Overview of Hawthorn berry
What is Hawthorn berry?
Hawthorn berries are small, tart fruits that grow on trees and shrubs belonging to the genus Crataegus. This genus includes hundreds of species found throughout temperate regions of the Northern Hemisphere, including parts of North America, Europe, and Asia. The berries, which are typically red but can also be black or yellow, are a type of pome fruit, similar in structure to miniature apples.
Botanical Profile and Composition
As members of the Rosaceae (rose) family, hawthorn plants are characterized by their thorny branches and white or pink flowers. While the leaves and flowers are often used in herbal preparations, the berries are particularly noted for their specific profile of bioactive compounds.
The primary constituents found within the fruit include:
- Flavonoids: Such as hyperoside, vitexin, and quercetin.
- Oligomeric Procyanidins (OPCs): These are condensed tannins that contribute to the plant's phytochemical activity.
- Organic Acids: Including citric and tartaric acids, which provide the fruit's characteristic tartness.
- Triterpenoids: Naturally occurring compounds found in the skin and pulp.
Historical and Traditional Use
Hawthorn has a long history of use in various traditional practices. In traditional Chinese medicine, the dried fruit (known as Shan Zha) has been utilized for centuries. Similarly, in European herbal traditions, the berries have been recognized since at least the first century for their distinct properties. Historically, the fruit was consumed as a food source in jellies, wines, and teas before becoming a common subject of botanical study.
