Aconite is poisonous in all but the smallest doses and is rarely prescribed for internal use.  More commonly , it is applied to unbroken skin to relieve pain from bruises or neurological conditions.  In Ayurvedic medicine, aconite is used to treat neuralgia, asthma, and heart weakness.  Aconite has been added to salves because of its painkilling action on neuralgia, lumbago, and rheumatism.  The tincture has been given in one-drop doses for heart failure, high fevers, pneumonia, pleurisy and tonsillitis.  Use only under a professional’s supervision.
