well,
you extract them for several reasons:
a) you get pure product. If you are using rue for example there are two other alkaloids in the seeds that you can get rid of by performing the Manske step in the extraction. This is good because these alkaloids are utero toxic and I think might also cause nausea. And if they don't then the rest of the plant matter or what's in it does. so the extract will give you less body load
b) the extract can be used for changa
c) if you use extract you know with much better accuracy how much you are ingesting, provided that you performed the extraction well and cleaned your product to the best of your capabilities - then you can expect you are ingesting the amount that your scale reads out...
hope this answered your Q.
cheers
Enoon
Buon viso a cattivo gioco!
