my father had an arthritis for about 5 years. but now he's doing fine. he's been drinking this dietary supplement we bought from a distributor. it contains lots of fruit extracts like noni, goji, mangosteen, pomegranate, billberry, acai, green tea, grape seed and other well known berries. it also helped my father gained his normal blood pressure. he now can work properly. hope this sharing can help you too.
