See our full sample process →Evening primrose (Oenothera biennis) is a North American wildflower that opens its yellow blooms at dusk, and Bio-Botanica captures its flower as a hydro-ethanolic fluid extract. Supplied full-spectrum and non-standardized, it gives supplement and beverage formulators a botanical liquid distinct from the more familiar seed oil, ready to dose into water-based systems where an oil would be difficult to carry.
As brands look beyond softgels toward liquid and beverage-friendly formats, a flower-based fluid extract offers a way to feature the recognizable evening-primrose name in tinctures and dosing liquids, extending an established ingredient into formats a softgel simply cannot reach.
The fluid extract blends into hydro-alcoholic tinctures, liquid supplements, and wellness shots, and dilutes into syrups or flavored bases for palatable everyday products. Evening primrose is traditionally associated with women's-health support — structure/function positioning only, not a consumer health claim — a recognizable anchor for a women's-wellness liquid line.
