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]
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.

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.
Green tea is considered one of the world's healthiest drinks and contains one of the highest amounts of antioxidants of any tea. Natural chemicals called polyphenols in tea are what are thought to provide its anti-inflammatory and anti-carcinogenic effects. Green tea is approximately 20-45 percent polyphenols by weight, of which 60-80 percent are catechins such as EGCG. Catechins are antioxidants that are said to help prevent cell damage.
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 hot with chefs, not just as a beverage, but as an ingredient in both sweet and savory dishes. If you Google matcha recipes, you’ll find everything from matcha muffins, brownies and puddings, to matcha soup, stir frys, and even matcha guacamole! I love experimenting with it, and in a previous post I wrote about the potential weight loss benefits of umami foods (The Surprising Food Flavor That Can Help You Shed Pounds). But due to concerns about lead, I recommend avoiding “matcha madness.” Even with superfoods, you can get too much of a good thing (check out my article 4 Superfoods You Might Be Overeating). So look for pure, organic, quality matcha, and enjoy it in moderation.
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.
Sencha: Sencha comes from the same plant, but in this green tea variation, the leaves are from the middle of the branch and are bigger, older, and less tender than Gyokurocha. This variety gives a clear, light green tea when brewed as well. Naturally, it is more bitter and stronger than the former variety. Being of less noble origin (middle of the branch) and having more caffeine and tannin, it is cheaper and more popular than Gyokurocha.
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.

Green tea is processed and grown in a variety of ways, depending on the type of green tea desired. As a result of these methods, maximum amounts of polyphenols and volatile organic compounds are retained, affecting aroma and taste. The growing conditions can be broken down into two basic types − those grown in the sun and those grown under the shade. The green tea plants are grown in rows that are pruned to produce shoots in a regular manner, and in general are harvested three times per year. The first flush takes place in late April to early May. The second harvest usually takes place from June through July, and the third picking takes place in late July to early August. Sometimes, there will also be a fourth harvest. It is the first flush in the spring that brings the best-quality leaves, with higher prices to match.

In 2009, King’s College researchers found that epicatechin may protect brain cells through mechanisms unrelated to its antioxidant ability, as epicatechin is one of the few flavonoids that can cross the blood-brain barrier. The King’s College researchers reported that somehow epicatechin protects brain cells from the negative effects of beta-amyloid plaques, although the exact mechanism of how this works is still not entirely know.

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.
Rooibos is sometimes used as substitute for milk with colicky babies, says Alvaro Viljoen, PhD, of the department of pharmacy at the University of the Witwatersrand. And the health benefits of Rooibos are bound to make it a favorite, he says: rich in antioxidants, rich in vitamin C, caffeine-free, and low in tannins, the residue in teas that can sometimes cause digestive problems.
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.
