Origin & History
Black Grape Leaf Extract is derived from Vitis vinifera, a vine native to temperate regions across Europe, Asia, and North America, cultivated since antiquity. Revered in Mediterranean and Middle Eastern herbal traditions, its leaves are a concentrated source of beneficial compounds for vascular and circulatory health.
“In Greco-Roman and traditional Persian medicine, grapevine leaves were decocted for wounds, inflammation, and circulatory concerns, with black grape varieties particularly prized for their medicinal potency. The leaves were symbolically viewed as "botanical armor," protecting vitality through inner and outer resilience.”Traditional Medicine
