It is recommended to take it on time and according to the dosage under the guidance of a doctor and avoid self-medication. Urotoxic Qing granules in the clinic has the effect of pass the internal organs to lower turbidity, blood circulation and blood stasis, strengthen the spleen to dispel dampness, etc., mainly for patients with early and middle renal failure. If the patient’s creatinine is higher than the upper limit of the normal value, you can take urinary toxin Qing granules to adsorb toxins in the intestine, so that the blood creatinine is excreted from the body, with a clinical efficiency of 76.7%, but the specific effective time varies from person to person, it is recommended to take long-term.
