Rosemary Charm for Toothache
“Llosg ei bren (Rhosmari) hyd oni bo yn lo du, ac yna dyro ef mewn cadach lliain cry, ac ira dy ddanedd ag ef; ac fo ladd y pryfed, ac a’u ceidw rhag pob clefyd.”—Y Brython, p. 339.
“Burn a Rosemary bough until it becomes black, and then place it in a strong linen cloth, and anoint thy teeth with it, and it will kill the worm, and preserve thee from every kind of fever.”
It was thought at one time that toothache was caused by a worm in the tooth, as intimated above.
