Huperzine A is a reversible acetylcholinesterase inhibitor and NMDA receptor antagonist that crosses the blood-brain barrier.

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.
