In the end I was able to order a custom blend off of Perfect Herbs (it's a Canadian company, as I am also from Canada) through my naturopath. My naturopath was able to add 8 different herbs all together in one blended equal parts tincture.
WalkingByFaith, As for the powdered Japanese Knotweed, I might try that later on as a long-term 'maintenance' herb.
Take care guys
