Herbal Supplement. Darjeeling premium grade. Dry Leaf/Menstruum Ratio: 1:5. We prepare our Green Tea Extract from the young leaves of Camellia sinensis plants which are Certified Organically Grown on the Ambootia Tea Plantation in Darjeeling, India without the use of chemical fertilizers, pesticides or herbicides. To assure optimal quality, the leaves are hand-harvested at their peak of potency and are then promptly heat-dried to stabilize and extract their antioxidant catechins and flavonoids. These leaves are then shipped to our laboratory and thoroughly extracted. www.herb-pharm.com.
