If the powdered root be snuffed up the nostrils, it causes sneezing and violent irritation; if chewed, it increases the flow of saliva.

It is said to act as a stimulant of the genital organs, and of the cerebral functions in particular. Active principles, an acrid, volatile oil, and a soft, acrid resin. It is a useful adjunct to strong purgatives, the violence of which it moderates. The tincture is a good form for internal use.

2875. Therapeutic Uses

Short-sightedness. Dr. Turnbull§; having observed that in short-sighted persons the iris was generally much dilated, when looking at distant objects, considered that this might be remedied by agents which would cause contraction of the iris, thus increasing the length of vision, by permitting the rays of light to enter in a straight line. For this purpose he employed a concentrated tincture of Ginger (one part of Ginger and two of Proof Spirit), which was rubbed over the whole forehead, with a view of acting on the branches of the fifth pair of nerves. "The success of this application," Dr. Turnbull observes, " was remarkable. In many cases it had the effect of doubling the length of vision." In some persons in whom the iris was not much dilated, but very torpid, he applied a tincture of Pepper of the same strength as the tincture of

Ginger. This was used until the iris had attained a greater power of contraction and dilatation, after which the tincture of Ginger was again applied. "This treatment," he adds, "has, been attended with the most signal success; and persons who were extremely short-sighted, have very soon become enabled to lay aside permanently their concave glasses." He strongly advises the adoption of this treatment.

In Flatulence, Colic, Spasmodic Affections, and in Gout in the Stomach, particularly when these occur in old or debilitated subjects, the tincture (ante), or an aqueous infusion of Ginger, with the addition of a small portion of brandy or wine, may often be administered with evident benefit. A Ginger plaster (ante) placed over the epigastrium, often relieves the pain in a remarkable manner.

Pereira* states that he has often known a Ginger plaster, applied to the forehead, afford much relief. Toothache is sometimes relieved by the same application to the face, and also by chewing a piece at the same time, so as to act on the salivary glands.
