History, Description, and Chemical Composition.

This plant is indigenous to Europe, and introduced into this country; it usually attains the height of 6 or 10 feet, and flowers in June and July. The flowers are succeeded by a scarlet fruit called hip. The fruit (Rosae Caninae Fructus) was official in Br. Pharm., 1885. It is inodorous, but possesses a rather pleasant, sweetish, acidulous taste, which is increased by the action of frost. The hip or fruit (not a true fruit) consists of the developed tube of the calyx, inclosing within its cavity numerous carpels or true fruits; these must be carefully removed before it is used for pharmaceutical purposes. After having been dried it contains gum, citric acid, malic acid, a large proportion of uncrystallizable sugar, various salts, and traces of wax, resin, and volatile oil. Its properties are preserved by beating the pulp with sugar (C.). The vanilla-like fragrance of the fruits is due to the presence of vanillin (Schneegans, Jahresb. der Pharm., 1890, p. 148).
