Huperzia Serrate extract

Huperzine A is a naturally occurring compound extracted from the Huperzia Serrata moss. Huperzine A acts as an Acetylcholinesterase Inhibitor, allowing an increase of the neurotransmitter Acetycholine, with a beneficial effect on memory, attention and neuronal plasticity.

Huperzine A and huperzine B are two of the chemicals that have been separated from Chinese club moss. Huperzine B is also an acetylcholinesterase inhibitor, but because its effects are much weaker than those of huperzine A, most research has focused on huperzine A. Synthetic forms of huperzine A have been made in chemical laboratories and they appear to be as effective as natural huperzine A in studies. Huperzine A has also been combined or "hybridized" with the prescription drug tacrine (Cognex), an acetylcholinesterase inhibitor approved by the U.S. Food and Drug Administration (FDA) for treating Alzheimer’s disease. The resulting "huprine" combination seems to be more effective at limiting acetylcholinesterase activity than either agent alone. Much more study needs to be done on the possible effects of huperzine A, huperzine B, huprine, and other chemicals derived from Chinese club moss.
