HuperzineA 1%99%

Huperzine A is a substance purified from a plant called Chinese club moss. It is a highly purified drug, unlike herbs that typically contain hundreds of chemical ingredients. As a result, some people regard huperzine A as a drug, and they argue that it stretches the guidelines of the Dietary SupplementHealth and Education Act (DSHEA).Jianhe Biotech Co., Ltd Supplysideshow, Vitafoods, HIE.
Be careful not to confuse huperzine A, which is also called selagine, with similar sounding medications such as selegiline (Eldepryl). Also be careful not to confuse one of the brand names for huperizine A (Cerebra) with the brand names for unrelated prescription drugs such as celecoxib (Celebrex), citalopram (Celexa), and fosphenytoin (Cerebyx).
Huperzine A is used for Alzheimer's disease, memory and learning enhancement, and age-related memory impairment. It is also used for treating a muscle disease called myasthenia gravis, for increasing alertness and energy, and for protecting against agents that damage the nerves such as nerve gases.
Products that combine huperzine A with certain drugs used for treating Alzheimer’s disease are being studied. These “hybrid” products are of interest because they may be effective at lower doses and, therefore, cause fewer side effects. One hybrid, called huprine X, combines huperzine A with the drug donepezil. Another hybrid being studied contains huperzine A and the drug tacrine.
How does it work?
Huperzine A is thought to be beneficial for problems with memory, loss of mental abilities (dementia), and the muscular disorder myasthenia gravis because it causes an increase in the levels of acetylcholine. Acetylcholine is one of the chemicals that our nerves use to communicate in the brain, muscles, and other areas.
