I-Ginkgo biloba, noma ucingo lwensimbi, isihlahla esidabuka eShayina esiye satshalwa izinkulungwane zeminyaka ukuze sisetshenziswe ngezindlela ezahlukene.
Njengoba kuwukuphela kommeleli wezitshalo zasendulo osindile, ngezinye izikhathi ubizwa ngokuthi insalela ephilayo.
Nakuba amaqabunga nembewu yawo kuvame ukusetshenziswa emithini yendabuko yaseShayina, ucwaningo lwamanje lugxile ezikhishweni ze-ginkgo ezenziwe ngamaqabunga.
Izithako ze-Ginkgo ziye zahlotshaniswa nezimangalo eziningana zezempilo kanye nokusetshenziswa kwazo, eziningi zazo ezigxile ekusebenzeni kobuchopho kanye nokujikeleza kwegazi.
I-Ginkgo biloba igcwele ama-flavonoid nama-terpenoid, amakhemikhali aziwa ngemiphumela yawo enamandla yokulwa nama-antioxidant.
Ama-free radical ayizinhlayiya ezisabela kakhulu emzimbeni ngesikhathi semisebenzi evamile yokugaya ukudla njengokuguqula ukudla kube amandla noma ukuhlanza umzimba.
Nokho, zingalimaza nezicubu ezinempilo futhi zisheshise ukuguga nezifo.
Ucwaningo ngomsebenzi we-ginkgo biloba wokulwa nokuvuvukala luyathembisa kakhulu. Kodwa-ke, akucaci kahle ukuthi isebenza kanjani nokuthi isebenza kahle kangakanani ekwelapheni izimo ezithile.
I-Ginkgo iqukethe ama-antioxidants anamandla alwa nemiphumela elimazayo yama-free radicals futhi kungenzeka ukuthi iyimbangela yezinsolo zayo eziningi zempilo.
Ekuphenduleni kokuvuvukala, izingxenye ezahlukene zesimiso somzimba sokuzivikela ziyavuselelwa ukuze zilwe nabahlaseli bakwamanye amazwe noma zelaphe izindawo ezonakele.
Ezinye izifo ezingamahlalakhona zingabangela ukusabela kokuvuvukala ngisho noma kungekho sifo noma ukulimala. Ngokuhamba kwesikhathi, lokhu kuvuvukala okweqile kungabangela umonakalo ongapheli ezicutshini zomzimba kanye ne-DNA.
Iminyaka eminingi yezifundo zezilwane kanye ne-test-tube ibonise ukuthi i-Ginkgo biloba extract inciphisa izimpawu zokuvuvukala emangqamuzaneni abantu kanye nezilwane ezimweni ezahlukene zezifo.
Nakuba le mininingwane ikhuthaza, kudingeka izifundo zabantu ngaphambi kokuba kutholakale iziphetho eziqondile mayelana nendima ye-ginkgo ekwelapheni lezi zifo eziyinkimbinkimbi.
I-Ginkgo inamandla okunciphisa ukuvuvukala okubangelwa izifo ezahlukahlukene. Lokhu kungaba esinye sezizathu ezenza ibe nohlu olubanzi lwezinhlelo zokusebenza zezempilo.
Emithini yendabuko yaseShayina, imbewu ye-ginkgo isetshenziselwa ukuvula “iziteshi” zamandla ezinhlelweni ezahlukene zezitho zomzimba, okuhlanganisa izinso, isibindi, ubuchopho namaphaphu.
Ikhono likaGinkgo elibonakalayo lokwandisa ukugeleza kwegazi ezingxenyeni ezahlukene zomzimba lingase libe umthombo wezinzuzo eziningi okuthiwa unazo.
Ucwaningo lweziguli zesifo senhliziyo ezathatha i-ginkgo lubonise ukwanda okusheshayo kokugeleza kwegazi ezingxenyeni eziningana zomzimba. Lokhu kuhlotshaniswa nokwanda okungu-12% kwamazinga e-nitric oxide ajikeleza egazini, into ebangela ukwanda kwemithambo yegazi.
Ngokufanayo, olunye ucwaningo lubonise umphumela ofanayo kubantu abadala abathole i-ginkgo extract (8).
Ezinye izifundo zikhomba nemiphumela yokuvikela ye-ginkgo empilweni yenhliziyo, impilo yobuchopho, kanye nokuvimbela isifo sohlangothi. Kunezincazelo eziningana ezingaba khona zalokhu, enye yazo kungaba ukuba khona kwamakhemikhali alwa nokuvuvukala ezitshalweni.
Kudingeka ucwaningo olwengeziwe ukuze kuqondwe ngokugcwele ukuthi i-ginkgo ithinta kanjani ukujikeleza kwegazi kanye nempilo yenhliziyo nobuchopho.
I-Ginkgo biloba ingandisa ukugeleza kwegazi ngokuthuthukisa ukujikeleza kwegazi. Lokhu kungase kusetshenziswe ekwelapheni izinkinga ezihlobene nokujikeleza kwegazi okungekuhle.
I-Ginkgo ihlolwe kaningi ngekhono layo lokunciphisa ukukhathazeka, ukucindezeleka, nezinye izimpawu ezihlobene nesifo i-Alzheimer's, kanye nokwehla kwengqondo okuhambisana nokuguga.
Ezinye izifundo zikhombisile ukuthi ukusetshenziswa kwe-ginkgo kunganciphisa kakhulu izinga lokwehla kwengqondo kubantu abane-dementia, kodwa ezinye izifundo azikwazanga ukuphinda lo mphumela.
Ukubuyekezwa kwezifundo ezingu-21 kukhombisa ukuthi, uma kuhlanganiswa nemithi yendabuko, i-ginkgo extract ingandisa ukusebenza kubantu abanesifo i-Alzheimer's esincane.
Okunye ukubuyekezwa kuhlole izifundo ezine futhi kwathola ukwehla okukhulu kwezimpawu eziningana ezihlobene ne-dementia ngokusetshenziswa kwe-ginkgo amasonto angu-22-24.
Le miphumela emihle ingase ihlobane nendima i-ginkgo engayidlala ekuthuthukiseni ukugeleza kwegazi ebuchosheni, ikakhulukazi njengoba ihlotshaniswa nokuwohloka kwemithambo yegazi.
Sekukonke, kusesekusha kakhulu ukusho noma ukuphikisa indima ye-ginkgo ekwelapheni i-dementia, kodwa ucwaningo lwamuva nje seluqala ukucacisa lesi sihloko.
Akunakwenzeka ukuphetha ngokuthi i-ginkgo yelapha isifo i-Alzheimer kanye nezinye izinhlobo ze-dementia, kodwa ingaba usizo kwezinye izimo. Amathuba ayo okusiza abonakala ekhula uma isetshenziswa nezindlela zokwelapha ezivamile.
Ucwaningo oluncane oluningi lusekela umbono wokuthi izithako ze-ginkgo zingathuthukisa ukusebenza kwengqondo kanye nenhlalakahle.
Imiphumela yezifundo ezinjalo ivuse izimangalo zokuthi i-ginkgo ihlotshaniswa nokukhuliswa kwenkumbulo, ukugxilisa ingqondo, kanye nesikhathi sokunaka.
Kodwa-ke, ukubuyekezwa okukhulu kwezifundo ngalobu budlelwano kuthole ukuthi ukwengezwa kwe-ginkgo akuzange kuholele kunoma yikuphi ukuthuthuka okulinganiselwe enkumbulo, ekusebenzeni kahle, noma ekhonweni lokunaka.
Ucwaningo oluthile lusikisela ukuthi i-ginkgo ingathuthukisa ukusebenza kwengqondo kubantu abaphilile, kodwa ubufakazi buyaphikisana.
Ukuncipha kwezimpawu zokukhathazeka okubonwe ezifundweni eziningana zezilwane kungase kuhlobane nokuqukethwe kwe-ginkgo biloba okune-antioxidant.
Kokunye ukuhlola, abantu abayi-170 abanesifo sokukhathazeka okujwayelekile bathole ama-240 noma ama-480 mg e-ginkgo biloba noma i-placebo. Iqembu elathola umthamo omkhulu we-ginkgo libike ukwehla okungu-45% kwezimpawu zokukhathazeka uma kuqhathaniswa neqembu le-placebo.
Nakuba izithako ze-ginkgo zingase zinciphise ukukhathazeka, kusenesikhathi kakhulu ukuthola noma yiziphi iziphetho eziqinile ocwaningweni olukhona.
Ucwaningo oluthile lusikisela ukuthi i-ginkgo ingasiza ekwelapheni izinkinga zokukhathazeka, yize lokhu kungenzeka kungenxa yokuqukethwe kwayo kwe-antioxidant.
Ukubuyekezwa kwezifundo zezilwane kusikisela ukuthi izithasiselo ze-ginkgo zingasiza ekwelapheni izimpawu zokucindezeleka.
Amagundane athola i-ginkgo ngaphambi kwesimo esicindezelayo esasiseduze ayenesimo sengqondo esicindezelayo esincane kunamagundane angazange athole isithasiselo.
Ucwaningo lubonise ukuthi lo mphumela ubangelwa yizakhiwo zokulwa nokuvuvukala ze-ginkgo, okuthuthukisa ikhono lomzimba lokubhekana namazinga aphezulu e-hormone yokucindezeleka.
Kudingeka ucwaningo olwengeziwe ukuze kuqondwe kangcono ubudlelwano phakathi kwe-ginkgo nokuthi ithinta kanjani ukucindezeleka kubantu.
Izakhiwo ze-ginkgo zokulwa nokuvuvukala ziyenza ibe ikhambi elingase libe khona lokucindezeleka. Kudingeka ucwaningo olwengeziwe.
Izifundo eziningana zihlole ukuhlobana kwe-ginkgo nokubona kanye nempilo yamehlo. Kodwa-ke, imiphumela yokuqala iyakhuthaza.
Ukubuyekezwa okunye kuthole ukuthi iziguli ze-glaucoma ezathatha i-ginkgo zandisa ukugeleza kwegazi emehlweni, kodwa lokhu akuzange kuholele ekuthuthukisweni kokubona.
Okunye ukubuyekezwa kwezifundo ezimbili kuhlole umphumela we-ginkgo extract ekuqhubekeni kokuwohloka kwe-macular okuhlobene nobudala. Abanye ababambiqhaza babike ukuthi umbono uthuthukile, kodwa lokhu bekungabalulekile ngokwezibalo.
Akwaziwa ukuthi i-ginkgo izothuthukisa yini ukubona kulabo abangenawo ukukhubazeka kokubona.
Kudingeka ucwaningo olwengeziwe ukuze kutholakale ukuthi i-ginkgo ingathuthukisa yini ukubona noma inciphise ukuqhubeka kwesifo samehlo esiwohlozayo.
Ucwaningo oluthile lwasekuqaleni lusikisela ukuthi ukufaka i-ginkgo kungandisa ukugeleza kwegazi emehlweni, kodwa hhayi ngempela ukuthuthukisa ukubona. Kudingeka ucwaningo olwengeziwe.
Emithini yendabuko yaseShayina, i-ginkgo iyindlela ethandwa kakhulu yokwelapha ikhanda elibuhlungu kanye nekhanda elibuhlungu.
Ucwaningo oluncane luye lwenziwa ngekhono le-ginkgo lokwelapha ikhanda. Kodwa-ke, kuye ngokuthi imbangela eyinhloko yaleli khanda ingakanani, kungasiza.
Isibonelo, i-ginkgo biloba yaziwa ngokuba nezakhiwo zokulwa nokuvuvukala kanye ne-antioxidant. I-Ginkgo ingaba usizo uma ikhanda lakho elibuhlungu noma i-migraine ibangelwa ukucindezeleka ngokweqile.
