I think herbs and plants have a part to play in health for sure. Especially in the form of diet to prevent disease in the first place. That being said the science and chemistry is very interesting as it can show why plants have certain effects. I think somewhere in between is the sweet spot that we haven;t arrived at yet. Some plants have many chemicals that act in synergy. Some day I think pharmaceuticals might be 3d printed with many chemicals in one pill to address different issues in health unique to each person. Oh almost forgot, pumpernickle lol
