This is an unrehearsed discussion of my experience and knowledge of white pine. I don’t use it frequently as there are other sources that can work fine. The white pine can take your body in a unique direction medicinally though.

The inner bark causes a tightening up feeling in my body, particularly my brain. It seems to improve my thoughts, but I’m not sure if I would actually score any higher on a test or not. It may just cause me to only feel confident in the effect.
