Expectorant, tonic, astringent, pectoral, nervine, sedative, aromatic, bitter and stimulant (to digestive tract). The wild cherry is an excellent tonic for convalescence and is a valuable remedy for all catarrhal affections. Its tonic action is mild, soothing and slightly astringent to the mucous membranes (especially those of the respiratory organs and the alvine canal). It has a volatile oil (similar to cascarilla, Virginia snake root, etc.) which acts as a local stimulant in the alimentary canal which increases the appetite and aids in digestion. When prepared in cold water, it yields hydrocyanic acid to the solution, which acts as nervine sedative, quieting nervousness, irritability and relieving heart excitement.
