What it's normally used for
Huperzine A enhances memory, learning, and neuroplasticity. It's been shown to improve age-related memory loss.
Some research suggests that taking Huperzine A for up to eight weeks can improve mental function, memory, and behavior in people with conditions like Alzheimer's disease or dementia. Other research shows that taking huperzine A for four weeks improves the memory of older children and teenagers who have memory problems.
What it does for Lucid Dreaming
Huperzine A is an acetylcholine esterase (AChE) inhibitor which means it's main job is to block the normal breakdown of the neurotransmitter, acetylcholine.
Huperzine A stops the breakdown of acetylcholine by blocking acetylcholinesterase, the substance that breaks down acetylcholine.
It also helps prevent the breakdown of choline, which is one of the brain's key neurotransmitters.
My own results
I have one Huperzine A after I have six hours of sleep and it is easier to remember the dream.
