60. Bolus Armenicus: i.e. the earth of the mountains of Armenia; it is cold and dry in the second degree; it has the constraining and binding virtues, so that it stops every flux. If the powder of it, and the powder of plantain be mixed together, and put on wounds, it will cure them; it is good if it be red and easily broken; Avicenna says, if the flux be in the head, it should be given to eat in the mouth, and if it be in the stomach or the intestines, it should be given as a clyster.
