I'm not taking Xango but another mangosteen product from Australia. I have been taking it for 4 days now. I have suffered for 6 years from some virus/parasite/fungs I have tried so many herbs protocols, bicom/ ayurveda etc etc they all helped and with time I'm sure would have cured. I have been depressed and miserable, anxious about my health and my children's. since taking the Mangosteen, I have more energy, my brain fog has cleared a little (remember only 4 days in) and I don't feel so anxious about every one getting cancer and dieing. I don't care who makes money from it, if it works I will keep on taking it. I can tell you there are a lot of nasty viruses/ parasites etc out there (especially australia) that play havoc with your immune system and if mangosteen helps I will continue taking it and give it to my children and husband,to prevent dis-ease. I think the thing that has really impressed me is the mood elevating properties of this drink. I took Goji and nothing happened.
