Traditional logic
The bitter bark was originally used by the Quechua as a muscle relaxant for shivering, and was found to also reduce the fever itself (shivering being a malaria symptom)
Background & history
Quinine, isolated from this bark in 1820 by French chemists Pelletier and Caventou, became one of the most important drugs in medical history. The tree is named for a Spanish countess who, per a popular but historically disputed legend, was cured of fever with the bark in 1630 — though the Quechua, Cañari, and Chimú peoples already knew of its properties long before European contact.

This is a historical and cultural reference, not medical advice. Many of these remedies have never been scientifically validated, and folk reasoning (humoral theory, “hot/cold” classifications, spiritual causation) reflects older explanatory traditions rather than modern medicine.
