That would be "natural." Hippies (I'm a long-time extreme ex-hippie) have wiped their asses with this word. The word is meaningless; just because something is natural doesn't automatically mean it's good for you. Here are some natural things: volcanoes, earthquakes, tsunamis, cocaine, tobacco, cosmic radiation, poison mushrooms, mercury, arsenic, bolts of lightening, predatory large animals -- all these things are 100% NATURAL! And all of which are quite capable of killing people.
