For well over a year, I took 8 drops of oregano daily, added 1 drop to every gallon of water I made and had what MH added to a bunch of his formulas that I took. It didn't touch the beef tape worm that I had. For some reason, my body told me to take large amounts of Dewormer (I do not remember how much, it could be found in a post in this forum); on day 10 of doing this, I started passing pieces of reddish brown segmented tapeworm.
