Hello Patrick.... I have no personal knowledge about the Denmark Clinic but I would suggest to you that wherever you are located you should not have to travel far to find very effective natural/alternative/complementary treatments.
Here is a website that should be helpful for you. I believe it begins with a patient's comments about the clinic you mentioned but follow the links and you should find comparable treatment choices closer to your home.

I personally have been using only alternative/complementary treatments with great results and if you'd like to know about my experience please send me a private message.Best regards
Shemay
