The dried berries can be reconstituted and used for the same purposes. Elder berries are used in herbal syrups, tinctures and teas blends. Like elder flowers, the berries make a soothing, heat-clearing herbal tea. Elder berries are also often made into a cordial or a syrup.
To use as a tea, pour 1 cup boiling water over 1 tsp. of herb, cover and steep 3-5 minutes.
