I was brought up by a mother who believed homeopathic medical products were more "natural" (probably opposed to "chemical" or "artifical") and it took me 20 years to reconsider this stance.
**Why?**
Quite simply, I never actually reseached what that word even meant. It was always framed as "homeopathic = good" and when it is presented as a fact for so long, you basically have to actively start investigating. Especially considering homeopathic products are covered by German health insurances for various terrible and mostly historical reasons, which a whole admission process existing in parallel to proper, science-based processes.
This whole thing is comparable to how specific "trendy food" is often considered healthy by default Yes, there are in fact scientific reasons why spelt flour has its advantages but buying cookies made with spelt flour is still a mostly un-healthy thing to do.
The only thing to do is to tell people, getting the message out there. Like sharing videos like this one (german):
