Yes, I tried the parasite herbs but they were WAY too strong for my leaky gut and I had to stop them after a few days. I am hoping to get rid of all my "critters" by cleansing my body ( ie., liver, bowels. ) Sorry you had no results with the flax oil. Yes, it's probably better to stick to the more traditional oils for flushing. I tried the grapeseed last two times and it was a lot easier to get down than the olive ( Yuuk! ) :-)
