I live near there. Carmel is now a very nice place to live, easily the nicest place to live in the State. It has very impressive walkable areas, tons of new restaurants and shops, the best schools in the state. It has become easily the most desirable place to live in the region, and good jobs have followed that.
>Things typically become labeled "medicine" when they've been work and have been tested
Eh, sometimes. But often things labeled "medicine" are things that companies can get FDA approval for, patent, manufacture, ensure shelf stability, label with a brand, and sell to customers at a high margin. There are lots of plants that are proven to work but aren't sold to customers because they can't meet some of those criteria. They aren't necessarily worse, just can't be be sold at scale profitably.
