Talked to an N.D. Today

So I had an appointment with an actual naturopathy doctor. I live in Clarksville Tn BTW. He took a saliva sample and after looking at it he said that I was in pretty good health. I asked him if I could use a Liver Flush and he told me that I didnt need to and that he recommended not to because it could actually weaken my body, temporarily of course. Also he did not charge me for the visit.

Should I look into doing one any way? What do you all think?
