I have liver flukes and it impacted them by making them all detach from my blood vessels and putting me in a dangerous situation because suddenly I was bleeding internally. I was very sick. It was dangerous. I was practically (if not actually) in shock. Don't do it if you think you have liver flukes. Don't. Don't. Don't. It didn't kill my liver flukes. It just cause them to detach and I lost blood. The liver flukes reattached again.
I don't know why they detached. I supposed they didn't like the flavor. But it certainly didn't kill them.
