I've just been reading some research by an Australian company, qbiotics, on their drug EBC-46. They are making some remarkable claims, but most of their research has been in vitro, with a small amount of in vivo with induced subcutaneous Squamus Cell Carcinomas in mice, which have shown remarkable results. I don't for one minute think it will be of any use for stage 4 metastatic PCa, but it may work as a first stage treatment for early PCa.
Apart from tabloid hysteria, there doesn't appear to be much information. Anyone know anything about this drug (apart from the fact it comes from the berries of a tree)?
