Arnica
himself, lies down and goes off in to a sleep of terror, jumps up again with the fear of sudden death and says: "Send for the doctor at once". The fear of death is very much exaggerated if he is alone.
From such an experience his whole organism is affected, there is a horror that overtakes the patient and there are congestions that affect mostly the upper part of the spine.
He becomes forgetful, absent minded, cannot concentrate, loses all interest in his work, reads something and forgets immediately what he has just read, does not remember if he has just turned off the gas and goes back to check it etc.. Oversensitive, cannot bear pain. Restless because of pain and soreness.
Then we have a mental picture of Arnica which is characteristic during high fever, in serious diseases like typhus, malaria, scarlet fever, when the eruption does not appear, or in brain damage from extravasation of blood due to a concussion, or in subarachnoid haemorrhages, in apoplexy etc.
In such instances there is a profound prostration followed by delirium and finally stupor, unconsciousness and coma. Stupor with involuntary discharges of stool and urine.
During such states the Arnica case may see delusions, imaginations, or hallucinations. He may imagine the following: high walls and buildings falling upon him; that he is about to be arrested; that he visits a churchyard; that he is holding a council; that he is seeing a mutilated corpse, black images and phantoms. He dwells upon seeing these images and phantoms; he sees black forms of spectres, ghosts and spirits when dreaming; has fantastic visions.
Arnica will have constant muttering in brain damage (Lach.) and delirium like delirium tremens. Arnica cases may also have delusions that they are well while in a severe precarious condition, close to death. They may look at the doctor and say "1 do not need you, I am well", refusing to take the medicine.
Eventually the Arnica case may go into a semi-comatose state, from which, though he can be aroused and answers correctly if he is
asked a question, as soon as he finishes the sentence or even before finishing it, he falls back into a stupor. This is a grand characteristic of Arnica and the remedy will definitely be indicated if the pathology is similar to the ones described above. If he becomes unconscious he will
lie there as if he were dead.
