Quillaia Bark is obtained from an evergreen tree of the natural order Rosaceae - rose order, growing in Chili and Peru, the inner bark being employed.
Quillaia bark, when bruised and macerated in water, imparts to that liquid the property of frothing like soap solution when agitated, which is owing to the saponaria in the bark, the same principle which imparts a similar property to soapwort - saponaria officinalis. Quillaia contains no tannic acid or other bitter principle, and is an article of commerce, being imported in large quantities for cleansing grease from cloth, as it does not change the color of silken or woolen goods; it is also used for cleansing the hair, which it is supposed to preserve and beautify. When the powder is snuffed up the nostrils, it causes sneezing and a profuse nasal discharge.
Quillaia bark has been employed as a febrifuge, to arrest excessive secretion, as an application to ulcers, as a remedy for colds in the head, when it is used as a sternutatory, in the form of powder.
The tincture is composed of quillaia bark I part; alcohol 5 parts; it is also used in the form of infusion and fluid extract.
Quillaia bark, in the form of powder, tincture and fluid extract, is employed as an ingredient of mouth washes, for its frothy and detergent properties; it is also used as an application to chronic ulcers of the mouth, and to arrest excessive secretion of the mucous membrane of the mouth.
