You give us the essence of anecdotal reportage and also show why anecdotes cannot be substituted for knowledge.
There is no way for me - or for you yourself, for that matter - to know whether the herbs you took helped you in any way. You don’t say - and I assume you don’t know - whether other factors were involved. What about other medications, prescription, OTC, or herbal, that you might also have been taking? Did you make changes in your diet? Does you exercise more? Reduce your stress levels? Gain or lose weight? Stop or start smoking, or drinking, or taking illicit drugs? Any of hundreds of changes in your life could have had an effect instead of or in combination with these herbs. We’ll never know and neither will you.
A good clinical study will try to reduce or control for these other factors. And it will group the results from a large enough number of people that the varying factors will balance out or be submerged and the true effect of the drug shown, at least to a statistical significance. Remember that even in failed drug trials, some people are always helped by the medication. The proper question is not whether some particular people were helped but whether a large enough percentage are helped so that mere chance can’t be the sole factor involved.
Your report shows why anecdotal evidence is literally valueless. If a hundred more people were to come in and give the same glowing take, it wouldn’t make any difference. 100 valueless statements don’t magically add together to a worthwhile one.
The underlying problem is not with the effectiveness of any particular herb. It’s that people simply don’t understand why anecdotal evidence needs to ignored. I have no way of knowing whether your experience means that my experience will be positive, negative, or neutral. I can hope that a clinical trial gives me some basis for knowledge. Even there, the results of many clinical trials are overturned by later - larger, better managed, or more focused - trials.
If that’s so, why do you think that your individual statement of selective information should sway my behavior?
I repeat my earlier statement. Don’t rely on anecdotes from anybody. Clinical trials are the best information we have, and even those should be evaluated carefully to study whether they properly apply to you.
If this means throwing out the entire herbal industry, so be it.
