While governments love to waste taxpayer’s money on a lot of inane things, they haven’t quite sunk to the point where they’ll waste money to fund the use of crackpot herbal cures and snakeoil. The reason laymen shouldn’t waste their money on most of the stuff is because the vast majority of overpriced products fall short in important catagories:
1. wild curative claims have NOT been confirmed by scientific/clinical trialing so the efficacy is dubious- does it really work, how much is needed, what happens if you take too much (television informercials are just modern snakeoil pitches; they often get around FDA fraud restrictions by slapping disclaimers on the bottom of the screen in print so tiny you need a magnifying glass to read them)
2. little or no rigorous quality control standards govern harvesting and production (you don’t know where it really came from, what chemicals might have tainted it, how much IF ANY of the magic ingredient is really used or even whether it’s mixed well to produce uniform amounts in each serving)
As with many legit supplements and even name brand vitamins that gullible laymen swallow because an advertisement sounded great, at best, self-medication with herbs often just creates expensive urine (because the stuff flushes out unmetabolized), but at worst, can be toxic.
There are many examples of product recalls that occurred only after the FDA finally got round to investigating the crackpot claims made by fraudsters. e.g., coral calcium (false claims, hype, plus uncontrolled harvesting damaged coral reefs), dehydrated veggies (bad quality control - no proof it had veggies and not just leaves raked off yards, contained a lot of insect parts), etc.
