People are afraid of natural alternatives because they are usually not backed with a metric tonne of scientific evidence and study.

Do you really think if something natural actually worked that the big pharmaceutical companies wouldn't try to find a way to isolate the working compounds and make money off that too? They would try to discredit the natural alternatives while trying to isolate and make a profit This isn't a dig at your products or products that have countless people praising them, it is just my two cents on the issue.
