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).
