Improving memory and removing neurosis:

Man's brain is the central nervous system. It needs much more oxygen and amino acid than any other organs.Moreover,it needs vitamins A.B.C and carotene.Pollen is a kind of natural nerve sedative because of its rich nutrients and is useful for the brain to work.As was said before,pollen has very good effect on heart protection,preventing angiosclerosis and improving circulatory system.

Of course,it is also beneficial to brain protection.Prof.Lin,a tutor of doctorate students,of Northwest Industrial University of China has long researched and considered:the symptoms of a man who suffers from neurosis appear insomnia, memory failure,depression,headache, nervousness,etc.Some patients take drug of nerve sedative,but it has side effects.On the contrary,pollen has no side effect at all.

The brain function has the close relation with the nucleic acids,which can decompose and become nucleotides.It can dilate blood vessels and increase the brain's blood circulation so as to supply the brain with the enough nutrients.

During a man is thinking,his brain is working.So the blood vessels in the brain are expanding and the amount of blood-flow is increasing correspondingly the weight of the brain is increasing.Once a test was done that one man lay on a scale and kept him balance. Then the needle of the scale pointed to the center. At that moment,if the man was thinking about a serious problem,the needle would swing toward the of the man and the scale would incline to the man's head.This showed that blood was flowing to the brain and made the brain weightier,and that is necessary to maintain the blood vessels in brain unobstructed and smooth for blood circulation.
