Heat accumulated in the bladder damages blood collaterals. Bleeding occurs and the blood is discharged with the urine, so there is blood in the urine. Urination accompanied with pain is called blood strangury, or bloody urine. The heat caused by the stasis that has accumulated in the lower jiao affects the qi transformation of bladder, so there is frequent painful urination that is hot with an unsmooth stream that contains blood. The red tongue and rapid pulse are signs of heat accumulation. The treatment method is to cool blood, stanch bleeding, promote urination, and relieve strangury.
