We prepare our Celandine Extract from fresh (undried) whole Chelidonium majus plants which are Certified Organically Grown on our own farm. To assure optimal extraction of Celandine's bioactive compounds, the plants are hand-harvested while in full flower and are then promptly extracted while still fresh and succulent. Caution: Seek expert medical advice before taking during pregnancy or nursing. Not for persons with biliary obstruction or history of liver disease. Not for use longer than 4 weeks except under expert medical care.
