* [[Flavonoids]] from healthy foods such as berries, tea, apples, and red wine cross the delicate blood-brain barrier to protect neurons against neurologic diseases such as Parkinson's.

* [[Picrorhiza]]: the compound known as apocynin was first extracted from the Canadian hemp plant, (apocynum cannabinum) and used to treat heart problems and edema. Now, this little-known plant derivative is being isolated from the Himalayan herb picrorhiza kurroa, and is showing promise for prevention of Parkinson's.
