Coffeinum.
Coffein or Caffein, an alkaloid obtained from Coffea arabica. C8 H10 N4 O2.
Trituration of the alkaloid, and also of the Citrate of Coffein.Characteristics.─
A proving has been made with
this alkaloid, but has brought out no symptoms not included in the pathogenesis of Coffea. Pulsation of the arteries on head and temples was very
marked. Sparks before eyes─roaring in the ears. Vomiting with relief of
all symptoms. The Citrate of coffein, which is used
largely in allopathic practice, has occasioned dangerous poisonous symptoms in a number of
cases. These seem the most characteristic: Restlessness and dizziness; unable to keep erect.
Violent precordial anxiety. Palpitation. Abdominal pulsation. Violent trembling of all the
extremities. Grating of the teeth. Features expressive of the greatest anxiety. Feeling of
constriction of the neck and throat, recurring periodically every fifteen minutes. Pulse
very rapid.® 2000
