My Mom has Colon Cancer - info

first, I would like to thank Monika, Lisa P., Sue, Steve, Jen, Julie and Judy (grandma047) for all of their encouraging words! All of your messages really made my week.
Has anyone tried herbal suppliments? or seen a natualpath?
My mom has only a few more treatments of chemo and the doctor's are about to give up on her. Last week we got more bad news that the chemo isn't working anymore and its just making her really sick.
Some people swear by different herbs and I was wondering if anyone new about those that have worked.
