Indigenous "weeds" of southern AZ.?.?.?

[RotaryPowered]

So I was looking for AZ specific insight on indigenous weeds for benificial properties. I see lots of weeds out where I'm at so what better purpose for them than to ferment them in turn making nutrients, fungicides and pesticides. So on that note anyone ever made a concoction that was promising, or has anyone found an index on indigenous weeds that was helpful pictures and all?

Any info appreciated, Mark
