An animal study published in 2009 in “Phytomedicine” found that green rooibos tea helped regulate glucose metabolism, preventing increases in fasting blood glucose levels during the course of the five-week study. This effect is a result of aspalathin, a compound found in green rooibos. Poor glucose tolerance and high fasting glucose levels are signs of type-2 diabetes and are common in obesity. The study suggests rooibos tea may help keep blood glucose levels in check, preventing sharp spikes and falls that can trigger symptoms of hunger and possibly leading to lower calorie consumption.
Polyphenols found in green tea include epigallocatechin gallate (EGCG), epicatechin gallate, epicatechins and flavanols,[1] which are under laboratory research for their potential effects in vivo.[4] Other components include three kinds of flavonoids, known as kaempferol, quercetin, and myricetin.[5] Although the mean content of flavonoids and catechins in a cup of green tea is higher than that in the same volume of other food and drink items that are traditionally considered to promote health,[6] flavonoids and catechins have no proven biological effect in humans.[7][8]
Sejak (세작; 細雀; lit. "thin sparrow"), or dumul-cha (두물차; lit. "second flush tea"), is made of hand-picked leaves plucked after gogu (20–21 April) but before ipha (5–6 May).[77][78][79] The tea is also called jakseol (작설; 雀舌; lit. "sparrow tongue") as the tea leaves are plucked when they are about the size of a sparrow's tongue.[78] The ideal steeping temperature for sejak tea is 60–70 °C (140–158 °F).[80]
A stone mill consists of two granite parts, with a slight opening in the middle called "Fukumi." The tea is funneled in from the top, filling in this small space, and pushed out gradually. Though each stone mill can only grind up to 30-40g of Matcha per hour (that's approximately one tin), only these mills made of granite are able to preserve the color, flavor, and nutritional components of Matcha.
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.
Ceremonial grade: This is the highest quality used mainly in tea ceremonies and Buddhist temples. This is stone-ground into a powder by granite stone mills. It is high-quality and expensive (~$100–140 for 100g). The unschooled drinker is unlikely to notice a large difference between Ceremonial and Premium grade. Ceremonial is characterized by subtle tones of "umami".

Ginger Root, the underground stem, or rhizome, of the plant Zingiber officinale, has been used in many herbal traditions since ancient times. In Ayurveda, Ginger is known as the wonder herb, and it's no wonder, since Ayurveda employs Ginger for a wide variety of health applications, including digestive support. Historically, Ginger Root was also one of the most respected herbs for supporting joint health. Additionally, Ginger Root has been traditionally used to support healthy peripheral circulation; and can aid in warming up cold hands and feet, and will also promote sweating when needed.
It’s important to note that herbs can have powerful effects on the body when taken in large amounts, so use the tea as directed. Also, stay hydrated. Because several of these herbal ingredients are diuretics, your body will be losing fluids and you’ll be passing more urine than usual. It’s important to replenish the fluids within your body to avoid dehydration.

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.

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).
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?
Every day, countless people throw away valuable antioxidants and minerals. While seemingly unimaginable, that’s exactly what happens when you brew a cup of green tea because water can only extract a fraction of green teas benefits. The majority actually remains unused, trapped in the tea leaves. In reality, the only way to truly take advantage of green teas full potential is to consume the entire leaf. But that doesn’t mean you need to start eating tea leaves. The simplest solution is to just enjoy a bowl of matcha. Because matcha is straight, stoneground tea leaves, matcha provides you with green teas powerful arsenal of vitamins, minerals, antioxidants, and amino acids in a way no other green tea can.

contains antioxidants, including polyphenols such as epigallocatechin gallate (EGCG), which can powerfully quench damaging “free radicals,” metabolic byproducts that are chemically reactive and can damage cells. According to a study published in the European Journal of Clinical Nutrition, the polyphenols found in green tea provide six times the radical-quenching potential of those found in black tea.

In this traditional Japanese preparation, the powder is sifted through a fine mesh sieve and measured into a special bowl called a chawan. Hot water is added slowly while whisking briskly in a W pattern with a bamboo whisk called a chasen until smooth with a foamy froth on top. Matcha can have a slight astringent note and is usually served with a small sweet confection called a wagashi. Because of this complementary relationship with sweets and reputed green tea health benefits, it has become a favorite ingredient for chefs and confectioners.
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.

“Specific detox teas offer added benefits in the additional ingredients,” says Villacorta. Herbs like lemongrass, ginger, dandelion, and milk thistle all contain properties said to support a healthy liver, one of those organs in charge of your natural detoxifying process. Ginger has also been proven to alleviate oxidative stress within the liver, which indirectly helps the organ perform its cleaning task more efficiently, he says.


The Japanese tea ceremony, still called The Way of Tea, is a revered practice in Japan and is centered around the art of preparing and presenting matcha in an almost meditative fashion. It was originally developed as a spiritual practice and the principals of the practice—harmony, respect, purity, and tranquility—are still central to tea ceremony today.
Rooibos tea can be useful for small children who suffer from colic or stomach pain. You may add some sweetened milk to farm direct red rooibos tea to improve the flavor and make it more palatable. This is actually why rooibos tea is a well-known health aid. Many South African women claimed that this plant was very soothing for their colicky infant. 

Rooibos grades are largely related to the percentage "needle" or leaf to stem content in the mix. A higher leaf content results in a darker liquor, richer flavour and less "dusty" aftertaste. The high-grade rooibos is exported and does not reach local markets, with major consumers being the EU, particularly Germany, where it is used in creating flavoured blends for loose-leaf tea markets.


facilitates the burning of body fat. Green tea promotes the body’s ability to burn fat through thermogenesis and fat oxidation. A study published in The American Journal of Clinical Nutrition found the combination of polyphenols and caffeine from an extract of green tea resulted in a “significant increase” of energy expenditure compared to placebo.

To cut down on aches and pains, try to sip four cups of green tea a day. The tea contains quercetin, a chemical compound that acts as a powerful anti-inflammatory and antioxidant. In a recent study conducted at Case Western Reserve University, researchers gave mice the equivalent of four cups of green tea a day, then gave them a substance that would normally produce rheumatoid arthritis. The tea-drinking mice were far less likely to develop arthritis than mice that drank water. According to the Iowa Women’s Health Study, women who drank more than three cups of tea a day were 60 percent less likely to develop rheumatoid arthritis than non tea drinkers. Other research has found that tea’s polyphenols—antioxidant properties—are also anti-inflammatory and improve arthritis-related immune responses. Did you know other teas also act as natural home remedies for arthritis pain?
Steamed: Like most Japanese teas, the tea leaves destined for matcha are first steamed. The leaves are treated briefly with steam heat within hours of plucking to both halt the oxidation process and bring out the rich green color of the shade-grown tea leaves even more. The steaming process creates a unique flavor profile that is often described as sweet and vegetal.
We’re wary of any trend that involves detoxing with just a drink. By now, we’re all pretty aware that liquid diets can’t sustain our active bodies for very long, and most of the drinks celebrities swear by have little actual detoxifying effects. But a teatox, or tea detox or tea cleanse, is a gentler approach to the whole idea, namely because it involves adding a few herbal cups to your existing, healthy diet—instead of replacing meals entirely.
Usucha, or thin tea, is prepared with approximately 1.75 grams (amounting to 1.5 heaping chashaku scoop, or about half a teaspoon) of matcha and approximately 75 ml (2.5 oz) of hot water per serving, which can be whisked to produce froth or not, according to the drinker's preference (or to the traditions of the particular school of tea). Usucha creates a lighter and slightly more bitter tea.
Green tea leaves are initially processed by soaking in an alcohol solution, which may be further concentrated to various levels; byproducts of the process are also packaged and used. Extracts may be sold in liquid, powder, capsule, or tablet form.[4] Decaffeinated versions are also available.[9] Green tea extract supplements are accessible over the counter in various forms.[10]
This best-selling detox tea has a loyal following, with thousands of reviewers claiming that it helped with excess bloating, daily digestive issues, and ultimately contributed to weight loss when consumed alongside a balanced diet and regular exercise. Made with green tea leaf, matcha green tea, and guarana seed, this tea blend is quite caffeinated — so don't sip it before bedtime. 
If not taken with sugar, the alkaline nature of green tea helps reduce the blood glucose level. Moreover, the antioxidant and astringent qualities of green tea ensure good health and better functioning of the pancreas. Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
Matcha is a high-grade green tea ground into powdered form. The green tea powder is whisked into hot water, instead of steeped, to form a frothy drink. The meditative act of preparing, presenting, and sipping matcha is the backbone of the Japanese tea ceremony. While matcha’s origins are ceremonial, the green tea powder is widely popular around the world in beverages like tea lattes or boba tea, and as a cooking ingredient in everything from ice cream to salad dressing.
In 2004, scientists at the University of Newcastle studied the effects of black and green tea on Alzheimer’s disease. In laboratory studies, both teas prevented the breakdown of acetylcholine, the neurotransmitter strongly linked with memory. The teas also inhibited enzymes known as BuChE and beta-secretase. These enzymes are found in protein deposits found in the brain of Alzheimer’s patients. (7)

"It's only in the last 10 year that Western science has tried to look at antioxidant activities of tea," says Dave Ringer, PhD, scientific program director at the ACS. "It's a young science. Generally, it is felt that tea can inhibit the initiation of cancer and delay its progression in animal studies. But we don't really have large well-controlled epidemiological studies to look at this yet [in humans], because you need to correct for the effects of other dietary components."
Some of the antioxidants and healing compounds found in green tea include polyphenols, catechins and various other types of flavonoids — the same anti-aging compounds found in things like red wine, blueberries and dark chocolate. Despite that it does contain small amounts of caffeine, green tea consumption has been associated with more health benefits than even many of the healthiest foods available to us. Studies have found that the benefits of green tea are due to the fact green tea contains more healing compounds than many other herbs, spices, fruits and vegetables, truly making it a powerful “superfood.”
The rooibos plant is endemic to a small part of the western coast of the Western Cape province of South Africa. It grows in a symbiotic relationship with local micro-organisms. Scientists speculate that climate change may threaten the future survival of the plant and the R600-million (approximately €43-million in March 2017) rooibos industry. Some claim that increasing temperatures and decreasing rainfall may result in the extinction of the plant within the next century.[15]
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!

Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
Aspalathin is one of the rare antioxidants found in rooibos tea and it has a number of unique qualities. It can help balance blood sugar, improve insulin resistance and glucose absorption by muscles, and boosts insulin secretion from the pancreas. This results in an ideal defensive shield against developing type II diabetes, one of the most widespread and dangerous conditions currently sweeping the world.
Unsweetened brewed green tea is a zero calorie beverage. The caffeine contained in a cup of tea can vary according to the length of infusing time and the amount of tea infused. In general, green tea contains a relatively small amount of caffeine (approximately 20-45 milligrams per 8 ounce cup), compared with black tea, which contains about 50 milligrams and coffee with 95 milligrams per cup.
Our green tea is passed through a steaming treatment before rolling. Steaming applies light heat to the leaves to help halt the oxidation process before the leaves are rolled into shape. Steaming also helps expose the fresh, grassy flavor of the leaf. Green tea leaves are not allowed to oxidize after rolling, which is why they remain light color and flavor.
Unlike traditional green tea, matcha preparation involves covering the tea plants with shade cloths before they’re harvested. This triggers the growth of leaves with better flavor and texture, which are hand selected, steamed briefly to stop fermentation, then dried and aged in cold storage, which deepens the flavor. The dried leaves are then stone-ground into a fine powder.
can increase energy and mental focus. Green tea contains a small amount of caffeine, which a 2008 study in Nutrition Bulletin found can improve mood, cognitive function and physical performance. Green tea contains less caffeine than does coffee, and provides L-theanine, an amino acid shown to promote a state of calm awareness. Result: green tea provides the benefits of alertness associated with caffeine without the “jittery” feeling often experienced as a side effect of coffee.
Since green tea is less oxidized than its black tea cousin, it is technically fresher and more delicate, so it should be consumed more quickly for maximum flavor. Green tea is best consumed within six months to a year of purchase. You should also take care to store your green tea in a cool, dark place, away from light, oxygen, moisture and fragrant pantry companions like coffee or spices.
