Frangeris

Frangeris is a genus of flowering plants in the family Asteraceae, native to the Mediterranean region and the Middle East. The genus includes about 15 species of annual or perennial herbs, with a few being subshrubs. The most well-known species is Frangula alnus, commonly known as European Alder Buckthorn or Common Buckthorn.

The plants in the Frangula genus are characterized by their alternate, simple leaves with serrated or lobed margins. The flowers are small, yellow, and arranged in composite inflorescences. The fruit is a dry, single-seeded achene, often with a pappus of bristles.

Frangula alnus is particularly notable for its use in traditional medicine. The plant contains compounds such as rutin and quercetin, which have antioxidant and anti-inflammatory properties. It has been used to treat various ailments, including digestive issues, skin conditions, and respiratory problems. However, its use should be approached with caution, as it can interact with certain medications.

Another species, Frangula purshiana, is known for its edible fruits, which are used in jams, jellies, and wines. The fruits are small, round, and have a tart flavor.

The genus Frangula is of interest to botanists and horticulturists due to its ornamental value and potential medicinal uses. However, many species are considered invasive in some regions, where they can outcompete native flora.
