can I buy it at wal mart or anywhere or is it special horse type? I am going to be ordering Jherb, too -- maybe? My Cinderella's sweet itch is really bad. I started APF a week ago.....now going to consider adding these items to a tight/balanced diet. What do you think? Is this overdoing it? What am I doing????? I can't imagine there is anything else for me to give this poor girl:( Julie and itchy Cinderella
