Piperaquine, recrudescence and gametocytes

If piperaquine fails why not use Artemisia afra

Several papers indicate that piperaquine compared to other antimalarials leads to a high level of recrudescence and a higher gametocytogenesis. Gametes are even generatd by piperaquine in asymptomatic patients with low asexual parasite densities. Reuling IJ, van de Schans LA, Sauerwein RW, Bousema T.
