Because they ARE cheap and are not as profitable for Big Pharma as their prescription-only meds... which will probably turn out to have Benadryl too, but also a lot of other contaminants that no sane person would ingest.
The same thing happened many decades ago with Lithium Carbonate. LC is one of the most abundant minerals on Earth and it was found to treat bipolar conditions quite well. But no pharmaceutical company would touch it and do the required clinical trials to bring the substance into use, because there was no profit to be made.
It was the Veteran's Administration (back when government actually worked for We The People) who did the clinical trials and got LC approved for use with bipolar patients. Since Big Pharma did not invest anything in clinical trials, they were then free to market their own versions of Lithium Carbonate profitably.

How our world works in one easy lesson.
Yeah I know.
I was being facetious
Heh, I know, I was just making a point about Big Pharma and the profit motive.
The FDA is banning them because they do work.
