I hope it's not too tragic like here on Earth where entire species are being poached into extinction because "Traditional Chinese Medicine says it improves stamina!" There are likely all sorts of folk medicines, though I'm willing to bet that 99% of them are placebos, superstitions, and downright scams.

Not at all like the Lalafellin miracle elixirs you'll find at my cart!
