Pure artemisinin, or Qinghaosu, is the active constituent of the herb Artemisia annua (sweet wormwood). Good quality Artemisia annua contains 0.3-0.5% artemisinin, so pure artemisinin provides hundreds of times more of the active constituent artemisinin than the whole herb itself. Research has shown artemisinin to be particularly beneficial in balancing the microbiology of the GI tract.* Our Artemisinin has had independent cell tests verifying its effectiveness, and we do independent potency assays on every batch, using HPLC. Numerous practitioners have chosen ARG artemisinin as part of the nutritional supplement program they utilize in their practice. Super Artemisinin combines artemisinin and oil derived from the same plant, totaling 200 mg of material per capsule. PhytoArtemisinin provides artemisinin with gleditsia extract, a phytosaponin.
