What are the benefits you can get from gabon as a medicinal plant?

I have tried gabon many times mainly for urinary tract infection. I used it for my father who was having problems with his kidney as well. He had dialysis thrice a week and I used brewed gabon as his water. This time, he is no longer in dialysis but I am also in Another Country now and my father refuses to drink brewed gabon anymore. Too sad.
