Ucwaningo olwenziwa uDkt. Samira Samarakoon we-Institute of Biochemistry, Molecular Biology and Biotechnology eNyuvesi yaseColombo kanye nesazi sezokudla esidumile uDkt. DBT Wijeratne uthole ukuthi ukuphuza itiye eliluhlaza ngokuhambisana neCentella asiatica kunezinzuzo eziningi zezempilo. I-Gotu kola ithuthukisa i-antioxidant, i-antiviral kanye ne-immune-boosting izakhiwo zetiye eliluhlaza.
I-Gotu kola ibhekwa njengekhambi lesikhathi eside futhi iyisisekelo semithi yendabuko yase-Asia, kuyilapho itiye eliluhlaza lingesinye seziphuzo zezempilo ezithandwa kakhulu emhlabeni. Izinzuzo zezempilo zetiye eliluhlaza zaziwa futhi zisetshenziswa kabanzi ngabaningi ngenxa yezakhiwo zalo ezilwa nokuvuvukala, ukunciphisa ukukhuluphala, ukuvimbela umdlavuza, ukwehlisa umfutho wegazi, nokunye. Ngokufanayo, izinzuzo zezempilo ze-kola zaziwa kakhulu emikhubeni yezokwelapha yasendulo yaseNdiya, eJapane, eChina, e-Indonesia, eNingizimu Afrika, eSri Lanka naseNingizimu Pacific. Ukuhlolwa kwaselabhorethri yesimanje kuqinisekisa ukuthi i-kola inezindawo zokulwa ne-antioxidant, ilungele isibindi, ivikela isikhumba, futhi ithuthukisa ukuqonda nenkumbulo. UDkt. Samarakoon uthe uma uphuza ingxube yetiye eliluhlaza ne-cola, umuntu angathola zonke izinzuzo zezempilo zakho kokubili.
Uthe iCoca-Cola akufanele iqukathe amaphesenti angaphezu kuka-20 engxube ngenxa yokungamukeleki kangako njengesiphuzo.
UDkt Vieratne uthe izifundo zangaphambilini ziqinisekisile ukuthi ukudla i-gotu kola kunomphumela omuhle ekuthuthukiseni impilo yesibindi, ikakhulukazi ezinhlotsheni ezivame kakhulu zomdlavuza wesibindi oyinhloko, i-hepatocellular carcinoma, isibindi esinamafutha kanye ne-cirrhosis. Ucwaningo lwamuva lubonisa nokuthi i-cola ingasiza ekwehliseni umfutho wegazi futhi inciphise amathuba okuba nesifo senhliziyo nemithambo yegazi, kuhlanganise unhlangothi, i-myocardial infarction, nesifo senhliziyo. Ucwaningo lwe-Pharmacological lubonise ukuthi i-kola extract ingalawula umsebenzi wesistimu yezinzwa ephakathi futhi ithuthukise imisebenzi yokuqonda kwengqondo.
UDkt Wijeratne uveza ukuthi izinzuzo zezempilo zetiye eliluhlaza zaziwa emhlabeni wonke. Kunocwaningo oluningi lwesayensi ngezinzuzo zezempilo zetiye eliluhlaza kune-gotu kola. Itiye elihlaza linothile ngamacatechin, ama-polyphenols, ikakhulukazi i-epigallocatechin gallate (EGCG). I-EGCG iyi-antioxidant enamandla engabulala amangqamuzana omdlavuza ngaphandle kokulimaza amaseli avamile. Le nhlanganisela iyasebenza futhi ekwehliseni i-low-density lipoprotein cholesterol, ivimbela amahlule egazi angavamile, futhi inciphise ukuhlangana kweplatelet. Ngaphezu kwalokho, i-green tea extract itholakale iwumthombo othembisayo wama-antioxidants wemvelo asetshenziselwa ngokuphumelelayo ukuthuthukisa izakhiwo ze-antioxidant, kusho uDkt Wijeratne.
Ngokusho kwakhe ukukhuluphala yikona okuyimbangela yezifo eziningi okubalwa kuzo isifo senhliziyo, umfutho wegazi ophakeme, isifo sikashukela esinganciki nge-insulin, ukungasebenzi kahle kwamaphaphu, i-osteoarthritis nezinye izinhlobo ezithile zomdlavuza. I-catechin yetiye, ikakhulukazi i-EGCG, inemiphumela yokulwa nokukhuluphala kanye ne-anti-diabetes. Itiye elihlaza libuye libhekwe njengekhambi lemvelo elingakhuphula ukusetshenziswa kwamandla kanye ne-oxidation yamafutha ekunciphiseni isisindo, kusho uDkt Wijeratne, enezela ukuthi ukuhlanganiswa kwamakhambi amabili kunganikeza izinzuzo eziningi zezempilo.
