KORAKUNDAH JASMINE GREEN TEA
100% ORGANIC CERTIFIED GREEN TEA
A native of the rainy forests of Southeast Asia, the tea plant is cultivated in Burma, China, India, Japan, Turkey, Pakistan, Malawi, Argentina, Georgia, Sri Lanka, and Africa. The evergreen leaves are limp and downy when young, thick and rounded when mature. In the wild, this small tree grows many small branches. Cultivated tea plants are regularly pruned and kept to a height of about five feet (150 centimeters) to make harvesting easy. Only the leaf buds and young leaves are harvested, by hand, to make tea.
Green tea and black tea (the more familiar beverage type of tea) come from the same plant, but green tea is less processed so more of the original plant substances survive in this herb. Green tea contains high levels of substances called polyphenols, which are known to have strong antioxidant, anticarcinogenic, antitumorigenic, and antibiotic properties.
EVIDENCE OF BENEFIT
Green tea is both a stimulant and an antioxidant with a diversity of healing applications. The polyphenols in green tea are potent antioxidants. Researchers have found that one of the polyphenols, designated epigallocatechin gallate (EGCG), is over 200 times more powerful than the renowned antioxidant vitamin E in neutralizing free radicals. Also, green tea increases energy, which may make it useful as part of a weight-loss program.
Benefits of green tea for specific health conditions include the following:
• Asthma. Theophylline, a chemical found in both green and black tea, is extracted from the leaf of the tea plant. Theophylline relaxes the smooth muscles supporting the bronchial tubes, reducing the severity of asthma and bronchitis. Drinking either green or black tea provides theophylline in doses large enough to affect asthma.
• Atherosclerosis and high cholesterol. Green tea lowers blood cholesterol without side effects and lowers blood pressure using a mechanism employed by modern drugs classified as angiotensin--converting enzyme (ACE) inhibitors. More important, clinical studies have shown that green tea slows the oxidation of low-density lipoprotein (LDL, or "bad") cholesterol into forms that can cause atherosclerotic plaques, although researchers describe this effect as mild. Black tea has a similar effect.
• Breast cancer, endometriosis, fibroeystic breasts, and ovarian, cancer. The polyphenols in green tea occupy many of the sites on the exteriors of cells that otherwise would receive estrogen. This keeps the cells from receiving estrogen, reducing the effects of estrogen on the body. This stops estrogen from stimulating growth of cells in breast, ovarian, and uterine cancer.
• Cancer. A number of animal studies have shown that the polyphenols in green tea may offer significant protection against cancers of the pancreas, colon, stomach, lung, and small intestine. It is believed that they do this by blocking the formation of cancer-causing compounds such as nitroamines, suppressing the activation of carcinogens, and detoxifying cancer-causing agents. Other compounds in green tea provide protection from the effects of repeated exposure to gamma radiation, preventing the development of thyroid cancer caused by radiation treatment. Green tea catechins prevent the cancer therapy drug mitomycin (Mutamycin) from causing changes in the bone marrow that lead to leukopenia, the dangerously low white blood cell counts that often complicate cancer treatment.
• Cirrhosis of the liver and liver cancer. Researchers have found that, on average, individuals who consumed large amounts of green tea have lower levels of certain liver enzymes in their blood, which suggests that green tea may help prevent liver damage. Up to 30 percent of the weight of a green tea leaf consists of potent antioxidant catechins. These compounds help to protect the linings of red blood cells and liver cells from damage from oxygen free radicals released by toxins and caused by imbalances of micronutrients in the bloodstream.
• Colorectal cancer and food poisoning. Green tea catechins kill many types of foodborne bacteria, especially Clostridium bacteria, which are associated with colon cancer. Laboratory studies with animals have found that the regular consumption of green tea catechins prevents the growth of colorectal tumors.
• Diabetes. In people with diabetes, green tea extracts suppress the formation of the "sticky" blood proteins called glycosylation products, which can cause small blood vessels to thicken and leak. Green tea also keeps sugar out of the bloodstream in the first place by inhibiting the enzymes in the mouth and intestines that break down carbohydrates into simple sugars.
• Ear infections, eczema, and periodontal disease. Green tea catechins prevent Streptococcus mutans from forming dental plaque. (This may explain why early Asians cleaned their teeth with whisks of green tea leaves-before the invention of toothpaste.) Green tea's antimicrobial effects make it useful for other conditions as well, such as ear infections and eczema.
• Herpesvirus infection. Green tea, applied as a compress, increases the effectiveness of topical interferon treatment of herpes. The green tea compress is applied first. Then the skin is allowed to dry without washing before the interferon treatment.
• Influenza. Green tea extract helps ward off the flu by preventing influenza A viruses from replicating. This effect holds even when the extract is given at 100 times the concentration of amantadine (Symmetrel), one of only a few other effective treatments for flu. Green tea extracts also protect against infection with the influenza B virus, against which amantadine is not effective and for which zanamivir (Relenza) is only partially effective.
• Wrinkles. Green tea protects the skin from the effects of harmful free radicals that can lead to wrinkling.
CONSIDERATIONS FOR USE
Studies suggest that 3 cups (an amount containing the equivalent of 240 to 320 milligrams of polyphenols) of green tea daily provide protection against cancer. However, other research suggests that as much as 10 cups per day is necessary to obtain noticeable benefits. Tablets and capsules containing standardized extracts of polyphenols, particularly EGCG, some providing 97 percent polyphenol content (equivalent to drinking 4 cups of tea) are available. Green tea also can be used in cream form or made into compresses.
Some herbal formulas, particularly those intended for use at the early stages of cold and flu, act at a molecular level by producing free radicals. Green tea stops the reactions that form free radicals. You can take green tea to avoid coming down with colds or flu, but if the flu does strike, discontinue green tea use until symptoms subside.
You should not take green tea within one hour of taking herbal teas or patent (over-the-counter) medicines. This avoids diluting the decoction in the stomach or interfering with the medication. This is especially important if you are taking codeine, colchicine, or ephedrine, which may become insoluble in the presence of tannins from green or black tea. Finally, you should not drink green tea if you are using ginseng regularly. Green tea can reduce the effectiveness of ginseng. Black tea is not known to have this effect. If you are pregnant or nursing, you should use only limited amounts of green tea.
People who are taking monoamine oxidase (MAO) inhibitors or the blood thinner warfarin (Coumadin) should not use green tea medicinally. Green tea contains vitamin K, which directly counteracts the blood-thinning action of warfarin. Certain prescription medications increase the stimulant effects of caffeine found in green tea. These include the ulcer drug cimetidine (Tagamet) and antibiotics such as ciprofloxacin (Cipro), enoxacin (Penetrex), and norfloxacin (Noroxin). Combining green tea (or any other beverage that contains caffeine) with these medications could result in overstimulation and insomnia.
