A Network Pharmacology published in 2023 in the journal F&S Science found that Combining Crila with green tea extract (EGCG) has been found to synergistically hinder the growth of human uterine fibroid cells. In the methodological process, human uterine leiomyoma (HuLM) cells were treated with varying concentrations of Crila, either alone or combined with epigallocatechin gallate (EGCG), employing various tests. Prominently, assays were performed to examine cell proliferation, with additional analyses conducted to measure protein and gene expressions of proliferation markers. The interaction of Crila and EGCG resulted in a notable reduction in HuLM cell viability, showing an increased inhibitory effect over singular treatments. This decrease in cell proliferation is attributed to a synergistic efficacy derived from using Crila and EGCG in combination. It was notably characterised by the reduced presence of the proliferation marker, proliferating cell nuclear antigen, both at the messenger RNA and protein levels. It was observed that the process does not induce cell apoptosis, implying that the cell viability reduction is primarily due to decreased cell proliferation.

A Case Report published in 2023 in the journal Journal of Personalized Medicine found that The combination of epigallocatechin gallate, vitamin B12, folic acid, and hyaluronic acid could effectively counter precancerous lesions of the uterine cervix caused by HPV infections. The methodology used in this research centred around treating a 39-year-old patient who had a history of HPV, cervix lesions, and multiple failed surgical attempts to treat the condition. The treatment plan applied was unique, utilizing a blend of epigallocatechin gallate, vitamin B12, folic acid, and hyaluronic acid, administered over an eight week period. The results showed promising effects, with the patient's histological and cytological analyses revealing only a chronic cervicitis instead of any malignant lesions or cellular dysplasia. Therefore, the necessity for invasive total hysterectomy was minimized, demonstrating the potential for the selected treatment plan to manage precancerous lesions of the uterine cervix.

A Randomised Controlled Trial published in 2023 in the journal Journal of Clinical Medicine found that A combination of epigallocatechin gallate, folic acid, vitamin B12, and hyaluronic acid may effectively clear HPV infections and cervical lesions in women. Forty women with persistent HPV infections and cervical lesions were enrolled in this study and were then divided into two groups. Women in the treatment group were given a 12-week treatment comprising of 200mg epigallocatechin gallate, 400µg folic acid, 1mg vitamin B12, and 50mg hyaluronic acid. In contrast, the control group received no treatment. A significant difference was noted between the two groups post-treatment. In the control group, the majority of women still had a Low-Grade Squamous Intraepithelial Lesion (LSIL) at the close of the study, with varying changes in viral DNA content. However, in the case of the treated group, most women had achieved full viral clearance, showing no signs of lesions post-treatment, thus highlighting the potential effectiveness of the treatment combination.

A Cohort Study published in 2023 in the journal Nutrients found that Epigallocatechin gallate (EGCG), a green tea component, showed potential in treating uterine fibroids and associated infertility without causing liver toxicity or folate deficiency. The study involved the pre-testing of a green tea substance known as Epigallocatechin gallate (EGCG) on a cohort of premenopausal women, aged 18 to 40, with and without uterine fibroids, in order to evaluate its safety. The subjects were randomized into three groups, each receiving different treatments. One group took just a daily dose of 800 mg of EGCG, one group combined this EGCG dose with 100 mg of Clomiphene citrate for five days, and the third group combined it with 5 mg of Letrozole for the same period. The results showed that none of the subjects displayed signs of drug-induced liver injury, and all had normal serum folate levels. Hence, the findings suggest that the daily intake of 800mg of EGCG, whether consumed alone or in combination with Clomiphene citrate or Letrozole for five days, is well-tolerated and not related to any liver toxicity or folate deficiency in women of reproductive age.

A Review Article published in 2022 in the journal Molecules found that Green tea's catechins demonstrate therapeutic effects against neurodegenerative diseases via anti-inflammatory, antioxidant actions, and activating diverse brain cellular pathways. The research primarily evaluates the effect of polyphenolic compounds found in green tea, known as catechins, on neurodegenerative diseases. By conducting several interventional and observational studies on humans, the research explores the anti-cancer, anti-obesity, antidiabetic, anti-inflammatory, and neuroprotective properties of these compounds. The biological, pharmacological, antioxidant, and metal chelating abilities of catechins, particularly their influence on different cellular pathways within the brain, are intensively studied. The results elucidate that catechins exhibit multiple neuroprotective effects. Their anti-inflammatory and antioxidant properties help to inhibit excessive production of cytokines, and inflammatory pathways, while also controlling metal ions and free radicals. Researchers have further established that catechins may curb the phosphorylation of the tau protein and aggregation of amyloid beta, both key markers in neurodegenerative diseases. Additionally, these compounds show potential in reducing alpha-synuclein levels and augmenting dopamine levels. Hence, they significantly contribute to the prevention and treatment of neurodegenerative diseases, including Alzheimer's, Parkinson's, multiple sclerosis, and cognitive deficits.

A Review Article published in 2022 in the journal International Journal of Molecular Sciences found that Compounds found in green tea, especially EGCG, show significant anti-cancer activity and hold promise as potential anticancer drugs or adjuvants to standard chemotherapy. The study used a combination of epidemiological and laboratory studies to examine the effects of catechins in green tea on combating cancer. The researchers focused their attention on the four main catechin derivatives found in green tea: epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate—the latter found to be most potent. Attention was given to the quantity of hydroxyl groups and the presence of certain structural groups in these compounds, and how these factors affected antioxidant activity. The study centered around the effects of catechins on tumor survival, proliferation, invasion, angiogenesis, and metastasis. By doing this, the researchers could observe the influence of the identified compounds on the various processes that lead to the development and spread of cancer. The main point of observation was the capacity of catechins to neutralize reactive oxygen species, a key facet in their anti-cancer activity.

A Systematic Review published in 2022 in the journal Food Science and Human Wellness found that Bioactive components in green tea have demonstrated potential neuroprotective effects and might play a role in preventing Alzheimer’s disease. In this study, the researchers focused on the potential preventative effects of bioactive compounds, specifically (-)-epigallocatechin-3-gallate, present in tea, on Alzheimer's disease (AD). This interest was based on recognition of the importance of lifestyle-related factors, including diet, in the primary prevention of AD. They compiled and analyzed the findings from various preclinical studies which pointed towards the neuroprotective qualities of these compounds. The results reveal an association between the consumption of green tea and a reduction in the risk of age-related cognitive decline and AD. However, these results do not establish a causal relationship. That is, while people who drink green tea appear to have lower rates of AD, the study cannot confirm that green tea consumption is the reason for this reduced prevalence. The researchers also emphasized that while the preventative effects of green tea were deduced from preclinical (animal) studies, human-based clinical trials yielded unsatisfactory evidence regarding tea's preventive or therapeutic effect on AD.

A Randomised Controlled Trial published in 2022 in the journal International Journal of Health Sciences found that Green tea extract, specifically epigallocatechin gallate, can inhibit tumor growth and enhance the quality of life in women suffering from uterine fibroids. A total of 75 reproductive-age women with symptomatic uterine fibroids were included in a prospective, randomized control trial. The selection of participants for either group, those receiving 900 mg of green tea extract or those receiving symptomatic treatment, was done via a random, blind method using sealed envelopes. This trial took place over a span of 4 months and the overall study lasted around 3 years. The results of the study showcased the potency of green tea extract, particularly EGCG, with special regard to its anticancer properties. These manifested as anti-inflammatory, antiproliferative, and antioxidant effects. It was found that the administration of EGCG managed to influence tumor growth pathways, indicating its efficacy in dealing with uterine fibroids. Moreover, another significant progression was observed in the quality of life for the women partaking in this trial. It was confirmed that the use of EGCG could bring about an overall improvement in the living conditions of these women, contributing towards a better, healthier life amidst the struggle with their condition.

A Review Article published in 2022 in the journal Acta Biomedica found that Dietary supplements are found to be a promising complementary treatment for endometriosis, thanks to their anti-inflammatory, anti-oxidant, and immune modulatory characteristics. The researchers conducted a comprehensive literature review and synthesized the effects of various dietary supplements. The list of supplements includes vitamin D, zinc, magnesium, omega 3, propolis, quercetin, curcumin, N-acetylcysteine, probiotics, resveratrol, alpha lipoic acid, vitamin C, vitamin E, selenium, and epigallocatechin-3-gallate. These were studied due to their known anti-inflammatory, anti-oxidant, anti-proliferative, and immune modulatory characteristics. In terms of discussion on the results, the findings from the comprehensive literature review, encompassing in vitro, animal and human studies, show that there might be significant potential for dietary supplements as a complementary treatment to conventional therapy for endometriosis. Each supplement displayed attributes contributing to the mitigation of endometriosis symptoms, whether it was through anti-inflammatory means, antioxidant effects, immune modulation or their anti-proliferative properties. Despite variations between different kinds of supplements, the overall consensus indicates these function as a helpful add-on in managing the disease.

A Clinical Study published in 2021 in the journal Scientific Reports found that Consumption of green tea enriched with a citrus polyphenol, α-glucosyl hesperidin, can prevent weight gain and reduce body mass index, especially in individuals under 50 years. The research involved a randomized, placebo-controlled, double-blinded, and parallel-group-designed clinical trial. Sixty healthy Japanese men and women aged between 30 and 75 were included in the study. They were instructed to consume a blend of green tea and α-glucosyl hesperidin (GT-gH). Each dosage contained 178 mg α-glucosyl hesperidin and 146 mg of an active ingredient of green tea, called EGCG. This protocol was followed for 12 weeks. Participants underwent physical, hematological, blood biochemical, and urine examinations to ensure safety. Discussion of findings showed that the GT-gH mixture played a significant role in weight management. By the end of 12 weeks, participants who consumed the GT-gH mix showed prevention in weight gain and a reduction in body mass index when compared to the control group. The anti-obesity effect was particularly observable in individuals aged below 50. These participants experienced lower levels of triglyceride, body fat percentage, and visceral fat levels, alongside a decrease in body weight, BMI, and blood LDL/HDL ratios.

A Systematic Review published in 2021 in the journal Molecules found that Green tea consumption has been found to be effective in preventing the contraction of influenza infections. To identify the potential benefits of green tea in influenza prevention, a methodical review and combined analysis of eight distinct research studies involving 5,048 participants was completed. The effect of green tea catechin treatment was tested against control conditions and assessed based on infection rates. Five of these studies were randomized controlled trials involving 884 participants and three were cohort studies with 2,223 participants. Subgroups such as those who gargled or took orally ingested forms of green tea were also analyzed separately. Further to this, the possibility of publication biases was evaluated using Begg's and Egger's tests. The results showed both the randomized trials and the cohort studies displayed significant preventative effects on influenza infection for those treated with green tea catechins. Notably, there was no evidence of non-uniformity within the data, reinforcing these findings. The pooled results of different consumption methods further supported these findings, showing no disparities among the subgroups. These results suggest the consumption of green tea has tangible prophylactic effects against influenza infection.

A Review Article published in 2021 in the journal Molecules found that Green tea and its chief bioactive component have the potential to improve certain female reproductive disorders such as endometriosis, polycystic ovary syndrome, and dysmenorrhea. The study reviews the beneficial effects of green tea and its major bioactive component on female reproductive disorders, focusing on endometriosis, polycystic ovary syndrome (PCOS), and dysmenorrhea. The research highlights the role of catechins, phenolic compounds found in tea, which have been known for their health benefits due to their high antioxidative properties. The green tea or its derivative works on endometriosis through anti-angiogenic, anti-fibrotic, anti-proliferative, and proapoptotic mechanisms. In the discussion of results, it was found that green tea not only enhances ovulation and reduces cyst formation in PCOS, but it also ameliorates generalised hyperalgesia, reduces plasma corticosterone levels, and mitigates uterine contractility in dysmenorrhea. Despite the promising findings, the study acknowledges the need for more comprehensive clinical trials to fully translate these findings into clinical practice.

A Review Article published in 2021 in the journal Molecules found that Green tea, coffee, wine, and curry have beneficial health effects due to the polyphenols they contain, which possess both antioxidant and pro-oxidant properties. The research leverages epidemiological studies, clinical trials, cell-based studies and animal tests to examine the effects of green tea, coffee, wine, and curry -- and their key polyphenols -- on human health. The polyphenols investigated include epigallocatechin gallate in green tea, chlorogenic acid in coffee, resveratrol in wine, and curcumin in curry. The study concentrates on the workings of these polyphenols, primarily focusing on reactive oxygen species (ROS), and how they perform both anti- and pro-oxidant functions, fundamentally influencing different enzymes and factors with health contributions. In the discussion of the results, it is mentioned that the anti-oxidative actions of these polyphenols assist in the scavenging of ROS and the downregulation of the nuclear factor-κB, yielding beneficial anti-inflammatory effects. Conversely, their pro-oxidant actions appear to elevate ROS production, encouraging the activation of 5'-AMP-activated protein kinase that regulates different enzymes and factors for health improvement. However, the exact mechanism of how these polyphenols exhibit either pro- or anti-oxidant effects remains unclear. Also, the research underscores that while many studies note their health benefits, some others show no positive effects on health conditions such as obesity, suggesting that outcomes could be influenced by various study factors.

A Review Article published in 2020 in the journal Molecules found that Shaded gardening of Japanese matcha creates high-quality tea with unique compounds that can boost physical and mental health. This study reviewed and compiled health benefits of matcha tea, a type of powdered green tea grown traditionally in Japan with plants shaded during growth. This shading process promotes the synthesis and accumulation of unique biologically active compounds, which includes theanine, caffeine, chlorophyll, and a variety of catechins, with matcha offering a condensed source of these elements. The review indicated that matcha is considered the highest quality tea due to its distinctive chemical composition and prized flavor. In discussing the results, a major conclusion reached was that matcha tea has effective health-promoting attributes due to the tea's high content of antioxidant and anti-inflammatory substances. Such benefits have largely been credited to its significant proportion of catechins - a type of phenolic compound beneficial to human health. The high antioxidant potential of the tea and its subsequent ability to help prevent various diseases and support cognitive function underscores the value in regular consumption of matcha for not only physical health, but also mental health.

A Experimental Study published in 2020 in the journal Bioorganic Chemistry found that Green tea polyphenolic compounds, (-)-epigallocatechin (EGC) and (-)-epicatechin-3-gallate (ECG), can diminish harmful Alzheimer's disease linked Aβ aggregates and ameliorate symptoms. Green tea compounds EGC and ECG were tested for their effects on Cu/Zn-induced or self-assembled Aβ aggregation involved in Alzheimer's disease. To do so, a combination of thioflavine T fluorescent spectrometry, inductively coupled plasma mass spectrometry, UV-Vis spectroscopy, transmission electron microscopy, silver staining, immunohistochemistry, and immunofluorescence assays were utilized. Findings indicate that these compounds bind mildly to Cu and Zn and reduce their caused or self-assembled Aβ aggregates. Moreover, these compounds were shown to manage neurotoxicity in mouse neuroblastoma Neuro-2a cells by decreasing the production of reactive oxygen species (ROS). From the findings, the EGC and ECG in green tea showed potential in reducing the toxicity of Aβ oligomers and fibrils which are heavily linked to Alzheimer's disease. Notably, ECG has the ability to traverse the blood-brain barrier and reduce Aβ plaques within the mouse brain, showcasing its potential for neuron protection. This study highlights the potential of green tea - specifically, its polyphenolic compounds - in the prevention or reduction of Alzheimer's disease symptoms.

A Review Article published in 2020 in the journal Antioxidants found that Catechins in green tea potentially counteract osteoporosis by negatively affecting bone loss processes and enhancing bone formation processes. The research paper explores the role of catechins, a key compound found in green tea, in combating osteoporosis. In an endeavour to understand the cellular processes, the research focuses on the two critical processes involved in the onset of osteoporosis: osteoblastogenesis, the process of bone formation, and osteoclastogenesis, the process of bone resorption. Specifically, the research emphasizes that inflammation and high reactive oxygen levels enhance osteoclastogenesis while concurrently reducing osteoblastogenesis. Green tea catechins, which have strong antioxidant and anti-inflammatory properties, are assumed to rebalance these two processes. The discussions revolve around the potential of green tea catechins to curb osteoclastogenesis by increasing the rate of osteoclast apoptosis, hampering osteoclastogenesis, and impeding bone resorption in a controlled environment. This is achieved directly through interactions with pre-osteoclasts/osteoclasts or indirectly through regulation of pre-osteoclasts via mesenchymal stem cells (MSCs) or stromal cells. Furthermore, catechins are credited with boosting osteoblastogenesis by enhancing the osteogenic differentiation of MSCs and improving osteoblastic survival, proliferation, differentiation, and mineralization. The paper verifies the positive in-vitro effects of catechins on osteogenesis through various animal models and human observational studies.

A Review Article published in 2020 in the journal The Journal of Nutritional Biochemistry found that Catechin-rich green tea extract (GTE) exercised anti-inflammatory activities can be beneficial in managing Nonalcoholic fatty liver disease (NAFLD) by reducing liver injury and gut-derived endotoxins. The research is built around the study of the anti-inflammatory properties of catechin-rich green tea extract (GTE). The primary analytical interest is its effects on inflammatory responses that contribute to Nonalcoholic fatty liver disease (NAFLD), specifically nonalcoholic steatohepatitis (NASH). The extraction focuses on inhibiting the activation of the hepatic nuclear factor kappa-B, which is known to exacerbate liver injury. The results have shown positive contributions of GTE to management of NAFLD. Itn was observed that the extract limits the activation of the hepatic nuclear factor kappa-B and in turn, reduces NASH-associated liver injury. Additionally, green tea extract was found to contain hepatic-level benefits that attenuate intracellular redox distress and pro-inflammatory signaling. It was also found to improve the gut barrier function, limit the translocation of gut-derived endotoxins, and exercise prebiotic and antimicrobial effects on the gut microbial ecosystem. These results can potentially contribute to managing NAFLD-associated morbidity.

A Review Article published in 2020 in the journal Antioxidants found that Green tea catechins potentially contribute to maintaining joint and skeletal muscle health, mitigating symptoms of osteoarthritis and sarcopenia. The research begins by providing an understanding of osteoarthritis, a degenerative inflammatory disorder of articular cartilage, and sarcopenia, a condition characterized by loss of muscle mass and strength. It explores their prevalence, causes such as excessive inflammation and oxidative stress, mitochondrial dysfunction, and diminished autophagy. It then delves into the role of green tea catechins in joint health, including their influence on inflammatory signaling agents, anabolic mediators, and miRNAs expression. This leads to a decrease in chondrocyte death and collagen degradation, thereby offering cartilage protection. The investigation also examines the effects of green tea catechins on skeletal muscle health. It highlights their role in maintaining an equilibrium between protein synthesis and degradation, and enhancing the synthesis of mitochondrial energy metabolism. The review thus suggests a positive impact of green tea catechins on joint and muscle health, helping to maintain favorable muscle homeostasis and reduce muscle atrophy associated with aging. It ends by pointing out the limitations of the current study and proposing future research directions.

A Experimental Study published in 2020 in the journal Molecules found that The major components of green tea and coffee, EGCG and CGA respectively, may have anti-cancer effects, though these effects seem to vary for different types of cancer. Studies were conducted across cell-based and animal trials to explore the health benefits, particularly in anticancer effects, of epigallocatechin gallate (known as EGCG) and chlorogenic acid (CGA), the predominant elements in green tea and coffee, respectively. It was observed that the results were inconsistent due to possible confounding factors. A conceivable mechanism suggested, a part of those shared between EGCG and CGA, was related to the alterations in reactive oxygen species. However, the variance in the anti-cancer effects may be attributed to the different target molecules of EGCG and CGA, signifying the site-specific differences of anti-cancer effects observed in human studies.

A Randomised Controlled Trial published in 2020 in the journal Molecules found that Daily consumption of decaffeinated green tea catechins may enhance working memory. The study incorporated a double-blind, randomized, controlled approach to determine the effects of 336.4 mg of decaffeinated green tea catechins on cognitive function. It targeted Japanese adults, aged 50 to 69 years, exhibiting a Mini-Mental State Examination Japanese version score of over 24 and who self-identified as having cognitive decline. The experiment comprised administering a substance and then examining the cognitive function post a single dosage as well as following 12 weeks of everyday consumption. The Cognitrax testing battery was utilized to assess cognitive function. In the results, it was observed that the incorrect response rate on the Continuous Performance Test significantly fell after a single dosage of green tea catechins. After 12 weeks of regular intake, the response duration for the two-back test in Part 4 of the 4-part Continuous Performance Test reduced, indicating potential improvement in working memory. The data suggests that consuming green tea catechins daily may potentially lead to cognitive enhancements, particularly in working memory.

A Systematic Review published in 2020 in the journal Journal of Herbal Medicine found that Green tea catechins-containing mouthwash may potentially be a practical alternative to chlorhexidine due to its efficacy in plaque reduction and minimal side effects. The methodology involved an exhaustive literature review of several electronic databases, such as CINAHL, Cochrane Library, MEDLINE, PubMed and Scopus, up until January 2017. This review adhered to the PRISMA criteria, centring the research question around the impact of green tea catechins-containing mouthwash on plaque accumulation and gingival inflammation in patients with gingivitis. Out of the 187 titles identified this way, five were fit for meta-analysis, the subject matter primarily revolving around an Asian population. The results indicated that both green tea and chlorhexidine (CHX) significantly outperformed a placebo in reducing Plaque Index (PI), with no substantial contrast between the CHX and green tea groups, both in terms of the endpoint and the change from the beginning of the study to its conclusion. However, only minor side effects were associated with the green tea mouthwash. Contrarily to chlorhexidine, this aspect might make green tea mouthwash more suitable for prolonged use. Despite some heterogeneity in the data and potential bias risks, green tea mouthwash remains an interesting, viable alternative worth considering.

A Systematic Review published in 2020 in the journal Phytotherapy Research found that Green tea influences liver enzymes differently based on an individual's health status, reducing levels in patients with Nonalcoholic Fatty Liver Disease, but slightly increasing levels in healthy subjects. The researchers initiated a comprehensive review and analysis of randomized clinical trials relating to green tea supplementation's effects on liver enzymes. This analysis included forms of green tea supplementation, such as catechin. The information to support this examination was sourced from four medical and health databases and included all trials examining the influence of green tea or its derivatives on specific liver enzymes, including Alanine Transaminase, Aspartate Aminotransferase, Alkaline Phosphatase, and Bilirubin. Altogether, fifteen trials were considered for inclusion in this research. The study found that while the overall effect of green tea on liver enzymes was nonsignificant, further analysis showed that the impact of green tea on liver enzymes varies depending on an individual's health status. Notably, the use of green tea reduced liver enzyme levels in participants diagnosed with Nonalcoholic Fatty Liver Disease. However, in contrast, a small but statistically significant increase in liver enzyme levels was observed in healthy subjects. These findings suggest that the therapeutic potential of green tea may differ significantly based on an individual's health condition.

A published in 2018 in the journal Experimental and Therapeutic Medicine found that The polyphenol epigallocatechin-3-gallate (EGCG) inhibits the growth of cervical carcinoma cell lines potentially by altering the expression of micro-RNAs, indicating its potential as an anti-cervical cancer drug. In the methodology, an MTT assay was used to measure cell proliferation and examine the inhibitory effects of EGCG, a polyphenol, on the growth of cervical carcinoma for HeLa cells subjected to a range of EGCG concentrations. The study also assessed the associated regulation of various microRNA expression involving HeLa, SiHa, CaSki and C33A cell lines, using quantitative polymerase chain reaction (PCR) analyses. The results revealed that the growth of HeLa cells was significantly reduced by EGCG in a dose- and time-dependent manner. Further, the study found noteworthy changes in the expression of particular microRNAs in various cell lines due to EGCG treatment. It was observed that certain microRNAs were significantly downregulated while others were upregulated. Therefore, the study suggests that EGCG likely suppresses the growth of cervical carcinoma cells by potentially regulating the expression of micro-RNAs.

A Review Article published in 2018 in the journal Molecules found that (-)-Epigallocatechingallate (EGCG), a natural product, has potent anti-proliferation, anti-metastasis, and pro-apoptosis effects on cervical cancer cells, enhancing the effects of conventional drugs. This research paper discusses the potential of (-)-epigallocatechingallate (EGCG), a naturally occurring compound, as an anti-cancer treatment for cervical cancer. Traditional treatment methods involve the use of chemotherapy, but these have high toxicity and numerous side effects. The inherent low toxicity of EGCG makes it a promising alternative for treatment. The paper reviews the mechanisms by which EGCG inhibits the growth and spread of cervical cancer cells and promotes their apoptosis. Furthermore, the synergistic pharmaceutical effects of EGCG with conventional agents including cisplatin and bleomycin, have been evaluated. For the discussion of results, the research shows significant evidence of EGCG's abilities to inhibit growth and spread of cervical cancer cells as well as initiate programmed cell death, or apoptosis. The compound's synergistic properties when paired with conventional chemotherapy drugs such as cisplatin and bleomycin, further enhance its potential as a treatment method. The review also explains the underlying processes by which EGCG performs these roles, providing a comprehensive view on its potential applications in cervical cancer treatment.

A published in 2018 in the journal Nutrients found that The consumption of epicatechin, plentiful in foods like cocoa, positively influences memory, executive function, and processing speed, particularly in older adults. Methodology: The research design for this paper was anchored on the use of intervention studies. These are intensive studies purposed to test breakthrough methodologies or practices on a select group of participants. In this case, the intervention was the ingestion of epicatechin, a compound found largely in cocoa. The subjects monitored were mostly from a more mature demographic, aged 50 years and above. The studies selected for review were those that lasted a minimum of 28 days to ensure an adequate examination period and only those which had a daily epicatechin dose exceeding 50 mg. Discussion of Results: The paper notes an appreciable improvement in the cognitive performance in those subjects who consumed diets high in epicatechin. More specifically, there was an enhancement in memory, executive function, and processing speed. Trends showed that these benefits were more conspicuous in studies which offered more than 50 mg of epicatechin daily, and ran for at least 28 days. The results were particularly noteworthy in the elderly population, where all participants showed cognitive improvement. The impact of epicatechin on cerebral blood flow, however, could not be definitively proved and the results suggest its role requires further exploration. Additionally, the synergistic effects of epicatechin with other dietary elements also complicated the ability to attribute the cognitive improvement to this compound alone.

A Review Article published in 2018 in the journal Molecules found that Tea catechins, found in green tea, may reduce the rates of influenza infection and diminish certain cold symptoms. The research methodology started with interpreting several experimental studies which reported that tea catechins can inhibit influenza viral adsorption and suppress replication and neuraminidase activity. These catechins were also found effective against some common cold viruses and helped to enhance immunity against such viral infections. Additionally, epidemiological studies conducted since the late 1990s were examined which suggested that regular consumption of green tea may decrease influenza infection rates and some cold symptoms, and gargling with tea catechin could potentially protect against the development of influenza infection. For the discussion of results, the studies collectively showed that tea catechins have potential antiviral activity against influenza and some cold viruses. Although clinical evidence supporting these effects remained unconclusive, the review showed promising trends. The consumption of green tea and gargling with tea catechins could lead to potentially decreased rates of influenza infection and lessened cold symptoms according to the analyzed epidemiological studies.

A Systematic Review published in 2018 in the journal Beverages found that Among the health benefits of green tea are: anticarcinogenic, anti-inflammatory, antimicrobial, and antioxidant properties, and benefits in cardiovascular disease and oral health. Green tea catechins have proved to be very versatile in providing health benefits. This means that there are potential health benefits for everyone in the consumption of green tea. Even moderate amounts of consumption (drinking 1–2 cups of tea per day) may have benefits. It is a very good thing that it is the second most popular beverage worldwide, as the differences in health in a world without green tea might be significant. There is fortunately a wide variety of research being performed using green tea catechins, and we are starting to see many studies performed using human subjects, as it is extremely important that we are able to show the direct benefits to humans. The expansive repertoire of green tea activity in health is important, especially to those people who live where medical assistance is not generally available or affordable.

A Systematic Review published in 2017 in the journal Phytomedicine found that Green tea consumption was shown to reduce psychopathological symptoms like anxiety and was also shown to effect cognition, with noted benefits for memory and attention. Green tea was also linked with the activation of working memory as seen in functional MRI. The effects of green tea cannot be attributed to a single constituent of the beverage. This is exemplified in the finding that beneficial green tea effects on cognition are observed under the combined influence of both caffeine and l-theanine, whereas separate administration of either substance was found to have a lesser impact.

A Randomised Controlled Trial published in 2015 in the journal Food and Chemical Toxicology found that Green tea extract consumption can potentially cause mild adverse reactions, notably nausea, skin conditions, and increased alanine aminotransferase levels. In our study, we utilized a randomized, double-blind, and placebo-controlled method. We selected 1075 postmenopausal women to participate over the course of one year. They were randomly assigned to daily consumption of green tea extract containing a specified quantity of epigallocatechin gallate (EGCG) or a placebo. With regards to the results, there was no significant difference observed with general adverse events between those consuming the green tea extract and those taking the placebo. However, it was recognized that those women taking the green tea extract reported a higher incidence of nausea and skin conditions, but a lower occurrence of diarrhea. More women in the green tea extract group experienced an elevation in alanine aminotransferase levels. Overall, adverse events were mainly mild and transient, highlighting a general tolerance for daily consumption of GTE. Yet, it was noted that a small percentage of GTE consumers experienced elevated alanine aminotransferase levels, including a few serious cases.

A Systematic Review published in 2014 in the journal Pharmacology found that Green tea polyphenols may enhance effectiveness of specific breast cancer endocrine treatments through both estrogen-dependent and -independent mechanisms. The methodology used in this systematic review involved a comprehensive search for relevant studies across various electronic databases. The search terms used were tailored to uncover data specifically regarding the interaction of green tea catechins with breast cancer endocrine treatment. Importantly, this review was focused on experimental trials which studied the synergistic effects of green tea catechins and certain breast cancer treatments, namely tamoxifen and raloxifene. The analysis of results indicated that green tea catechins potentially work in conjunction with tamoxifen or raloxifene—used for treating both estrogen receptor-positive and receptor-negative breast cancer—via mechanisms that may depend or not depend on the estrogen receptor. At the same time, the review found no existing evidence showing any interaction of green tea catechins with aromatase inhibitors or fulvestrant. Notably, given their nature as natural compounds and their known safety profile, green tea catechins used along with tamoxifen could constitute a viable direction for enhancing chemoprevention, adjuvant, and metastatic breast cancer treatments.

A Randomised Controlled Trial published in 2013 in the journal International Journal of Women's Health found that Green tea extract has shown promising results in reducing uterine fibroid volume, fibroid-related symptoms, and improving quality of life in women with symptomatic uterine fibroids. The research examined the effect of green tea extract (epigallocatechin gallate, EGCG) on uterine fibroid (UF) management. In this randomized, double-blinded, placebo-controlled study, 39 women aged 18-50 presenting with symptomatic UF were enlisted. Participants were confirmed as eligible through transvaginal ultrasonography that showed at least one 2cm³ or larger fibroid lesion. They were split into two groups: the focus group took a daily oral intake of 800 mg of green tea extract, while the control group followed the same regimen with 800 mg of brown rice (placebo). The experiment period ran for four months. At the end, UF volume changes were also measured through transvaginal ultrasonography for comparison. The outcome revealed divergent changes in UF volume and health-related quality of life (HRQL) among participants. In the placebo group, an increase in fibroid volume was noticed. Contrarily, significant reductions in fibroid volume and symptom severity were recorded in women who took green tea extract. This group also witnessed an improvement in HRQL contrasted to the control group. Additionally, anemia improved in the EGCG treatment group, with no adverse effects or endometrial anomalies reported in either group.

A Systematic Review published in 2011 in the journal Journal of the Academy of Nutrition and Dietetics found that The consumption of green tea catechins is associated with a statistically significant reduction in total and LDL cholesterol levels. Twenty trials (N=1,415) met all inclusion criteria. Upon meta-analysis, GTCs at doses ranging from 145 to 3,000 mg/day taken for 3 to 24 weeks reduced total and LDL cholesterol compared to control. GTCs did not significantly alter HDL cholesterol or triglyceride levels. The consumption of GTCs is associated with a statistically significant reduction in total and LDL cholesterol levels; however, there was no significant effect on HDL cholesterol or triglyceride levels.

A Experimental Study published in 2003 in the journal Journal of Chromatography A found that Matcha tea holds nearly 137 times the concentration of epigallocatechin gallate, an important catechin, compared to common green teas. Researchers devised a fast method to evaluate the presence of five key catechins and caffeine in matcha using micellar electrokinetic chromatography. This analytical process examined matcha in both its water-based and methanol extractions, and then it was juxtaposed with the outcome of a water extraction of a popular green tea. The comparison was made basing it on a milligram catechin per gram of dry leaf parameter. In lieu of the data results from this methodology, it was observed that the available concentration of epigallocatechin gallate, a major catechin, from consuming matcha significantly surpassed - by 137 folds - the quantity obtainable from a well-known green tea called 'China Green Tips.' Furthermore, it also exceeded by at least three times the largest concentration reported in other green teas, according to existing literature. These results underscore matcha's significantly higher health potential when compared to other conventional green teas.
