Hedera helix in history

Hedera helix is a climbing evergreen plant that is native to most of Europe and northern and central Asia. It’s a familiar garden plant to many people, and bears an association with the festivities of Christmas since Roman times. It was also a symbol of fidelity in Ancient Greece, presented to newlyweds. 

Historically it was used for a wide array of applications including digestive issues and general wounds. Nowadays it is a widely used natural remedy with well-established medicinal use for chesty cough symptoms.11
