The good news is that if it did come from you, it's out!
However, you still want to cleanse for parasites. I did a parasite cleanse a few years ago that seemed to be effective. I filled gel capsules with castor oil and froze them and took them internally. I remember feeling something really weird moving around inside after that. I think I did castor oil packs too, with the instructions according to Edgar Cayce .
A few days later I had a phone appointment with someone who does Emotion Code work (not sure if I believe in it). However, he did some kind of reading on me and he said he was really surprised that I have no parasites, because everyone has parasites. I thought it was odd considering I had just done my first ever parasite cleanse and he did not know that.
I can't recall exactly what I did other than the castor oil frozen in capsules and castor oil packs but from what the guy above said, it appeared to have worked.
I also do not eat pork ever, or meat, so that might mean I don't have as many parasites as most people.
