Almost from time immemorial, a 'Rob' (a vegetable juice thickened by heat) has been made from the juice of Elderberries simmered and thickened with sugar, forming an invaluable cordial for colds and coughs, but only of late years has science proved that Elderberries furnish Viburnic acid, which induces perspiration, and is especially useful in cases of bronchitis and similar troubles.
To make Elderberry Rob, 5 lb. of fresh ripe, crushed berries are simmered with 1 lb. of loaf sugar and the juice evaporated to the thickness of honey. It is cordial, aperient and diuretic. One or two tablespoonsfull mixed with a tumblerfull of hot water, taken at night, promotes perspiration and is demulcent to the chest. The Rob when made can be bottled and stored for the winter. Herbalists sell it ready for use.
'Syrup of Elderberries' is made as follows: Pick the berries when thoroughly ripe from the stalks and stew with a little water in a jar in the oven or pan. After straining, allow 1/2 oz. of whole ginger and 18 cloves to each gallon. Boil the ingredients an hour, strain again and bottle. The syrup is an excellent cure for a cold. To about a wineglassful of Elderberry syrup, add hot water, and if liked, sugar.
