The traditional Japanese tea ceremony centers on the preparation, serving, and drinking of matcha as hot tea and embodies a meditative spiritual style. In modern times, matcha also has come to be used to flavor and dye foods such as mochi and soba noodles, green tea ice cream, matcha lattes, and a variety of Japanese wagashi confectionery. Matcha used in ceremonies is referred to as ceremonial-grade matcha, meaning that the matcha powder is of a high enough quality to be used in the tea ceremony. Lower quality matcha is referred to as culinary-grade matcha, but there is no standard industry definition or requirements for either.
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.
It isn’t difficult to live the high antioxidant lifestyle, taking in foods, herbs and teas that will protect your body in many ways, reduce the risk of various chronic and degenerative diseases and make you feel good. As Hippocrates remarked in his credo “Let thy food be thy medicine.” Drink Rooibos for taste or drink it for health. In either case, you’ll derive innumerable benefits.
To make green tea, the leaves are quickly steamed or heated to stop oxidation, the chemical process that causes browning. To make black tea, the leaves are crushed, torn, curled, or rolled and allowed to oxidize before being dried. This additional processing step degrades some of the flavonoids. As a result, black tea has slightly lower amounts of flavonoids than green tea.
About 2 weeks before harvest, farmers build structures around the plants to shade them, leaving them almost in the dark. It’s thought that this makes the leaves softer, sweeter, and brighter. After harvest, the tea leaves are quickly steamed, then dried and put into heated ovens for 20 minutes or so. Workers then remove stems, twigs, and other unneeded parts and grind the leaves into powder.
Green tea has slightly more antioxidants compared to black tea, although both are still great sources. The ORAC value (antioxidant content) of brewed black tea is 1,128 while green tea is slightly higher at 1,253. Black tea and green tea both contain antioxidants, including polyphenols. Some research shows that green tea contains more than four times the catechins that black tea does. Both types can contribute antioxidants to your diet and have been shown to have antiviral, anti-inflammatory, detoxifying and immune-stimulating effects.
Studies on green tea’s impact on cancer have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some clues that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's web site says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer."
On 17 June 2011, at Charles de Gaulle airport in Paris, France, radioactive cesium of 1,038 becquerels per kilogram was measured in tea leaves imported from Shizuoka Prefecture, Japan as a result of the Fukushima Daiichi nuclear disaster on 11 March, which was more than twice the restricted amount in the European Union of 500 becquerels per kilogram. The government of France announced that they rejected the leaves, which totaled 162 kilograms (357 lb).
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?
One of Japan’s own Zen priests studying in China’s Buddhist monasteries returned to Japan in the early 12th century with tea plant seeds and bushes. The young priest, called Eisai, used his experience in China growing and drinking “beaten tea” to popularize what he called “the way of tea” as a meditation ritual within his community of Japanese Buddhist monks. Eventually, he spread the tea drinking custom throughout the rest of Japan.
2. Enables digestion: Red tea is caffeine-free and also free of tannins. This element is present in other teas and is known to cause digestive issues among many people. Red tea is a storehouse of antispasmodic elements, preventing diarrhea and gastric issues. It has no oxalic acid, this makes it suitable for those who are prone to developing kidney stones.

An animal study published in 2009 in “Phytomedicine” found that green rooibos tea helped regulate glucose metabolism, preventing increases in fasting blood glucose levels during the course of the five-week study. This effect is a result of aspalathin, a compound found in green rooibos. Poor glucose tolerance and high fasting glucose levels are signs of type-2 diabetes and are common in obesity. The study suggests rooibos tea may help keep blood glucose levels in check, preventing sharp spikes and falls that can trigger symptoms of hunger and possibly leading to lower calorie consumption.
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).
Rooibos grades are largely related to the percentage "needle" or leaf to stem content in the mix. A higher leaf content results in a darker liquor, richer flavour and less "dusty" aftertaste. The high-grade rooibos is exported and does not reach local markets, with major consumers being the EU, particularly Germany, where it is used in creating flavoured blends for loose-leaf tea markets.
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.
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.

Matcha contains a healthy form of caffeine; not to be mistaken with the one present in regular coffee. This unique form of caffeine known as theophylline sustains the energy levels without any adverse effects. The slow release of energy due to theophylline helps in supporting the functionality of adrenal glands. It also maintains optimum hormonal levels.
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.
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.
