Alternative medicines

Hi guys,
I was wondering if any of you had taken any alternative medicines with ahving diabetes. Obviously the main point we always must remember is that we must continue to take our Insulin, tablets etc
What I was meaning was I was thinking about taking something like Gingko Bilbo (I think thats how you promounce it) to help boost my circulation or Bilberry fruit which I am told is good for eyesight. Was just wondering if any of you guys had tried these alternatives medicines or other ones and if you had noticed any effect on your diabetes good or bad?

Thanks guys
