Alternative treatments

Has anyone had any luck with Essia tea or mistletoe extract to treat this type of cancer or anything besides chemo? I think my mother-in-law's cancer has came back and if so I want to do as much as possible to help her.  She tells us she won't do chemo again and she's not a candidate for surgery. 

I belong to a cancer support group following diagnosis/surgery for esophageal cancer, and some of the others with different cancers and they go to a physician who specializes in alternative medicine and take different types of herbs which they feel have helped when the cancer returns; maybe you can check for Holistic/Alternative Medicine near where you live.  Good luck to you and your mother in law.
