As long as the plants are studied and documented with open studies, available to the public and published in real papers. The moment when science can't back a specific plant's benefit is where most people are lost and other people are conned. Regulations are also made to be bent, as nowadays there are more nutritional supplements promising complete body rejuvenation in commercials on TV than any other product.
I hail your job and the work you are doing, needs more promotion to the young students. Education is also good for science in general!
