I'm not getting into this discussion, but I can tell you that the average person cannot get through scientific studies and understand what's going on .
My father was a pharmacist for 30 years, when younger I'd read his pharmacy journals, sure there's lots of new drugs and stuff tried but this is generally for specific treatments.
I had chronic dry mouth post surgery, my father had received a sample of horizons I think, well It cured me!
I had terrible psoriasis for years (probably from all the wine ... No joke, once I cut down alcohol my face got better) anyways, a dermatologist friend recommended sal3, sulfur dioxide soap and boom that worked better than all the RX stuff .
But that's not a controlled scientific study, it's just random stuff that worked for me... Where it never hurt to try things.
You can challenge medical science in ways, but ironic that the warnings of taking various medications like hydroxy are shrugged off, while they will scream at how vaccines kill.
I recommend the book "trick or treatment"
The average frum person absent a secular education should open their mind to how medical science evolved.
