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:
The best Matcha Green Tea comes from the first flush, baby green tea leaves that grow during the spring. Only the newest buds of the shade grown tea plants are hand-picked for Premium Matcha production. The window for ideal Matcha Green Tea growth is very limited, which is one of the reasons that Matcha is one of the more expensive teas on the market.

Matcha, like other green teas, contains a class of antioxidants called catechins. Matcha is high in a catechin called EGCG (epigallocatechin gallate), which is believed to have cancer-fighting effects on the body. Studies have linked green tea to a variety of health benefits, like helping to prevent heart disease, type 2 diabetes and cancer, and even encouraging weight loss. However, it’s important to note that much of this research isn’t from clinical trials that show green tea causes a benefit. Instead, it’s largely from population-based studies, where researchers look at groups of people who drink green tea and compare their health outcomes to groups that don’t drink it. Studies have shown associations between tea and better health, but causation is not yet proven. Matcha is even less studied than brewed green tea.

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.

Green tea can lower and help stabilize your blood sugar levels (glucose levels); in fact, studies show that green tea can even improve insulin sensitivity and reduce blood sugar levels. One study among Japanese individuals found that those who drank the most green tea had a very significantly lower risk of developing type II diabetes. Other studies have shown similar results.
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.

Total Tea Gentle Detox tastes great and is fast acting. Initially, you may have to go to the washroom frequently as the tea first cleanses the colon. After 2-3 days, bloating and any discomfort will disappear. You will also start to notice an improvement in your energy levels and productivity. And soon after, you will see visible changes in your appearance, get a flat tummy, and be highly motivated to eat and live healthily.
In addition to actual tea, detox concoctions typically include additional herbs, which may be designed to curb appetite, rev metabolism, or boost weight loss in other ways. One example is senna, a plant with a natural laxative effect. According to the Natural Medicines Comprehensive Database, the potential side effects of senna use may include abdominal pain and discomfort, cramps, bloating, gas, nausea, and diarrhea; excessive use can lead to potassium depletion and other electrolyte abnormalities, which can trigger muscle spasms and an abnormal heart rhythm. Another popular ingredient in weight loss teas is guarana, a plant that's often added to energy drinks. Its side effects are commonly related to its caffeine content, which may include nervousness, restlessness, stomach irritation, nausea, vomiting, headache, anxiety, agitation, ringing in the ears, and fast heart and breathing rates. Bottom line: Do your homework about exactly what's in a product before you put it in your body. Even "all-natural" substances can have potential side effects, especially if they're overused, combined with other supplements or medications that result in negative interactions, or if taken by those with pre-existing medical conditions.
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?
The polyphenols in green tea, which include multiple subcategories of polyphenols like flavonoids and catechins, can reduce the formation of free radicals in the body, protecting cells, molecules, and other structures from damage. One of the most active and powerful antioxidant polyphenols in green tea is epigallocatechin-3-gallate (EGCG). EGCG has been studied to treat a wide variety of diseases and may be one of the main reasons green tea has such powerful medicinal properties. Beyond EGCG, other polyphenol catechins in green tea include catechin, gallocatechin, epicatechin, epigallocatechin, and epicatechin gallate.

According to the National Cancer Institute, the polyphenols in tea have been shown to decrease tumor growth in both animal and laboratory studies. Researchers believe that it is the high level of polyphenols in tea that help kill cancerous cells and stop them from growing, although the exact mechanism by which tea inhibits and prevents cancerous cells is uncertain.


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]
Indigenous to the Western Cape of South Africa, rooibos (Aspalathus linearis) is a shrub with long, needle-shaped leaves that turn red upon fermentation. When you drive through the countryside north of Cape Town, you see rooibos everywhere. Rooibos is a traditional beverage of the native Khoi people of the Cape area, though it has become more popular in recent years due to word spreading about its high antioxidant value. Traditionally, the native people harvest the leaves, bruise them with hammers, ferment them and dry them. The result is a red, astringent tea that refreshes and does not cause jitters.
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.

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.
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".

Neither red nor black tea is to be confused with Rooibos, often called “Red Bush Tea” or “Rea Tea” for short. Rooibos (Aspalathus linearis) is a South African plant that is a member of the legume family and is not related to the tea plant (Camellia sinensis). Rooibos has a very different taste and feel than red (or black!) tea, it is much sweeter and lighter than black tea, although it is often mixed with sugar and cream or a lemon as you might find heavy black tea drinking countries such as England or the United States.
Unbeknownst to many, green tea actually comes from the same plant from where normal tea is obtained. Scientifically, it is known as Camellia sinensis. In fact, it is the same tea but it is processed differently. The normal black tea is obtained by fermenting the tea leaves. This fermentation changes its color and flavor while raising the level of caffeine and tannin in it. On the other hand, in the case of green tea, the tea leaves are dried or slightly steamed but not fermented. This is what makes it look green when it’s brewed.
"Tea is a good source of compounds known as catechins and epicatechins, which are thought to be responsible for tea's beneficial health effects," says Dr. Howard Sesso, associate professor of medicine at Harvard Medical School and associate epidemiologist at Brigham and Women's Hospital. These compounds belong to a group of plant chemicals called flavonoids. Research suggests that flavonoids help quell inflammation, and that in turn may reduce plaque buildup inside arteries. Green tea has slightly higher amounts of these chemicals than black tea. Both black and green teas also contain modest amounts of caffeine, ranging from about 20 to 45 milligrams per 8-ounce cup. That's roughly half the amount of caffeine in the same amount of coffee.
The detox period lasts for about 30 days, and most companies recommend taking a significant break (around six weeks) between detox sessions if you plan to do it more than once. Many detox tea companies are also quick to note — in small print, of course — that their teas are not suitable meal replacements and are meant to be used in conjunction with healthy eating and regular exercise.
Rooibos tea is anti-inflammatory in nature, which means that it reduces blood pressure and scavenges free radicals like other antioxidants. Quercetin, another powerful antioxidant found in rooibos tea, has been linked to preventing a wide variety of heart conditions. It promotes an increase in HDL cholesterol (good cholesterol) and inhibits the LDL cholesterol (bad cholesterol) from binding to the walls of arteries and blood vessels.
