Wuyi Cliff Oolong tea, the best of Oolong and one of 3 ingredients of Tava Tea, is a species of Camellia sinensis belonging to the family Theaceae, native the Wuyi Mountain area. Its leaves and leaf buds has been used as tea in Chinese culture and many places in the world, including Wuyi Rock Tea, Tie Guan Yin tea, Taiwan tea and Oolong tea, Iron Goddess of Mercy and other products in Fujian, etc.. Oolong can be bought as green or black tea but it is best known as a black tea in the process of withering under the strong sun and oxidation before curling and twisting.
Health Benefits
20. Antiaging and Longevity
Polyphenols found a abundant in Oolong tea plays an important role of anti-free radical as an antioxidant, but also is beneficial in anti-aging and longevity effects.
a. Antioxidants and healthy aging
In the assessment of mechanisms of aging and determinants of life span will help to reduce age-related morbidity and facilitate healthy aging of the study of "Hormesis, cellular stress response and vitagenes as critical determinants in aging and longevity" by Calabrese V, Cornelius C, Cuzzocrea S, Iavicoli I, Rizzarelli E, Calabrese EJ.[20a], researchers found that Dietary antioxidants, such as carnosine, carnitines or polyphenols, have recently been demonstrated to be neuroprotective through the activation of hormetic pathways, including vitagenes which can enhance defensive systems involved in bioenergetic and stress resistance homeostasis with consequent impact on longevity processes.
b. Antiatherogenic or antineoplastic agents
In the examination of Cellular senescence is characterized by cellular hypertrophy: cell growth in the absence of cell division of the study of "The potential influence of plant polyphenols on the aging process" by Cherniack EP.[20b], researcher found that plant polyphenols such as resveratrol, quercetin, butein, fistein, piceatannol, curcumin have been shown to lengthen the lifespan of invertebrates and concluded that many of these compounds have other potential beneficial effects on lifespan as antiatherogenic or antineoplastic agents.
c. Aging related diseases
In the evaluation of Age-associated changes within an individual are inherently complex and occur at multiple levels of organismal function of the study of "Polyphenols and aging" by Queen BL, Tollefsbol TO.[20c], researchers found that Polyphenols have also been shown to possess other anticancer properties such as specific cell-signaling actions that may stimulate the activity of the regulatory protein SIRT1. Additionally, polyphenolic compounds have demonstrated their inhibitory effects against chronic vascular inflammation associated with atherosclerosis and suggested that further investigation may yield a potential use for polyphenols as pharmacological interventions against specific age-associated diseases
