Therapy—It is an antispasmodic, expectorant, and sedative as applied to
such coughs. It will also relieve coughs of sympathetic origin, and socalled
nervous coughs. It will cure the cough of measles more quickly

It will terminate a whooping-cough and leave the patient free from cough,

less frequently.
It is serviceable in all chronic coughs of a dry, irritating character,
especially if the central nervous system be irritated. It is of service in
