Chemists create Alzheimer's-fighting extract in lab
Chemists at Yale University are unveiling what they call the first practical method to create the compound huperzine A, which is a naturally occurring extract of Chinese club moss.
The enzyme inhibitor has been used widely in China and now beyond to treat memory loss in disorders such as Alzheimer's disease, and some research indicates it might help fight the effects of chemical warfare agents in primates.
