Certification in anything is no guarantee of reliable and trustworthy advice.
I have no credentials in health related matters, but do have over 30 years of accrued knowledge through study of Natural Hygiene and water-only-fasting, where some refer to me as an expert in the subject.
My best friend has no formal qualifications in Computer Sciences, but holds a post as a Senior Hardware/software Computer Technician, in a global network within a large UK based company becuase of his knowledge and experience.
Opinion on what is a "quack" is weak. Any profession that requires standardization such as certificate or degree is merely a statement of completion of course-work. Licenses in a field are both permits to work in the field and a form of control to stay within the boundaries set forth by the organizations that control the licensing requirements.
Thus, regardless of what is quackery, some of the most successful people have been drop-outs (Microsoft and Facebook founders to name a few).
By definition a quack can be described as......
"An untrained person who pretends to be a physician and dispenses medical advice and treatment".
Therefore someone who has had much experience in their chosen field cannot be described as a quack because they have acquired their knowledge and training through this experience and therefore can be described as "trained" in their specialty.
A certificate or degree only means they have reached a certain standard of this acquired knowledge through study, whether this be manually or academically.
I agree with you that a licence in a field is a form of control, so that true charlatans cannot be let loose on the public by giving ill-informed and inaccurate advice, but where this advice is based on a wealth of accurate knowledge then credentials are largely irrelevant.
For example, I offer advice on water-only-fasting based on what I know to be true and accurate information gleaned from the past 150 years, and do not see the need for credentials to rubber-stamp that accuracy.
Personaly I think people should be there own doctor, once diagnosid, get to the source. detox pollutants, kill parasites, then focus on area that needs support. sooooo many cures.Sooooo many herb combinations. herbology is interesting, fun,anyone can do this. Drugs are a last resort. If an herbalist told me what herbs to take, first I research the herbs so you know what to expect.
im sure there are quacks out there, but if you know what works......what can I say.like anything experinent. when a doc gives you a drug theres no guarentee its going to work.
Herbs are for anyone to learn, there is no real school for this. Someone is is a certified herbalist through a 6 month school, college can train anyone to be an herbalist or natropath, when that person feels his ,hers student is ready, they can call themselves an herbalist.
I use alot of herbs personaly, tell people what I know, read alot of books,I dont call myself an herbalist.
I do know an herbaist here in my town, has a herb shop, does well, He learned this way but dont think he has a degree or certificate on paper, but if someone wanted more info on this man they would be directed to the certified herbalist who trained him.
As far as I know that the way it is..
Dr Clark is on the quack list, Do think Im going to go by this, If it wasnt for her Id be going blind with macular degeneration, among other things, she's saved countless lives, yet she's on the quackwatchers list created by drug pushing. I hate those people. As much as I dont like saying go to hell to anyone, I cant help but feel this way. These people are on my list.
