Buchu Betulina Leaf

Buchu leaves contain diosphenol and volatile oils such as limonene and pulegone. These compounds are excreted largely unchanged by the kidneys, producing an antiseptic and diuretic effect directly on the urinary tract mucosa. This mechanism helps reduce inflammation and combats bacteria, validating its traditional use for bladder infections (Evidence Level: C).

Buchu may interact with diuretic medications like furosemide, potentially increasing the risk of dehydration or electrolyte imbalances due to its own diuretic properties. Additionally, because Buchu contains pulegone, there is a theoretical risk of increased liver toxicity if combined with hepatotoxic drugs. Consult a healthcare provider before combining with prescription medications (Evidence Level: C).

The standard adult dosage for Agathosma betulina is 1 to 2 grams of dried leaves taken three times daily. This can be administered as an infusion (tea) or in capsule form. Due to the potential for kidney irritation with overuse, treatment duration should be limited and dosages should not be exceeded without professional guidance (Evidence Level: Traditional).

No, Buchu is considered unsafe during pregnancy. The herb contains pulegone, a compound known to stimulate uterine contractions and potentially cause miscarriage. Additionally, the volatile oils may be toxic to the developing fetus. Breastfeeding women should also avoid Buchu as safety data is insufficient (Evidence Level: D).

While generally safe at recommended doses for healthy individuals, overuse of Buchu can cause kidney irritation. People with pre-existing kidney disease should use this herb with extreme caution or avoid it entirely. Common side effects include gastrointestinal upset, but the primary safety concern regarding the kidneys arises from excessive or prolonged dosing (Evidence Level: C).
