Cinchona lost their plants when a wave took them off their ship. The Dutch sent Justus Hasskarl who brought plants that were then cultivated in Java from 1854. The English explorer Clements Markham went to collect plants that were introduced in Sri Lanka and the Nilgiris of southern India in 1860. The main species introduced were "Cinchona succirubra" or red bark, as its sap turned red on contact with air, and "Cinchona calisaya". The alkaloids quinine and cinchonine were extracted by Pelletier and Caventou in 1820. Later two more key alkaloids, quinidine and cinchonidine were identified and it became a routine

The tree can even grow back if roots that are left in the ground are larger than 2 cm in diameter. It reproduces rapidly and spreads its seeds via wind. It reaches maturity and begins seeding in 4 years. Growing at a rate of 1–2 m per year, it quickly reaches a tall height where it can shade out the rest of the native plants. Adult trees grow much slower than juveniles. It has become an invasive species
