cinchonism

Homemade tonic syrups can cause cinchonism, a health condition related to ingesting too much quinine.

Quinine, a naturally occurring quinoline, and the earliest antimalarial drug, displayed a similar propensity to many of these effects, causing a syndrome known as cinchonism.

The great indication is to secure cinchonism as promptly and completely as possible.

The amount of quinia necessary to produce cinchonism must be estimated for each particular case according to the measure of its severity or to states of the system more or less favorable to its absorption.

The treatment of hemorrhagic malarial fevers may be included under the following indications: First, to secure cinchonism as early as possible; Second, to arrest the extravasation of blood; Third, to sustain the patient's strength, and to preserve the systemic fluids at as near a healthy standard as may be possible.
