Crataegus monogyna Identity & Plant Part
The botanical entity is Crataegus monogyna Jacq., the common or single-seeded hawthorn, a thorny Rosaceae shrub or small tree of Europe with white spring blossom and dark red autumn fruit. The part used is the fruit, called the haw. Leaves, flowers and the thorny wood are not part of this ingredient.
European pharmacopoeia material for hawthorn is based on the leaf and flower rather than the fruit, so a specification that says only hawthorn extract can mean either. Crataegus pinnatifida, the Chinese hawthorn, is a larger-fruited species. The haw carries procyanidins, flavonoids, organic acids and triterpenic acids, named only as families.
Crataegus monogyna haws are gathered in autumn when fully ripe, and the dried fruit is the starting material for the extract.
