hawthorn
Hawthorn (Crataegus species) is a medicinal plant containing flavonoids, oligomeric proanthocyanidins, and other bioactive compounds primarily used for cardiovascular support. It works by improving heart function, increasing blood flow, and providing antioxidant effects, with primary applications in treating chronic heart failure and hypertension. The extract is derived from the leaves, flowers, and fruits of the hawthorn plant.
