwicce/Tribe of Witches version.
Prescription: Three repetitions, three times daily, until sprain heals.
Old Hornie Rade
Old Hornie rade,
his foal's foot slade.
Down he lighted,
his foal's foot righted.
Flesh to flesh,
sinew to sinew,
bone to bone:
heal! in the name
of Old Hornie!
(Repeat three times.)
Rade = rode
Slade = slid
For Alana
(since it fits like a catskin glove):
a quick and thorough healing.
