I have seen quite a few success stories for Low Dose Naltrexone (LDN) over the past couple of years - mostly involving cancer and some with Hepatitis and other conditions. From what I have seen so far in cancer, it appears to be more effective in slowing tumor growth than in actually getting rid of cancer completely - but perhaps that is because many of the reports I have seen come from my Yahoo health group Oleandersoup where people have turned to oleander after LDN failed to rid them of cancer.
Although it is a drug, it is one of a very, very few drugs I do not feel terribly uncomfortable with and the low dose normally results in no more than minor side effects. If I were somehow unable to obtain or take oleander, which has helped people when LDN failed and is a superior cancer fighter and immune booster imho, I might consider it as one of my supplemental choices if I had cancer or hepatitis.
As it is, I would say take it but perhaps also take more than just LDN to have the best chances.
