it was noted that the use of magnolia extracts reduced the levels of ‘quinolinic acid’ in the brain. This acid is a by-product of certain brain functions and has been associated with psychotic conditions and neurodegenerative processes of brain tissue. Also, there was an additional reduction in free calcium levels in the brain tissue, thereby reducing calcium overload. As a result, the use of Magnolia not only relieves depression and anxiety, but is also a tonic for brain function and health.
