Tea & Health

Due to the specific processing and treatment of the tea leaves, Japanese green teas keep a considerable amount of substances which have an important and positive effect on a human organism. We call these substances antioxidants. Japanese green teas conserve antioxidants in tea leaves thanks to the process of steaming which is much less aggressive method of stopping tea leaf oxidation after the harvest, then the usual roasting of tea leaves common in Chinese or Indian teas. The absolute queen among green teas is undoubtebly the Japense whisked tea matcha. The matcha tea may have less catechines than another Japanese green tea sencha, but it contains more theanine and, above all, during its consummation we drink the tea leaves themselves ground into a delicate powder. Therefore, in one cup of whisked matcha tea we receive the biggest possible amount of all substances contained in tea including all catechines compared to any sort of infusion. For your better understanding of the positive effects of Japanese green tea, we would like to present to you the most important and beneficial substances that you may find in a Japanese steamed green tea with their benefits to our organism


With regard to the contribution to our health, the catechins are the most important antioxidants not only within antioxidants found in tea, but within all antioxidants ever discovered by humanity. A long-term consummation of catechins provides prevention of various cardiovascular diseases or carcinogenic tumours. Catechins support digestion and have a positive effect on old cells renewal. Through these beneficial effects, catechins may positively affect a human organism and prolong its viability. Catechins represents 20 % of substances forming a leaf of Japanese green tea.


Compared to catechins which affect our organism as a whole, theanins contribute to a general positive vitality through its considerable effect on our psyche. Theanin is a substance which stimulates the human brain by activating so called alpha waves and balancing the amount of dopamin and serotonin. That means that theanin serves as an effective  agent against stress. Thanks to its propreties, theanin calms down our minds, but through synthesis with caffeine doesn't cause physical or mental fatigue. Concerning the Japanese green teas, theanin is abundant mostly in gyokuro and matcha teas.


Kofein, v případě čaje někdy populárně označovaný jako tein, zvyšuje mozkovou aktivitu a tedy i naši pozornost. S ohledem na menší množství v čajových lístcích než například v kávě a díky vyvažujícím účinkům teaninů však působí na tělo pouze v pozitivním světle. Toto spoluovlivňování kofeinu/teinu a teaninů představuje největší přednost konzumace čaje v rozměru krátkodobých účinků, neboť společně zklidňují psychiku a zároveň zbystřují pozornost.
