The most peculiar disturbance of respiration in Drosera is, however, a sensation of oppression of the chest as if the air were retained in the body while coughing and speaking; it is as though the air could not get out. Talking especially aggravates the oppression, and also makes inspiration very difficult; with every word the throat seems to be contracted. It is remarkable that talking will distinctly relieve the mental anxiety of Drosera, but greatly disturbs the respiration.
Moreover, a severe and painful feeling of constriction accompanies the cough. It may be felt in the chest, in the hypochondria, even in the hypogastrium. The patient is compelled to press his hand against the painful spot, in order to relieve the pain a little. For instance: ‘The region between the short ribs suffers from a contractile pain which checks the cough; he has so much pain that he cannot cough, unless he presses his hand against the pit of the stomach’.
This sensation of constriction is frequently accompanied by nausea and gagging, especially if there is cough without any (or sufficient) expectoration. ‘Wants to vomit during the cough’. ‘Vomits water, mucus and food during the cough’. ‘The cough affected the abdomen if expectoration was not sufficient, like a griping and heaving to vomit’.
Usually the cough is provoked by a peculiar tickling irritation in the throat. If this irritation is coupled with a sensation as if there were a soft body in the throat, like a feather, this is a strong hint for Drosera. But in the provings we also find expressions like a ‘burning rawness’ and a ‘rough and scraping sensation of dryness’ in the throat. ‘Cough from tickling in larynx, with vomiting of food’ is a well-confirmed Drosera indication that has led to cures in many cases.
