In Canada, green tea is defined as a dry-based mixture and the sale of it is regulated by the Canadian Food Inspection Agency (CFIA). It is one of the foods for which a standard of identity is specified according to the Food and Drug Regulations. It should contain not less than 33% water-soluble extractive (determined by official method FO-37 which is the determination of water-soluble extractive in tea) and the total ash should between 4% to 7%.
One study that was published in the February 2010 issue of the Journal of Agricultural and Food Chemistry investigated the effects of catechins on eye diseases and found that consuming more catechins may help protect the eyes from oxidative damage and vision loss. Scientists involved in the study found evidence that catechins can pass from the digestive tract of rodents to the tissues of their eyes and reduce oxidative stress for up to 20 hours after ingestion.

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.”
Rooibos contains polyphenols that have anti-inflammatory, antiviral, and antimutagenic qualities. Polyphenols are organic chemicals that are often praised for their antioxidant capabilities. Studies suggest that regularly drinking organic red rooibos tea provides the liver with potent antioxidants, helping the organ to improve detoxification. Antioxidants act as scavengers of free radicals throughout the body, which are detrimental byproducts of cell metabolism that can cause cancer and heart diseases. Aspalathin and nothofagin are two other vital antioxidants that rooibos tea contains, making it a great beverage to boost your immune system and protect your body against all types of diseases.
Houjicha: Also spelled as “Hojicha”, this is not a pure or absolute green tea. Rather, it is a mixture of green tea and powdered roasted cereals such as wheat, barley, or rice. The quality and price of this variety depend upon the percentage or ratio of green tea to cereal content. The better ones, which have more green tea in them, are more expensive and have a greener look when brewed; on the other hand, those with higher grain contents yield a golden brown color and are cheaper.
Matcha is green tea that has been specially grown and processed. Twenty days before harvest, the leaves are shaded from direct sunlight, which amps up the chlorophyll levels (and accounts for that Kermit green color) and increases the production of the amino acid L-Theanine, which is thought to promote relaxation even as the tea gives you a caffeine jolt. The leaves are hand-picked and laid out to dry. Once they are rid of their veins and stems, they’re stone-ground into what is finally matcha.
Several large, population-based studies show that people who regularly drink black or green tea may be less likely to have heart attacks and strokes. However, people who drink tea tend to be different from people who don't drink tea. "We can't quite disentangle whether it's their tea drinking or something else those people are doing that lowers their risk of cardiovascular disease," explains Dr. Sesso. "Some experts believe that tea may have cardiovascular benefits, but it's not considered a slam-dunk proposition."

Studies in laboratory animals have found that green tea polyphenols inhibit the growth of esophageal cancer cells (in line with its anti-cancer properties). Other clinical studies have found that green tea offers protection against the development of esophageal cancer, particularly among women. However, one large-scale population-based clinical study found just the opposite: drinking green tea was associated with an increased risk of esophageal cancer, and the stronger and hotter the tea, the greater the risk. It seems that if the water is very hot, it can damage the esophagus and lead to long-term adverse consequences. So just make sure the tea you drink isn’t extremely hot.
I boil 8oz of water and put 2 tea bags in at night. If I feel very bloated when I wake up, I boil another 8oz of water and put 2 tea bags in. If you are trying to lose weight, I HIGHLY recommend drinking this tea at night. I feel amazing when I wake up in the morning. I was able to lose 60 pounds and I owe a lot of it to this tea for taking the extra bloating and the edge off. I really enjoy drinking it at night too because it soothes me, and I feel like it helps my body burn more fat as I sleep.
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.
The claims of weight loss within 14 days has worked for many users. V tea T-tox 14 Day Detox Tea works by boosting the body’s metabolism and suppressing appetite. Since it doesn’t have the natural laxative of senna leaves, you will be not be rushing to the washroom frequently. So, it is completely safe to take this tea to work or school for consumption later in the day.
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.
Grown under shade for three weeks prior to plucking, gyokuro is one of the most exclusive varieties of tea produced in Japan. 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.
Ready to unwind for the evening? Nothing does the job better than a warm cup of 310 detox tea to help you digest after dinner and get you in a nice, relaxed state before bedtime. Though 310 Tea does contain some natural caffeine, it is such a tiny amount (22.7mg compared to 95mg in the average cup of coffee), that many people can have it at night and it does not affect their sleep.
On this episode of Consumed, host and Eater Drinks editor Kat Odell looks into the matcha production process — how it differs from that of more traditional steeped green tea, and how two of New York's noted matcha purveyors (Ippodo Tea Company and Matchabar) are working with the product today. Watch the video above for a lesson in powdered green tea; if your interest is piqued, check this map for the best places to drink matcha across the country, and these recipes for making iced matcha drinks at home, perfect for the summer.
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.
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). 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. The ideal steeping temperature for sejak tea is 60–70 °C (140–158 °F).
So what are the best detox teas to choose? If you’re really focused on a start-and-stop teatox (rather than just incorporating detox teas into your diet), check out programs like SkinnyMe Tea, which offers 14- or 28-day packages of high-quality, loose-leaf herbs to steep. Or save a little cash and try one of these four off-the-shelf detoxifying varieties, recommended by Lagano and Villacorta.
Because matcha is incorporated into water (whereas other green teas are steeped in water), you consume the entire leaf—and thereby the full effects of its antioxidants, vitamins, and caffeine. Fans say matcha provides a calmer, more sustained energy burst than coffee or espresso, and since it’s less astringent, it mingles more readily with fruit, yogurt, and herbs in wake-up drinks like smoothies and juices.
Rooibos (pronounced ROY-boss) appears to be matching -- and possibly besting -- the health benefits claimed for other more established teas. A favorite among South Africans for years, the beverage is said by some to have 50% more antioxidants than are found in green tea. Antioxidants are the organic substances believed to scavenge "free radicals," the toxic by-product of natural biological processes that can damage cells and lead to cancer.
The first early harvest of tea, plucked before the first flush, is called shincha. Shincha is made from the youngest new growth leaves, and is plucked from early April to early May. Shincha typically refers to the early harvest of sencha, but can refer to any type of tea plucked early in the season, before the main harvest. Because of the limited quantities in which it is produced, shincha is highly prized and expensive to obtain.
2. Lemon or ginger tea: This revitalizing tea is great for the morning because the light amount of caffeine will wake you up without wreaking havoc on your stomach. Plus, the health benefits of ginger include reducing inflammation and controlling blood sugar, so you can feel good drinking this soothing tea. (Twining’s Lemon & Ginger, $3; twiningsusa.com)
The next morning, I had a bagel and one daily tea, as instructed. I felt my stomach become uneasy as most stomachs do when they’re working their “digestive magic.” Suddenly, the worst cramp of my life hit me out of nowhere. It was the sharpest PANG I’ve ever felt as it made its way from my stomach to my chest. As a reflex, I jumped up. That’s when I felt another wave of pain and swiftly made my way to the restroom.
Shade grown: All matcha is made from shade-grown tea leaves—a labor-intensive process where tea bushes are protected from the sun and light is filtered to the bushes in a very controlled manor. Shading boosts the chlorophyll production in the plant, giving the leaves a rich green color. The lack of sun reduces the plant’s photosynthesis of the leaves, which in turn alters the naturally occurring levels of caffeine, flavanols, sugars, antioxidants, and theanine. By controlling the sun exposure, tea producers can significantly alter the chemical make-up and flavor of the final tea leaves.
These are some of the many benefits but the reality is one cup of tea a day will not give you all the abundant gains. The jury is out on how many cups are necessary; some say as little as two cups a day while others five cups. If you are thinking of going down this route, you may want to consider taking a green tea supplement instead (it would keep you out of the bathroom).

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.
Day 2: I hopped out of bed, made my 2nd cup of tea, then went about my day. As the hours wore on, though, I grew discouraged. The reviews I had read and testimonials from friends had assured me that the tea was going to start working its magic very quickly, but my stomach still felt perfectly normal and average. Since I am the perfect blend of spontaneous, self-destructive, and optimistic, I went ahead and made myself my 3rd cup in 24 hours (Remember that last night I drank it at night instead of the recommended first-thing-in-the-morning.).
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.
Researchers from the Netherlands confirmed in a recent study that two green tea compounds, L-theanine and caffeine, can significantly boost levels of attention and alertness, building on what is already known about the brain benefits of green tea. The drink is less likely to make you jittery and anxious than other energy-boosting drinks, because it contains lower levels of caffeine than other teas or coffee. In another study published in the American Journal of Clinical Nutrition, researchers discovered that drinking just one cup of green tea a day made people age 55 and older 38 percent less likely to experience a decline in their mental abilities. Drinking a second cup daily made them 54 percent less likely to show mental declines.
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.
56. For the next 100 days, practice active listening. When someone is talking to you, remain focused on what they’re saying, instead of rehearsing in your head what you’re going to say next. Paraphrase what you think you heard them say to make sure that you haven’t misinterpreted them, and encourage them to elaborate on any points you’re still not clear about.
