About

Cinchona pubescens, also known as red cinchona and quina or kina (Spanish: Cascarilla, cinchona; Portuguese: quina-do-amazonas, quineira), is native to Central and South America. It is known as a medicinal plant for its bark's high quinine content- and has similar uses to C. officinalis in the production of quinine, most famously used for treatment of malaria.

Where it grows

C. pubescens has the widest distribution of all Cinchona species, with the native range spanning Costa Rica, Panama, Venezuela, Colombia, Ecuador, Peru, and Bolivia. In Ecuador it is distributed within an altitude from 300–3,900 metres (980–12,800 ft). It also grows well in volcanic soil with high nutrient levels.
