Huperzine A, an alkaloid of Chinese Club Moss, shows remarkable abilities to improve memory, even with those who have Alzheimer’s disease. Its action is to prevent the breakdown of acetyl choline, and acetyl choline is a nerve transmitter. By helping to preserve and build up acetyl choline in the brain, memory improves. This supplement can benefit anyone wanting to improve their memory or even someone preparing for a test or a business presentation. Chinese Club Moss has been used since the start of recorded times in China. It’s traditional use was for fever and inflammation–but then, there was no Alzheimer’s a hundred years ago.
