It depends not only on the processing method the tea producers use, but also on the cultivation practices the tea growers use. What time of year is the tea plucked? How is the plant pruned? What parts of the plant are plucked? Are the plants treated with chemicals or are they organically grown? What kind of heat is applied to the tea leaves to stop oxidation? How are the tea leaves shaped, rolled and dried? Are the leaves left whole or cut in smaller pieces?
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.
Flavan-3-ols, the type of flavonoids found in green tea and other teas, provide many of the anti-aging effects of green tea. Catechins in various types of teas are the polyphenols that seem to have the most potent antioxidant effects, according to Natural Standard, the leading and most respected reviewer of herbal compounds. Specific flavan-3-ols found in green tea include monomers (catechins) called:
• 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.

But ConsumerLab.com’s testing has found that even if lead is found in the leaves used in green tea bags, it doesn’t appear to be absorbed into the water. Cooperman says his team was concerned about lead content in matcha, because people consume the ground green tea leaves directly rather than in bags. However, their testing showed that among the six popular matcha brands they tested—DoMatcha, Encha Organic Matcha, Rishi Teahouse Matcha, Teavana Imperial Matcha, Kirkland Signature Green Tea and The Republic of Tea Double Green Matcha Tea—the powders were not contaminated by lead or other metals, and also did not contain pesticides. As of now, Cooperman says he doesn’t believe lead exposure is a risk in the matcha currently sold in the United States.
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.

Sometimes given to babies suffering from colic, rooibos is known for anti-spasmodic activity. A growing body of evidence suggests that the health benefits of rooibos may be quite broad, including evidence that the antioxidants in the tea may reduce the risk of heart disease, and may inhibit some parameters of aging. Rooibos even shows use as a cosmetic ingredient for soothing, protecting and repairing skin.
That being said, this is not some magical product. It doesn't dissolve any different than other premium matcha, it doesn't have a considerably higher level of antioxidants or the like and challenge any product that claims so to put their claims to the test via hard data. What you get here is clean tasting, extremely flexible, and organic matcha. The size of the bag is perfect.
Day 1: So you’re supposed to drink your tea first thing in the morning (or before a workout), but I didn’t receive my package until after arriving home for the day (in the early evening). Since I am a slave to my own desire for instant gratification, I said “Screw the rules!” and made my first cup right then and there. Immediate observation: It’s actually pretty delicious. I don’t consider myself a tea connoisseur by any means, so I was pleasantly surprised. I didn’t think it needed the recommended addition of honey.
One-1/2 teaspoon serving of matcha, no more than once daily, is certainly a valuable addition to any diet, says Zeitlin. Like with another substance currently having a moment, turmeric, you can get your dose by eating or drinking it, though Zeitlin says drinking it as a tea, how it was initially intended, provides all the benefits without the added calories.
Research also shows that green tea lowers total cholesterol, improving the overall cholesterol profile. One population-based clinical study found that men who drink green tea are more likely to have lower total cholesterol than those who do not drink green tea. Other clinical studies that look at populations of people indicate that the antioxidant properties of green tea may help prevent atherosclerosis, particularly coronary artery disease. The benefits also seem to extend to preventing stroke, reducing high blood pressure, and inhibiting the formation of blood clots. Much of the effect may also be due to the ability of green tea to help lower blood sugar and insulin levels.
Tea culture of Korea was actively suppressed by the Japanese during the Japanese forced occupation period (1910‒1945), and the subsequent Korean War (1950‒1953) made it even harder for the Korean tea tradition to survive. The restoration of the Korean way of tea began in the 1970s, around Dasolsa. Commercial production of green tea in South Korea only began in the 1970s,. By 2012 the industry was producing 20% as much tea as Taiwan and 3.5% as much as Japan. Green tea is not as popular as coffee or other types of Korean teas in modern South Korea. The annual consumption per capita of green tea in South Korea in 2016 was 0.16 kg (0.35 lb), compared to 3.9 kg (8.6 lb) coffee. Recently however, as the coffee market reached saturation point, South Korean tea production doubled during 2010‒2014, as did tea imports during 2009-2015, despite very high tariff rate (513.6% for green tea, compared to 40% for black tea, 8% for processed/roasted coffee, and 2% for raw coffee beans).
