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.

Review Article EGCG Green Tea Period Pain
The paper reviews the role of the compound Epigallocatechin-3-gallate found in green tea, and its effects on various benign gynecological conditions. The compound is noted for its antioxidant and prooxidant qualities, allowing it to interact with multiple cellular pathways that are crucial for disease pathogenesis. The studied conditions include uterine fibroids, endometriosis, dysmenorrhea, adenomyosis, menopause, and polycystic ovary syndrome. The research accounts for the specific mechanisms through which the compound might affect each condition, such as anti-fibrotic, anti-angiogenic, and pro-apoptotic mechanisms.
The results suggest that green tea consumption can lead to improved symptom management in these disorders. It was found to lessen the intensity of symptoms associated with uterine fibroids and endometriosis, by invoking anti-fibrotic, anti-angiogenic, and pro-apoptotic mechanisms. It also helped manage pain linked with dysmenorrhea and adenomyosis through reducing uterine contractility and widely felt pain. Additionally, it showed efficacy in weight and osteoporosis control during menopause, and showed potential benefits in managing polycystic ovary syndrome. However, claims regarding its influence on fertility were deemed controversial.
Combining Crila with green tea extract (EGCG) has been found to synergistically hinder the growth of human uterine fibroid cells.

Network Pharmacology EGCG Uterine Fibroids
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.

Case Report Cervical Cancer Cervical Dysplasia Cervical Lesions
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.

Randomised Controlled Trial EGCG Green Tea 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.

Review Article Anti-Inflammatory Antioxidant EGCG
The main research methodology of this work is a narrative review. The paper comprehensively collects and reviews various preclinical studies that propose the use of green tea as a potential treatment for endometriosis. These studies explore the diverse biological properties and activities of green tea and its major bioactive component, (-)-epigallocatechin gallate, including anti-angiogenic, anti-proliferation, anti-metastasis, and apoptosis induction functions. Different potential mechanisms used by green tea to inhibit the growth of endometriosis are considered, such as its effects on inflammation, oxidative stress, invasion, adhesion, and apoptosis.
The discussion of the reviewed data highlights the potential therapeutic effects of green tea acting on different molecular and cellular mechanisms in endometriosis. The researchers keenly discussed how green tea exhibited an inhibitory effect on the disease through multiple avenues, including reducing inflammation and oxidative stress, preventing tumor invasion and adhesion, promoting apoptosis (cell death), and limiting angiogenesis (the development of new blood vessels) - all these factors contribute to the growth and progression of endometriosis. The discussion elaborates on the significant roles and wider implications of these processes in understanding and potentially treating endometriosis.
