If a person does a liver flush after 5 days of the dewormer and really looks in a bucket as they clean it with lots of water, they may see worms, if they know what to look for. So odds are, few, very few will actualy ever see a worm.
Getting hot after taking herbs? I would assume bacteria are being killed off and circulation speeds up to eliminate the acid waste as well as the herbs/foods.
I suggest 1 with each meal, then 2, then 3, etc. until you hit that perfect number and as things get stronger you reduce and reduce until you have corrected your diet and never need the LBB again.
