The administration of the drug being persisted in, the impulse of the heart grows rapidly weaker, until its power is more or less nearly extinguished, and death soon results from failure of respiration. Its action is rapid and evanescent. Characteristic Symptoms. Mind Anxiety, as if something might happen; must have fresh air. Head Headache worse on left side. Heat and throbbing in the head, with feeling of intense fullness in the head. Beating, throbbing, bursting sensation in the head and ears, with constriction of the throat and heart (Belladonna, Hyoscyamus, Stramonium).
