167. Lauriola: i.e. a tree; hot and dry in the fourth degree; it purges violently; the fruit of the same tree is called cocognidium, and this is hot and dry likewise; the branches, foliage, and seed of this tree are usable for medical purposes; it purges, principally, the phlegmatic humour, and the viscous humours from the extremities of the body, such as the joints, the feet, and the head, and the likes. It purges the melancholic humour in the second place, and, for that reason, it is appropriate for people with sciatica,apoplexy, epilepsy, paralysis, arthritis, podagra, gout of the hand, and any phlegmatic illness; it purges the unnatural choleric humour, that is the lemon-coloured and the yolk-coloured choleric humours; laureola should be put in compound medicines such as oximel and the likes; it should not be given on its own, because it can cause excoriation of the intestines; it should be mixed with gum arabic and bolus armenicus; it should only be given to people who have stout intestines and have difficulty in going to stool; it is of the juice of the foliage of this tree that oleum laurinum is made.
