Huperzialuhlobo lobulembu obukhula eTshayina.Inxulumene nobulembu beeklabhu (usapho lweLycopodiaceae) kwaye yaziwa kwezinye iingcali ngezityalo njengeLycopodium serratum.I-moss yonke elungisiweyo yayisetyenziswe ngokwesiko.Amalungiselelo amayeza anamhlanje asebenzisa kuphela i-alkaloid ekwanti eyaziwa ngokuba yi-huperzine A. I-Huperzine A yi-alkaloid efumaneka kwi-huperzia eye yaxelwa ukunqanda ukuchithwa kwe-acetylcholine, into ebalulekileyo efunekayo yinkqubo ye-nervous yokuhambisa ulwazi kwiseli ukuya kwiseli.Uphando lwezilwanyana lucebise ukuba i-huperzine A'Ukukwazi ukugcina i-acetylcholine kunokuba nkulu kunokwamanye amayeza kagqirha.Ukulahleka komsebenzi we-acetylcholine luphawu oluphambili lweengxaki ezininzi zomsebenzi wobuchopho, kubandakanya i-Alzheimer'isifo .I-Huperzine A inokuba nefuthe elikhuselayo kwizicubu zobuchopho, inyuse ngakumbi amandla ayo okucinga ukunceda ukunciphisa iimpawu zokuphazamiseka kwengqondo.

[Umsebenzi] Isetyenziswe kunyango olulolunye, i-huperzine A ifunyenwe isebenza njenge-cholinesterase inhibitor, uhlobo lweyeza elisetyenziselwa ukuthintela ukuchithwa kwe-acetylcholine (ikhemikhali ebalulekileyo ekufundeni nasekukhumbuleni).

Ayisetyenziswanga kuphela njengonyango lwe-Alzheimer's isifo, i-huperzine A ikwatsho ukuba iphucule ukufunda kunye nenkumbulo kunye nokukhusela ngokuchasene nokuncipha kwengqondo okunxulumene nobudala.

Ukwengeza,huperzine Angamanye amaxesha isetyenziselwa ukunyusa amandla, ukwandisa ukuphaphama, kunye nokunceda unyango lwe-myasthenia gravis (i-autoimmune disorder echaphazela imisipha).
