cannot sleep. Little exertion is enough to exhaust him, and he is averse to mental work. Headaches prevent him from any mental exertion, and if he does engage in mental activity, the pain worsens. He becomes disinterested and forgetful.
The proving of Cainca brought out an additional symptom, ‘All his actions are marked by a certain haste’. Hering mentions ‘weeping with cough ’ as a clinically confirmed symptom. There are feelings of anxiety and uneasiness in the abdomen.
Generalities
Cainca has not been used much, but has been given with success in cases of water retention, especially when associated with dry skin. Pollakisuria may be an indication for Cainca, especially while travelling, as hinted at in Hering’s description: ‘While travelling 18 miles in the cars, he had to urinate 18 times.’
The remedy has also cured fatigue due to bumpy travelling, e.g. riding on horseback.
The abdomen is sensitive to touch.
Motion and eating aggravate, while rest ameliorates.
There is a general weakness, especially after evening meal.
In general, Apocynum cannabinum is remarkably analogous to Cainca.
