IS IPT CHEMOTHERAPY ILLEGAL IN THE US OR DO MOST CHEMO DOC PERFORM THIS KIND OF CHEM?

MY MOM HAS STAGE 4 COLON CANCER, AND ON MEDICAID WHICH MADE IT DIFF TO FIND A GOOD CHEM DOC. THE DOC BEDSIDE MANNERS WHERE HORRIBLE BUT HE IS THE ONLY DOC IN THE AREA THAT WILL TAKE HER INSURANCE SO I VE BEEN GIVING HER HERBS LIKE MUSHROOM EXTRACT, NONI JUICE, VITS, IRON, WHEAT GR AND TRYING TO KEEP HER HAPPY. SHE GOES TO HER DOC TOMMOROW AND I KNO HE WILL RECOMMEND A HIGH DOSE CHEMO AND HER BLOOD COUNT IS 7.5 AND SHE REFUSES BLOOD TRANSFUSIONS DUE TO RELIGION. HAS ANYONE EVER HAS IPT CHEM OR KNOW SOMEONE WHO HAD IT AND WAS SUCESSFUL. ANY ADVISE WOULD BE HELPFUL?
