Turnera diffusa

Turnera diffusa is a plant species utilized within various traditional medicine systems. It has been historically applied for a wide range of conditions, including enuresis, intestinal complaints, diabetes, dysentery, and as a stimulant or diuretic. Scientific evidence regarding its effects is limited but suggests potential; in vitro studies indicate it may reduce PDE5 expression and inhibit aromatase activity, while animal studies show it may affect sperm viability and metabolic markers like adipocyte differentiation. No caffeine has been detected in the plant via NMR analysis. No major safety issues or notable drug interactions are currently recorded.
