An Irish Version of Gualterus de Dosibus (Author: Walter de Agilon/Galterius Agilinus)

paragraph 83

Yera logodion memphitum is so called since ιερα and sacer mean the same, i.e. blessed; since λογος and sermo mean the same, i.e. speech; and since memphitum and impedimentum mean the same, i.e. impediment; for it cures impediment of the speech whatsoever its source or origin might be. It purges specifically melancholia of the head, and is suitable for epilepsy, vertigo, hemicrania, cephalalgia, and for tremor such as is evident in those who are supposed to have a demon.
