In which type of forests does Cinchona which gives the drug quinine grow naturally ?

Cinchona trees, which are the primary source of the anti-malarial drug quinine, grow naturally in tropical rain forests [t1][t3]. These trees are native to the Andean regions of South America, specifically in lower montane rain forests where high rainfall and humidity provide the necessary growth conditions [t2][t5]. In the Indian context, Cinchona is classified as a commercially important species found within Tropical Evergreen Forests, which are restricted to heavy rainfall areas [t1]. These forests are characterized by high temperatures and significant annual precipitation, supporting a dense, multi-layered canopy [t1][t4]. While Cinchona was historically over-harvested in its wild Andean habitat, it was later introduced to plantations in Asia to stabilize quinine supplies [t7][t8]. Other typical species in this biome include ebony, mahogany, and rosewood [t1].
