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.

Matcha tea has antioxidants such as catechins – EGCG (epigallocatechin gallate), which detoxifies the body. A research study assessing the antioxidant power of this tea has revealed that as compared to other green teas matcha has the highest amount of EGCG. These antioxidants seek out for the oxygen free radicals and neutralize their harmful effects. Thus, protecting the body from the occurrence of disorders or inflammations associated with the oxidative stress.
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.

A book written by Lu Yu in 600-900 AD (Tang Dynasty), "Tea Classic" (simplified Chinese: 茶经; traditional Chinese: 茶經; pinyin: chájīng), is considered important in green tea history. The Kissa Yojoki (喫茶養生記 Book of Tea), written by Zen priest Eisai in 1211, describes how drinking green tea may affect five vital organs, the shapes of tea plants, flowers and leaves, and how to grow and process tea leaves.
Research also shows that green tea lowers total cholesterol, improving the overall cholesterol profile. One population-based clinical study found that men who drink green tea are more likely to have lower total cholesterol than those who do not drink green tea. Other clinical studies that look at populations of people indicate that the antioxidant properties of green tea may help prevent atherosclerosis, particularly coronary artery disease. The benefits also seem to extend to preventing stroke, reducing high blood pressure, and inhibiting the formation of blood clots. Much of the effect may also be due to the ability of green tea to help lower blood sugar and insulin levels.
Day 28: Honesty time — I took several days off. I went away for the long weekend, and I overindulged in Mexican food, wine tastings, and cherry ice cream. When I got home, I was nursing an exhausted body and a bad case of bloat. The solution? To drink my final cup of tea. After drinking it, I went to bed feeling refreshed and lighter, then woke up the next morning ready for a workout and a day back at work.
Experts emphasize that the primary thrust of scientific research has been on the pure tea products -- green, black, or oolong tea, derived from a plant called Camellia sinensis. All of the many other "herbal" or "medicinal" teas found in supermarkets and health food stores may be tasty, and may be good, bad, or indifferent for your health -- but they haven't been the focus of concentrated research, says John Weisburger, PhD, of the American Health Foundation.
Over a thousand years ago, matcha came to Japan as an aid to meditation practice. During long hours of sitting, monks would drink matcha to remain alert yet calm. Modern science has recently confirmed the lessons of centuries of tradition. Matcha is rich in L-Theanine, a rare amino acid that actually promotes a state of relaxation and well-being by acting upon the brains functioning. While stress can induce beta waves an excited, more agitated state, L-Theanine creates alpha waves, which lead to a state of relaxed alertness. And while L-Theanine is common in all tea, matcha may contain up to five times more of this amino acid than common black and green teas.
In 2013, global production of green tea was approximately 1.7 million tonnes, with a forecast to double in volume by 2023. As of 2015, China provided 80% of the world's green tea market, leading to its green tea exports rising by 9% annually, while exporting 325,000 tonnes in 2015. In 2015, the US was the largest importer of Chinese green tea (6,800 tonnes), an increase of 10% over 2014, and Britain imported 1,900 tonnes, 15% more than in 2014. In 2015, Kenya was the largest exporter of black tea in the world (443,000 tonnes).
Most detox tea blends contain 60 milligrams or more of caffeine, which is less than a cup (eight ounces) of black coffee, which packs about 95 milligrams of caffeine. But it’s the combination of caffeine with other ingredients, like nettle leaf and dandelion leaf, that could upset your stomach and force you to take even more bathroom breaks, especially if you’re predisposed to stomach sensitivity or gastrointestinal issues.
Even with negligible evidence that matcha can boost a weight-loss regimen, the substance remains heavily endorsed. Philadelphia-based nutritionist Marjorie Cohn regularly enjoys matcha, adding it to her smoothies and chia seed pudding — even mixing it into her recipe for organic vanilla ice cream. She often recommends it to clients looking to cut out coffee, or to “hard core caffeine addicts” prone to reaching for a second or third cup of coffee.
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.
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.
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?
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.
In January 2015, we wrote about the rapid rise of matcha on the American beverage landscape and posed the question, “Have we reached maximum matcha saturation?” Three years later, we're living amid matcha croissants, matcha custard pie, matcha face masks, matcha lifestyle guides and $50 cups of matcha itself. Clearly, the answer was "No." But what is this powder we're whisking into green lattes, baking into doughnuts, blending into smoothies, and adding to our fish fillets?
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.
