Properties of the Onion.—The onion is possessed of a white, acrid, volatile oil, holding sulphur in solution, albumen, a quantity of uncrystallizable sugar, and mucilage, phosphoric acid, both free and combined lime, acetic acid, citrate of lime, and lignine. Of all the species of allium, the onion has the volatile principle in the greatest degree; and hence it is impossible to separate the scales of the root without the eyes being affected. The juice is sensibly acid, and is capable of being, by fermentation converted into vinegar, and mixed with water or dregs of beer yields by distillation an alcoholic liquor. Although used as a common esculent, onions are not suited to all stomachs; some persons cannot eat them either fried or roasted, whilst others prefer them boiled, which is the best way of using them, as by the process they then undergo they are deprived of their essential oil. Many people who cannot eat onions in a pie or stew, when they are put in raw, find them quite digestible if they are first scalded for a quarter of an hour. Anaemic persons, and those of a consumptive tendency, frequently evince a great liking for onions, and they prove a most useful food for such invalids.
