Blessed Thistle is a very bitter-tasting herb with centuries of medicinal use for a wide range of conditions. It's in the famous Essiac tea formula and some other herbal combinations. Nursing mothers are the main users of Blessed Thistle supplements today. Although not a medicine, Blessed Thistle herb is classified as a galactagogue, that is, an agent that can enhance milk production and let-down. But good Blessed Thistle supplements aren't as easy to find as other herbs, some herb houses don't even market a Blessed Thistle supplement. Nature's Way specializes in top-quality herbs, so they're a brand a nursing Mom can trust. Blessed Thistle may work even better when combined with Nature's Way Fenugreek supplement.
