Why does drinking traditional Chinese medicine cause yellow urine?
Yellow urine after taking traditional Chinese medicine (TCM) may be caused by drug pigment metabolism, insufficient water intake, urinary tract infections, hepatobiliary diseases, hemolytic disorders, or drug-induced liver injury. It is recommended to seek timely medical consultation to identify the underlying cause and receive targeted treatment. Specific explanations are as follows:

1. Drug Pigment Metabolism: Some TCMs contain natural pigments. These pigments may be excreted through urine after metabolism in the body, causing yellow urine. This is a normal physiological phenomenon. It is recommended to increase water intake to promote pigment metabolism and reduce urine discoloration.
2. Insufficient Water Intake: During TCM treatment, insufficient water intake may lead to concentrated urine, which can also cause yellow urine. Increasing water consumption and maintaining adequate hydration can help dilute urine and improve its color.
3. Urinary Tract Syndrome (Lin Zheng): Lin Zheng refers to a condition characterized by frequent and urgent urination, incomplete voiding, and related symptoms due to dysfunction of the kidneys and bladder. Patients with Lin Zheng may experience symptoms such as painful or difficult urination, increased frequency of urination, and yellow urine, possibly accompanied by pain or urgency. Treatment may include oral medications such as Sanjin tablets, Relianqing granules, or Compound Shiwei granules, as directed by a physician. Additionally, maintaining personal and sexual hygiene is important to prevent recurrence.
4. Cholecystitis: When the gallbladder is infected by bacteria, inflammatory exudates may develop, potentially causing abnormal bile secretion and affecting bilirubin levels in the urine, resulting in yellow urine. Associated symptoms may include pain in the liver area, jaundice, and indigestion. Medications such as atropine sulfate tablets, racemic anisodamine tablets, or phloroglucinol injection may be used under medical guidance to manage the condition.
5. Urinary Tract Infection: Poor hygiene habits may lead to urinary tract infections, increasing bacterial presence in the urine and triggering an inflammatory response that affects urine color and consistency, causing it to turn yellow. Accompanying symptoms may include frequent urination, urgency, and pain during urination. Local disinfection and cleansing may be performed using diluted potassium permanganate solution, sodium bicarbonate solution, Compound Phellodendron liquid, or Compound Sophora root lotion, as directed by a physician.
In daily life, when taking TCM, it is important to follow medical advice regarding drug ingredients and dosages, while maintaining healthy lifestyle habits, including balanced nutrition, moderate exercise, and a positive mindset, to reduce the risk of illness.
