Aconitum napellus (Acon.)
A state of fear, anxiety; anguish of mind and body. Physical and mental restlessness, fright, is the most characteristic manifestation of Aconite. Acute, sudden, and violent invasion, with fever, call for it. Does not want to be touched. Sudden and great sinking of strength. Complaints and tension caused by exposure to dry, cold weather, draught of cold air, checked perspiration, also complaints from very hot weather, especially gastro-intestinal disturbances, etc. First remedy in inflammations, inflammatory fevers. Serous membranes and muscular tissues affected markedly. Burning in internal parts; tingling, coldness and numbness. Influenza. Tension of arteries; emotional and physical mental tension explain many symptoms. Aconite causes only functional disturbance, no evidence that it can produce tissue change--its action is brief and shows no periodicity.
Better in open air; worse in warm room, in evening and night; worse lying on affected side, from music, from tobacco-smoke, dry, cold winds.
