I have 2 different types, capsules and tablets which are supposed to contain the whole plant, but to be honest, I'm not getting much result from either. Initially, I thought I was, but I'm being quite cautious and probably not taking enough. It's true that I feel more alert and drug free, but my movement and muscle control has not improved.
I am thinking of getting the powdered form from Indigo Herbs of Glastonbury. I emailed them to find out what their powders contain and they said they use the bean, the leaf, the bark and root etc.
I'm going to carry on experimenting, until I get some relief though. Good luck to you!
