Linden is an herb that grows on various species of Tilia, or lime tree. Linden Flowers are fringed, yellow-white blooms that grow in clusters with the tree’s heart-shaped leaves. They are known for their rich, sweet fragrance, and are often steeped into tea. Historically, Linden Flowers were used to soothe nerves and treat health problems related to anxiety. Today Linden is used in many cough and cold remedies, as it contains antioxidants and components that soothe and reduce inflammation.
