What I've read so far (only 3 articles) says it's got promise for Alzheimer's. It's late, so I'll get into it further next week.

I wasn't really looking for skeptical articles at this point, but one came up prominently that got me laughing so hard I thought you might appreciate it. Please don't take this to mean I'm taking any kind of stance on Huperzine A; it's too early, and I have a LOT more reading to do.

It's more about the charlatanism in the claims about some of these mixtures and how they're marketed.
