ACONITE. 247
which it is to be applied, and, after its application, protecting the
adjoining parts, such as the lips or cheeks, until the remedy is
absorbed. A drop or two of the tincture, introduced into the
cavity of an aching tooth, will relieve odontalgia ; and the same
quantity will subdue the pain which follows the extraction of a
tooth, especially when the cause has been the inflammation of
the peridental membrane. Tincture of aconite is also serviceable
in the conservative treatment of irritated or inflamed pulps of
teeth. Combined with an equal quantity of chloroform, it is ap-
plied as a local anaesthetic for the extraction of teeth. For the
same purpose it is combined with chloral, pyrethrum, morphia,
etc. (See Dental Formulae.) It is also a useful dressing for the
pulp canals of teeth, preventing the formation of inflammatory
products. The alkaloid, aconitia^ is a useful remedy in neuralgia
of the fifth pair of nerves. (See Dental Formulas.) Care is
necessary in the application of the tincture of aconite to large
surfaces, or where the skin is abraded, as dangerous constitutional
effects may result. Fifteen drops of the tincture, taken inter-
nally, have caused death. The symptoms of poisoning by aco-
nite are as follows : Overpowering sense of fatigue in the lower
extremities, great muscular weakness, dimness of vision, with
dilated pupils ; great dyspnea, the respiration being short and
labored ; the pulse at first slow and small, and afterward imper-
ceptible ; surface of body, tongue and breath cold ; a profuse
perspiration ; muscles of respiration paralyzed ; ceasing of the
heart's action. The antidotes are emetics and stimulants—heat,
brandy and ammonia; patient kept flat on back.
