When I had papillary thyroid cancer, I saw a naturopath who specializes in thyroid cancer and he prescribed mistletoe to me (amongst other supplements). The mistletoe was for self-administered subcutaneous injection, not an IV. The initial reaction is temporary redness, subtle swelling and itchiness at the injection site (abdominal fat tissue). This is an indicator that the dose is correct. Once the body gets used to the mistletoe the reaction lessens or dissipates and a higher dose is prescribed. I did it for a while and can't say I felt anything or noticed any changes, but I never had any symptoms from the cancer anyway. I stopped doing the injections after I found a doc at the Mayo clinic who pioneered the use of alcohol ablation to kill the cancer within the nodule, simply by injecting a needle with pure alcohol into it. No surgery, negligible pain, outpatient procedure, I have a well working thyroid intact. I'm afraid I'm not helping to really answer your question well, but that was my experience with mistletoe. Oh, and by the way the naturopath only saw post-surgical cases, but I was the exception, so mistletoe was never presented as a cure (though maybe he thought it could be . . .), but rather as a way to avoid reoccurrence.
