Isithako esidumile sesiphuzo, guarana ( Paullinia cupana ) yisitshalo esivela enyakatho yeBrazil nakwezinye izindawo zase-Amazon. Isithelo sinezilimo ezicebile ze-caffeine eziphindwe kathathu inani le-caffeine njengebhontshisi yekhofi. Imbewu nayo icebile ama-tannins kanye ne-theophylline ne-theobromine.
Okwenza Abantu basebenzise i-Guarana
Wathi ukukhulisa ukuphazamiseka kwengqondo, ukulwa nokukhathala, nokwandisa ukuqina nokusebenza ngokomzimba, i-guarana ivame ukutholakala kuma-sodas neziphuzo zamandla.
Ukunamathisela imbewu, isiraphu noma ukukhishwa kusetshenziselwa ukunambitheka lezi ziphuzo kanye nokunikeza umthombo we-caffeine. EBrazil, iziphuzo ze-guarana futhi zibhekwa njengempilo "ye-tonic" futhi zithandwa kakhulu njenge-sodas yendabuko.
Abagqugquzeli bathi futhi u-guarana angasiza ekunciphiseni ukudla futhi akhuthaze ukulahleka kwesisindo.
Izinzuzo
I-Guarana isetshenziswa ngokuyinhloko njengento evuselela ngenxa yokuqukethwe kwayo ephezulu ye-caffeine.
Isifundo sezilwane sihlolisise umphumela wezinsuku ezingu-14 kwe-supplementation ye-guarana ekusetshenzisweni kwe-fat emagatsheni ahlala phansi futhi aqeqeshiwe futhi wathola ukuthi umphumela we-fatana wokushisa owenziwe ngamafutha ungenxa yokuqukethwe kwe-caffeine. Ama-dessana e-decaffeinated guarana awazange abe nomthelela ekugulweni kwe-lipid metabolism.
I- Journal of Psychopharmacology isifundo sathola ukuthi i-guarana ithuthukise inkumbulo, imizwelo, nokuqaphelisa okuphansi (37.5 mg, 75 mg) naphezulu (150 mg, 300 mg). Kodwa-ke, esinye isifundo sasihlola ukusetshenziswa kwesikhathi eside kwe guarana, i-caffeine, noma i-placebo ekuqondeni abantu abadala abadala abangu-45.
Kwakungekho nemiphumela ebalulekile ye-guarana ekuqondeni.
Imiphumela Ezingenakwenzeka
I-Guarana iqukethe inani elikhulu le-caffeine, elingase lingaboniswa ilebula lomkhiqizo. Uma uzwela nge-caffeine noma i-xanthines noma unenkinga yenhliziyo, ukucindezeleka kwegazi, isifo sezinso , isifo se-thyroid esingasebenzi ngokweqile, ukukhathazeka kokukhathazeka, ukuleleka, noma ukuhlushwa, kufanele ukhulume nomhlinzeki wakho wezempilo ngaphambi kokuthatha i-guarana.
Ukuphakama okuphezulu kwe-caffeine (noma ukuhlanganisa i-guarana nezinye izikhuthazo ezifana ne-yerba mate, izinsiza zokudla, noma izithako ezithuthukisa ukusebenza) kungaholela ekugqibeleni, ama-arrhythmias, ukucindezeleka kwegazi, ukugubha, nezinye izimo ezimbi.
Njengoba odokotela abaningi batusa ukunciphisa i-caffeine ngesikhathi sokukhulelwa nokuncelisa, i-guarana kufanele igwenywe ngoba okuqukethwe kwe-caffeine kuhluke komkhiqizo kuya komkhiqizo futhi akunakwenzeka ukuba abathengi baqikelele ngokunembile ukuthi bangakanani ama-caffeine abawadlayo ngokusebenzisa i-guarana.
I-Guarana akufanele ithathwe nganoma yimiphi imikhiqizo equkethe i- ephedra . Imiphumela emibi kakhulu ebikwe ngale nhlanganisela. Kungase kwandise ingozi yokushaywa isifo, isisu, isifo se-myocardial infarction, nokufa okungazelelwe futhi kuhlotshaniswa nokwanda kwenhliziyo, ukucindezelwa kwegazi, kanye nezinguquko ezinobungozi ezingeni likaglucose namazinga e-potassium. I-Guarana akufanele ihlanganiswe nophuzo noma i-MAO-inhibitors.
I-Guarana itholwe ukunciphisa iplatelet aggregation kanye ne-thromboxane synthesis, ngakho kungandisa ukwanda kokuphuma uma kuthathwe i-aspirin, i-anticoagulants njenge-warfarin (i-Coumadin®), ne-platelet inhibitors njenge-ticlopidine (i-Ticlid®), i-clopidogrel (i-Plavix®) .
Qinisekisa ukuthi ufunde mayelana nokusebenzisa izithako ngokuphepha .
I-Takeaway
I-caffeine-based stimulant, guarana inomlando omude wokusetshenziswa eBrazil njengesithako ekuphuzeni neziphuzo ezihlanganisiwe. Nakuba kungase kubonakale kuyindlela ekhangayo yokukhulisa amandla akho, inkinga nge-guarana yilokho imikhiqizo ingase ingabonisi ngokunembile okuqukethwe kwe-caffeine, eholele abanye abantu ngokungazi ukuthi badle amazinga aphezulu e-caffeine. Futhi, ezinye izithako zingase zixubane nezinye izikhuthazo, okwandisa amathuba okuba nemiphumela emibi.
Uma usacabangela ukuzama i-guarana, khuluma nomhlinzeki wakho wezempilo mayelana nokuthi kufanelekile yini.
