Actually, its original meaning is more like "stuff extracted from living things, which may not be the domain of the same science as those "chemicals"." When the term was coined people didn't *know* what organic stuff was made of, and it was possible to believe it wasn't the same as the inorganic ones - elan vital wasn't *always* quack science. The modern equivalent might well be closer to "biochemistry" than what's called "organic chemistry" now. Or perhaps to creationist rhetoric about unsynthesizable biomolecules (you know "scientists can't make sugar..." though that's been false for a very long time now) and irreducable complexity.
