Artemisia annua came under the spotlight during the Vietnam War. Viêt-Cong who operated in swamps and rain forests lost more soldiers by mosquito bites than by American bullets. Ho Chi Min turned to China for help. Researchers at the Chinese Institute of Material Medicine had found a region of China that reported no malaria cases, and when they investigated, they discovered that its people drank a decoction of Artemisia annua at the first symptoms of malaria.

Sugar feeding is a fundamental characteristic of mosquito life. It is the basic food of adult mosquitoes, as floral nectar or honeydew. It is the only nutrient consumed by males and probably the more common one for females, even if they need vertebrate blood to produce eggs. Malaria parasites also are dependent on glucose as a nutrient source. As Plasmodium has no capacity to store energy in the form of glycogen they rely entirely on an exogenous supply of glucose. The infected erythrocyte exhibits a substantial increase in its permeability to low molecular weight sugar.

It is generally or it was believed that quinine is prophylactic. But several papers have questionned this believe and a large scale clinical trial from India in 1918 demonstrated that it is not the case and that large quantities of quinine have been swallowed by a large number of people without providing protection against the infection nor significantly reducing transmission
