This really is the crux of the matter. On the plants list, the lack of 
bottle/manufacturer information was discussed at some length and 
severely criticised. 
I often think that the plants list guys are more on the ball than any of 
us, not because they are more interested/expert but because they have a 
fixed set of parameters to work on, curled leaves?: look at calcium 
etc.
We, on the other hand, can sometimes believe in things without 
necessarily having proof of its efficacy, because there are _still_ so 
many unknowns; vitamins, acids and extracts etc.
Personally I'd go with what Eric said (he's _much_ more knowledgeable on 
these things) and call it 'snake oil' until someone reall has _positive_ 
proof of its benefits.
