There was a bit in a book I read long ago that documented how little old ladies in Mexico would take buds, soak them in tequilla and use it as a rub for arthritic hands. Don't know how well it would work, but you might want to try it! If all else fails, you can still make canna-margaritas with it! Plus you might find some info in these.- Granny:hippy:
