Isn't it better to offer some specific treatments and therapies to someone in this last stage, rather than a list of things which can be good to someone who is in a much earlier stage? Milk thistle, for example? you have to be kidding. Selenium? He needs something that can work fast. I might suggest you go to cancertutor.com and read the part about stage four cancer. I think it might be cesuim which was said to be able to quickly stop the spread of cancer, but I'm only going by memory. But you may get some ideas at that website. I'm sorry for your and his situation.
