See our full sample process →A hydro-ethanolic fluid extract, Willow Bark Fluid Extract concentrates the bark of Salix alba, the European white willow found across Europe, western and central Asia, and North Africa, in a food-grade ethanol-and-water base. Bio-Botanica presses it full-spectrum and non-standardized, giving supplement and beverage developers a ready-to-dose liquid rather than an isolated fraction. The concentrated format keeps dosing compact for two-ounce and shot formats.
White willow is a heritage botanical still in steady demand across the supplement aisle, a sector Grand View Research projects will reach USD 393.56 billion by 2033. A concentrated ethanol fluid extract lets brands carry willow bark into tinctures and wellness shots without reformulating around a powder.
The liquid drops straight into hydro-alcoholic tinctures, herbal bitters, and two-ounce liquid supplements, and it can be diluted into syrups or glycerin blends for gentler formats. It combines readily with other traditional botanicals in a compound tincture. With no function areas attached to this listing, positioning stays on the botanical's long heritage and format flexibility rather than any health claim. Willow bark is traditionally associated with joint comfort — structure/function positioning only, not a consumer health claim — a long-documented use in North American and European herbal practice.

The white willow bark is worked at an FDA-inspected cGMP facility in Hauppauge, New York using the proprietary low-heat Bio-Chelated method, and each lot is verified in an onsite laboratory equipped for HPLC, ICP/MS, microbial, and heavy-metal analysis.
