[Menene Huperzine A]

Huperzia wani nau'i ne na gansakuka da ke tsiro a kasar Sin. Yana da alaƙa da mosses kulob ( dangin Lycopodiaceae ) kuma an san shi ga wasu masana kimiyya kamar Lycopodium serratum . An yi amfani da gansakuka da aka shirya gaba ɗaya ta al'ada. Shirye-shiryen ganye na zamani suna amfani ne kawai da keɓaɓɓen alkaloid da aka sani da huperzine A. Huperzine A shine alkaloid da aka samu a cikin huperzia wanda aka ruwaito don hana rushewar acetylcholine, wani muhimmin abu da tsarin juyayi ke buƙata don watsa bayanai daga tantanin halitta zuwa tantanin halitta. Binciken dabbobi ya nuna cewa ikon huperzine A na adana acetylcholine na iya zama mafi girma fiye da na wasu magungunan magani. Asarar aikin acetylcholine shine siffa ta farko na rikice-rikice da yawa na aikin kwakwalwa, gami da cutar Alzheimer. Hakanan Huperzine A na iya samun tasirin kariya akan nama na kwakwalwa, yana ƙara haɓaka yuwuwar iliminsa don taimakawa rage alamun wasu cututtukan kwakwalwa.
