China likes to claim that they were an advanced civilization when we were still barbarians (well, actually, they still think we are).
Their ancient herbal medicine was thought of as backward and useless for much of the modern era.
Only in recent decades have many herbal remedies and acupuncture been proven to work and accepted by western medicine.
One reason that acceptance was so long in coming is a refusal on the Chinese side to accept that some of their "cures" are not only worthless, but manufactured via unacceptable practices.
Rhinoceros and Bears are still killed for body parts that have no proven positive effect.
In China, there are even "Bear Farms" that cage Asian black bears in tight quarters, deny them adequate water, and cause and leave open wounds in order to harvest bile from their gall bladders.
