Overview
Buchu leaf extract, derived from Agathosma species, has been traditionally used in South African herbal medicine for urinary tract and gastrointestinal conditions. It contains bioactive compounds such as flavonoids, quercetin, and volatile oils (e.g., limonene and diosphenol), which may contribute to its anti-inflammatory, antimicrobial, and antioxidant properties [1]. While there is limited clinical evidence specifically on buchu leaf extract, traditional use and phytochemical profiles suggest potential benefits for mild urinary discomfort and inflammatory conditions [5][1]. However, no high-quality randomized controlled trials support its efficacy for any specific condition, and safety data are sparse. As with many herbal products, the lack of standardized dosing and potential for adulteration or contamination remains a concern [7][8].

Clinical Notes
- No established safe or effective dosage due to insufficient clinical evidence.
- Potential for adulteration in commercial products; quality varies widely.
- Theoretical risk of nephrotoxicity due to phenolic compounds; avoid in kidney disease.
- Possible drug interactions with diuretics or antidiabetic agents due to traditional use for fluid balance and blood sugar regulation.
- Avoid use during pregnancy and lactation due to lack of safety data.
