Huperziawuhlobo lobulembu obumila eShayina.Ihlobene ne-club mosses (umndeni we-Lycopodiaceae) futhi yaziwa kwezinye izazi zezitshalo ngokuthi i-Lycopodium serratum.I-moss yonke elungisiwe yayisetshenziswa ngokwesiko.Amalungiselelo amakhambi esimanje asebenzisa kuphela i-alkaloid engayodwa eyaziwa ngokuthi i-huperzine A. I-Huperzine A iyi-alkaloid etholakala ku-huperzia okuye kwabikwa ukuthi ivimbela ukuwohloka kwe-acetylcholine, into ebalulekile edingwa isimiso sezinzwa ukuze sidlulisele ukwaziswa kusuka kungqamuzana ukuya kungqamuzana.Ucwaningo lwezilwane luphakamise ukuthi i-huperzine A'Ikhono lokulondoloza i-acetylcholine lingase libe likhulu kuneleminye imithi kadokotela.Ukulahlekelwa umsebenzi we-acetylcholine kuyisici esiyinhloko sezinkinga eziningana zokusebenza kobuchopho, kuhlanganise ne-Alzheimer's isifo.I-Huperzine A ingase futhi ibe nomthelela ovikelayo ezicutshini zobuchopho, iqhubeke ikhulise amandla ayo etiyetha okusiza ukwehlisa izimpawu zokuphazamiseka okuthile kobuchopho.

[Umsebenzi] Isetshenziswa kwezinye izindlela zokwelapha, i-huperzine A itholakale isebenza njenge-cholinesterase inhibitor, uhlobo lomuthi olusetshenziselwa ukuvimbela ukuwohloka kwe-acetylcholine (ikhemikhali ebalulekile ekufundeni nasekukhumbuleni).

Ayisetshenziswanga kuphela njengokwelashwa kwe-Alzheimer's, i-huperzine A kuthiwa ithuthukisa ukufunda nenkumbulo futhi ivikele ekunciphiseni kwengqondo okuhlobene neminyaka.

Ngaphezu kwalokho,huperzine Angezinye izikhathi isetshenziselwa ukuqinisa amandla, ukwandisa ukuphaphama, nokusiza ekwelapheni i-myasthenia gravis (isifo esizimele esithinta imisipha).
