Mentha Viridis. (Spearmint.)
Preparation.—Prepare a tincture from the fresh herb, ℥viij. to Alcohol 76° Oj. Pose from gtts. v. to ʒj.
Mentha Viridis is not only a stimulant, but is one of the most kindly of the aromatics, and is rarely rejected by the stomach. As a stimulant, it will furnish a cheap and pleasant vehicle for many medicines.
But it is more than this. I regard it as one of the most certain of the vegetable diuretics, and employ it frequently for this purpose. In suppression of urine in children, a teaspoonful of the tincture is added to two ounces of water, sweetened, and given freely. So certain is its action in childhood, that I rarely think of giving anything else, except in cases where there is great irritation of the nervous system, and then Gelseminum is added to it in the usual doses.
