All of them are worse in the evening. Symptoms which appear in well defined or very limited areas, such as cough with sore streak down the trachea, or sensation of water running in a narrow line downward from the clavicle, make one think of this medicine and its predilection for single or unassociated manifestations. Under its action the skin becomes dirty white and the face assumes an extremely sickly look. It is one of the best remedies for the ill effects of suppressed eruptions. Motion and rest have an important bearing in the Causticum case.
Many symptoms are better from slow motion and worse during rest.
The stool passes better when standing, and odd but true symptom. In this respect it greatly resembles Aconite and Spongia. The cough and spasmodic symptoms are better from a drink of cold water, but the pains are better from heat. Most of the symptoms are worse in the evening, after eating and from coffee. You should, therefore, not allow patients to drink this beverage while taking Causticum.
