David said: It is easier and much lazier to be negative about things you are ignorant of, than admit you are ignorant. I have had Dolores tell me in medical school they were told never to admit ignorance, that is too bad. No one knows everything and no matter how much one knows it is a fraction of what there is to know. Detox pathways are fine but many pharmaceutical medications and herbs do not work that way, there ar eco many mechanisms of action. The nutritionist is showing her ignorance. Of course it can be frustrating to have people who know little or nothing of herbs dismiss them, but it is equally frustrating to hear people making ridiculous or unrealistic claims of cures. If you become knowledgable you will be able to help people, many who have not found help anywhere else. That is incredibly gratifying and there research that is published the more traditional herbal medicine is proved to be valid and often quite effective.
