if i look at his cv, he has for sure more knowledge about parasites than many MD's.Some american MD's do not even deserve this title, i am very disappointed about many. Sorry to hear his herbs did not work. Maybe you should do some testing,just to be sure you have the right stuff. I would test at different places, i test through my insurance, then separate labs.Did you write him and ask him his personal opinion and tell me herbs do not work. Just complain about it,maybe he has other ideas. http://parasitetesting.com/_private/professional%20resume.pdf
