About this botanical

Evening Primrose (Oenothera biennis) is a plant in the Onagraceae family, native to North America. Bio-Botanica extracts the flower of Evening Primrose and currently offers 2 Evening Primrose extracts to formulators.

Every Evening Primrose extract is produced by the Bio-Chelated cold-extraction process at our cGMP facility in Hauppauge, New York. Low-heat extraction is used to carry the botanical’s naturally occurring constituents through in their native ratios, which is what Bio-Botanica means by a Holistically Balanced, full-spectrum extract. The company has been family-owned and manufacturing botanical extracts since 1972.

Evening Primrose is available as cosmetic glycerin extract and fluid extract. Formulators specify these for dietary supplement, food and beverage, and cosmetic and personal care applications, with the carrier and format chosen to suit the finished product. Traditional uses of the botanical are noted for context only — structure/function positioning, not a consumer health claim. Every lot ships with a specification sheet, certificate of analysis and safety data sheet, and samples are available for evaluation.
