Cinchonism
Cinchonism
Cinchonism (/ˈsɪŋkəˌnɪzəm/) is a pathological condition in humans that arises from an overdose of quinine or its natural source, cinchona bark. The condition is named after the Cinchona tree, from which quinine is derived.
Etymology
The term "Cinchonism" is derived from the Cinchona tree, the bark of which is used to produce quinine. The tree itself was named after the Countess of Chinchón, the wife of a viceroy of Peru, who was said to have been cured of a fever by using the bark of the tree.
Symptoms
Cinchonism symptoms can range from mild to severe, and may include tinnitus (ringing in the ears), headache, nausea, dizziness, and disturbed vision. More severe symptoms can include deafness, vomiting, arrhythmias, and visual impairment.
Treatment
Treatment for cinchonism is primarily supportive, with the removal of the offending agent (quinine or cinchona bark) and treatment of any symptoms. In severe cases, hospitalization may be required.
