oregano oil is imported from turkey. it is not made from the stuff in your pantry. you can buy it from the health food store but much of that is diluted. buy the pure stuff from MH, the barefoot herbalist. thats where i get mine.
to make silver you can buy a machine or make your own set up. its not difficult but you do have to know a few things. i just did a recent thread on it or go to the CS forum. this old post can be found there. its not perfect but it will get you started.
