Patients with high uric acid can drink pu-erh tea, which does not significantly raise uric acid, and drinking more tea can urinate more, which is conducive to the excretion of uric acid. The normal blood uric acid level in human is 180-420μmol/L. If it is higher than 420μmol/L, it is called hyperuricemia. Long-term hyperuricemia may lead to gouty arthritis and also increase the risk of cardiovascular disease, so it is important to keep blood uric acid within the normal range in general. If you do not have gouty arthritis, it is usually fine to keep your blood uric acid below 360 μmol/L. If there is a gouty arthritis attack, it is recommended to control blood uric acid below 300μmol/L. Most patients with gout need to take uric acid-lowering medication in addition to diet control.
