CHAP. LXXXIX. Of Bloody Ʋrine.
BLood may be conveyed from many Parts to the Urinal Passages, and be mixed with the Urine, and so ren∣der it bloody; but that rarely happens, and we only dis∣course here of Diseases of the Reins and Bladder, and of that bloody Urine which proceeds from the fault of those Parts: The Blood flows from the Reins and Bladder, as from all other Parts, either by opening of the Vessells, by a Rupture, or a Solution of the Continuum, but very rarely, by reason of the Thinness of the Veins which carry Blood to these Places.
The most frequent causes, are Fullness and Acrimony of the Blood, and a Stone in the Kidneys, a Fall or Blow, the lifting or carrying of a great Weight, violent Motion of the Body, or the like.
When Blood flows from the Bladder it is little in quantity.
The Cure of this Disease must be varied according to the Variety of the Causes: And first, If it proceed from a great quantity or Acrimony of the Blood, Bleeding must be used frequently, but little must be taken away at a time; and in this case Cupping glasses, Frictions, and Ligatures must be used to the upper Parts, and Derivation must be made by bleeding in the Foot, or by opening the Hemorrhoidal Veins.
When serous and Cholerick Humours promote this Evacuation, they must be purged off by Catharticks used by Intervals.
Take of Rubarb a little torrified and powdered one dram, of Coral prepared half a Scruple, of the Whey of Goats-milk, or of Plantane-water, three ounces; make a Potion.
