Sir, My mother is suffering from cervix cancer (IIIB).She already took 25 250c gy radiation with weekly chemo(cisplatin)& 3 brachytherapy treatment ,now some symptoms like mucus black stool has been seeing for 5 to 6 times per day for which she is taking the OFLOMAC OZ medicine.Sir i heard about graviola flowers (soursop) which is used as juice to kill the cancer cells directly,but providing some of the side effects such as parkinson's disease and damage to nerve cell.So then what should i do? (my question is whether i should give it or not? )if is it okay to give then what should be the dosage?
