According to a study published by "Journal of ethnopharmacology", the stem bark of Alstonia boonei has a history of use in the traditional medicine of central Cameroon for malaria treatment and for the prevention of the disease. In studies using a murine malaria model, treatment doses of 200 to 400mg/kg/day were used to correspond approximately to the dosage applied by traditional healers to cure or prevent malaria. When the plant extract was administered separately at a dosage of 400mg/kg, a reduction in parasitemia was obtained. Toxicity studies estimated the LD50 for the herbal combination to be greater than 2779.5mg/kg. These results suggest the plant's potential as an antimalarial prophylactic remedy due to the wide dose interval between the therapeutic dosage and the toxic dosage.
