Searching For Natures Prostate Remedy

A very dear member of our family has been diagnosed with prostate cancer and we are all very concerned since this is such a serious disease.  He has been taken the medication that his doctor prescribed but he is experiencing some pretty severe side effects.  I have always tried to use natural remedies whenever possible so I am doing some research in order to find natures prostate remedy.  I realize that there are many people that have no faith in natural remedies but many people do.  So far I have found out that saw palmetto is widely used to treat prostate cancer and has no known side effects.
