This article contains a semi-diplomatic edition of a short, hitherto unedited, Early Modern Irish text which can be found in the fifteenth-century manuscript TCD 1343, pp. 113–114. The text in question provides recipes for simple medicines containing the dung of a variety of animals: goats, sheep, dogs, cows, bulls, mice, ducks, swallows, doves, and chickens. It is found roughly seven pages after Tadhg Ó Cuinn's An Irish materia medica, edited by Micheál P. S. Ó Conchubhair, and contains references to the second book of Avicenna's Canon of medicine. The two most pertinent capita from (a Latin version of) Avicenna have been transcribed and translated in an appendix.
