Theses hasce de renum vesicaeque calculo

...a broth in which fennel seed, anise, etc., have been decocted.

They should take neither food nor drink that is cold, nor hotter than is proper; for everything in excess is an enemy to nature.

Let them abstain from salty, sharp, and acidic things; also from foods of a hard and dense substance, and those which nourish the most; likewise from legumes, except for the black broth of chickpeas.

The quantity [of food] ought to be moderate: indigestions and over-satieties are especially to be avoided.

As for remedies, a thick, viscous, and tenacious humor is removed by contrary medicines, namely those that are attenuating, incisive, and preparatory. Such are: honey of roses, acetous syrup, [the syrup] of the two and five roots, simple and compound oxymel, etc.

An abundance of humor is evacuated by bloodletting: from the elbow while the flow to the kidneys is still imminent; from the popliteal [vein] if it has persisted.

If the stomach is filled with undigested humors (unless something prevents it), vomiting should be provoked. Impurity of the intestines is washed away by enemas.

Purgation is undertaken with milder things, such as manna, diacatholicon, and diasenna.

For plethoric persons subject to the stone, strong diuretics should not be administered before the evacuation of the plethora itself.

To the pharmaceutical branch one may refer those things which are able to break the stone and provoke urine, an abundance of which may be seen in the authors; yet among other simples, these are especially in use: the five opening roots, broom seed, lithospermum, and the herbs betony and saxifrage. There are also fruits, metals, stones, animals, and liquids, all of which it was not my intention to treat here.

The usual compound medicines are Lithontribon, the Electuary of Justin, dialacca, dianisum, etc. Magisterial formulas are those which can be prepared on the spot from simples according to the rules of the art.
