Huperzine A is a convenient way to support short term and long term memory. Huperzine A may assist in producing brain-boosting effects which may be beneficial for students who regularly study in preparation for an exam. For long term memory, Huperzine A supplements may help reduce the negative effects of aging to memory, learning, and other cognitive functions. Generally, Huperzine supplements can also be used by individuals who just want to maintain mental alertness at work and school. Huperzine A can help with all these effects to the nervous system by promoting healthy levels of the primary neurotransmitter acetylcholine. Some non-clinical studies suggest that Huperzine A benefits normal blood circulation to ensure sufficient blood supply to very important organs. In Chinese folk medicine, natural Huperzine A extract has been used topically to promote natural healing of wounds, bruises, and inflammations.

Huperzine A is an extract derived from Huperzia serrata, a clob moss that belongs to the lycopodium species. Clob mosses like the usual mosses reproduce through their spores. However, they possess unique fluid-conducting tissues. The Chinese were the first to take advantage of Huperzine A benefits as its use has been documented during the reign of the Tang dynasty. This plant alkaloid is also famous for its other names as Qian Ceng Ta and Chien Tseng Ta. Chinese folk medicine used it for normal healing of wounds, bruises, and swelling. In 1980, Chinese scientists began to study the chemistry and pharmacology of Huperzia serrata and Huperzine A. Modern Huperzine A studies revealed that it produce beneficial effects to acetylcholine levels in the brain. It does this by blocking the action of acetylcholinesterase, an enzyme that breaks down acetylcholine. With this mechanism, there is more acetylcholine produced and used by the brain for many important mental functions like thinking, remembering, and learning. By promoting healthy acetylcholine levels, Huperzine A can help benefit all these important brain processes. Alzheimer’s disease and other dementias has been linked to low acetylcholine levels and some prescription medications for these conditions are aimed to increase acetylcholine concentrations. Dementias are characterised by severe memory loss and loss of other important mental functions.
