Yes, what do you think they make modern medicine out of? Most of the time a plant is the base for it.

I think 'yes' is too broad a claim.

Modern drug discovery is far more complicated than that.

See my other comment. But where they don't I'm sure they make a fine placebo.

I'm not willing to say all of these "cure" but most modern medicines take an active ingredient from a plant and synthesize it in larger quantities. Some of the one listed here are ones I do myself. Mint for nausea, chamomile, and lemon balm to sleep for example.

It'd be nice to have some linked studies, wouldn't it?

It would be nice but factoring in costs and profits I doubt that will happen unless some curious and incredibly wealthy philanthropist contributed to some research. About 15 years of experimenting on myself has bypassed my own personal need for studies and I am entirely off all prescription medications. It was not easy and I made a few mistakes along the way, but have very few regrets.

I think the better frame is not to see this as the plant acting upon the disease or symptoms, but rather, assisting the body’s own natural capacity for regeneration and healing.

They don't cure the illness, they only help to treat it. Generally herbal medications are milder and need to be taken for a longer time. I find they can be fairly effective. Sometimes, though, what people say should work doesn't work and you need to go find something stronger at the pharmacy.
