Traditional Urinary Support Nettle Leaf has been used for urinary support; its use dates all the way back to ancient Greece. Traditionally, nettle leaves were boiled down into a tea or crushed into tinctures and powders. Nettle is a flowering shrub, though its hair-covered leaves and stem can sting your fingers – hence its Latin name, which translates to “I burn.” We source Nature’s Way Nettle Leaf from Eastern Europe, where it grows best.
