Pine Bark Extract pills: Helped with ADHD/ADD?

I was diagnosed with ADD/ADHD a bit ago but I wasn't able to afford the prescription since I wasn't on insurance anymore and finally started looking recently around on the internet for things I could take instead of the name brand stuff. I researched and came across several studies that Pine Bark helped children with ADHD/ADD tendencies.. concentrate more and other stuff.

Two friends on another site I'm on both told me that they took it as well and it helped their symptoms and after 1 month, the pills really kicked in and were able to stabilize it by taking 1 pill everyday, 1-2 every other day to 1 pill a week.

Has anyone else taken it by any chance? And, you know, saw improvements of your ADD/ADHD? Or.. didn't see improvements? Or perhaps felt awful when you took them if you did take them?
