Herbal Products?

Why do many people now start consume  herbal medichine? where does the ability of artificial/ sophisticated medicine that we must take a college to make it?
on the contrary some people in society they preffer to think of the ability of natural recepie. how come doctore just let them do so ?

or the docters also do not trust anymore to the latest technology that produce artificial products (medichines)?
as we know start from long time ago multi level marketing also have introduces herbal products to society.

as some shop in thamrin city also starting to sell many herbal products from other country or even from indonesia it self.
