'What Mr. Leminick is referring here to as “evidence,” or the lack thereof, is the randomized, double-blind, placebo-controlled, human clinical trial (RCT).
The RCT has become the epistemiological holy grail of Scientism and the Medical Monotheism it informs. In this belief system, it doesn’t matter if something has had cross-cultural validation as a healing agent, even after thousands of years of safe human use; nor does it matter if you personally have experienced (N-of-1) direct and measurable health benefits from consuming it.
This is essentially a pyramidal control system: the RCT situated on top, and your first-hand experience and associated “anecdotal claims" on bottom, completely worthless. What's considered 'really real' is what has been externally validated through the RCT.'
