Many people will not use common sense unfortunately.
Cahill is the most wonderful doctor I ever met, the only one doing test for a series of parasites in the way the best books tells one need to go ahead to test for these parasites to have good chance finding them (if infected)....
Have in mind some of these parasites, like Entamoeba Histolytica has long healing period...if diagnosed with it, then it will lakes months to heal even 80%...but when you are deadly sick and get 80% better even it is wonderful....and then one just get better and better.
Cahill is a unique doctor. I was shocked when I read basically all the big books on infection medicine in detail and figured out non of my other doctors had tested me properly for parasites....I was so lucky I finally got in contact with Cahill that quickly gave me right diagnose! and then I was on to my way to full healing....
