Yerba Santa, Eriodictyon. A tonic expectorant quite agreeable to the taste. Of value in chronic, subacute inflammations of bronchial mucous membranes, especially when the cough is dry. Dispensing physicians will do well to stock with the aromatic fluid yerba santa (four times strength of syrup), and use in doses of 15 to 30 I. One teaspoonful of the syrup masks the bitterness of 5 gr. quinine sulphate.
