Although I never heard of scattering of parasites with herbs (I do think this is what RG was referring to, rather than not knowing about wandering parasites like Ascaris), the original post is informative and a consideration. I've seen other posts where people have stated the same about herbs. I could be wrong, but I don't think the "attack" or "vendetta" is against RG personally.
Before the "system crash" and wiped out some pertinent info on the parasite forum, 1/2 of the respondents claimed that meds were responsible for scattering and 1/2 claimed that herbs were. I think this was an interesting notation and to think about.
