They have lobed or toothed leaves and produce clusters of small, fragrant flowers in spring.The berries are small, round, and typically red or black when ripe, depending on the species.

The berries contain flavonoids and other antioxidants that help protect cells from oxidative stress and inflammation. In traditional Chinese medicine (TCM) and European herbal medicine, hawthorn berries are used to treat cardiovascular conditions such as angina, high blood pressure, and congestive heart failure.
