Health Benefits of Japanese Tea
The oldest book written about tea in Japan was Yosai's Kissa Yojoki in 1211.
This book was written as a medical journal and explained the effects of tea as medicine. Thus, even as far back as the 13th century, Japanese tea was considered to have health benefits. Many more recent studies have shown a detailed analysis of the health benefits of Japanese tea.
  • Antioxidant Effects

    The catechins, Vitamins C & E, and flavonols found in Japanese tea help limit oxidation within the body. Oxidation can lead to cancer, metabolic syndrome, and a variety of other sicknesses and bodily deterioration.

  • Preventing High Blood Pressure

    Catechins help control the movement of angiotensin converting enzymes known to cause high blood pressure.

  • Preventing Arteriosclerosis

    Catechins, especially EGCG, help control the oxidation of LDL cholesterol that can lead to arteriosclerosis.

  • Preventing Obesity

    Catechins help control the breakdown of glucose in the body and reduce the amount of fat built by glucose.

  • Preventing Bad Breath & Cavities

    Catechins, flavonols and chlorophyll are often used in chewing gum, and work to reduce odors. Additionally, catechins help to prevent cavities.

  • Antibacterial Effects

    Catechins work to kill bacteria like vibrio cholerae, staphylococcus aureus, and clostridium botulinum.

  • Antiviral Effects

    Catechins work to limit the propagation of viruses like the AIDS virus and influenza. Additionally, the saponin found in Japanese tea has antibacterial and antiviral properties that work against influenza.

  • Anti-allergy Effects

    The methylated catechins found in some types of Japanese tea help alleviate allergy symptoms to allergens such as pollen.

  • Combating Dementia

    Research in Japan has shown that catechins are effective against brain tissue contraction, help combat reductions in cognitive ability and memory, and suppress DNA damage caused by the oxidation of brain cells. US research has also shown catechins to be effective in slowing the progression of Alzheimer’s in mice with the disease.

  • Curbing Carcinogens

    A study conducted in Japan found that Japanese tea may have a preventive effect on some cancers of the stomach and prostate.
