Hey, I'm gonna play devil's advocate here because I'm also scared of meds.
I've been taking the NOW foods Black-Walnut / Wormwood tincture, eating paleo, and drinking a bit of acv with each meal. I have gotten some things out.
I am about to COMPLETELY follow Brenda'w deworming protocol (go to realfoodsrebel.com).
She was sicker than both of us combined and claims to have gotten rid of her parasites.
Her protocol is also somewhat similar to Onwards (look them up, was a user of this forum).
I will warn that brenda added a bunch of supplements that you probably can't swallow, but the main information seems really good. I am going to try this immediately, since I think NOW foods product is too weak for me.
Since I'm not yet crazy sick, I want to exhaust my options with herbs before I try to take any meds. I highly recommend giving her site and Onwards' posts a read.
She also references the work of Terry Wahls, who was an MD disbelieving of natural medicine until she got MS--and then proceeded to put her MS in remission with SIGNIFICANT diet changes (see the Wahl's protocol).
Anyway I obviously cant say that any of this will work definitively until I do it, and even then it may not work for you, BUT I just wanted to tell you that there ARE people out there who claim to have dewormed/parasited themselves WITHOUT drugs.
Even if you eventually do the drug route I think it's worth giving them a look.
