Kafukufuku wa Dr. Samira Samarakoon wa Institute of Biochemistry, Molecular Biology and Biotechnology ku yunivesite ya Colombo ndi katswiri wodziwika bwino wa zakudya Dr. DBT Wijeratne anapeza kuti kumwa tiyi wobiriwira pamodzi ndi Centella asiatica kuli ndi ubwino wambiri wathanzi. Gotu kola imawonjezera antioxidant, antiviral ndi immune-boosting properties za tiyi wobiriwira.
Gotu kola amatengedwa kuti ndi therere la moyo wautali ndipo ndi mankhwala achikhalidwe cha ku Asia, pamene tiyi wobiriwira ndi chimodzi mwa zakumwa zotchuka kwambiri padziko lonse lapansi. Ubwino wa tiyi wobiriwira umadziwika bwino ndipo umadyedwa kwambiri ndi ambiri chifukwa cha antioxidant katundu, kuchepetsa kunenepa kwambiri, kupewa khansa, kuchepetsa kuthamanga kwa magazi, ndi zina zambiri. Mofananamo, ubwino wa thanzi la kola umadziwika bwino m'zachipatala zakale za India, Japan, China, Indonesia, South Africa, Sri Lanka, ndi South Pacific. Mayesero amakono a labotale amatsimikizira kuti kola ili ndi antioxidant katundu, ndi yabwino kwa chiwindi, imateteza khungu, imapangitsa kuzindikira ndi kukumbukira. Dr. Samarakoon adanena kuti mukamwa chisakanizo cha tiyi wobiriwira ndi kola, munthu akhoza kupeza ubwino wa thanzi la onse awiri.
Iye adanena kuti Coca-Cola sayenera kukhala ndi 20 peresenti ya osakaniza chifukwa chosavomerezeka ngati chakumwa.
Dr. Vieratne adanena kuti maphunziro am'mbuyomu adatsimikizira kuti kudya gotu kola kumakhudza kwambiri thanzi la chiwindi, makamaka m'mitundu yambiri ya khansa ya chiwindi, hepatocellular carcinoma, mafuta a chiwindi ndi matenda a cirrhosis. Kafukufuku waposachedwapa amasonyezanso kuti kola ingathandize kuchepetsa kuthamanga kwa magazi ndi kuchepetsa chiopsezo cha matenda a mtima, monga sitiroko, myocardial infarction, ndi matenda a mtima. Maphunziro a pharmacological asonyeza kuti kola Tingafinye amatha kulamulira ntchito ya chapakati mantha dongosolo ndi kusintha chidziwitso ntchito za ubongo.
Dr. Wijeratne akunena kuti ubwino wathanzi wa tiyi wobiriwira umadziwika bwino padziko lonse lapansi. Pali kafukufuku wasayansi wokhudza thanzi la tiyi wobiriwira kuposa gotu kola. Tiyi wobiriwira ali ndi katekisimu, polyphenols, makamaka epigallocatechin gallate (EGCG). EGCG ndi antioxidant wamphamvu yomwe imatha kupha maselo a khansa popanda kuwononga maselo abwinobwino. Kuphatikizikaku kumathandizanso kutsitsa cholesterol yotsika kachulukidwe ya lipoprotein, kuletsa magazi kuundana, komanso kuchepetsa kuphatikizika kwa mapulateleti. Kuonjezera apo, tiyi wobiriwira wa tiyi wapezeka kuti ndi gwero lodalirika la antioxidants zachilengedwe zomwe zimagwiritsidwa ntchito bwino kuti ziwonjezere antioxidant katundu, akutero Dr. Wijeratne.
Malingana ndi iye, kunenepa kwambiri ndizomwe zimayambitsa matenda ambiri, kuphatikizapo matenda a mtima, kuthamanga kwa magazi, matenda a shuga omwe sadalira insulini, mapapu, osteoarthritis ndi mitundu ina ya khansa. Makatekini a tiyi, makamaka EGCG, ali ndi anti-kunenepa kwambiri komanso odana ndi matenda a shuga. Tiyi wobiriwira amaonedwanso ngati zitsamba zachilengedwe zomwe zimatha kuonjezera ndalama zogwiritsira ntchito mphamvu komanso okosijeni wamafuta kuti achepetse thupi, Dr. Wijeratne adanena, ndikuwonjezera kuti kuphatikiza kwa zitsamba ziwirizi kungapereke ubwino wambiri wathanzi.
