As regards pine oil, you can get this fairly cheaply on ebay(in 100ml amounts). Another alternative -- which is slower acting but still pretty good -- is pine bark extract. Don't use Pycnogenol extract -- it costs 3 times as much and I don't think its as good as pine bark extract.
I'm just throwing stuff I know at you as alternatives just to help you with your problem...
Just to clarify -- I'm not really talking about Wormwood. Artemisinin comes from Wormwood which contains only small amounts of Artemisinin. So if you do buy it -- don't buy the Wormwood but be sure to buy the pure Artemisinin capsules. This is what you need.
The other protocol that might also help you is to supplement borax(Sodium Tetraborate). Borax is one of the few nutrients that will kill mycplasma and mycobacteria. And if it kills mycoplasma(a CWD bacteria) then it will probably kill Whipple bacteria. Another substance that also kills mycoplasma and fungus is Hydrogen Peroxide.
If you want to look at my full protocol against fungus and Candida -- it's here. My protocol will also kill and remove other pathogens that are always usually associated with candida -- like mycoplasma and parasites.
