As far as I'm concerned you're being religious biased against the Christians. What I don't understand is why dragging christians as a religion out of this? And what happened to other religions?
I'd contribute to this without dipping to spiritualities.
What we serves as our God or deities isn't what preserves our lives but to guide individuals on different perspective of living with different believes.

Op, I don't know if you mean herbalist or the so traditionalist because I don't see potential additional lives in traditionalists but if you mean to say the herbalist then that would be considerable in the sense that the herbalists are most comfortable consuming more of herbs in ligns of taking their foods through herbs that are medicinal to keep one fitted and healthy.
This is to say they're common and exposed to herbalife which has the anti unhealthy potentials. So this could serve a medium to safe lives or keep lives living to a high extensive esteem.
I'll advise you keep religion out of this Op.
