Serious question, how did “ancient peoples” figure out supplements etc when their dosages weren’t standardized or the results weren’t short term?

For instance I started Tongkat Ali in end of January and I’m not noticing anything. Bit some people are saying “it can take a couple months to feel it”.

Ok but I’m buying some “high potency” standardized, highly processed, amazon delivered bottles, but theve mofos were doing what? making tea with grinded up plant product and then committing to that routine for a couple of months, not knowing what to expect, and then suddenly thinking “gee I’m hornier and stronger than I was a couple months ago!”

Lmao I hope you guys get my point.
