Benefits of herbs & spices for cognition

An ingredient of the curry spice turmeric called curcumin is a powerful antioxidant and anti-inflammatory apparently helps learning and memory through its action on BDNF. It may also fight against amyloid plaques, and so help fight Alzheimer's.

Two small studies indicate that the herbs sage and lemon balm also help cognition. Both of these seem to increase the activity of acetylcholine, and so may be helpful to protect against Alzheimer's.
