Cinchona bark (bark from plants of the genus Cinchona with antimalarial activity) and its alkaloid quinine were widely used to treat intermittent fevers. This paper aims to quantitatively analyze the presence of Cinchona bark, quinine and other Cinchona bark-derived substances in the Portuguese official pharmacopoeias published between 1794 and 2001. The analysis showed that the Pharmacopêa Portugueza (1876) is the Portuguese official pharmacopeia with the highest percentage of medicines containing Cinchona bark (2.61%). The Farmacopeia Portuguesa IV (1935) is the official pharmacopeia with the highest percentage of quinine-containing medicines (2.34%). Medicines made from Cinchona bark are present in the Portuguese official pharmacopoeias until the Farmacopeia Portuguesa IV (1946). Medicines made from quinine have been present in Portuguese official pharmacopoeias since the Codigo Pharmaceutico Lusitano (1835).
