I-Ginkgo biloba, noma i-iron wire, isihlahla esidabuka e-China esilinywe izinkulungwane zeminyaka ukusetshenziswa okuhlukahlukene.
Njengoba kuwukuphela kommeleli osekhona wezitshalo zasendulo, ngezinye izikhathi kubizwa ngokuthi imfucumfucu ephilayo.
Nakuba amaqabunga nembewu yawo kuvame ukusetshenziswa emithini yendabuko yamaShayina, ucwaningo lwamanje lugxile ekukhishweni kwe-ginkgo enziwe emaqabunga.
Izithako ze-Ginkgo zihlotshaniswe nezimangalo eziningi zezempilo kanye nokusetshenziswa, eziningi zazo ezigxile ekusebenzeni kobuchopho nokujikeleza.
I-Ginkgo biloba iphezulu kuma-flavonoids nama-terpenoids, izinhlanganisela ezaziwa ngemiphumela yazo enamandla yokulwa ne-antioxidant.
Ama-radicals wamahhala ayizinhlayiya ezisebenza kakhulu ezikhiqizwa emzimbeni ngesikhathi sokusebenza okujwayelekile kwe-metabolic njengokuguqula ukudla kube amandla noma ukukhipha ubuthi.
Nokho, zingalimaza nezicubu ezinempilo futhi zisheshise ukuguga nezifo.
Ucwaningo ngomsebenzi we-antioxidant we-ginkgo biloba luthembisa kakhulu. Kodwa-ke, akucaci kahle ukuthi isebenza kanjani nokuthi isebenza kahle kangakanani ekwelapheni izimo ezithile.
I-Ginkgo iqukethe ama-antioxidant anamandla alwa nemiphumela elimazayo yama-radicals wamahhala futhi kungaba yimbangela yezimangalo zayo eziningi zezempilo.
Ekuphenduleni kokuvuvukala, izingxenye ezihlukahlukene zesimiso sokuzivikela komzimba zisebenza ukulwa nabahlaseli bangaphandle noma ukuphulukisa izindawo ezilimele.
Ezinye izifo ezingapheli zingabangela impendulo yokuvuvukala ngisho nalapho kungabikho isifo noma ukulimala. Ngokuhamba kwesikhathi, lokhu kuvuvukala okweqile kungabangela ukulimala okungapheli ezicutshini zomzimba kanye ne-DNA.
Iminyaka yocwaningo lwezilwane kanye ne-test-tube lubonise ukuthi i-Ginkgo biloba ekhishwayo inciphisa izimpawu ezivuthayo kumangqamuzana abantu nezilwane ezimweni ezihlukahlukene zezifo.
Nakuba le datha ikhuthaza, ucwaningo lwabantu luyadingeka ngaphambi kokuthi kuthathwe iziphetho eziqondile mayelana nendima ye-ginkgo ekwelapheni lezi zifo eziyinkimbinkimbi.
I-Ginkgo inamandla okunciphisa ukuvuvukala okubangelwa izifo ezihlukahlukene. Lokhu kungase kube esinye sezizathu zokuthi kungani inezinhlelo eziningi kangaka zezempilo.
Emithi yendabuko yamaShayina, imbewu ye-ginkgo isetshenziselwa ukuvula "iziteshi" zamandla ezinhlelweni ezihlukahlukene zezitho, kuhlanganise nezinso, isibindi, ubuchopho namaphaphu.
Ikhono elibonakalayo le-Ginkgo lokwandisa ukugeleza kwegazi ezingxenyeni ezihlukahlukene zomzimba kungase kube umthombo wezinzuzo eziningi ezihlosiwe.
Ucwaningo lweziguli zesifo senhliziyo ezithathe i-ginkgo lubonise ukwanda okusheshayo kokugeleza kwegazi ezingxenyeni eziningana zomzimba. Lokhu kuhlotshaniswa nokunyuka kwe-12% kumazinga okujikeleza we-nitric oxide, inhlanganisela ebhekele ukunwetshwa kwemithambo yegazi.
Ngokufanayo, olunye ucwaningo lubonise umphumela ofanayo kubantu asebekhulile abathola i-ginkgo extract (8).
Ezinye izifundo nazo zikhomba emiphumeleni yokuvikela ye-ginkgo empilweni yenhliziyo, impilo yobuchopho, nokuvimbela isifo sohlangothi. Kunezincazelo eziningana ezingase zibe khona zalokhu, enye yazo kungaba ubukhona bezakhi ezilwa nokuvuvukala ezitshalweni.
Ucwaningo olwengeziwe luyadingeka ukuze uqonde ngokugcwele ukuthi i-ginkgo ikuthinta kanjani ukujikeleza nempilo yenhliziyo nempilo yobuchopho.
I-Ginkgo biloba ingakhuphula ukugeleza kwegazi ngokukhuthaza i-vasodilation. Lokhu kungase kusebenze ekwelapheni ukuphazamiseka okuhambisana nokungahambi kahle kwegazi.
I-Ginkgo ihlolwe ngokuphindaphindiwe ukuze ikwazi ukunciphisa ukukhathazeka, ukucindezeleka, nezinye izimpawu ezihlobene nesifo i-Alzheimer's, kanye nokuncipha kwengqondo okuhambisana nokuguga.
Olunye ucwaningo luye lwabonisa ukuthi ukusetshenziswa kwe-ginkgo kunganciphisa kakhulu izinga lokuncipha kwengqondo kubantu abanokuwohloka komqondo, kodwa ezinye izifundo azikwazanga ukuphindaphinda lo mphumela.
Ukubuyekezwa kwezifundo ezingu-21 kubonisa ukuthi, uma kuhlanganiswe nemithi yendabuko, ukukhishwa kwe-ginkgo kungakhuphula ukusebenza kwabantu abanesifo se-Alzheimer esithambile.
Okunye ukubuyekezwa kwahlola izifundo ezine futhi kwathola ukuncipha okuphawulekayo kwenani lezimpawu ezihlobene nokuwohloka komqondo ngokusetshenziswa kwe-ginkgo amasonto angu-22-24.
Le miphumela emihle ingase ihlobane nendima engase idlalwe i-ginkgo ekuthuthukiseni ukugeleza kwegazi ukuya ebuchosheni, ikakhulukazi njengoba iye yaxhunyaniswa nokuwohloka komqondo kwemithambo.
Sekukonke, kusesekuseni kakhulu ukuthi sisho ngokuqondile noma siphikise indima ka-ginkgo ekwelapheni ukuwohloka komqondo, kodwa ucwaningo lwakamuva seluqala ukucacisa lesi sihloko.
Ngeke kuphethwe ngokuthi i-ginkgo yelapha isifo i-Alzheimer kanye nezinye izinhlobo zokuwohloka komqondo, kodwa ingase ibe usizo kwezinye izimo. Amathuba ayo okusiza abonakala ekhula uma esetshenziswa nemithi evamile.
Inani elincane lezifundo ezincane lisekela umbono wokuthi izithasiselo ze-ginkgo zingathuthukisa ukusebenza kwengqondo nokuphila kahle.
Imiphumela yocwaningo olunjalo ibangele izinsolo zokuthi i-ginkgo ihlotshaniswa nenkumbulo ethuthukisiwe, ukugxilisa ingqondo, nesikhathi sokunaka.
Kodwa-ke, ukubuyekezwa okukhulu kwezifundo kulobu buhlobo kwathola ukuthi ukwesekwa kwe-ginkgo akuzange kubangele noma yikuphi ukuthuthukiswa okulinganiselwe kumemori, umsebenzi ophezulu, noma ikhono lokunaka.
Olunye ucwaningo lubonisa ukuthi i-ginkgo ingase ithuthukise ukusebenza kwengqondo kubantu abanempilo, kodwa ubufakazi buyangqubuzana.
Ukuncipha kwezimpawu zokukhathazeka ezibonwa ezifundweni eziningana zezilwane kungase kuhlobane nokuqukethwe kwe-antioxidant ku-ginkgo biloba.
Kolunye ucwaningo, abantu abangu-170 abane-generalized disorder disorder bathola u-240 noma 480 mg we-ginkgo biloba noma i-placebo. Iqembu elithole umthamo omkhulu we-ginkgo libike ukwehla okungama-45% kuzimpawu zokukhathazeka uma kuqhathaniswa neqembu le-placebo.
Nakuba izithako ze-ginkgo zinganciphisa ukukhathazeka, kusesekuseni kakhulu ukuthola iziphetho eziqinile ocwaningweni olukhona.
Olunye ucwaningo lubonisa ukuthi i-ginkgo ingasiza ekwelapheni ukuphazamiseka kokukhathazeka, nakuba lokhu kungase kube ngenxa yokuqukethwe kwayo kwe-antioxidant.
Ukubuyekezwa kocwaningo lwezilwane kuphakamisa ukuthi izithako ze-ginkgo zingasiza ekwelapheni izimpawu zokucindezeleka.
Amagundane athola i-ginkgo ngaphambi kwesimo esicindezelayo esiseduze ayenesimo sokucindezeleka esincane kunamagundane angazange athole isengezo.
Ucwaningo luye lwabonisa ukuthi lo mphumela ubangelwa izakhiwo ezilwa nokuvuvukala ze-ginkgo, ezithuthukisa ikhono lomzimba lokubhekana namazinga aphezulu e-hormone yokucindezeleka.
Ucwaningo olwengeziwe luyadingeka ukuze uqonde kangcono ubudlelwano phakathi kwe-ginkgo nokuthi ithinta kanjani ukucindezeleka kubantu.
Izakhiwo zokulwa nokuvuvukala ze-ginkgo ziyenza ibe ikhambi elinamandla lokudangala. Kudingeka ucwaningo olwengeziwe.
Ucwaningo oluningi luye lwahlola ukuhlotshaniswa kwe-ginkgo nombono nempilo yamehlo. Nokho, imiphumela yokuqala iyakhuthaza.
Okunye ukubuyekezwa kwathola ukuthi iziguli ze-glaucoma ezathatha i-ginkgo zandisa ukugeleza kwegazi emehlweni, kodwa lokhu akuzange kuholele ekuboneni ngcono.
Okunye ukubuyekezwa kwezifundo ezimbili kuhlole umphumela wokukhishwa kwe-ginkgo ekuqhubekeleni phambili kokuwohloka kwe-macular okuhlobene neminyaka. Abanye ababambiqhaza babike umbono othuthukisiwe, kodwa sekukonke lokhu bekungabalulekile ngokwezibalo.
Akwaziwa ukuthi i-ginkgo izothuthukisa yini ukubona kulabo abangenakho kakade ukukhubazeka kokubona.
Kudingeka ucwaningo olwengeziwe ukuze kutholakale ukuthi i-ginkgo ingakwazi yini ukuthuthukisa ukubona noma ibambezele ukuqhubeka kwesifo samehlo esiwohlokayo.
Olunye ucwaningo lwangaphambili lusikisela ukuthi ukwengeza i-ginkgo kungase kwandise ukugeleza kwegazi emehlweni, kodwa hhayi ngempela ukuthuthukisa umbono. Kudingeka ucwaningo olwengeziwe.
Emithini yendabuko yamaShayina, i-ginkgo iyikhambi elidume kakhulu lekhanda elibuhlungu kanye nemigraines.
Ucwaningo oluncane olwenziwe ngekhono le-ginkgo lokwelapha ubuhlungu bekhanda. Nokho, kuye ngembangela eyinhloko yekhanda elibuhlungu, kungasiza.
Isibonelo, i-ginkgo biloba yaziwa ngokuthi inezindawo zokulwa nokuvuvukala kanye ne-antioxidant. I-Ginkgo ingase ibe usizo uma ikhanda lakho noma i-migraine ibangelwa ukucindezeleka ngokweqile.
