Liver problems have been reported in a small number of people who took concentrated green tea extracts. Although the evidence that the green tea products caused the liver problems is not conclusive, experts suggest that concentrated green tea extracts be taken with food and that people discontinue use and consult a health care provider if they have a liver disorder or develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice.

Because matcha is prone to clumping (that’s why you’ll see instructions to sift it before whisking in the water or milk), you’ll want to take the same precaution in your baking experiments: Saffitz suggests combining the matcha with other dry ingredients like sugar or flour to avoid bitter lumps in your dough or batter. And use it sparingly, she suggests: Even a few teaspoons can create an intense flavor (and color).

Green tea has slightly more antioxidants compared to black tea, although both are still great sources. The ORAC value (antioxidant content) of brewed black tea is 1,128 while green tea is slightly higher at 1,253. Black tea and green tea both contain antioxidants, including polyphenols. Some research shows that green tea contains more than four times the catechins that black tea does. Both types can contribute antioxidants to your diet and have been shown to have antiviral, anti-inflammatory, detoxifying and immune-stimulating effects.

It is used in castella, manjū, and monaka; as a topping for shaved ice (kakigōri); mixed with milk and sugar as a drink; and mixed with salt and used to flavour tempura in a mixture known as matcha-jio. It is also used as flavouring in many Western-style chocolates, candy, and desserts, such as cakes and pastries (including Swiss rolls and cheesecake), cookies, pudding, mousse, and green tea ice cream. Matcha frozen yogurt is sold in shops and can be made at home using Greek yogurt. The Japanese snack Pocky has a matcha-flavoured version. Matcha may also be mixed into other forms of tea. For example, it is added to genmaicha to form what is called matcha-iri genmaicha (literally, roasted brown rice and green tea with added matcha).
Green tea is processed using either artisanal or modern methods. Sun-drying, basket or charcoal firing, or pan-firing are common artisanal methods. Oven-drying, tumbling, or steaming are common modern methods.[32] Processed green teas, known as aracha, are stored under low humidity refrigeration in 30- or 60-kg paper bags at 0–5 °C (32–41 °F). This aracha has yet to be refined at this stage, with a final firing taking place before blending, selection and packaging take place. The leaves in this state will be re-fired throughout the year as they are needed, giving the green teas a longer shelf-life and better flavor. The first flush tea of May will readily store in this fashion until the next year's harvest. After this re-drying process, each crude tea will be sifted and graded according to size. Finally, each lot will be blended according to the blending order by the tasters and packed for sale.[33]
Matcha contains a healthy form of caffeine; not to be mistaken with the one present in regular coffee. This unique form of caffeine known as theophylline sustains the energy levels without any adverse effects. The slow release of energy due to theophylline helps in supporting the functionality of adrenal glands. It also maintains optimum hormonal levels.

• One Chinese study found that men who drank more than three cups of tea a day reduced their risk of prostate cancer by 70 percent. In another study funded by the National Institute of Health, 79 men with prostate cancer were told to either drink 6 cups of green tea a day or 6 cups of water. After 3 to 8 weeks, the levels of prostate-specific antigen, a protein that may indicate cancer, were lower in the men who drank green tea than those who drank water. An indicator of inflammation, nuclear factor-kappaB, linked to cancer growth, was also lower in the men who drank the green tea.


Tea plants that are specifically grown and used to make matcha are also typically shaded for two weeks to increase chlorophyll levels before the leaves are picked, further boosting concentration of healthy compounds. Matcha green tea tends to be more expensive than buying tea leaves for steeping, but a little goes a long way. Matcha is usually available in powder form and is a good choice for adding green tea’s taste and the benefits of green tea to recipes like smoothies, baked goods or ice cream.
Matcha, like other green teas, contains a class of antioxidants called catechins. Matcha is high in a catechin called EGCG (epigallocatechin gallate), which is believed to have cancer-fighting effects on the body. Studies have linked green tea to a variety of health benefits, like helping to prevent heart disease, type 2 diabetes and cancer, and even encouraging weight loss. However, it’s important to note that much of this research isn’t from clinical trials that show green tea causes a benefit. Instead, it’s largely from population-based studies, where researchers look at groups of people who drink green tea and compare their health outcomes to groups that don’t drink it. Studies have shown associations between tea and better health, but causation is not yet proven. Matcha is even less studied than brewed green tea.
Already nearly calorie free, matcha is a great addition to a weight loss program by tackling the problem from both sides. It boosts metabolism and burns fat. One recent study even suggested that matcha may help burn calories by four times. At the same time, matcha does not put any stress on the body. It doesn’t raise blood pressure or heart rate, making it a safe alternative to questionable quick fixes or pharmaceuticals ridden with side effects.
In response, the governor of Shizuoka Prefecture, Heita Kawakatsu, stated: "there is absolutely no problem when they [people] drink them because it will be diluted to about 10 becquerels per kilogram when they steep them even if the leaves have 1,000 becquerels per kilogram;" a statement backed by tests done in Shizuoka.[35] Japanese Minister for Consumer Affairs and Food Safety Renhō stated on 3 June 2011 that "there are cases in which aracha [whole leaves of Japanese green tea] are sold as furikake [condiments sprinkled on rice] and so on and they are eaten as they are, therefore we think that it is important to inspect tea leaves including aracha from the viewpoint of consumers' safety."[36]
Most importantly, EGCg and other catechins counteract the effects of free radicals from the likes of pollution, UV rays, radiation, and chemicals, which can lead to cell and DNA damage. Since over 60% of the catechins in matcha are actually EGCg, a daily matcha regimen can help restore and preserve the body’s integral well-being and balance. Read more on our Change The Odds Page.
Green tea, however, is considered to have originated in China. It is said that even today the word “tea” in China refers only to green tea, not to the general category of tea as it does in the West. China’s Yunnan province is considered to be the original home of the Camellia sinensis plant species. In fact, 260 of the world’s 380+ varieties of tea can be found in Yunnan.
