Along with caffeine, which gives green tea its characteristic taste, bitterness, and stimulating effect, green tea is also rich in a group of chemicals, called catechin polyphenols (commonly known as tannins, which contribute to bitter taste and astringency). These catechin polyphenols include catechin, epicatechin, epicatechin gallate (ECG), epigallocatechin gallate (EGCG), and various proanthocyanidins. They are also known as flavonoids and are very powerful antioxidants. Flavonoids, together with some amino acids like thiamine, are responsible for the potent flavor of green tea.
Like gyokuro, matcha is shaded before plucking. The plucked and processed leaf is called tencha. This product is then ground into a fine powder, which is matcha. Because the tea powder is very perishable, matcha is usually sold in small quantities. It is typically rather expensive.[62] Matcha is the type of tea used in the Japanese tea ceremony. It is prepared by whisking the tea with hot water in a bowl, until the surface is frothy. If the water is too hot, the tea may become overly bitter.[64]

The antioxidants present in rooibos tea slow down the aging process and also boost the strength of the immune system. Researchers at Nelson Mandela Metropolitan University in South Africa found that the local herb helps slow down the degeneration of fat cells, thus inhibiting the formation of wrinkles. Antioxidants in the tea seek out free radicals that damage the skin, hair, bones, and other organ systems by making them vulnerable to diseases and degeneration.

I'm a mom of two boys and live in Larkspur, CA, but still call South Africa my home. I grew up (literally) with Rooibos Tea: a naturally caffeine free beverage that has been used by generations of South Africans for anything from a delicious anytime drink, to a soothing beverage to calm Baby's colic, to putting in the bath for dry & flaky skin. You name it, Rooibos is the cure. 
Simply stated, tea detoxes claim to rid your body of the toxins caused by a build-up of unhealthy foods, alcohol, and a number of other things your body doesn’t use to properly function. The teas are mixtures of various ingredients (green tea, matcha, oolong, goji berries, etc.), all with impressive health benefits, and the point is that the tea provides you with sustainable energy while subsequently eliminating toxins from your body. Most teas are to be consumed at least once a day, and some are accompanied by an additional colon cleanser.
Matcha is a type of green tea made by taking young tea leaves and grinding them into a bright green powder. The powder is then whisked with hot water. This is different from regular green tea, where the leaves are infused in water, then removed. Drinking brewed green tea “is a bit like boiling spinach, throwing away the spinach and just drinking the water,” says Louise Cheadle, co-author of The Book of Matcha and co-owner of the tea company teapigs. “You will get some of the nutrients, but you’re throwing away the best bit.” With matcha, you’re drinking the whole tea leaves.

Studies on green tea’s impact on cancer have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some clues that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's web site says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer."

Being a green tea, matcha does contain caffeine and in higher levels than other green teas. Because the entire leaf is used, matcha tea can contain nearly as much caffeine as a cup of coffee. However, caffeine release is believed to be slower because you are drinking the entire leaf. This slower release of caffeine reduces “caffeine jitters” that coffee or other teas can cause.
How many calories should I eat a day? A calorie is an amount of energy that a particular food provides. Consuming more calories than needed will result in weight gain, consuming too few will result in weight loss. How many calories a person should eat each day depends on a variety of factors, such as age, size, sex, activity levels, and general health. Read now 

I am not a tea drinker.....BUT this is the Best Tea I have ever had, ever! It does not need sugar or milk but I'm sure you could add these items if you preferred. I will definitely be getting more of this tea. Please, do not ever change this tea. It is perfect as it is now. Remember I am not a tea drinker but this tea has made me one. Thank you for Rooibos tea!
Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.

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.
Do you know what the term “cha” means, which is often found in the names of various qualities of green tea such as gyokurocha, sencha, bancha, matcha, and houjicha? It simply means “tea”, and tea is extremely popular all over India as “cha” (in Bengal & adjacent states) and “chai” in other areas. Just some fun facts for you to share with other tea lovers over your next cup of green tea!
Nine health benefits of turmeric tea Turmeric is a spice that contains curcumin, which seems to have anti-inflammatory and immune-boosting properties. In this article, we look at nine health benefits of turmeric tea. These include cancer prevention, protection against liver damage, and improved immune function. We also explain how to prepare turmeric tea. Read now
Japanese green teas have a thin, needle-like shape and a rich, dark green color. Unlike Chinese teas, most Japanese teas are produced by steaming rather than pan firing. This produces their characteristic color, and creates a sweeter, more grassy flavor. A mechanical rolling/drying process then dries the tea leaves into their final shape.[54] The liquor of steamed Japanese tea tends to be cloudy due to the higher quantity of dissolved solids.[56]

In conclusion, whilst there is a considerable body of evidence for green tea with some of it suggesting a positive effect, it is difficult to be definitive as to its health benefits.
Generally, lower-quality green teas are steeped hotter and longer while higher-quality teas are steeped cooler and shorter, but usually multiple times (2-3 typically). Higher-quality teas like gyokuro use more tea leaves and are steeped multiple times for short durations. Steeping too hot or too long results in the release of excessive amounts of tannins, leading to a bitter, astringent brew, regardless of initial quality. The brew’s taste is also affected by the steeping technique; two important ones are to warm the steeping container beforehand to prevent the tea from immediately cooling down, and to leave the tea leaf in the pot and gradually add more hot water during consumption.[citation needed]

And not all the science has been favorable to tea. A report in the March 1 edition of The New England Journal of Medicine looking at green tea consumption in humans, found no effect on stomach cancers once adjustments were made for other factors that could affect risk. Those other factors included sex, age, history of stomach ulcer, use of tobacco or alcohol, and other dietary habits.

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.[70] The restoration of the Korean way of tea began in the 1970s, around Dasolsa.[70] Commercial production of green tea in South Korea only began in the 1970s,.[71] By 2012 the industry was producing 20% as much tea as Taiwan and 3.5% as much as Japan.[72][73] 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.[74] Recently however, as the coffee market reached saturation point, South Korean tea production doubled during 2010‒2014,[75] as did tea imports during 2009-2015,[76] 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).
Today, an estimated 2.5 million tons of tea leaves are produced each year throughout the world, with 20 percent of that being green tea. Green tea didn’t become popular or widely distributed outside of Asia until about the early 1900s. China, other countries in Asia, countries in North Africa, the United States and Europe currently consume the most green tea worldwide. 

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.
Several population-based clinical studies have shown that both green and black teas may help protect against cancer. Early clinical studies suggest that the polyphenols in tea, especially green tea, may play an important role in the prevention of cancer. Researchers also believe that polyphenols help kill cancerous cells and stop them from growing.
Rooibos is being heavily hyped by producers and distributors as a new health beverage. Unlike true “tea,” it is caffeine-free and low in tannins. It contains minimal amounts of calcium, potassium, iron, zinc, magnesium and much less fluoride than found in real teas. Studies have shown that Rooibos does contain antioxidants and therefore might have some of the health benefits of green tea, but very little research has confirmed this. I found only 17 scientific studies of Rooibos compared to more than 1,000 on green tea. So far, none suggest that Rooibos is the health equivalent of green tea.
In China though, the term black tea or dark tea typically refers to a tea that we call Pu-erh in the United States. This tea is fermented anywhere between 2 weeks to two months and then aged for 2 months to 20+ years in order to create dark black leaves and a dark color to the brew. In this fermentation process the leaves are intentionally kept damp to encourage good microbes and bacteria to slowly oxidize and ferment the leaves. This is distinguished from red tea which typically only takes about 6-10 hours to oxidize. Pu-erh tea typically has a strong fermentation taste but high quality pu-erh should not taste overly earthy as this is a sign of low quality production techniques.
Grown under shade for three weeks prior to plucking, gyokuro is one of the most exclusive varieties of tea produced in Japan.[60] The shading technique imparts a sweeter flavor, and produces a particularly rich color thanks to the higher amounts of chlorophyll in the shaded leaf. Gyokuro tea is associated with the Uji region, the first tea-growing region in Japan. It is often made using smaller-leaf cultivars of the tea plant.[61]
