I have spoken with Dr. Eckle’s he has a clinic in Seattle Washington. I had a free consultation with him last fall (2020). He does lots of testing for heavy metals etc as well as the treatments mentioned in the book blurb. I didn’t proceed with treatment at his clinic mainly due to the Border closure and the unfavourable CAN -US dollar exchange which makes his treatments very expensive and I can’t currently travel there.
I was able to find a naturopathic doctor in my home town who has a similar background in Chinese medicine and he was able to obtain the same tests that Dr. Eckle uses . He has been very helpful to me and I find his remedies do help and paying him in Canadian dollars helps the bank account.😀
