Anybody using/know anything about mistletoe extract?

I looked into it, following advice from a naturopath, and didn't find the evidence of effectiveness compelling.

I used Iscador for 1 year after diagnosis, then discontinued it for no other reason then my own sense that it was time to stop and it had done it's job.  I went to a naturopath who prescribed it the following day of my dx/ biopsy results.  I felt that even if it didn't do anything, it was emotionally stabilizing for me.  I also feel that since I didn't do chemo or rads, it was just a small part of an overall protocol which included life style changes and supplements.  I can't say if it did anything, but I know this:  I had a very aggressive triple negative tumor with adjoining high grade DCIS.  When I did not do rads (or chemo), my surgeon was extremely upset, and looking back, I think I know why now:  I think he did not dissect the biopsy tracks; he was expecting the rads and chemo to clean that portion up.  I attribute some of my lack of recurrence to the use of Iscador and other interventions, although I have absolutely no proof of this.  If you can afford it, I don't think there is any harm in doing it for at least the minimum recommended time.  I learned that some people stretch the use of each vial by doing one half a vial of the stronger prescription and refridgerating the remaining portion for use the next day.

Please educate yourself as much as possible before you opt out of conventional treatments.  I did not take that road lightly or make any treatment choices based on anecdotal testimony.
