Effects of Natural Substances on Lowering Uric Acid

Abstract

Uric acid (UA) metabolism, which includes uric acid production controlled by purine metabolism and uric acid excretion controlled by the gastrointestinal tract and kidneys, is the primary way to maintain the concentration of uric acid in the body. Abnormal functionalizing of the metabolism may cause hyperuricemia, gout, kidney injury, and other diseases. Over the last decade, numerous studies have been conducted on the effect of natural products, including active ingredients of medicinal plants, natural compounds, plant and fungal extracts, traditional herbal formulations, microbial products, alkaloids, etc., on the downward regulation of uric acid for treating uric acid related diseases. Based on the potential sources from 2018 to 2022, 16 studies were reviewed and considered relevant to the topic. This paper is a preliminary summary of the effects of active ingredients of plants, the extracts of plants, and traditional herbal formulations on regulating uric acid levels.
