I mentioned apples as an example of how Nature provides us with nutrition in certain packages. Every part of it has a function and a role. Similarly with medicinal herbs.
Are you claiming that certain herbs exist only to cure human diseases? What bollocks. If the function of a willow tree was to provide pain relievers to humans, it would have the pain relief chemicals in handy little pouches in regulated doses.
The function of an apple is to spread the seeds of apple trees far and wide. The fact that it tastes nice is a happy byproduct of the species' chosen method of dispersal.
The second point is about Science being a part of life all through history. Though perhaps not named and categorized as such.
No doubt technology has developed very rapidly in recent decades helping medicine and other areas of science to also develop rapidly . But that does not mean we can create artificial and distinct divides between so called 'traditional' and 'modern' aspects of life. As though they are two different worlds.
Skepticism, suspicion, doubt and scorn for everything that is traditional, is dysfunctional. Life is a continuum with no discrete breaks. Integrating traditional practices with modern methods is the way forward.
People don't scorn traditional things. It's just that modern science can take traditional cures and a) find out if they really work or not and b) refine the active ingredients so that they are safer and more controllable.
