Liver flush without Epsom Salts???

I hope someone can help. My boyfriend is very against me consuming epsom salts at all, because he's read about some people who have died from eat epsom salts. Does anyone know a recipe that I can do minus the epsom salts? I'm about to embark on taking humaworm, but I don't want to do it without flushing out all the critters! I would greatly appreciate your thoughts. Thank you! :)
