Ucwaningo lukaDkt. Samira Samarakoon we-Institute of Biochemistry, Molecular Biology and Biotechnology eNyuvesi yaseColombo kanye nososayensi wezokudla odumile uDkt. DBT Wijeratne luthole ukuthi ukuphuza itiye eliluhlaza kanye neCentella asiatica kunezinzuzo eziningi zezempilo. I-Gotu kola ithuthukisa izakhiwo zetiye eliluhlaza ezilwa ne-antioxidant, ezilwa namagciwane kanye nezokuqinisa amasosha omzimba.
I-Gotu kola ibhekwa njengekhambi elihlala isikhathi eside futhi iyisisekelo semithi yendabuko yase-Asia, kanti itiye eliluhlaza lingenye yeziphuzo zezempilo ezidumile emhlabeni. Izinzuzo zezempilo zetiye eliluhlaza zaziwa kakhulu futhi zisetshenziswa kabanzi ngabaningi ngenxa yezakhiwo zalo zokulwa ne-antioxidant, ukunciphisa ukukhuluphala, ukuvimbela umdlavuza, ukwehlisa umfutho wegazi, nokuningi. Ngokufanayo, izinzuzo zezempilo ze-kola zaziwa kakhulu emikhubeni yezokwelapha yasendulo yaseNdiya, eJapane, eShayina, e-Indonesia, eNingizimu Afrika, eSri Lanka, naseNingizimu Pacific. Ukuhlolwa kwelebhu yesimanje kuqinisekisa ukuthi i-kola inezakhiwo zokulwa ne-antioxidant, ilungele isibindi, ivikela isikhumba, futhi ithuthukisa ukuqonda kanye nenkumbulo. UDkt. Samarakoon uthe uma uphuza ingxube yetiye eliluhlaza kanye ne-cola, umuntu angathola zonke izinzuzo zezempilo zakho kokubili.
Uthe iCoca-Cola akufanele ibe namaphesenti angaphezu kwangu-20 engxube ngenxa yokwamukeleka okuncane njengesiphuzo.
UDkt. Vieratne uthe izifundo zangaphambilini ziqinisekisile ukuthi ukudla i-gotu kola kunomthelela omuhle ekuthuthukiseni impilo yesibindi, ikakhulukazi ezinhlotsheni ezivame kakhulu zomdlavuza wesibindi oyinhloko, i-hepatocellular carcinoma, i-fatty liver kanye ne-cirrhosis. Izifundo zakamuva zibonisa nokuthi i-cola ingasiza ekwehliseni umfutho wegazi futhi inciphise ingozi yesifo senhliziyo, okuhlanganisa nesifo sohlangothi, i-myocardial infarction, kanye nesifo senhliziyo. Izifundo ze-pharmacological zikhombisile ukuthi i-kola extract ingalawula umsebenzi wesimiso sezinzwa esiyinhloko futhi ithuthukise imisebenzi yobuchopho yokuqonda.
UDkt. Wijeratne uveza ukuthi izinzuzo zezempilo zetiye eliluhlaza zaziwa kakhulu emhlabeni wonke. Kukhona ucwaningo lwesayensi oluningi ngezinzuzo zezempilo zetiye eliluhlaza kune-gotu kola. Itiye eliluhlaza licebile ngama-catechin, ama-polyphenols, ikakhulukazi i-epigallocatechin gallate (EGCG). I-EGCG iyi-antioxidant enamandla engabulala amangqamuzana omdlavuza ngaphandle kokulimaza amangqamuzana avamile. Le nhlanganisela iyasebenza futhi ekwehliseni i-cholesterol ye-lipoprotein ephansi, ivimbele amahlule egazi angajwayelekile, futhi inciphise ukuhlangana kwama-platelet. Ngaphezu kwalokho, i-extract yetiye eliluhlaza itholakale ingumthombo othembisayo wama-antioxidants emvelo asetshenziswa ngempumelelo ukuthuthukisa izakhiwo ze-antioxidant, kusho uDkt. Wijeratne.
Ngokusho kwakhe, ukukhuluphala kuyimbangela eyinhloko yezifo eziningi, okuhlanganisa isifo senhliziyo, umfutho wegazi ophakeme, isifo sikashukela esingaxhomekile ku-insulin, ukungasebenzi kahle kwamaphaphu, i-osteoarthritis kanye nezinhlobo ezithile zomdlavuza. Ama-catechin etiye, ikakhulukazi i-EGCG, anemiphumela yokulwa nokukhuluphala kanye neyokulwa nesifo sikashukela. Itiye eliluhlaza libhekwa njengekhambi lemvelo elingakhuphula ukusetshenziswa kwamandla kanye nokushiswa kwamafutha ukuze kwehliswe isisindo, kusho uDkt. Wijeratne, enezela ngokuthi ukuhlanganiswa kwamakhambi amabili kunganikeza izinzuzo eziningi zezempilo.
