A stable form of artemisinin wherein an artelinic acid or artesunic acid is complexed with cyclodextrin analogs, preferably, β-cyclodextrin. The complexed cyclodextrin artemisinin formulation shields the peroxide portion of the artemisinin backbone from hydrolytic decomposition rendering it stable in solution. Artelinic acid and cyclodextrin are placed into contact with one another to yield a 2:1 molecular species. Artesunic acid and cyclodextrin yield a 1:1 molecular species. The complexed cyclodextrin artemisinin formulation is effective for the treatment of malaria and is stable in solution for long periods of time.
