XXIV.
The blood is faulty in quality when it is either thicker or more viscous: and this due to errors either internal or external.

XXV.
Internal ones are a cold intemperance of the stomach or liver, whence the thicker blood cannot pass through. External ones are a diet that makes one thick and cold, as well as medicines producing the same effect.

XXVI.
Suppression also occurs by a vice of the parts, namely, of the uterus itself and the veins. Now the veins are those which are led to the uterus, and those which are disseminated through its body.

XXVII.
The veins which are led to the uterus can cause suppression while they are narrowed, and especially while they are obstructed. This obstruction happens by matter that is either copious, viscous, or thick.

XXVIII.
Copious, as we proposed above. But the thick and viscous matter is twofold; for either this thick and more viscous blood redounds in the liver and the whole body, or it is only in the veins pertaining to the uterus, while in the rest of the body the blood is thin.

XXIX.
Again, this obstruction is induced by errors either internal or external, about which [we shall speak] in a more convenient place.

XXX.
The veins which are disseminated through the body of the uterus bring about this evil when they are narrowed, or grow together, or are compressed, or subside.

XXXI.
They grow together when an ulcer heals: they are compressed by a tumor
