[Research progress on anti-hyperuricemia effects and mechanisms of Chinese medicines based on regulation of intestinal flora and metabolites].

Chronical hyperuricemia, a severe metabolic disease characterized by increased serum uric acid, urea nitrogen, and creatinine, has a positive correlation with the risks of gouty arthritis, diabetes, hypertension, and kidney damage. Abnormal purine metabolism and reduced uric acid excretion are the major causes of hyperuricemia, which, thus, points to a potential strategy of preventing from or delaying the progress of hyperuricemia-related diseases and its complications by effectively controlling the serum uric acid level. Increasing evidence has revealed that Chinese medicines alleviate hyperuricemia through regulating intestinal flora, which plays a pivotal role in regulating metabolites, including uric acid level. The disease treatment with traditional Chinese medicine is based on syndrome differentiation, and Chinese medicines often have multiple effects and a wide range of targets. In this review, we summarized the anti-hyperuricemia effects and mechanisms of active compounds in Chinese medicines, single Chinese medicinal herbs, and Chinese medicinal prescriptions in regulating the uric acid level via intestinal flora and metabolites, which will be helpful for further study and application of Chinese medicines in hyperuricemia treatment.
