If you remember Vioxx, Celebrex and a few "well regulated" drugs that have themselves become controversial after extensive research and approval, why would you go get yourself some "herbal" therapy.
Herbal remedies were or are effective only if you are dealing with an expert. It is shocking to realize that some people did not even realize what they were getting in the form of treatment.
It is not to say that Western Medicine is anymore advanced, but because of the regulation and legalities, it is atleast safe to the extent that neither the government nor the companies involved, have presented you with fraudulent information on drugs.
Our current understanding of cancer, its origins and treatments is feeble at its best, so you would be better warned to try the tested path to treatment.
