Huperzia ndi mtundu wa moss womwe umamera ku China.Zimagwirizana ndi mosses zamakalabu (banja la Lycopodiaceae) ndipo akatswiri ena amadzimadzi amadziwika kuti Lycopodium serratum.Moss yonse yokonzedwa idagwiritsidwa ntchito mwamwambo.Kukonzekera kwa zitsamba zamakono kumagwiritsa ntchito alkaloid yokhayokha yotchedwa huperzine A. Huperzine A ndi alkaloid yomwe imapezeka mu huperzia yomwe yanenedwa kuti imalepheretsa kuwonongeka kwa acetylcholine, chinthu chofunika kwambiri chomwe chimafunikira dongosolo lamanjenje kuti lipereke chidziwitso kuchokera ku selo kupita ku selo.Kafukufuku wa zinyama wasonyeza kuti mphamvu ya huperzine A yosunga acetylcholine ingakhale yaikulu kuposa ya mankhwala ena olembedwa ndi dokotala.Kutayika kwa ntchito ya acetylcholine ndi gawo loyamba la zovuta zingapo za ubongo, kuphatikizapo matenda a Alzheimer's.Huperzine A itha kukhalanso ndi chitetezo paminyewa yaubongo, ndikuwonjezera kuthekera kwake kothandizira kuchepetsa zizindikiro za zovuta zina zaubongo.
[Ntchito] Yogwiritsidwa ntchito m'mankhwala osagwiritsidwa ntchito masiku onse, huperzine A yapezedwa kuti imakhala ngati cholinesterase inhibitor, mtundu wa mankhwala omwe amagwiritsidwa ntchito poletsa kusweka kwa acetylcholine (mankhwala ofunikira pophunzira ndi kukumbukira).
Osagwiritsidwa ntchito ngati chithandizo cha matenda a Alzheimer's, huperzine A imanenedwanso kuti imathandizira kuphunzira ndi kukumbukira komanso kuteteza ku kuchepa kwa chidziwitso chokhudzana ndi ukalamba.
Kuonjezera apo, huperzine A nthawi zina amagwiritsidwa ntchito kulimbikitsa mphamvu, kuonjezera tcheru, ndi kuthandizira kuchiza myasthenia gravis (matenda a autoimmune omwe amakhudza minofu).
