Note particularly that there are four species of the liquid medicine, for there is one species called cholalogue which purges choler, another called melanagogue which purges melancholia, another called phlegmagogue which purges phlegm,
A cholalogue is made thus: take violet blossoms, and borage blossoms, of each four ounces; prunes fifty; myrobalani citrini two and one half ounces; cassia fistola when cleaned, tamarinds, rhubarb, and manna, of each item two drams. Let the rhubarb and the myrobalan be strained.
An emmenagogue is made of the same items, with the exception of not containing the myrobalan and rhubarb; for Avicenna says the medicines which purge choler, purge sanguine humor also.
