The delusions of Belladonna can be triggered by fever, by injuries to the head, by suppressed menstruation and by hysteria, and they are almost always accompanied by dilated pupils and a red face.
A typical Belladonna delirium is described here by Kent: lIn the evening he was seized with such violent delirium that it required three men to confine him; his face was livid; his eyes injected and protruding, pupils strongly dilated; carotid arteries pulsating most violently; a full, hard pulse, with loss of power to swallow. Violent delirium; broke into fits of laughter, then gnashed teeth disposed to bite and strike those around.’
The following examples may serve to illustrate the almost unlimited delusions of the Belladonna delirium:
The patient throws his arms about, move his lips as if talking, urinates outside the pot.
He has delusions of fire on distant home; of someone trying to take away the bedclothes; of body sinking down between the thighs; of cockroaches swarming about the room.
He believes that he sees cucumbers on the bed, or dead persons, or black dogs.
He imagines himself dreaming when awake; sees giants, a friend’s head sticking out of a bottle, a transparent and speckled head.
He thinks himself a juggler, thinks that he has a transparent nose. He sees brilliantly coloured, glittering objects.
He thinks that a physician is a policeman that he is riding on an ox.
He misrepresents his sensations.
He sees spectres, ghosts, spirits in fire.
His head and nose seemed to be transparent; trees seem to be people in fantastic costume.
He sees large turtles in room.
Kent summarizes the whole picture beautifully:
