Uphononongo olwenziwa nguDkt. Samira Samarakoon weZiko le-Biochemistry, i-Molecular Biology kunye ne-Biotechnology kwiYunivesithi yaseColombo kunye nesondlo esaziwayo uDkt DBT Wijeratne wafumanisa ukuba ukusela itiye eluhlaza ngokudibanisa neCentella asiatica kuneenzuzo ezininzi zempilo. I-Gotu kola iphucula i-antioxidant, i-antiviral kunye ne-immune-boosting properties yeti eluhlaza.
IGotu kola ithathwa njengesityalo esihlala ixesha elide kwaye sisisiseko samayeza esintu aseAsia, ngelixa iti eluhlaza sesona siselo sidumileyo sezempilo. Iinzuzo zezempilo zeti eluhlaza ziyaziwa kwaye zisetyenziswa ngokubanzi ngabaninzi ngenxa yeempawu zayo ze-antioxidant, ukunciphisa ukutyeba, ukuthintela umhlaza, ukunciphisa uxinzelelo lwegazi, kunye nokunye. Ngokufanayo, izibonelelo zezempilo ze-kola ziyaziwa kwiindlela zonyango zakudala zaseIndiya, eJapan, eChina, e-Indonesia, eMzantsi Afrika, eSri Lanka naseSouth Pacific. Iimvavanyo zaselabhorethri zanamhlanje ziqinisekisa ukuba i-kola ineempawu ze-antioxidant, ilungile kwisibindi, ikhusela ulusu, kwaye iphucula ukuqonda kunye nenkumbulo. UDkt Samarakoon uthe xa usela umxube weti eluhlaza kunye ne-cola, umntu unokufumana zonke izibonelelo zempilo zombini.
Uthe iCoca-Cola akufuneki iqulathe ngaphezulu kwe 20 pesenti yomxube ngenxa yokungamkeleki kancinci njengesiselo.
UDkt Vieratne uthe izifundo zangaphambili ziqinisekisile ukuba ukutya i-gotu kola kunefuthe elihle ekuphuculeni impilo yesibindi, ngokukodwa kwiindlela eziqhelekileyo zomhlaza wesibindi sokuqala, i-hepatocellular carcinoma, isibindi esinamafutha kunye ne-cirrhosis. Uhlolisiso lwakutshanje lukwabonisa ukuba i<em>cola inokunceda ukunciphisa uxinzelelo lwegazi ize inciphise ingozi yesifo sentliziyo, kuquka i<em>stroke, i<em>myocardial infarction, nesifo sentliziyo. Izifundo ze-Pharmacological zibonise ukuba i-kola extract inokulawula umsebenzi we-nervous system kunye nokuphucula imisebenzi yokuqonda kwengqondo.
UGqr Wijeratne ubonisa ukuba inzuzo yezempilo ye-green tea iyaziwa kwihlabathi jikelele. Kukho uphando lwezenzululwazi malunga neenzuzo zezempilo zeti eluhlaza kune-gotu kola. I-tea ehlaza isityebi kwiikatechin, iipolyphenols, ngakumbi i-epigallocatechin gallate (EGCG). I-EGCG yi-antioxidant enamandla enokubulala iiseli zomhlaza ngaphandle kokonakalisa iiseli eziqhelekileyo. Le khompawundi iyasebenza ekwehliseni i-low-density lipoprotein cholesterol, inqanda amahlwili egazi angaqhelekanga, kunye nokunciphisa ukudityaniswa kweeplatelet. Ukongezelela, i-extract tea eluhlaza ifunyenwe njengomthombo othembisayo we-antioxidants yendalo esetyenziswa ngokufanelekileyo ukunyusa iipropati ze-antioxidant, uthi uDkt Wijeratne.
Ngokutsho kwakhe, ukutyeba ngoyena nobangela wezifo ezininzi, kubandakanywa nesifo sentliziyo, uxinzelelo lwegazi oluphezulu, isifo seswekile esingaxhomekekanga kwi-insulin, ukungasebenzi kakuhle kwemiphunga, i-osteoarthritis kunye neentlobo ezithile zomhlaza. I-catechins yeti, ngakumbi i-EGCG, ine-anti-obesity kunye ne-anti-diabetic effects. I-tea eluhlaza nayo ijongwa njengemifuno yendalo enokunyusa inkcitho yamandla kunye ne-oxidation ye-fat oxidation yokulahlekelwa kwesisindo, uDkt Wijeratne uthe, wongezelela ukuba ukudibanisa kwezityalo ezimbini kunokubonelela ngeenzuzo ezininzi zempilo.
