Note particularly as Avicenna says that it is not proper to administer myrobalani in obstructions of the liver and of the spleen because of the styptic properties which they possess since they purge the thinnest portion of the matter and the thickest portion remains. This is converted into calculous concretion, and in this way the obstructions are increased.
Note that the dosage of the myrobalani is varied according as they are put into draughts or into pills. For should they be put into pills it is proper to put as much as two drams; and should they be in draughts it is proper to put one and one half ounces.
