Action and Therapy.—Spearmint is used much like peppermint. though it is somewhat inferior as a carminative. It is especially valuable to allay nausea, particularly that following a sick headache. The warm infusion is a very agreeable and simple medicine for an acute cold. Spearmint is one of the surest and kindliest diuretics if given in cold infusion; or the essence may be used well diluted with cold water. We frequently employ it to render acetate of potash more effective as well as pleasanter to take. The spearmint increases the watery flow; the potash salt the solids of the urine. Spearmint may be used in strangury, suppression of urine, and scalding of urine, with difficult micturition.
