Ua ʻike ʻia ma kahi noiʻi na Kauka Samira Samarakoon o ka Institute of Biochemistry, Molecular Biology and Biotechnology ma ke Kulanui o Colombo a me ke kauka meaʻai kaulana ʻo Kauka DBT Wijeratne he nui nā pono olakino o ka inu ʻana i ke kī ʻōmaʻomaʻo me Centella asiatica. Hoʻonui ʻo Gotu kola i nā waiwai antioxidant, antiviral a me ka hoʻoikaika ʻana i ka pale ʻana o ke kī ʻōmaʻomaʻo.
Ua manaʻo ʻia ʻo Gotu kola he lāʻau lapaʻau no ka lōʻihi o ke ola a he mea nui ia o ka lāʻau lapaʻau kuʻuna ʻAsia, ʻoiai ʻo ke kī ʻōmaʻomaʻo kekahi o nā mea inu olakino kaulana loa o ka honua. Ua ʻike nui ʻia nā pono olakino o ke kī ʻōmaʻomaʻo a ua hoʻopau nui ʻia e ka poʻe he nui ma muli o kona mau waiwai antioxidant, ka hoʻemi ʻana i ka momona, ka pale ʻana i ka maʻi ʻaʻai, ka hoʻohaʻahaʻa ʻana i ke koko, a me nā mea hou aku. Pēlā nō, ua ʻike nui ʻia nā pono olakino o ke kola ma nā hana lapaʻau kahiko o India, Iapana, Kina, Indonesia, ʻApelika Hema, Sri Lanka, a me ka Pākīpika Hema. Ua hōʻoia nā hoʻokolohua hoʻokolohua hou he mau waiwai antioxidant ko ke kola, he maikaʻi no ke akepaʻa, pale i ka ʻili, a hoʻomaikaʻi i ka ʻike a me ka hoʻomanaʻo. Ua ʻōlelo ʻo Kauka Samarakoon i ka wā e inu ai i ka hui ʻana o ke kī ʻōmaʻomaʻo a me ka cola, hiki i kekahi ke loaʻa nā pono olakino āpau o nā mea ʻelua.
Ua ʻōlelo ʻo ia ʻaʻole pono e loaʻa i ka Coca-Cola ma mua o 20 pakeneka o ka hui ʻana ma muli o ka emi ʻana o ka ʻae ʻia ʻana e like me ka mea inu.
Ua ʻōlelo ʻo Kauka Vieratne ua hōʻoia nā haʻawina mua he hopena maikaʻi ka ʻai ʻana i ka gotu kola i ka hoʻomaikaʻi ʻana i ke olakino o ke ake, ʻoi aku hoʻi i nā ʻano maʻamau o ke kanesa ate mua, ka hepatocellular carcinoma, ka momona o ke ake a me ka cirrhosis. Hōʻike pū nā haʻawina hou e hiki i ka cola ke kōkua i ka hoʻohaʻahaʻa ʻana i ke koko a me ka hoʻemi ʻana i ka pilikia o nā maʻi cardiovascular, me ka hahau ʻana, ka myocardial infarction, a me ka maʻi coronary heart. Ua hōʻike nā haʻawina pharmacological hiki i ka kola extract ke hoʻoponopono i ka hana o ka ʻōnaehana nerve waena a hoʻomaikaʻi i nā hana cognitive o ka lolo.
Ua kuhikuhi ʻo Kauka Wijeratne ua ʻike nui ʻia nā pono olakino o ke kī ʻōmaʻomaʻo a puni ka honua. Nui aʻe nā noiʻi ʻepekema e pili ana i nā pono olakino o ke kī ʻōmaʻomaʻo ma mua o ka gotu kola. Waiwai nui ke kī ʻōmaʻomaʻo i nā catechins, polyphenols, ʻoi aku ka epigallocatechin gallate (EGCG). He antioxidant ikaika ʻo EGCG hiki ke pepehi i nā cell cancer me ka ʻole o ka hōʻino ʻana i nā cell maʻamau. He kūpono hoʻi kēia hui i ka hoʻohaʻahaʻa ʻana i ka cholesterol lipoprotein haʻahaʻa, ka pale ʻana i nā clots koko maʻamau ʻole, a me ka hōʻemi ʻana i ka platelet aggregation. Eia kekahi, ua ʻike ʻia ka ʻōmole kī ʻōmaʻomaʻo he kumu hoʻohiki o nā antioxidants kūlohelohe i hoʻohana pono ʻia e hoʻonui i nā waiwai antioxidant, wahi a Kauka Wijeratne.
Wahi a ia, ʻo ka momona ke kumu nui o nā maʻi he nui, me ka maʻi puʻuwai coronary, ke koko kiʻekiʻe, ka maʻi diabetes non-insulin-dependent, ka hana ʻino o ka māmā, ka osteoarthritis a me kekahi mau ʻano maʻi kanesa. Loaʻa i nā catechins kī, ʻoiai ʻo EGCG, nā hopena anti-obesity a me anti-diabetic. Ke nānā ʻia nei ke kī ʻōmaʻomaʻo ma ke ʻano he lau nahele kūlohelohe e hiki ke hoʻonui i ka hoʻolilo ʻana i ka ikehu a me ka hoʻoheheʻe ʻana o ka momona no ka pohō kaumaha, wahi a Kauka Wijeratne, me ka hoʻohui ʻana e hiki i ka hui pū ʻana o nā lau nahele ʻelua ke hāʻawi i nā pono olakino he nui.
