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

paragraph 9

Because of the extent of the disease, let the medicine be compounded; for when the disease is great and dangerous it is necessary to compound two simples or more, so that when they are compounded the disease is destroyed by them. Because of the varying quality of the disease, let the medicine be compounded, for when the disease has contrary forces it is proper to compound the medicine of contrary things. For example, as is evident in the case of phlegmon4 for which is suitable a compound medicine such as a dispersive, and a cooling medicine.
