I think the @naturalmedicine initiative is a great way to make a difference, Sharing the knowledge and elaborate on the knowledge. From plant to mouth, teach and explore. The more knowledge there is among the people the more the people will use it.
That then shows what works best. And humanity will grow a technology around it.
Don't forget that the royals themselves use a lot of homeopathy. So just by using what works, and sharing that knowledge, we will get to the next stage.
