Aristochin.—CO (C_{20}H_{25}N_{2}O_{2})_{2}=C_{41}H_{46}N_{4}O_{5}, the
neutral carbonic ester of quinine.
Actions and Uses.—The same as those of quinine, but, since it is only
slowly acted on by acids, it is said not to produce disturbance of the
stomach and to be notably free from tendency to production of
cinchonism. Dosage.—The same as that of quinine, in powder, mixed with
milk sugar, dry on the tongue or suspended in liquids. Manufactured by
Farbenfabriken, vorm. Friedr. Bayer & Co., Elberfeld, Germany
(Continental Color & Chemical Co., New York).
