I noticed that literature said that Moxidectin did NOT work on flukes. However, when I took Moxidectin I felt them all release their bite. They bit back down later though. I get rid of a lot of junk in my intestines following that, but I also have a mixed infection and I can't say what came out. I do know I have TONS of things still biting onto my blood vessels sucking off of me still. So I can verify the Moxidectin has some action, but I can't verify it killed any.
