Quinine, an alkaloid found within the bark of the Cinchona Tree, also known as the Fever Tree, not only provided a revolutionary cure for malaria, redefining Western medicine, but subsequently supported European colonial and ideological expansion throughout the tropics. We decided to retrace the history of its harvest, exploitation and commercialisation, firstly by visiting the Economic Botany collection from the National Herbarium of the Netherlands. Originally from Peru, Cinchona seeds were smuggled out of South America, leading to one of the most profitable enterprises for The Netherlands, which monopolised its commerce during the early 20th century, setting up large scale plantations in Java. The NHN holds some fascinating examples of kina's material history, now forgotten with the advent of synthetic variants for malaria medicines. Quinine also termed the so-called 'quinologist', a professional envolved in the manipulation of the alkaloid, which operated at the cross-overs between chemistry and botany. The manipulation of botanicals for economic purposes was once at the forefront of European medicinal enterprises. Today, we find remnants of its glorified past, with botanical experts almost as threatened species themselves, within this non-descript space which houses the collections from the Leiden, Wageningen and Utrecht herbariums.
