Lungwort, Sticta pulmonaria, a lichen, not the old Pulmonaria officinalis, an odd cultivated herb long abandoned as a remedy. Sticta is one of the drugs that spread from Homeopathic practice into more general use. There is no known active agent in sticta, unless it be a bitter acid similar to that found in Iceland moss. Sticta is said to possess a sedative action upon the vagus and it is more or less used in the treatment of asthmatic cough, hay fever, whooping cough, and laryngeal spasm. The fl. is administered in doses of 1 to 10 minims. While upon a purely empiric basis, many competent physicians assert that sticta gives them good results as an antispasmodic in the treatment of cough.
