148. Gumi: i.e. gum; when the word ‘gum’ in general is spoken, it is to be understood as referring to gum arabic; gum arabic is hot and wet in the first degree, and there are three sorts of it, i.e. ‘alba’ or white gum, ‘citrina’ or yellow gum, and ‘rufa’ or red gum, the white gum being the best of them; it has the virtue of moving the bowels gently and pleasantly; gum arabic is the same as gum Sarasenica, i.e. the gum of the Saracens. Item, this gum, powder of cinnamon and of mint, and fresh wax, if they be mixed together and put on at the top of the stomach, this will stop any vomiting. If it be given with rose water, it will stop dysentery. If gum arabic, dragon's blood and rose water be given, it will stop menstruation. If the same herb be put in the nostrils or in plasters on the temples, this will stop a flux of blood from the nose.
