It volatile compounds could be used as markers for the overall quality evaluation of all green teas, according to the study of "Predication of Japanese green tea (Sen-cha) ranking by volatile profiling using gas chromatography mass spectrometry and multivariate analysis" by Jumtee K, Komura H, Bamba T, Fukusaki E.[1].
Green Sencha Health Benefits
21. Antidepressant Properties
a. In the observation of the effects of Green tea consumption and psychological distress of the study of "Green tea consumption is associated with lower psychological distress in a general population: the Ohsaki Cohort 2006 Study" by Atsushi Hozawa, Shinichi Kuriyama, Naoki Nakaya, Kaori Ohmori-Matsuda, Masako Kakizaki, Toshimasa Sone, Masato Nagai, Yumi Sugawara, Akemi Nitta, Yasutake Tomata, Kaijun Niu, and Ichiro Tsuji[21a], researchers found that The odds ratio (with 95% CI) of developing psychological distress among respondents who consumed ≥5 cups of green tea/d was 0.80 (0.70, 0.91) compared with those who consumed <1 cup/d and concluded that Green tea consumption was inversely associated with psychological distress even after adjustment for possible confounding factors.
b. In the investigation of Green tea consumption and the risk of depressive symptoms of the study of "Green tea consumption is associated with depressive symptoms in the elderly" by Niu K, Hozawa A, Kuriyama S, Ebihara S, Guo H, Nakaya N, Ohmori-Matsuda K, Takahashi H, Masamune Y, Asada M, Sasaki S, Arai H, Awata S, Nagatomi R, Tsuji I.[20b], researchers found that the prevalence of mild and severe and severe depressive symptoms was 34.1% and 20.2%, respectively and concluded that a more frequent consumption of green tea was associated with a lower prevalence of depressive symptoms in the community-dwelling older population.
c. In the evaluation of the effects of (-)-Epigallocatechin gallate (green tea polyphenol) and acute stress responses of the study of "(-)-Epigallocatechin gallate attenuates acute stress responses through GABAergic system in the brain" by Adachi N, Tomonaga S, Tachibana T, Denbow DM, Furuse M., researchers found that EGCG on distress-induced vocalization were significantly attenuated by the GABAA receptor antagonist picrotoxin but not by the GABAB receptor antagonist CGP 54626 (3-N-(1-(3,4-dichlorophenyl)ethylamino)-2-hydroxypropyl cyclohexylmethyl phosphinic acid hydrochloride) and concluded that EGCG has sedative and hypnotic effects in the brain, partially through GABAA receptors, and consequently moderates an acute stress response.

13. Bad Breath
a. In the investigation of green tea extract on bad breath of the study of "The effect of green tea extract on the removal of sulfur-containing oral malodor volatiles in vitro and its potential application in chewing gum" by Zeng QC, Wu AZ, Pika J.[18a], researchers found that Adding 5% baking soda to green tea extract-containing chewing gum was found to buffer saliva pHs to 8.0 during 10 min of chewing. However, severe discoloration was observed and undesirable bitterness was perceived, most likely due to the polymerization of unencapsulated green tea polyphenols. Therefore, encapsulation of green tea extract is recommended for applications at elevated pHs.
b. In the evaluation of the effect of green tea and mouth air of the study of "Effect of green tea on volatile sulfur compounds in mouth air" by Lodhia P, Yaegaki K, Khakbaznejad A, Imai T, Sato T, Tanaka T, Murata T, Kamoda T.[19b], researchers wrote that green tea was very effective in reducing oral malodor temporarily because of its disinfectant and deodorant activities, whereas other foods were not effective.

In the evaluation of different doses of green tea extract and inflammatory bowel disease of the study of "Comparative evaluation of different doses of green tea extract alone and in combination with sulfasalazine in experimentally induced inflammatory bowel disease in rats" by Byrav DS, Medhi B, Vaiphei K, Chakrabarti A, Khanduja KL.[16a], researchers showed that green tea alone and in combination with sulfasalazine reduced inflammatory changes induced by tri nitro benzene sulfonic acid in rats.
b. In the examination of the role of polyphenols in gastrointestinal diseases of the study of "Polyphenols and gastrointestinal diseases" by Dryden GW, Song M, McClain C.[16b], researchers erote that Substantial in-vitro and animal studies support the beneficial effects of polyphenols in many gastrointestinal diseases. Well designed multicenter trials in humans, such as those called for in the 2005 National Institutes of Health Requests for Applications for Silymarin Centers, will be critical for defining the safety, appropriate dosing and therapeutic efficacy of such agents.
c. In the examination of flavonoid found a abundantly in green tea and intestinal neoplasia of the study of "Emerging role of bioflavonoids in gastroenterology: Especially their effects on intestinal neoplasia" by Hoensch HP, Oertel R.[16c], researchers found that Flavonoids can inhibit inflammatory pathways and could be useful for chronic inflammatory bowel diseases. Flavonoid deficiency syndromes could be therapeutic targets in the future.
d. In the evaluation of "(-)-epigallocatechin-3-gallate (EGCG), a green tea and gastrointestinal tract of the study of "Development of (-)-epigallocatechin-3-gallate (EGCG)-loaded enteric microparticles with intestinal mucoadhesive property" by Onoue S, Ochi M, Yamada S.[16d], researchers found that although significant improvement in chemical and metabolic stability of EGCG was observed in the EGCG/MS, possibly due to the controlled release and/or bioadhesion. From these findings, newly prepared EGCG/MS might be of clinical importance in both stabilizing and delivering EGCG for treatment of intestinal diseases.

a. In the determination of Green Tea-EGCG effects in HIV-1of the study of 'Green Tea-EGCG reduces GFAP associated neuronal loss in HIV-1 Tat transgenic mice" by Rrapo E, Zhu Y, Tian J, Hou H, Smith A, Fernandez F, Tan J, Giunta B.[15a], researchers found that that EGCG (300mg/kg/day) dramatically reduced astrogliosis as demonstrated by GFAP expression. This was accompanied by a mild reduction in activated microglia by Iba-1 staining and significant reduction in neuronal loss through apoptosis as demonstrated by MAP2 staining and Western blot analysis respectively.
b. in examination of the effects of EGCG and HIV-1 proteins gp120 of the study of "EGCG mitigates neurotoxicity mediated by HIV-1 proteins gp120 and Tat in the presence of IFN-gamma: role of JAK/STAT1 signaling and implications for HIV-associated dementia" by Giunta B, Obregon D, Hou H, Zeng J, Sun N, Nikolic V, Ehrhart J, Shytle D, Fernandez F, Tan J.[15b], researchers found that EGCG treatment of primary neurons from normal mice reduced IFN-gamma-enhanced neurotoxicity of gp120 and Tat by inhibiting JAK/STAT1 pathway activation and found to mitigate the neurotoxic properties of HIV-1 proteins in the presence of IFN-gamma in vivo.
c. In the investigation of green tea polyphenol epigallocatechin-3-gallate counteractsSources and HIV infection of the study of "The main green tea polyphenol epigallocatechin-3-gallate counteracts semen-mediated enhancement of HIV infection" by Hauber I, Hohenberg H, Holstermann B, Hunstein W, Hauber J., researchers found that EGCG appears to be a promising supplement to antiretroviral microbicides to reduce sexual transmission of HIV-1.
d. In the assessment of green tea catechin, epigallocatechin gallate (EGCG) and HIV-1 glycoprotein 120 to the CD4 molecule on T cells of the study of "Preclinical development of the green tea catechin, epigallocatechin gallate, as an HIV-1 therapy' by Nance CL, Siwak EB[15d], Shearer WT. researchers found that by preventing the attachment of HIV-1-glycoprotein 120 to the CD4 molecule, EGCG inhibits HIV-1 infectivity. Because this inhibition can be achieved at physiologic concentrations, the natural anti-HIV agent EGCG is a candidate as an alternative therapy in HIV-1 therapy.

a. In the evaluation of the effect of tea polyphenol (TP) on cognitive and anti-cholinesterase activity of the study of "Effects of green tea polyphenol on cognitive and acetylcholinesterase activities" by Kim HK, Kim M, Kim S, Kim M, Chung JH.[11a], researchers found that TP exhibited a dramatic inhibitory effect on acetylcholinesterase activity. This finding suggests that TP might be useful in the treatment of Alzheimer's disease.
b. In rhe investigation of green tea catechin, induces HO-1 by ARE/Nrf2 pathway in hippocampal neurons in protection of neurons against different models of oxidative damages of the study of "Modulation of Nrf2/ARE pathway by food polyphenols: a nutritional neuroprotective strategy for cognitive and neurodegenerative disorders" by Scapagnini G, Vasto S, Abraham NG, Caruso C, Zella D, Fabio G.[11b], researchers found that caffeic acid phenethyl ester and ethyl ferulate, are also able to protect neurons via HO-1 induction. These studies identify a novel class of compounds that could be used for therapeutic purposes as preventive agents against cognitive decline.
c. In the assessment of the combination of green tea extract and l-theanine (LGNC-07) in congitive effects of the study of "A combination of green tea extract and l-theanine improves memory and attention in subjects with mild cognitive impairment: a double-blind placebo-controlled study" by Park SK, Jung IC, Lee WK, Lee YS, Park HK, Go HJ, Kim K, Lim NK, Hong JT, Ly SY, Rho SS.[11c], researchers wrote that brain theta waves, an indicator of cognitive alertness, were increased significantly in the temporal, frontal, parietal, and occipital areas after 3 hours in the eye-open and reading states. Therefore, this study suggests that LGNC-07 has potential as an intervention for cognitive improvement.
d. In the evaluation of l-Theanine and its effects of Amyloid beta (Abeta)-induced neurotoxicity which is a major pathological mechanism of Alzheimer disease (AD) of the study of "l-Theanine, an amino acid in green tea, attenuates beta-amyloid-induced cognitive dysfunction and neurotoxicity: reduction in oxidative damage and inactivation of ERK/p38 kinase and NF-kappaB pathways" by Kim TI, Lee YK, Park SG, Choi IS, Ban JO, Park HK, Nam SY, Yun YW, Han SB, Oh KW, Hong JT.[11d], researchers suggested that the positive effects of l-theanine on memory may be mediated by suppression of ERK/p38 and NF-kappaB as well as the reduction of macromolecular oxidative damage. Thus, l-theanine may be useful in the prevention and treatment of AD.
e. In the determination of Green tea (-)-epigallocatechin-3-gallate(EGCG) and its effects of cognitive dysfunction of the study of "Green tea (-)-epigallocatechin-3-gallate inhibits beta-amyloid-induced cognitive dysfunction through modification of secretase activity via inhibition of ERK and NF-kappaB pathways in mice" by Lee JW, Lee YK, Ban JO, Ha TY, Yun YP, Han SB, Oh KW, Hong JT.[11e], researchers found that EGCG enhanced memory function and brain alpha-secretase activity but reduced brain beta- and gamma-secretase activities as well as Abeta levels. Moreover, EGCG inhibited the fibrillization of Abeta in vitro with a half maximal inhibitory concentration of 7.5 mg/L

In the evaluation of the antioxidant activity of green tea moderated consumption in the study of "Antioxidant effects of tea: evidence from human clinical trials" by Rietveld A, Wiseman S.[5c] researcher sfound that a substantial number of human intervention studies with green and black tea demonstrates a significant increase in plasma antioxidant capacity in humans approximately 1 h after consumption of moderate amounts of tea (1-6 cups/d).
d. In the investigation of epigallocatechin gallate (EGCG) in catechins of polyphenols of green tea and its scavengers of reactive oxygen species of the study of "Tea catechins and polyphenols: health effects, metabolism, and antioxidant functions" by Higdon JV, Frei B.[5d], researchers found that the effects of tea and green tea catechins on biomarkers of oxidative stress, especially oxidative DNA damage, appear very promising in animal models.
e. In the examination of catechins, theaflavins and thearubigins of polyphenols in green tea and its antioxidant activities of the study of "Antioxidant activity of tea polyphenols in vivo: evidence from animal studies" by Frei B, Higdon JV.[5e], researchers found that catechins are rapidly and extensively metabolized emphasizes the importance of demonstrating their antioxidant activity in vivo and in the oxidized DNA base, 8-hydroxy-2'-deoxyguanosine. In animal models of atherosclerosis, green and black tea administration has resulted in modest improvements in the resistance of lipoproteins to ex vivo oxidation.

Organic Tava Tea Researches - The Ingredients of Green Sencha Health Benefits - Diabetes
Written by Chanel M. contributed by Kyle J. Norton, All right reserve
Sencha is a type of decoct Japanese green tea, most popular tea in Japan, made from the dried tea leaves without grinding the tea leaves. It volatile compounds could be used as markers for the overall quality evaluation of all green teas, according to the study of "Predication of Japanese green tea (Sen-cha) ranking by volatile profiling using gas chromatography mass spectrometry and multivariate analysis" by Jumtee K, Komura H, Bamba T, Fukusaki E.[1],
Health Benefits of Green Sencha
4. Diabetes
a. In the assesesment of the effect of green tea (GT) on diabetes-induced retinal oxidative stress and proinflammatory parameters in rats of the study of "Green Tea Prevents Hyperglycemia-Induced Retinal Oxidative Stress and Inflammation in Streptozotocin-Induced Diabetic Rats" by Kumar B, Gupta SK, Nag TC, Srivastava S, Saxena R.[4a], researchers found that the beneficial effects of (GT) green tea suggest its potential role in the prevention and treatment of diabetic retinopathy in human subjects.
b. In the evaluation of Abstract Tea (Camellia sinensis) effects in type II diabetes management of the study of "Anti-Hyperglycemia Properties of Tea (Camellia sinensis) Bioactives Using In Vitro Assay Models and Influence of Extraction Time" by.Ankolekar C, Terry T, Johnson K, Johnson D, Barbosa AC, Shetty K[4b], researchers wrote that tea offers an attractive potential strategy to regulate postprandial hyperglycemia toward an overall dietary support for type 2 diabetes management.
c. In the assessment of green tea extracts improve insulin resistance in obese type 2 diabetics of the study of "Does supplementation with green tea extract improve insulin resistance in obese type 2 diabetics? A randomized, double-blind, and placebo-controlled clinical trial" by Hsu CH, Liao YL, Lin SC, Tsai TH, Huang CJ, Chou P.[4c], researchers found that GTE group had significant reductions in waist circumference (WC), HOMA-IR index, and insulin level, and a significant increase in the level of ghrelin.
d. In the investigation of ( - )-epigallocatechin gallate effects and the autoimmune-mediated destruction of pancreatic β-cells, leading to deficiency of insulin production of the study of "Epigallocatechin gallate delays the onset of type 1 diabetes in spontaneous non-obese diabetic mice" by Fu Z, Zhen W, Yuskavage J, Liu D.[4d], researchers showed that While EGCG did not modulate insulitis, it elevated the circulating anti-inflammatory cytokine IL-10 level in NOD mice. These findings demonstrate that EGCG may be a novel, plant-derived compound capable of reducing the risk of T1D (type I diabetes).
e. In the evaluation of the relationship between long-term tea intake and prevalence of type 2 diabetes of the study fo "Long-term tea intake is associated with reduced prevalence of (type 2) diabetes mellitus among elderly people from Mediterranean islands: MEDIS epidemiological study" by Panagiotakos DB, Lionis C, Zeimbekis A, Gelastopoulou K, Papairakleous N, Das UN, Polychronopoulos E.[4e], researchers found that that long-term tea intake is associated with reduced levels of fasting blood glucose and lower prevalence of diabetes, in a cohort of elderly people living in Mediterranean islands.
