Agricultural and Biological Chemistry.  1989.  Volume 53, No. 9 pp. 2307-2311 – An extract of Japanese green tea, one of the most popular drinks in Japan, was an inhibitor of the growth of Streptococcus mutans, a bacterium responsible for causing dental caries. The analysis of the extract revealed that the main antibacterial components of the extract were several polv phenolic compounds, especially gallocatechin (GC), epigallocatechin (EGC), and epigallocatechin gallate (EGCg). GC was the most active component and its minimum inhibitory concentration against the bacterium was around 250 μg per ml.

“Traiditionally in Japan individuals drink green tea after a meal.  This is said to have a cleansing effect on the teeth and mouth.  This research article shows how green tea does in fact help in the prevention of cavaties.  The most popular antioxidant from green tea, EGCG, usually gets all the attention, but in this case GC (gallocatechin) deserves the majority of the credit.  GC inhibits the growth of a certain bacteria that causes dental cavaties.” – Josh Smith

Can green tea do that? A literature review of the clinical evidence.  Preventive Medicine 49 (2009) 83–87 

Objective. Habitual green tea consumption has long been associated with health benefits including chemoprevention and cardiovascular protection. This non-systematic literature review presents the clinical evidence to date. Method. A literature review of peer-reviewed articles on observational and interventional studies was conducted to include green tea, its extract or its purified polyphenol (−)-epigallocatechin-3-gallate (EGCG). Electronic databases searched included PubMed (1966–2009) and the Cochrane Library (Issue 4, 2008). Results: observational studies are inconclusive on the benefits of habitual consumption of green tea in the prevention of most cancers. However, there are trends towards prevention in breast and prostate cancers. Interventional studies have demonstrated reduction in relapses following surgical resection in colorectal adenomas and increased survival rates in epithelial ovarian cancer. Observational studies indicate that green tea may provide protection against hypertension and reduce the risk for stroke, and interventional studies are providing biochemical and physiological evidence. Conclusion. Although the overall clinical evidence is inconclusive, habitual green tea consumption may be providing some level of chemoprevention in prostate and breast cancer. Green tea may also attenuate the risk factors association with the development of atherosclerosis thus reducing the incidence of cardiovascular events and stoke.

“Taking a look at the clinical trials that have been conducted on green tea so far with such technical topics as cancer, hypertension and atherosclerosis, there are great emerging results of daily consumption of green tea.  400 milligrams of EGCG is the amount of antioxidants from green tea that have been identified as the “right amount”.  – Josh Smith 

Green Tea and Skin.  Säntosh K. Katiyar, PhD; Nihal Ahmad, PhD; Hasan Mukhtar, PhD.  Arch Dermatol. 2000; 136:989-994. 

Objective: To discuss the current knowledge of polyphenolic compounds present in green tea as anti-inflammatory, antioxidant, and anticarcinogenic in skin. Data Sources: References identified from bibliographies of pertinent articles, including our work in related fields. Study Selection and Data Extraction:  Articles were selected based on the use of green tea or its polyphenolic constituents for prevention against inflammation and cancer in the skin. Also discussed is the possible use of green tea to treat various inflammatory dermatoses. Data Synthesis: The polyphenolic compounds from green tea were tested against chemical carcinogenesis and photocarcinogenesis in murine skin. These green tea polyphenols were found to afford protection against chemical carcinogenesis as well as photocarcinogenesis in mouse skin. A few experimental studies were conducted in human skin in our laboratory. Analysis of published studies demonstrates that green tea polyphenols have anti-inflammatory and anticarcinogenic properties. These effects appear to correlate with antioxidant properties of green tea polyphenols. Conclusions: The outcome of the several experimental studies suggests that green tea possess anti-inflammatory and anticarcinogenic potential, which can be exploited against a variety of skin disorders. Although more clinical studies are needed, supplementation of skin care products with green tea may have a profound impact on various skin disorders in the years to come.

“Finding effective ways to protect our skin is not only good for appearances, but taking care of the largest organ in our bodies is important!  Products that provide support against inflammation and light induced carcinogens should be a the top of everyone’s list!”  – Josh Smith

Green Tea: Nature’s Defense against Malignancies.  Critical Reviews in Food Science and Nutrition, 49:463–473 (2009).  Masood, S.  Sadiq, B.  National Institute of Food Science and Technology, University of Agriculture, Faisalabad.   

The current practice of introducing phytochemicals to support the immune system or fight against diseases is based on centuries old traditions. Nutritional support is a recent advancement in the domain of diet-based therapies; green tea and its constituents are one of the important components of these strategies to prevent and cure various malignancies. The anti-carcinogenic and anti-mutagenic activities of green tea were highlighted some years ago suggesting that it could reduce the prevalence of cancer and even provide protection. The pharmacological actions of green tea are mainly attributed to polyphenols that includes epigallocatechin-3-gallate (EGCG), epicatechin, epicatechin-3-gallate, epigallocatechin. Green tea and its components effectively mitigate cellular damage arising due to oxidative stress. Green tea is supposed to enhance humoral and cell-mediated immunity, decreasing the risk of certain cancers, and may have certain advantage in treating inflammatory disorders. Much of the cancer chemopreventive properties of green tea are mediated by EGCG that induces apoptosis and promotes cell growth arrest, by altering the expression of cell cycle regulatory proteins, activating killer caspases, and suppressing nuclear factor kappa-B activation. Besides, it regulates and promotes IL-23 dependent DNA repair and stimulates cytotoxic T cells activities in a tumor microenvironment. It also blocks carcinogenesis by modulating the signal transduction pathways involved in cell proliferation, transformation, inflammation and metastasis. The review is intended to highlight the chemistry of green tea, its antioxidant potential, its immunopotentiating properties and mode of action against various cancer cell lines that showed its potential as a chemopreventive agent against colon, skin, lung, prostate, and breast cancer.

“Isn’t it interesting that the intensity of the flu and cold season increases at the same time as the over consumption of food and alcohol during the holiday season?  Keep your immune system beefed up during these times by drinking the right amount of green tea on a daily basis.  Daily consumption of green tea can also have anti-inflammatory properties that are far-reaching.”  -Josh Smith

HOUSTON — Juanita Black has plenty to sing about. She turned 105 years old on Tuesday, KPRC Local 2 reported.

Her granddaughter Amy Black shouted in her ear, “How does it feel to be 105?”

Juanita answered, “OK.”

Other than being a little hard of hearing, Juanita’s in excellent health. She only takes three medications and has never consumed alcohol, smoked or driven a day in her life.

Amy Black said, “She walked everywhere. That might be why she’s so healthy.”

She then asked Juanita, “What’s your trick? Why are you 105?”

Juanita laughed, “Because I drink green tea.”

Amy nodded, “That’s right, people. Green tea.”
