ODS seeks to strengthen knowledge and understanding of dietary supplements by evaluating scientific information, supporting research, sharing research results, and educating the public. Its resources include publications (such as Dietary Supplements: What You Need to Know), fact sheets on a variety of specific supplement ingredients and products (such as vitamin D and multivitamin/mineral supplements), and the PubMed Dietary Supplement Subset

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. 

Scientists have also discovered that the antioxidants flavonoids may also protect the brain from oxidative stress. The scientists extrapolated that a human would need to drink about three liters of liquid infused with 0.5 percent of the catechins to get similar effects. However, because humans ingest other antioxidants in the form of vitamins and plant polyphenols, it’s likely that a much lower quantity could be effective in protecting memory.

In a decade-long study of Japanese adults, death from all causes together, and also death from specifically heart disease and stroke, were all reduced in both women and men who drank the most green tea (5 or more cups per day) versus those who drank less than one cup per day. Another study found that those who drank the most green tea were 76% less likely to die during the 6 year study period.
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.

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.


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.
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.).

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).
One of the key components in Matcha is the amino acid L-theanine, which is found almost exclusively in shade-grown green teas like Matcha. When L-theanine is combined with the natural caffeine in tea, it metabolizes more slowly, releasing the caffeine over a longer period of time and providing a stable three to six hour long energy boost (versus coffee caffeine at an hour to an hour and a half).
It’s become such a fashionable beverage that, last summer, the New York Post ran a story about how Victoria’s Secret models were flocking to Cha Cha Matcha, a hipster spot fluent in the preparation of various matcha-based miracle potions. A search for where to get “matcha” in New York, New York on Yelp yielded some 1400 plus results. Even mass market coffee purveyors like Starbucks have made matcha their mantra, with a vast range of offerings to cash in on the craze.
The ingredients in one bag of Yogi DeTox tea are quite extensive. They are reportedly all natural and plant-derived. The product label lists the following, many identified as organic: Indian sarsaparilla root, cinnamon bark, ginger, licorice, burdock, dandelion, cardamom, clove, black pepper, juniper berry, long pepper berry, Philodendron bark, rhubarb, skullcap root, Coptis, Forsythia, gardenia, Japanese honeysuckle, and winter melon.

Like black and green tea, rooibos is rich in polyphenols, such as rutin and quercetin. Cell and animal studies, mostly from South Africa, have shown that rooibos extracts have antioxidant, immune-stimulating, and anti-cancer properties. But studies of rooibos tea in people are limited. There’s little or no evidence to back claims that it relieves constipation, headaches, eczema, asthma, insomnia, high blood pressure, mild depression, ulcers, diabetes, and so on.

According to a report published in the Journal of the American College of Nutrition, “Tea is the most consumed drink in the world after water.” (2) What is green tea good for? According to dozens of studies, regularly drinking green tea may reduce your risk of developing heart disease or Alzheimer’s, help you maintain better bone mineral density, ward off eye diseases that affect vision in older age, prevent strokes, and even extend your life.
Jump up ^ Horaido. "H4". JP: Dion. Archived from the original on 2005-04-06. Matcha used to be sold in packages of 10 monme (ancient measure of about 3.75 g, or 37.5 g for the package) and most tea masters considered that one package provided for 20 usucha (about 1.8 g each) or 10 koicha (about 3.75 g each). This is why today's traditional packaging is 40 g (the closest to 10 monme)

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%.[92]
I ordered this product after many phenomenal reviews about it, and its miraculous properties to aid in your weight loss efforts. After having it used for several weeks in a row and following a healthy diet and exercise plan, I have not seen any changes in my weight, or any benefits from this tea. Unfortunately this does not mean that it would not work for you, as every human physiology is quite different. The one positive about this tea that I can give is that it has a quite pleasing taste.

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).
This is yet another powerful benefit of green tea. Astringent substances trigger contractions in muscles and tissues while toning up muscles and skin. Even if you do not wish to drink green tea, a simple, daily mouthwash with it can cause sufficient contraction in your gums to keep them firm and tight on the teeth, thus preventing loosening and loss of teeth. You can also wash your hair with green tea and feel it grow stronger and healthier every day.
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.
A study suggests that theanine found in matcha tea acts as a neurotransmitter. It exerts a calming effect on the brain without causing any drowsiness. This soothing effect helped the Buddhist monks in maintaining deep concentration during their meditation sessions and was the main reason behind its popularity. Another study has revealed the anti-stress effects of theanine present in this tea, which assists in reducing the physiological and psychological stress responses by inhibiting the neuron excitation. Matcha tea is also believed to boost memory and concentration.
Premium grade: High-quality matcha green tea that contains the full nutritional content[citation needed] and uses tea leaves from the top of the tea plant. Price point (~$50–80 for 100g). Best for daily consumption and contains the full range of antioxidants, vitamins and minerals[citation needed]. Is characterized by a fresh, subtle flavour. Usually perfect for both new and everyday matcha drinkers alike.
Gyokurocha: In this variety, the tea leaves are plucked from the tip of the branches. When brewed, the color is clear green. Being picked from the tip, this variety has the best taste and fragrance, and this variety is also considered the best in terms of health. Furthermore, it is less bitter, as it contains lesser tannin and caffeine since the plucked leaves are younger and still budding. The only drawback to gyokurocha is the high cost, but as we all know, truly high-quality solutions for health never come cheap!
Gardenias were originally found only in China and Japan, but today there are over 200 different species of gardenia, mostly hybrids, throughout the world. Gardenia fruit is used extensively in Traditional Chinese Medicine (TCM), where it is known as zhi zi. TCM uses gardenia primarily to promote calm, but it is also used to support bladder and urinary tract health.
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).
Others credit various Buddhists in the 500s BC and subsequent centuries for the discovery of tea. Buddhists would travel between India and China spreading their religion, culture and ritual of tea. Buddhist monks grew, harvested and produced tea much like their Catholic counterparts in European monasteries did with grapes and wine. The monks’ habit of tea drinking for physical refreshment, to aid meditation and as a substitute for alcohol developed into a spiritual and social practice that spread across China.
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.[66]
African red tea, more commonly called rooibos tea, comes from the South African red bush and is naturally caffeine-free. It can be in the form of either green or red rooibos tea -- but red tea, the fermented variety, is more common. Rooibos is naturally low in calories and is naturally sweet-tasting, making it an ideal replacement for a less healthy, high-sugar drink. Rooibos also has a number of health benefits, including helping you meet your weight-loss goals.
Day 14: At halfway through my detox, I finally officially figured out what works for me and my body. The plan: my standard first-thing-in-morning cup of coffee, then an iced version of the tea to drink with me throughout the day. I sip it all day long, and it’s both refreshing and hydrating. I can very honestly say I feel AWESOME. I’m having no kinds of digestive problems, I feel lighter while running at the gym, and my stomach is significantly less bloated and more toned.

Matcha tea rich in EGCG  helps fight various bacterial, viral, and fungal infections. According to a research study,  EGCG binds to the lipid membrane and exerts inhibitory action against the growth of various human pathogens. These include influenza A virus, hepatitis B, and C virus, herpes virus, adenovirus Staphylococcus aureus bacteria, and Candida albicans yeast.

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.
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.
