Sticta Pulmonaria, Lung Wort, a lichen found growing upon rocks and trunks of old trees. Possesses a sedative action upon the vagus, lessening irritation and controlling cough with pain in the occipital region and between the scapulae and in the respiratory muscles. It is used in short, hacking coughs, and in influenza with irritating catarrhal discharges. In hay fever it has given me better results than has any other internal remedy. Many cases yield to its influence promptly, and are markedly relieved, while others take pretty full doses. Dose, ec. tr., 1/2 to I0 I., @ 2 to 30 I..
