I need to add,
Every herbalist has good products, and there are faithful people that are going to defend them no matter what, I've seen it on Barefoot's and I've seen it on Humaworms.
I think it's like alot of people have said here on this forum, it takes some of our own experimenting too. Maybe "normally" infested people get by with 30 days (which is what Barefoot also recommends- but he also recommends maintenance of 1 TB a week after that, which would never have worked for me either.) I'm not "normally" infested, if there is such a thing.
I think there's alot more people with tape worm problems that aren't finding them because they do quit.
