Artemisia annua has strong allelopathic properties as was documented by Mediplant for the high artemisinin hybrid. In other words the plant becomes invasive and inhibits the growth of other plants or cash crop on fields where Artemisia has been planted for the extraction of artemisinin by Bigpharma.
With WHO's blessing Keasling's synthetic artemisinin replaces the natural product: an economical disaster for African families who have invested all their meager resources in Artemisia annua plantations, lured by the promise of big profits.
Not only are they now confronted by poverty, but also by hunger and starvation. Their fields have become sterile.
