Tea and Cancer Prevention

The following report is from the National cancer Institute.

You see, the tea for daily drinking & for healing is totally different when mixture & the compound is concern.

The use of Herbals Tea to heal would be dependant upon the organ of which part of the body is having cancer. there is no one single herbal tea can actually used to heal cancer.

According to the "I-Medicine Sutra", Like Tien Chi Gingen; Barley, Ling Ci Fungus, Milktwister; Huan Lian..etc. all have the detoxine & Antioxidants to heal cancer. But one must consult the expert before drinking it for healing.

One observations is that for these Chinese Herbs for healing , it work perfect in the initial stage of the illness only. If the later stage, my advise is to go for the western medical treatment, before it is too late.


Tea and Cancer Prevention

Key Points


* The antioxidants found in tea--called catechins--may selectively inhibit the growth of cancer (see Question 1).

* In laboratory studies using animals, catechins scavenged oxidants before cell damage occurred, reduced the number and size of tumors, and inhibited the growth of cancer cells (see Question 3).

* However, human studies have proven more contradictory, perhaps due to such factors as variances in diet, environments, and populations (see Question 4).

* NCI researchers are investigating the therapeutic and preventive use of tea catechins against a variety of cancers (see Question 5).


Tea drinking is an ancient tradition dating back 5,000 years in China and India. Long regarded in those cultures as an aid to good health, researchers now are studying tea for possible use in the prevention and treatment of a variety of cancers. Investigators are especially interested in the antioxidants-called catechins-found in tea. Despite promising early research in the laboratory, however, studies involving humans so far have been inconclusive.

1. What are antioxidants?

The human body constantly produces unstable molecules called oxidants, also commonly referred to as free radicals. To become stable, oxidants steal electrons from other molecules and, in the process, damage cell proteins and genetic material. This damage may leave the cell vulnerable to cancer. Antioxidants are substances that allow the human body to scavenge and seize oxidants. Like other antioxidants, the catechins found in tea selectively inhibit specific enzyme activities that lead to cancer. They may also target and repair DNA aberrations caused by oxidants (1).

2. What is the level of antioxidants found in tea?

All varieties of tea come from the leaves of a single evergreen plant, Camellia sinensis. All tea leaves are picked, rolled, dried, and heated. With the additional process of allowing the leaves to ferment and oxidize, black tea is produced. Possibly because it is less processed, green tea contains higher levels of antioxidants than black tea.

Although tea is consumed in a variety of ways and varies in its chemical makeup, one study showed steeping either green or black tea for about five minutes released over 80 percent of its catechins. Instant iced tea, on the other hand, contains negligible amounts of catechins (1).Read More...
