you know, I have no idea anymore - liver/thyroid - whether the chicken or the egg came first. I guess it can't hurt to work on them both. I'm wondering if it's possible to ever completely eradicate parasites, I've done plenty of that type of cleansing, too, but I have no idea whether any came out with the flushes. I'm pretty sure mine are mircoscopic, more the protozoa variety, so I wouldn't see them anyway. I looked close on most of the flushes, too.
