I was just checking out this tribe because I received some lotus tokens in my SE wallet. I wasn't sure whether to stake them or dump them. I was a bit skeptical of a tribe based on natural medicine for the reasons you mention at the start of this article; there are lots of unverified assertions and ridiculous claims within those communities, and they tend to mix in some "spiritual" nonsense as the cherry on the bullcrap sundae.
But this post made me decide to give the tribe a chance. Natural medicine and prevention can be good things when they are based on scientific evidence.
