Action and Therapy.—Anise is an agreeable stimulating carminative employed principally for the relief of nausea, flatulency, and the flatulent colic of infants. Anise imparts its odor to the milk of nursing mothers. It is an ingredient of Paregoric (Camphorated Tincture of Opium), and is largely used to impart to or correct flavor in medicinal preparations, especially cough mixtures. For infants the infusion is the best preparation and it should not be sweetened. The spirit (½ to 1 fluidrachm) given in hot water is more agreeable and effective for older children and adults. The oil (1 to 5 drops) on sugar may be used by the latter, if desired.
