First of all I'm sorry to hear about your husband's prostate.  Have you tried Xango's Mangosteen juice (patented formula) which is liquid juice in a bottle and tastes very good.  www.pubmed.gov has many clinical studies on the Xanthones found in Mangosteen juice.  It is a strong anti-imflammatory, anti-tumoral, anti-viral and has whole lot more anti- properties.  Best to do your own due dilligence.  I invite you to see www.NeemaNene.MyManosteen.com for more information on this tropical fruit.  I have a friend who is currently going through prostate cancer and he just started drinking Xango's original Mangosteen's juice. If you would like more information please send me an email at neemajnene@gmail.com
