Origin & History
Bilberry Leaf is derived from Vaccinium myrtillus, a shrub native to the boreal and temperate regions of Europe and parts of Asia. It thrives in forest understories and mountainous terrains, where it has been a staple in traditional medicine. The leaves are valued for their distinct phytochemical profile, offering unique benefits for metabolic and circulatory health.
“In traditional European and Nordic medicine, bilberry leaves were prized as a metabolic, circulatory, and detoxifying botanical. They were historically used in decoctions and infusions to support digestive disorders, eye strain, and circulatory imbalances, reflecting a long-standing tradition of whole-plant utilization.”Traditional Medicine
