Luteolin, found in chrysanthemum flower extract, can potentially reduce serum uric acid levels, suggesting it may help prevent gout.
The research involved two double-blind placebo-controlled studies examining the impacts of chrysanthemum flower extract enriched with luteolin on serum uric acid levels. In a single-dose study, fasting participants consumed a capsule loaded with the luteolin-rich extract before partaking in a high purine meal, with uric acid levels evaluated over time. The second study involved repeated consumption of the capsule over a 4-week period, with fasting serum uric acid measured before and after consumption.
The research found that although luteolin did not significantly affect uric acid levels immediately after consumption, there was an observed decrease in these levels following four weeks of continued ingestion. Most notably, subjects with a baseline uric acid level between 5.5 to 7.0 mg/dL saw a significant reduction after they consumed chrysanthemum flower extract. The trial also established that no adverse effects resulted from the ingestion of the extract.
