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

paragraph 5

A composite medicine indeed, as Avicenna says is one compounded from simples or from other composite medicines. For that reason many composites are made from simples and from composites, as is evident from theriac1 which is made from simples and from composite medicines for the three things which enter into it are composite medicines. For that reason the composite has character from the simples and character from the entire form.2
