But amongst diseases in defect the most common is obstru∣ction of passages,
whose common Indication is, apertion of obstruction But sith thence the causes of obstruction may be various, particular indications are taken from them, and those being taken away, the obstructions are also opened: Therefore that obstruction which is made by thick and viscid humours, requires attenuating, cleansing, and cutting medi∣cines; amongst which, sometimes the weaker, sometimes the stronger are used, according to the nature of the humour it self, and the condition of the place wherein it resides: But if obstruction be made by many humours, and they con∣trary to nature in their whole kind, the cure thereof consists altogether in evacuation. But if the humour be not contra∣ry to nature in its whole kind, but onely offends in quantity, the Indication is Apokenosis, i. e. That which abounds is to be abated, according to its abundancy: But although all the obstructing causes should be evacuated, yet they differ as well in other things, as also especially in this, that each of them require their peculiar and convenient places: Those which obstruct the Breast and Lungs, are to be ejected by cough, nor can they easily be evacuated any other way: But those which are contained in the Liver, or in Veines, or in Arteries, or in the Reines, are cast out by Urine, the belly, or vomit.
The other kinds of straightness,
when the causes are ta∣ken away, they are likewise taken away, things growing together, or Coalescents, since it comes to pass by the grow∣ing together of parts and sides of a passage Indicate a Me∣dicine breaking and taking away that Siccatrizing again.
Constipation Indicates the cause to be taken away,
which make that straightness.
Compression since it proceeds from externall causes, rest∣ing upon the passages, the Indication is common, namely, to take away that cause of pressing together, and shutting the passage, but the speciall Indications are various, according to the variety of causes, and the whole cure consists in the abla∣tion of those causes which shall be shewn in their owne place.
Lastly, Subsidence, if it be caused by too much humidity, the part is to be dryed: If the part be wrung hard, and as it were contracted, with drying things, and too many Astrin∣gents, and cold, the contraries, namely, Relaxing and moist∣ning things are to be exhibited.
