I used 2 drops of nascent in 4 cups of distilled water. It is the one from LL Magnetic Clay, a very good Iodine actually. I am not sure the strength compared to the Lugol's though.
I was doing a whole lot of things to get rid of those critters. I have a video at youtube, actually two of them that went through what exactly I was doing. If you are interested I could send you the links. It's just a whole lot to type so it would be easier to check out the videos and see if there is anything you could incorporate into your parasite cleanse. =)
here is that link. you can find another one on product suggestions as well. I actually did these videos for my family and friends so I suggested they do this 3 momths but I went six. I was using some other products initially that were not touching it though.
