The mirror you found in Aleroth. Did you happen to get the healing gem from the shrine? If so, you were supposed to duplicate the gem, and heal both the soldiers. (if you drop the mirror and the gem into deep enought water, the mirror will duplicate it)
The purple (you can buy this in the wastlands as well) and the drug made from George's plant both raise you stats, though i can't remeber what. Check out the Alchemy spoiler thread for what they do. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
