Preparation and History.—This class of preparations is official in the British Pharmacopoeia. Prepared juices were introduced by Squire, in 1830. In 1870, they were made official in the U. S. P., from which they have been dismissed, and, in their stead, the tinctures of recent herbs (Tincturae Herbarum Recentium) substituted. Succi are prepared by expressing the juice from crushed, fresh plants, and adding thereto 25 per cent of alcohol. Owing to differences in strength, due to methods of cultivation, climate, soil, etc., they must necessarily be of doubtful value so far as uniformity of quality is concerned (compare Farr and Wright, Chem. and Drug., 1896, Vol. XLIX, p. 219).
