My Dad is in remission from stage 4 stomach cancer to the liver. He currently takes apricot seeds,b17,enzymes and goji juice. I am afraid of it coming back so i am thinking about putting him on Oleander also. Do you think that it would be okay to mix that with what he is taking now? I would hate to take him off the b17 because he is doing so well,but Oleander sounds like a good choice too. I recently ordered him milk thistle tea that he will be starting soon. Any input would be greatly appreciated.
