"You don't know that you don't know."
This is one of my surgery consultant's favourite lines.
To be honest, he doesn't know that he doesn't know anything about natural medicine. That coconut water has some very healthy properties. That cod liver oil doesn't make gallstones but prevents them. He teaches his patients and students wrongly when they ask about simple natural products and supplements. Too bad for him. I know better.
That's all I'll say here. You can read more about this and a bit more about cod liver oil on my natural health blog: here.
