White urine in acute fevers indicates that the matter has deviated away from the blood vessels and urinary organs. Often it is directed to the brain, and then a headache and pain occur, and sometimes it is directed to some of the insides, and this indicates a tumor. If there are favorable signs, then the matter will come out by vomiting, but this happens less often, and more often, especially if there are no signs of vomiting, it comes out when weakened and leaves behind abrasions in the intestines. If the urine during an acute fever is at first white and watery, and then, along with the whiteness, it becomes cloudy and thick, this indicates impending spasms and death.
Know that in acute diseases it would be a mistake to make a decisive judgment about the impending death of the patient due to black urine, although blackness itself is not a good sign. However, if this is accompanied by other bad signs, but you see that the forces are significant and capable of producing all kinds of emptying, then relief comes after them. This happens, for example, in women when bad juices come out during cleansing; Therefore, this phenomenon is safer in women, because in them such matter often comes out through menstruation.
Know that the scantier the black urine, the worse, for this indicates the drying up of moisture; The thicker the urine, the worse it is in acute diseases.
When black urine in acute fevers is thin and somewhat thin and has a suspended sediment in the form of flakes and a pungent odor, this portends headaches and mental confusion. At best, such urine indicates the impending flow of black blood from the nose, for the matter is sharp and takes over, and sometimes due to the heat with such urine there is perspiration, if the heat is not excessive, but not too small and drives the matter towards the muscles; perspiration is then preceded by goose bumps.
When black urine, in which there is a black suspended sediment, round and dense, there is no odor and there is tension in the sides, swelling of the hypochondrium and perspiration, this is a sign of imminent death; tension in the hypochondrium indicates spasms, and perspiration occurs from weakness. Watery urine, cast black, indicates by its liquid the duration of the disease, and by its blackness its malignancy. They say that if a patient emitting such black, thin urine wants to eat, then he will soon die.
If watery, black urine changes and becomes red and thick and has no odor, this indicates liver disease and, in particular, jaundice. The fact is that the transition from liquid to thickness and from black to red indicates a lack of warmth and the presence of digestion of juices, and such phenomena are accompanied or followed by a feeling of relief. If this is not the case, then there is matter stuck in the liver, from which it cannot be cleared, and has caused a blockage, and if the matter is hot, then you seem to see with your own eyes how it forms a tumor.
If the watery black urine, which is emitted in acute fevers little by little over a long period of time, is accompanied by pain in the head and neck, it indicates a gradual disappearance of reason; in women it is safer.
