~ TeaForHealth: Specifications For Our Tea ~

Commercially available green teas vary widely in antioxidant potency, scientifically expressed in EGCG levels, and may contain various pesticides. Dr. Lee's TeaForHealth® green tea, however, is certified to contain a minimum 7.10% EGCG or higher in dry weight. In collaboration with a tea research institute in China, these standards are designed to maximize the health benefits of green tea.

Total tea catechins: 10% dry weight minimum
EGCG: (-)-epigallocatechin gallate: 7% dry weight minimum #
Heavy metals: Codex* and U.S. Environmental Protection Agency limits
Pesticides: Codex* and U.S. Environmental Protection Agency limits
Fluoride: Meets FDA limits for bottled beverages*

# This specification meets the standard for typical green tea defined by the National Cancer Institute if a customary 1:100 w/v dry tea leaf-to-water ratio is used to brew tea drinks. For comparison, most green teas on the markets contain 2-4% EGCG or lower in dry weight. Refer to the Tea Library for more information.
* Codex: Codex Alimentarius Commission of Food and Agriculture Organization - FAO & World Health Organization - WHO of the United Nations.
Sample analyses of our teas for lead, pesticides and fluoride are posted on the FDA Dockets Management website.

TeaForHealth® is only harvested in the spring and the fall seasons when the growth of the tea tree is slower. This allows for increased concentration of the active ingredients in the tea leaves. The tea is selected only from plantations that do not use chemically synthetic pesticides or fertilizers, and certified to be organically cultivated by the Organic Tea Research and Development Center of China. The fresh tea leaves are processed immediately upon harvest and are packaged in vacuum with nitrogen flushing to prevent oxidation and to delay degradation during storage.

The total concentration of green tea catechins (GTCs) is about 15%, and the EGCG content is about 9-11% in dry weight when our teas are freshly packaged. While all teas eventually decrease in antioxidant activity during storage, Dr. Lee's TeaForHealth® green teas are sealed in vacuum with nitrogen flushing, which greatly slows the degradation process. The GTC and EGCG contents are at least 10% and 7.10%, respectively. Pesticide and heavy metal contaminant residues and the fluoride level in Dr. Lee’s TeaForHealth® are non-detectable or well below the limits set by the U.S. Environmental Protection Agency, Pharmacopoeia for Herbal Medicines and the FDA, respectively. Certificates of analysis of each lot of green tea issued by independent laboratories are kept on file as quality assurance to consumers.

~ 710EGCG® Green Tea ~

In ancient China, tea was used as both food and as a way to maintain good health. Tea was originally described as “bitter sprouts” in the old language. All teas were good for health purpose, first cultivated by the Taoists functioning as physicians in the tea gardens of their monasteries. The terms of green tea, black tea and oolong tea did not exist in the ancient Chinese language because all teas were green tea by today’s definition.

Natural green tea drink has an astringent taste, “bitter” to those not used to it. The taste of the green tea harvested from the same plantation is influenced by weather, which determines the ratios of the various kinds of chemicals, such as the polyphenols, or cathechins, in the tea leaves. Humans cannot control the weather. Therefore, no one can really fix the taste of green tea from year to year, like one can for the taste of certain brand-named black teas and woolong teas whose tastes are largely determined by a manufacturing process, called oxidation or “fermentation”, which can be controlled. In chemical terms, dried young leaves freshly harvested from the tea trees cultivated as they were 2,000 years ago should have the following qualities.

Total tea catechins: 10% dry weight minimum
EGCG: (-)-epigallocatechin gallate: 7.1% dry weight minimum (see note)
Heavy metals: Lead residues not to exceed 5 ppm.*
Pesticides: No detectable Organochlorines, Organophosphates, Organonitrogens and Carbamates by a certified laboratory in the USA.*
Fluoride: Not to exceed of 240 ppm fluoride. *

Note: This specification meets the standard for typical green tea defined by the US National Cancer Institute for cancer research if a customary 1:100 w/v dry tea leaf-to-water ratio is used to brew tea drinks. [Reference: NCI, DCPC, Chemoprevention Branch and Agent Development Committee, Clinical development plan: tea extracts green tea polyphenols epigallocatechin gallate. J Cell Biochemistry 1996;26S:236-257.]

* Young tea leaves harvested freshly 2,000 years ago were all good for health purpose because the EGCG level was always high and the fluoride low in young leaves; and no leaded gasoline or chemical insecticides were in use on earth then.

~ Where Is Our Tea From? ~

Our tea comes from a Chinese tea plantation which is located in a frost-free misty hillside away from pesticide-sprayed agricultural crops, industrial pollutants, and automobile discharges. Growth conditions favor the maximum production of the natural health ingredients in the tea leaves. To preserve the health ingredients, the tea leaves must be processed at the plantation. The major steps are to heat-inactivate the polyphenol oxidase without destroying the EGCG in the tea leaves, and package the tea leaves under vacuum with nitrogen refills.

  • Standard Grade Tea : The 710EGCG® standard grade green tea leaves are harvested by mechanical cutting blades, and processed in a machine. These select tender tea leaves meet all the specifications, but the sizes of the leaves vary.

  • Deluxe Grade Tea : The 710EGCG® deluxe grade green tea leaves are harvested by hands. Only the tender buds and the adjacent two young leaves at the tip of a tea plant branch can be plucked for hand processing in order to preserve the natural shape of the leaves. In this manner, much of the fragrant aroma of the young tea leaves is also retained. Many tea drinkers prefer deluxe tea. But its supplies are limited. The 710EGCG® specifications for the standard and deluxe green tea are identical.

~ Our Patented Mug ~

In modern medical research, the scientists found that the green tea for the laboratory mice must be prepared in distilled water under nitrogen in an Erlenmeyer glass flask to prevent oxidation. Only under these brewing conditions, the beneficial effects of green tea can be reproduced in animal experiments. The ancient Chinese scientists learned all these through human observations. They invented in the Tang dynasty porcelain, a non-metallic material, to make tea sets, which we now call “chinaware”. In the Ming dynasty, they also invented a tea-brewing bowl called Zhong with a sinking lid to exclude the atmospheric air to make tea. The Taoist herbalists used to save the melted snow, rain water and the morning dew water collected from the lotus leaves to make tea. Dr. Lee has combined all these ancient and modern observations into a patented oxygen exclusion lead-free tea set for the convenience of tea brewing in our daily life. This tea steeper is covered by US patents #6821541 and #D494417.
