Are the main customers for items like this the poor and uneducated, or the wealthier segments of Asian society with plenty of access to modern scientific knowledge? Also, I wouldn't be surprised if it's analogous to the Dr. Oz / anti-vaccine set in the U.S. Those people have access to all the knowledge they could want, but you still couldn't shake their misguided beliefs out of them.
