Yes, anything that works but can't be patented they'll call it "unsubstantiated claim". I suppose Pharma's dream is to make all non-patentable medicines unavailable or illegal. https://twitter.com/ColleenHuberNMD/status/1303088180917186560?s=20

The case of vitamin C is especially amazing in that its well documented use as treatment (beyond the scope of a vitamin) has been effectively hushed, practically disappeared, and the FBI will in fact raid clinics that use it intravenously. All institutions work for Pharma now

I'm going through some papers in the site mentioned on this thread.

I like this anecdote about a mother taking "things into her own hands" to treat her gravely ill daughter when the doctor wouldn't . This is in the Klenner 1971 paper.
