Evidence Summary

Huperzine A is a reversible acetylcholinesterase (AChE) inhibitor that increases acetylcholine availability in the brain, and has been clinically approved in China for Alzheimer's disease treatment since 1996 (PMID: 39637486). In a double-blind study of AD patients, 8 weeks of treatment significantly improved cognition and task-switching abilities compared to baseline (PMID: 30839402). Preclinical and pharmacokinetic data show it rapidly penetrates the brain, elevates acetylcholine across multiple brain regions, and may modulate monoamine neurotransmitters (PMID: 41781122). Animal studies also suggest potential for suppressing absence seizures (PMID: 39096485).
