Around 1730 he discovered the medicinal value of the bark and heartwood of certain trees in the treatment of malignant fevers common in Suriname. According to tradition, a traveling Swede bought the secret of the cures and brought specimens of the plants back to Sweden. Linnaeus examined the plants and named the genus Quassia. Later, the name quassia was applied to the drug as well.
