Is most useful in acute coryza, having the characteristic of excessively profuse secretion, that from the eyes being bland and non-excoriating, while that from the nose is very acrid and excoriating (Reverse, Euphr.). Associated with this condition we usually find the characteristic catarrhal symptoms of the larynx as noted above, and a severe frontal headache. These symptoms have also led to the successful use of the drug in the first stage of measles. It has also been used for neuralgia accompanying the characteristic catarrh, and also when following the injuries of nerves after surgical operations (Hypericum) the pains being fine, thread-like, and shooting in their character.
