Please click on the links to learn all about the basic ingredients (you might end up learning more than you ever wanted to know)! Many of these links go to a Squidoo lens I wrote all about Knowing Your Ingredients, so if they look different than the “normal” PCO stuff, that’s why.
Want to learn more about an ingredient? Want to know about an ingredient I haven’t covered yet? Leave a comment below and I’ll be sure to add a page or three for you.
