Ubushakashatsi bwakozwe na Dr. Samira Samarakoon wo mu kigo cy’ibinyabuzima, ibinyabuzima bya Molecular na Biotechnologiya muri kaminuza ya Colombo hamwe n’inzobere mu bijyanye n’imirire Dr. DBT Wijeratne bwerekanye ko kunywa icyayi kibisi hamwe na Centella asiatica bifite akamaro kanini ku buzima. Gotu kola yongera antioxydants, antiviral na immunite itera icyayi kibisi.
Gotu kola ifatwa nk'icyatsi kirekire kandi ni kimwe mu bigize imiti gakondo yo muri Aziya, mu gihe icyayi kibisi ari kimwe mu binyobwa by’ubuzima bizwi cyane ku isi. Ibyiza byubuzima bwicyayi kibisi birazwi kandi bikoreshwa cyane na benshi bitewe na antioxydeant, kugabanya umubyibuho ukabije, kwirinda kanseri, kugabanya umuvuduko wamaraso, nibindi byinshi. Mu buryo nk'ubwo, inyungu zubuzima bwa kola zizwi cyane mubikorwa byubuvuzi bya kera byu Buhinde, Ubuyapani, Ubushinwa, Indoneziya, Afurika yepfo, Sri Lanka, na pasifika yepfo. Ibizamini bya laboratoire bigezweho byemeza ko kola ifite antioxydeant, ni nziza ku mwijima, ikingira uruhu, kandi igateza imbere kumenya no kwibuka. Dr. Samarakoon yavuze ko iyo unywa imvange y'icyayi kibisi na cola, umuntu ashobora kubona inyungu zose z'ubuzima zombi.
Yavuze ko Coca-Cola itagomba kubamo ibice birenga 20 ku ijana bivanze kubera kutemerwa nk'ikinyobwa.
Dr. Vieratne yavuze ko ubushakashatsi bwibanze bwemeje ko kurya gotu kola bigira ingaruka nziza mu kuzamura ubuzima bw’umwijima, cyane cyane mu buryo bukunze kugaragara bwa kanseri y’umwijima y’ibanze, kanseri y’umwijima, umwijima w’amavuta na cirrhose.

Ubushakashatsi bwa farumasi bwerekanye ko kola ikuramo ishobora kugenzura imikorere yimitsi yo hagati no kunoza imikorere yubwonko.
Muganga Wijeratne yerekana ko ibyiza byubuzima bwicyayi kibisi bizwi kwisi yose. Hariho ubushakashatsi bwa siyanse kubyiza byubuzima bwicyayi kibisi kuruta gotu kola. Icyayi kibisi gikungahaye kuri catechine, polifenole, cyane cyane epigallocatechin gallate (EGCG). EGCG ni antioxydants ikomeye ishobora kwica kanseri itangiza selile zisanzwe. Uru ruganda kandi rugira akamaro mukugabanya cholesterol ya lipoprotein nkeya, ikabuza gutembera kw'amaraso adasanzwe, no kugabanya gukusanya platine. Dr. Wijeratne avuga ko kandi, icyayi cy'icyatsi kibisi cyasanze ari isoko itanga icyizere cya antioxydants ikoreshwa neza mu kongera imiti igabanya ubukana bwa antioxydeant, nk'uko Dr. Wijeratne abivuga.
Ku bwe, umubyibuho ukabije ni wo nyirabayazana w'indwara nyinshi, zirimo indwara z'umutima zifata umutima, umuvuduko ukabije w'amaraso, diyabete iterwa na insuline, imikorere mibi y'ibihaha, osteoarthritis n'ubwoko bumwe na bumwe bwa kanseri. Icyayi catechine, cyane cyane EGCG, gifite umubyibuho ukabije n'ingaruka zo kurwanya diyabete. Dr. Wijeratne yavuze ko icyayi kibisi nacyo gifatwa nk'icyatsi gisanzwe gishobora kongera ingufu no gukoresha amavuta mu kugabanya ibiro, Dr. Wijeratne, akomeza avuga ko guhuza ibimera byombi bishobora gutanga inyungu nyinshi ku buzima.
