Huperzia Serrata is a type of fir moss that contain the memory-boosting nootropic compound Huperzine A. This acetylcholinesterase inhibitor is known for increasing levels of a neurotransmitter related to memory formation, recall and many of the most basic cognitive functions. The plant itself is also known as Chinese club moss and is native to India and Southeast Asia. The extract of this plant has been used in the traditional medicine of China for centuries. Huperzia Serrata is widely distributed over the counter as both an herbal Alzheimer’s treatment and as a cognitive enhancement supplement. You will find Huperzia Serrata in supplements such as Alpha Brain while most other Huperzine A sources use synthetic versions of this alkaloid.

Huperzine A is a naturally occurring sesquiterpene alkaloid compound found in the firmoss Huperzia serrata and in varying quantities in other Huperzia species, including H. elmeri, H. carinat, and H. aqualupian.

Huperzine A has been found, through multiple studies, to be effective as a medicine for helping people with neurological conditions such as Alzheimer's disease, but the meta-analysis of those studies concluded that they were poor quality and the findings should be interpreted with caution.

Huperzine A is extracted from Huperzia serrata.It is a reversible acetylcholinesterase inhibitor and NMDA receptor antagonist that crosses the blood-brain barrier.The structure of the complex of huperzine A with acetylcholinesterase has been determined by X-ray crystallography (PDB code: 1VOT; see the 3D structure).

For some years, huperzine A has been investigated as a possible treatment for diseases characterized by neurodegeneration – particularly Alzheimer's disease.A 2013 meta-analysis found that huperzine A may be efficacious in improving cognitive function, global clinical status, and activities of daily living for individuals with Alzheimer’s disease. However, due to the poor size and quality of the clinical trials reviewed, huperzine A should not be recommended as a treatment for Alzheimer’s disease until further high quality studies confirm its beneficial effects.

Huperzine A is also marketed as a dietary supplement with claims made for its ability to improve memory and mental function.Huperzine A may also have a possible role in the treatment of myasthenia gravis.
