Botanical Name: Agathosma betulina Plant Part Extracted: Whole Leaf Contains: Certified organic grain alcohol, distilled water & Buchu extractives. Description: We prepare our Buchu Extract from the leaves of Agathosma betulina shrubs which are Custom Wildcrafted™ especially for us in their natural wild habitat in the Cape Province of South Africa. To assure optimal extraction of Buchu's bioactive compounds, the leaves are hand-harvested at their optimal potency, are carefully shade-dried, and are then promptly air-shipped directly to our laboratory where they are thoroughly extracted. Our Buchu is never fumigated or irradiated.
