“We Japanese drink green tea every day, and I think that this green tea cannot prevent every cancer, but it is the cheapest and most practical method of cancer prevention available to the general public.”

-Dr. Hirota Fujiki

History:  Chinese Emperor Shen Nung is credited with introducing green tea to the masses in 2737BC, and Traditional Chinese Medicine (TCM) has recommended green teaconsumption for good health since 1100BC.  In 1191, a Japanese priest named Esai took some C. sinensis seeds to Japan for medicinal purposes, later writing a book entitled “Maintaining Health by Drinking Green Tea.”

Varieties:  All teas originate from the C. sinensis plant. Harvest season, environmental conditions, plant age, processing, and storage are some of the factors that influence the wide variety of products available today.  Black tea is the most oxidized, followed by oolong, green, and lastly, white.

Scientific Research:  Green tea represents a perfect example of how science has come full circle, to support the medicinal wisdom of ancient folk tradition.

Studies supporting the health benefits of tea are abundant:

  • Anti-carcinogenic
  • Anti-thrombotic (thins the blood)
  • Cardio-protective
  • Anti-hypertensive (selectively lowers elevated blood pressure, without having an effect on normal blood pressure levels)
  • Lowers blood cholesterol
  • A 2013 lab study [1] shows great promise in the area of Alzheimer’s research, as well as other neurodegenerative diseases.  The EGCG component of green tea was shown to prevent the formation of beta-amyloid plaques associated with the disease, and to break up existing metal-containing aggregate structures that are known to cause misfolding of these proteins.  Further research is being conducted in this area.
  • Weight loss


How much do I need?

Research [2] shows that three to four 8 oz. cups of green tea per day is the ‘sweet spot’ for cancer prevention and heart disease.  According to research [[3]], one cup of green tea is equivalent to about 20-35mg of EGCG.

Black, green, or white?

White tea is the least processed, and has a milder flavor compared to green and black teas. One study [4] compared Exotica China white tea with Premium green tea brewed for 1-5 minutes, and found that Exotica white outperformed Premium green for its anti-cancer properties.   If you prefer to stick with green tea, consider sencha or matcha which have been shown to contain larger concentrations of active polyphenols.

Green and black teas contain L-theanine, which has been shown to help calm an anxious mind.  It also selectively lowers elevated blood pressure, while having no effect on normal blood pressure levels.   Green tea has also been studied [5] as an effective weight loss tool; helping to suppress appetite, and increase metabolism.  Both green and black teas have the potential to prevent cavities. Darker teas are also higher in theaflavins which have been shown to help lower blood cholesterol.


Lighter teas are higher in immune modulating catechins, while darker teas are richer in mood-enhancing, heart protective compounds:













Can I take a supplement?

I recommend experimenting with a variety of organic green and white tea varieties before resorting to a supplement.  Try as we might to isolate what we consider to be “only the good parts” of a plant in a lab, nature is wiser still.  Studies [6] confirm that the constituents in the whole plant work synergistically to optimize its beneficial effects.  You’ll also save a lot of money this way!

How can I avoid the concentrated amounts of aluminum and fluoride that have been making their way into tea leaves?

  • Choose a certified organic white or green tea.  Research has shown [7] that aged (darker) leaves are more likely to accumulate contaminants.
  • Know the provenance of your tea:
  • Organic teas from China- choose high mountain regions
  • Look for the Certified Organic seal (Oregon Tilth is one of the best certifications you can get):

Some of of my organic favorites include: Davidson’s Organic Teas, Art of TeaMitoku Macrobiotic, St. Dalfour, Starwest Botanicals, Eden Foods.

  • Avoid taking your tea with lemon, or foods rich in Vitamin C, which binds heavy metals.
