Elder trees (Sambucus niger) are one of my favorite medicinal plants to work with. They help to keep you healthy and they taste great too. Theleaves, flowers, and berries all contain medicinal properties. The bark and roots were commonly used in the past, but their use has become obsolete. The leaves are commonly used externally as a salve for bruises and wounds. The flowers are used as an infusion to treat coughs, colds, and allergies. The flowers are also used as a home remedy for ear aches. If all else fails, elder flowers make an excellent wine.
