Sues vegetaux, Fr.; Pflanzensafte, G.
Though introduced to professional notice by Squire in the year 1835, and subsequently used by many practitioners, the juices were recognized but once by the U. S. Pharmacopoeia (1870). They consist of the expressed juices of fresh plants, preserved by the addition of one-third of their bulk of alcohol. Considering the great inequality in strength, and, of course, the uncertainty in operation, of fresh juices themselves, varying according to the soil, climate, mode of cultivation, season, and the age of the plant, it may be questioned whether they merit the prominence which has been given them in the past.
