They are much more predictable, well understood and easier to dose than the chemical cocktail of natural compounds. Please note that I am not saying that there aren’t any useful natural medicines. I am stating that it is better to isolate the active components.
Well… idk where you are from but here doctors would recommend natural stuff where applicable. And many times there are actual remedies made based on natural stuff, as you say.
By saying I prefer natural based medicine I don’t mean thay when I feel sick I go pick herbs by the moonlight and only use that.
