            Polyphenols are a class of phytochemicals found in high concentrations in green tea, and have been   associated  with                              heart disease and cancer prevention. The slight astringent, bitter taste of green tea is attributed to polyphenols.

                 Lipid-soluble tea polyphenols (LTPs) are products of modified GTPs with ester linkage with fatty acids. LTPs are lipophilic                         and expected to provide improved absorption and utilization in the body compared with water-soluble polyphenols.

      2.  EGCG:

           Epigallocatechin gallate, also known as epigallocatechin-3-gallate, is the ester of epigallocatechin and gallic acid, and is a type of             catechin. EGCG – the most abundant catechin in tea – is a polyphenol under basic research for its potential to affect human                   health and disease.

      3.  Natural L-Theanine:

           Theanine - An amino acid that produces tranquilizing effects in the brain, theanine is a unique amino acid found in the leaves                 sencha. Theanine is quite different from the polyphenol and catechin antioxidants for which green tea is typically consumed.                 Through the natural production of polyphenols, the tea plant converts theanine into catechins. This means that tea leaves                       harvested during one part of the growing season may be high in catechins (good for antioxidant benefits), while leaves                             harvested during another time of year may be higher in theanine (good for anti-stress and cortisol-controlling effects).

        Ⅵ.  What's Green Tea

Green tea is made from the Camellia sinensis plant. The dried leaves and leaf buds of Camellia sinensis are used to produce various types of teas. Green tea is prepared by steaming and pan-frying these leaves and then drying them. Other teas such as black tea and oolong tea involve processes in which the leaves are fermented (black tea) or partially fermented (oolong tea). People commonly drink green tea as a beverage.

As a prescription, green tea is used for genital warts. As a drink or supplement, it is sometimes used for high levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia) and high blood pressure, to prevent heart disease, and to prevent cancer of the lining of the uterus (endometrial cancer) and ovarian cancer. It is also used for many other conditions, but there is no good scientific evidence to support these other uses.


        Ⅶ.  Benefits and Dosage of Green Tea Extract 

Likely Effective for

  • Genital warts. A specific green tea extract ointment (Veregen, Bradley Pharmaceuticals; Polyphenon E ointment 15%, MediGene AG) is available as a prescription product for treating genital warts. Applying the ointment for 10-16 weeks seems to clear these types of warts in 24% to 60% of patients.

Possibly Effective for

  • Heart disease. Population studies suggest that drinking green tea is linked to a reduced risk of clogged arteries. The link seems to be stronger in men than women.

  • Cancer of the lining of the uterus (endometrial cancer). Population studies suggest that drinking green tea is linked to a reduced risk of developing endometrial cancer.

  • High levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia). People who consume higher amounts of green tea seem to have lower levels of total cholesterol, low-density lipoprotein (LDL or "bad") cholesterol, and blood fats called triglycerides. They also seem to have higher levels of high-density lipoprotein (HDL or "good") cholesterol. Consuming green tea or taking green tea extract daily for up to 24 weeks may reduce total cholesterol and LDL cholesterol. Early research also suggests that green tea extract might reduce damage to vein and artery walls in people with high cholesterol.

  • High blood pressure. Drinking green tea might reduce the risk of developing high blood pressure. It might also slightly lower blood pressure in people with high blood pressure. But not all research agrees.

  • Ovarian cancer. Women who regularly drink tea, including green or black tea, appear to have a lower risk of developing ovarian cancer. But green tea does not seem to prevent people who have already had ovarian cancer from getting ovarian cancer again.

  • Parkinson disease. Some research shows that drinking caffeinated beverages can reduce the risk of Parkinson disease. Drinking one to four cups daily seems to provide the most protection against developing Parkinson disease.


The following doses have been studied in scientific research:


  • For high levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia): Green tea or green tea extracts containing 150 to 2500 mg catechins, taken in single or 2 divided doses daily for up to 24 weeks, has been used.

  • For abnormal cells on the surface of the cervix (cervical dysplasia): 200 mg of green tea extract, taken by mouth daily along with a green tea ointment applied twice weekly for 8-12 weeks, has been used.

  • For high blood pressure: A green tea drink, made by boiling a 3 gram tea bag with 150 mL water, has been used three times daily about 2 hours after each meal for 4 weeks. Also, 379 mg of a specific product containing green tea extract (Olimp Labs, Debica, Poland), taken daily with the morning meal for 3 months, has been used.

  • For low blood pressure: 400 mL of green tea taken before lunch has been used.

  • For white patches inside the mouth that are usually caused by smoking (oral leukoplakia): 3 grams of mixed green tea taken by mouth and applied to the skin for 6 months has been used.


  • For genital warts: A specific green tea extract ointment (Veregen, Bradley Pharmaceuticals; Polyphenon E ointment 15%, MediGene AG) applied three times daily to warts for up to 16 weeks, has been used. This product is FDA-approved for treating this condition.

  • For abnormal cells on the surface of the cervix (cervical dysplasia): A green tea ointment has been used alone twice weekly, or in combination with 200 mg of green tea extract taken by mouth daily for 8-12 weeks.

  • For white patches inside the mouth that are usually caused by smoking (oral leukoplakia): 3 grams of mixed green tea taken by mouth and applied to the skin for 6 months has been used.


        Ⅷ.  What are the side effects of taking Green Tea extract

When taken by mouth: Drinking green tea is LIKELY SAFE for most healthy adults when consumed in moderate amounts (about 8 cups per day).

Green tea extract is POSSIBLY SAFE for most people when taken by mouth for up to 2 years or when used as a mouthwash, short-term. In some people, green tea extract can cause stomach upset and constipation. Green tea extracts have been reported to cause liver and kidney problems in rare cases.

Drinking green tea is POSSIBLY UNSAFE when consumed for a long time or in high doses (more than 8 cups per day). Drinking large amounts of green tea might cause side effects due to the caffeine content. These side effects can range from mild to serious and include headache, nervousness, sleep problems, vomiting, diarrhea, irritability, irregular heartbeat, tremor, heartburn, dizziness, ringing in the ears, convulsions, and confusion. Green tea also contains a chemical that has been linked with liver injury when used in high doses. In order to reduce the risk for liver injury, take green tea extract with food.

When applied to the skin: Green tea extract is LIKELY SAFE when a specific, FDA-approved ointment (Veregen, Bradley Pharmaceuticals) is applied to the skin, short-term. Green tea is POSSIBLY SAFE when other green tea products are applied to the skin, short-term.

Special Precautions & Warnings:

Children: Green tea is POSSIBLY SAFE for children when taken by mouth in amounts commonly found in foods and beverages, or when used for gargling three times daily for up to 90 days. Not enough is known about safety of green tea extract when taken by mouth in children. However, cases of liver damage have been reported for adults who used green tea extract. Therefore, some experts recommend that children under the age of 18 years old do not take green tea extract.

Pregnancy and breast-feeding: If you are pregnant or breast-feeding, drinking green tea is POSSIBLY SAFE in amounts of 6 cups per day or less. This amount of green tea provides about 300 mg of caffeine. Drinking more than this amount during pregnancy is POSSIBLY UNSAFE and has been linked to an increased risk of miscarriage and other negative effects. Also, green tea might increase the risk of birth defects associated with folic acid deficiency.

In women who are nursing, caffeine passes into breast milk and can affect a nursing infant. Nursing mothers should closely monitor caffeine intake to make sure it is on the low side (2-3 cups per day). High intake of caffeine by nursing mothers can cause sleep problems, irritability, and increased bowel activity in breast-fed infants.

"Tired blood" (anemia): Drinking green tea may make anemia worse.

Anxiety disorders: The caffeine in green tea might make anxiety worse.

Bleeding disorders: Caffeine in green tea might increase the risk of bleeding. Don't drink green tea if you have a bleeding disorder.

Heart conditions: Caffeine in green tea might cause irregular heartbeat.

Diabetes: Caffeine in green tea might affect blood sugar control. If you drink green tea and have diabetes, monitor your blood sugar carefully.

Diarrhea: Green tea contains caffeine. The caffeine in green tea, especially when taken in large amounts, can worsen diarrhea.

Glaucoma: Drinking green tea increases pressure inside the eye. The increase occurs within 30 minutes and lasts for at least 90 minutes.

High blood pressure: The caffeine in green tea might increase blood pressure in people with high blood pressure. However, this effect might be less in people who consume caffeine from green tea or other sources regularly.

Irritable bowel syndrome (IBS): Green tea contains caffeine. The caffeine in green tea, especially when taken in large amounts, might worsen the diarrhea some people have with IBS.

Liver disease: Green tea extract supplements have been linked to rare cases of liver damage. Green tea extracts might make liver disease worse. Talk to your doctor before taking a green tea extract. Tell your doctor if you have signs of liver damage such as yellowing skin, dark urine, or abdominal pain. Keep in mind that drinking green tea as a beverage in normal amounts is still probably safe.

Weak bones (osteoporosis): Drinking green tea can increase the amount of calcium that is flushed out in the urine. This might weaken bones. If you have osteoporosis, don't drink more than 6 cups of green tea per day. Taking calcium supplements may help make up for calcium that is lost. If you are generally healthy and getting enough calcium from your food or supplements, taking up to 400 mg of caffeine (about 8 cups of green tea) per day doesn't seem to increase the risk of getting osteoporosis.
