The young roots of the common elder possess diuretic properties. A decoction made of the roots and drank freely, will be found beneficial in dropsical affections; it may be associated with juniper berries, horseradish, cream of tartar, etc., with much advantage. The inner bark of the elder forms an efficient hydragogue cathartic and diuretic; it may be employed tinctured in wine or cider. It is taken to the extent of keeping the bowels loose.
