How did they treat Malaria in 1700's?

In the 1700s, malaria was primarily treated with the use of cinchona bark, which contains quinine, a natural antimalarial compound. This bark was often brewed into a tonic, and its use became more widespread after its discovery by Europeans in South America. Other treatments included bloodletting and herbal remedies, although these were largely ineffective. Preventative measures, such as draining stagnant water and avoiding mosquito-infested areas, were also recommended, although the role of mosquitoes in transmitting malaria was not understood at the time.
