In phthisis also, although there may be some expectoration to bring up, yet a good deal of the irritation is in the lung substance, and the efforts of coughing are far greater and more continuous than are required for the removal of expectoration, and they simply exhaust the patient.
Some cases of phthisis, therefore, do better in warmer and moist climates, and especially those where the larynx has become affected by the disease.
The most important point in this treatment consists in forced feeding, the want of appetite which is so prominent in many cases of phthisis being regarded as an abnormal sensation not to be regarded; and under the forced feeding, combined with open-air life, many marvellous recoveries are recorded.
Soddy has used them in phthisis, and Louisa Chesney speaks favourably of the emanations in chronic and acute laryngitis and in tuberculous laryngeal ulcerations.
In the cough of phthisis minute doses are of service, but in this particular disease morphine is frequently better replaced by codeine or by heroin, which checks irritable coughs without the narcotism following upon the administration of morphine.
