Well, he provided you with a source about the ideology. Other sources could be of not much use for you, being in German (as it turned out to be). Yes, you can fool around with Google Translate, but generally, you normally wouldn't want to post links to German (or any non-English in general) sites on an English forum unless you're linking to an image (or something similar that doesn't require understanding of the language). It just seems improper, even if we're talking sources to back up a claim. It's like talking to someone in a language other than everyone around you. Assuming neither you or the person you're talking to has difficulties with it, it's usually preferable to switch to the language spoken by everyone else around.
He is a proponent of new germanic medicine, which you can read about here here: https://en.wikipedia.org/wiki/Ryke_Geerd_Hamer and which should tell you everything you need to know about his scientific credibility.
Sounds like one of those Nazis who proposed "Aryan physics" to replace "Jewish physics" back in WWII. Didn't work out then, either. Especially since it involved rejecting a certain slightly weird theory from one very Jewish physicist with messy hair... Heck, the guy who invented this even proposes a Jewish conspiracy behind modern medicine! Call Godwin's law all you like, but this guy really does sound like he'd be a model Nazi if he lived 70-80 years ago.
Or maybe the "Aryan physics"
did work out and they invented time travel back in '44... That would certainly explain people like him very nicely. They're some 70 years too late, though, those ideas went out of fashion somewhat. I wonder why can't they put him and his quacks in jail for endangering people with their "treatments".
