About Huperzine A:

Huperzine A has been proven superior to drugs licensed for the treatment of Alzheimer's,including the leading anticholine sterase drugs physostigmine and tacrine. Huperzine A improved learning and memory in mice better than tacrine. Unlike physostigmine and tacrine, Huperzine A acts specifically on Ache in the brain rather than Ache found elsewhere in the body i.e., far less is wasted on irrelevat effects. Unlike physostigmine and tacrine, Huperzine A does notappear to bind to receptors in the central nervous system, which can cause adverse side efects. Itseffects last 10 to 12 times longer than physostigmine and tacrine (up to 8 hours).

Huperzine A Function:

1.Huperzine can improve memory, thinking, and behavioral function in people with Alzheimer's disease, multi-infarct dementia, and senile dementia, and increase the level of the neurotransmitter acetylcholine by blocking its breakdown.

 2. It may also protect neurons from cell death caused by toxic levels of glutamate and protect against some of the effects of chemical nerve agents used in warfare,such as soman.

3.It is also the treatment of AD in a randomized controlled trial of its effect on cognitive function.


Huperzine A Application:

1.Treat Alzheimers
2. Treat parkinsonism
3.Relive Chronic headache
4. Cure tristimania
5. Improve sleep quality
6. Memory improvement
