Pure artemisinin or Qinghaosu, the active constituent of the herb
Artemesia annua (sweet wormwood). Good quality Artemesia 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..... 'more'
