SPHERE OF ACTION
Through the vegetative nervous system, it acts upon the respiratory mucous membrane, more especially that of the larynx.
Also affects the alimentary mucous membrane, skin and lymphatics.
Great exaltation of the mucous membrane of the larynx and trachea.-DR. DUNHAM. This is its greatest key note.
Violent, incessant, dry, fatiguing cough, with little expectoration; aggravated by pressure, talking, and especially by inspiring cool air, and night.-DR.DUNHAM.
Sense of excoriation behind the sternum.-DUNHAM.
The left chest is more often affected than the right.-D.
Brown, watery, morning diarrhoea.-DR.A.E.SMALL.
This remedy is especially useful in affections of the larynx and trachea. No remedy can be more useful in those affections.
It may well be called a specific for that dry, teasing cough as noted above.
Also acts upon the lymphatics and skin.
