"trouble with the herbs tho, is that you cannot acuuratly decide on a dose, since the amount of active ingredient will vary from season to season, because of the growing conditions.
And since it is the active ingredient that matter, rather than the herb per se, isn't it better to get it in a know amount, of a known strenth, with no unwanted additives?"
Just in case this was at all in response to my post talking about someone developing a knowledge of herbs being a scientist (I'm not sure, sorry) - I wasn't arguing "herbal medicine is science => herbs are just as good as modern medicine". Rather, I was trying to make the point that herbal medicine can be just as much science in action as yer classic white-coat medicine, and therefore it doesn't make sense to make arguments of the kind "herbs are good and science is bad".
Science is what we all rely on constantly to separate the effective from the ineffective, to work out how the world works - right from when we're children learning by experiment how much of the area of a book, say, that you need to keep on a table to stop the whole thing falling off (learning about centres of gravity by trial and error). 'Reverse-cherry picking' some aspects of science to reject, while deep down relying just as much as anyone else on scientific principles elsewhere (even within the development of supposedly 'alternative' therapies themselves) makes no sense (and is quite hypocritical a lot of the time).
