Support healthy respiratory function with Wild Cherry liquid extract from Herb Pharm. We prepare our Wild Cherry Extract from the thin, green bark of Prunus virginiana trees which are Certified Organically Grown. To assure optimal extraction of Wild Cherry's bioactive compounds, the tender, green bark is hand-harvested only in the spring or autumn and is carefully shade-dried. To extract the bark's full cherry aroma & flavor, we use our special fermentation/extraction process.
