Vitamin B17

I have a patient asking about Vitamin B17. She states the only place she knows about that she can buy it is in the UK. I do not know much about this vitamin and its use for cancer. Please, does any one know of some one that has used this and what cancers does it work best against? I have found very little on this in the US. Most places I find to purchase Vit B17 is on other countries. It is safe? Does it work? Any info you have would be appriciated. Thanks in advance.

to be honest not something I know much about but did a search and found this

Hi

If you search for laetrile/amygdalin (B17) on the web you get a lot of interesting junk as well as the useful stuff posted by Silverdragon102. I did a Medline search on the stuff - there are warnings about cyanide poisoning, this FDA prosecution http://www.fda.gov/fdac/departs/2001/201_irs.html of someone selling the stuff and this article which may be illuminating http://caonline.amcancersoc.org/cgi/reprint/41/3/187
