Uninzi lwezongezo zezityalo eziqhelekileyo, eziquka iti eluhlaza kunye neginkgo biloba, zinokusebenzisana namachiza achazwe ngugqirha, ngokophononongo olutsha lophando olupapashwe kwiBritish Journal of Clinical Pharmacology. Olu nxibelelwano lunokwenza ukuba ichiza lingasebenzi kwaye linokuba yingozi okanye libulale.
Oogqirha bayazi ukuba imifuno inokuchaphazela iirejimeni zonyango, abaphandi abavela kwiBhunga loPhando lwezoNyango eMzantsi Afrika babhala kwiphepha elitsha. Kodwa ngenxa yokuba abantu ngokwesiqhelo abaxeleli ababoneleli ngezempilo ukuba ngawaphi amayeza athengiswayo kunye nezongezo abazithathayo, bekunzima kwizazinzulu ukugcina umkhondo wokuba leliphi ichiza kunye nendibaniselwano ezongezelelweyo ekufuneka ziphephe.
Uphononongo olutsha luhlalutye iingxelo ze-49 zokuphendulwa kweziyobisi ezimbi kunye nezifundo ezimbini zokujonga. Uninzi lwabantu kuhlalutyo lwalunyangwa ngenxa yesifo senhliziyo, umhlaza, okanye ukutshintshwa kwezintso kwaye bathatha i-warfarin, i-statins, i-chemotherapy drug, okanye i-immunosuppressants. Abanye babenokudakumba, ukuxhalaba, okanye ukuphazamiseka kwemithambo-luvo yaye banyangwa ngamayeza okuthomalalisa uxinezeleko, amayeza okubulala ingqondo, okanye amayeza okuthomalalisa.
Ukususela kwezi ngxelo, abaphandi banqume ukuba ukusebenzisana kweziyobisi zemifuno "kunokwenzeka" kwi-51% yeengxelo kwaye "kunokwenzeka kakhulu" malunga ne-8% yeengxelo. Malunga ne-37% yachazwa njengokunxibelelana kwamachiza e-herbal, kwaye yi-4% kuphela eyabonwa njengekrokrisayo.
Kwimeko enye ingxelo, isigulane esithatha i-statins sakhalaza ngomlenze onzima kunye neentlungu emva kokusela iikomityi ezintathu zeti eluhlaza ngosuku, nto leyo isiphumo esiqhelekileyo. Abaphandi babhala ukuba le mpendulo yayibangelwa yimpembelelo yeti eluhlaza kumanqanaba egazi le-statins, nangona bathi uphando olungakumbi luyafuneka ukulawula ezinye izizathu ezinokwenzeka.
Kwenye ingxelo, isigulana sisweleke emva kokuxhuzula ngelixa sidada, nangona sithatha amayeza aqhelekileyo okunyanga le meko. Nangona kunjalo, i-autopsy yakhe yabonisa ukuba wehlile amanqanaba egazi kula machiza, mhlawumbi ngenxa yezongezelelo zeginkgo biloba awayezithatha rhoqo, ezichaphazela ukuchithwa kwazo.
Ukuthatha izongezelelo zemifuno kuye kwadibaniswa neempawu ezibuhlungu zokudakumba kubantu abathatha i-antidepressants, kunye nokulahlwa kwelungu kubantu abaye banezintso, intliziyo, okanye isibindi, ababhali babhala kwinqaku. Kwizigulana zomhlaza, amayeza echemotherapy abonakaliswe ukuba anxibelelane nezongezelelo zemifuno, kubandakanya i-ginseng, i-echinacea, kunye nejusi ye-chokeberry.
Uhlalutyo lukwabonise ukuba abaguli abathatha i-warfarin, enciphisa igazi, banike ingxelo "yentsebenziswano ebalulekileyo yekliniki." Abaphandi baqikelela ukuba ezi zityalo zinokuphazamisana nemetabolism ye-warfarin, ngaloo ndlela inciphisa amandla ayo e-anticoagulant okanye ibangele ukopha.
Ababhali bathi izifundo ezininzi zelebhu kunye noqwalaselo olusondeleyo kubantu bokwenyani ziyafuneka ukubonelela ngobungqina obunamandla bokusebenzisana phakathi kwemifuno ethile kunye neziyobisi. "Le ndlela iya kwazisa abasemagunyeni olawulo lwamachiza kunye neenkampani zamachiza ukuba zihlaziye ulwazi lwelebhile ngokusekelwe kwidatha ekhoyo ukuphepha iziphumo ezibi," babhala.
Kwakhona ukhumbuza izigulane ukuba kufuneka zihlale zixelela oogqirha babo kunye noosokhemisti malunga nawaphi na amayeza okanye izongezo abazithathayo (kunye neemveliso ezithengiswa njengendalo okanye i-herbal), ngakumbi ukuba banikwe iyeza elitsha.
