Hawthorn
Hawthorn ingredients come from Crataegus monogyna and Crataegus laevigata, thorny shrubs in the rose family grown and wild-collected across Europe, with other species used in China. Two parts are traded: the berries (dried whole, powdered or extracted) and the flowering tops (leaf with flower), usually extracted with water-alcohol. Leaf-and-flower extracts are standardized to flavonoids or oligomeric procyanidins, so the plant part belongs on the spec.
Suppliers sell different products under the same name. Specify the one you need.
Whole or cut dried fruit for teas and syrups, or milled to powder.
Water or hydroalcoholic extract of the fruit, often standardized to procyanidins.
Extract of the flowering tops standardized to flavonoids (as hyperoside or vitexin) or oligomeric procyanidins by HPLC or UV.
Berries or tops from certified organic or wild collection, with certificates tied to the lot.
Compare each result with your own specification when the lot arrives.
Store berries, tops and extracts sealed in lined bags or drums, cool, dry and away from light. Extracts are hygroscopic and cake once exposed to air. Suppliers set shelf life or retest dates and repeat the marker assay at retest.
Marker levels depend on species, plant part and harvest stage, so each lot's COA should state them. Record supplier lot, species, plant part and solvent, and rotate first-expiry-first-out.
