When I was first diagnosed with cancer and told that there was no cure, I started looking for possible alternate treatments. Escozine, or Blue Scorpion Venom, was the first thing I found. I have not done much research at that point, and ordering escozine was pretty much a knee jerk reaction. I think I paid a little under $3000 for a 3 month supply.
The escozine web site had virtually no information about what Blue Scirpion Venom was exactly, how it worked or what the active ingredients were. Being a scorpion venom, I have to assume that the active ingredient is some kind of neurotoxin. (As an interesting note, TM 601 a synthetic version of chlorotoxin from the deathstalker scorpion is in phase 2 clinical trials to treat glioma and other cancers expressing MMP-2.)
The Blue Scorpion venom contains over 50 chemicals, enzymes and peptides including phozpholipase, hyaluronidase, the venom peptide RjAa12f, which is the active neurotoxin.
Looking at research, scorpion venom may be most effective in treating gliomas, breast cancer and leukemias. (Not very much on colorectal cancer.)
My experience with Escozine was poor. After 2 months of treatment, there was no noticeable impact on my adenocarcenoma. In hind sight it was a waste of money, but still worth a try I think.
Blue scorpion venom is also available in homeopathic preparations such as Vioxx. I would not recommend these, as although cheaper, the dilutions are so low that you are basically paying for pure water.
