Herbal Supplement. Euphrasia Officinalis. Fresh flowering herb. www.herb-pharm.com. We prepare our Eyebright Extract from fresh (undried) Euphrasia Officinalis plants which are custom wildcrafted in their natural wild habitat. To assure optimal extraction of Eyebright's bioactive compounds, the plants are hand-harvested only while in full flower, and are then promptly extracted while still fresh and succulent. Fresh herb/menstruum ratio: 1:1.2.
