Felter's Materia Medica on Rubus

RUBUSRUPA8
   The bark of the root of Rubus villosus, Aiton; Rubus canadensis, Linné; and Rubus trivialis, Michaux (Nat. Ord. Rosaceae). Wild and cultivated in the United States. Dose, 5 to 60 grains. Common Names: (1) Blackberry; (2) Low Blackberry; (3) Low-bush-Blackberry. Principal Constituents.—Tannin. Fruits contain citric and malic acids; the glucoside villosin (in Rubus villosus) a body similar to saponin, and about 20 per cent of tannin. Preparations.—1. Specific Medicine Rubus. Dose, 5 to 60 drops. 2. Syrupus Rubi, Syrup of Black Raspberry. Dose, 1 to 2 fluidounces. Specific Indication.—Gastro-intestinal atony, with copious watery and pale feces. Action and Therapy.—The decoction of rubus is a mild and agreeable astringent in watery diarrheas, especially in children, when the stools are clay-colored or pale. There is marked enfeeblement of the stomach and bowels, and the child is fretful, has no appetite, and there is marked pallor of the skin. The syrup or a spiced cordial of the bark and another of the fruit have been used largely in domestic practice to control intractable diarrheas. They act best after a thorough purging with castor oil or similar cathartic has been resorted to. Rubus strigosus (Red Raspberry) has similar uses.1

RUBUS IDAEUS
   The fruit of Rubus Idaeus, Linné (Nat. Ord. Rosaceae). Cultivated. Common Name: Raspberry. Principal Constituents.—Malic and citric acids, laevulose, 4.6 per cent and dextrose (2.5). Preparation.—Syrupus Rubi Idaei, Syrup of Raspberry (chiefly a vehicle). Action and Therapy.—An infusion of the leaves is useful in the diarrhea of relaxation, with copious watery discharges. The fruit as prepared in a syrup—Syrupus Rubi Idaei—is highly prized as a flavored vehicle for medicines and for the beautiful color it imparts to pharmaceutical mixtures. Diluted and iced it forms an agreeable acidulous drink for fever patients. A refreshing fever drink is also prepared by mixing equal parts of syrup of raspberry and vinegar and diluting with water to taste.1
