Much of our existing medicines come from scientific study of herbal medicines, and I do not think we have yet fully tapped that source of knowledge.
Additionally, I think there are many cases where an herbal medicine is a like 50% effective solution compared to modern medicine, but less than 10% the price. Many doctors may not even be aware of such treatments.
One non-herbal but older than modern medicine treatment I am aware of is soaking cuts, punctures, etc in very salty water to disinfect and help it close better. This is exceedingly cheap and helps ensure wounds never get infected.
Furthermore, this kind of tech requires expertise that is not easily decentralized. As such, it tends centralize power and control of one’s health in a civilization. The civilization needs to educate and produce a few to be able to serve the many, leaving aside the number of tech dependencies in order to produce facilities that produce this, let alone the research organizations to continue studying this stuff. It does not make for a resilient, anti-fragile civilization.
This isn't a choice between "cough medicine" and "slightly less effective cough medicine", it's a choice between a controlled and inspected product and random plants that may or may not be the right genus, dose and concentration.
If lack of finances is an issue, growing your own herb garden certainly isn't the solution. These plants aren't going to replace a $500 shot of insulin. At best you could maybe replace the occasional aspirin, dramamine, or buscopan, all of which are available over the counter at price points much lower than what it would cost to even buy a bag of quality seeds, never mind soil, fertilizer, and the garden to plant it all in. (Or the time and labor to plant and tend it).
eg. Chamomile - still used for bad stomachs (is a costive), whether it works on herpes simplex seems really dubious.
Often modern medicine is based on these plants. And of course there are modern treatments that go way beyond what we were able to achieve with just plant-based medicine.
