Yellow urine after drinking Chinese medicine is caused by the following three factors: first, the Chinese medicine itself is yellow, so the urine metabolized is also yellow, which is the normal color of urine metabolism. Because the color of urine is corresponding to the color of some drugs you drink or some food you eat. For example, the urine metabolized from the red pitaya fruit is also red. Second, after drinking traditional Chinese medicine, the urine is very yellow, which may also be caused by the burning phenomenon, which will change the composition of the urine and cause the color of the urine to turn yellow. Third, there may be urinary system infection, which is caused by the invasion of a large number of bacteria that change the composition of urine. Therefore, it is recommended that patients drink more warm water two hours after taking the medicine, then promote metabolism, dilute urine, and the color will slowly return to normal. At the same time, routine examination of the urinary system should also be done. If there is a urinary system infection, active anti infection treatment should be taken, for example, levofloxacin hydrochloride.
