Scientists at Yale University have developed the first practical method to create a compound called huperzine A (see structure below) in the lab. Huperzine A is a naturally occurring sesquiterpene alkaloid compound found in the plant firmoss Huperzia serrata. Huperzine A is also an Acetylcholinesterase inhibitor, which has a mechanism of action similar to donepezil, rivastigmine, and galantamine. In the US, Huperzine A is sold as a dietary supplement for memory support. The botanical has been used in China for centuries for the treatment of swelling, fever and blood disorders. Clinical trials in China have shown it to be effective in the treatment of Alzheimer's disease and enhancing memory in students.
