“Red tea” is the name the Chinese use for what we in the west call “black tea.” All true tea comes from the same plant, Camellia sinensis. The differences between types of tea result from different methods of processing the leaves. For green tea, the tea leaves are steamed, rolled and dried, a method that preserves the content of polyphenols, antioxidant compounds that confer the well-known health benefits of tea. For black tea, the leaves undergo a process of oxidation that changes the color and flavor and reduces the content of polyphenols. Oolong is intermediate between green and black tea – in color, flavor and polyphenol content.

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 study published in the journal Chinese Medicine, many of the beneficial biological effects of flavonoids on heart health seem to be due to cell-signaling effects that lower inflammation. (6) Not only do flavonoids have anti-inflammatory capabilities, but they’re also antithrombogenic, antidiabetic, anticancer and neuroprotective compounds.

Research shows that people who regularly drink green tea do not fall victim to common bacterial and viral infections as easily as those who do not add it to their diet. It boosts the immune system. The catechins, present in green tea, prevent bacteria and viruses from attaching themselves to cell walls in order to infect them. These catechins also counter the toxins released by microbes. This antimicrobial property also protects you from bad breath, dysentery, diarrhea, tooth decay, indigestion, flu, cough and cold, and colitis, all of which are caused by the microbial and fungal action.

The use of matcha in modern drinks has also spread to North American cafés, such as Starbucks, which introduced "Green Tea Lattes" and other matcha-flavoured drinks after matcha became successful in their Japanese store locations. As in Japan, it has become integrated into lattes, iced drinks, milkshakes, and smoothies.[14] A number of cafes have introduced lattes and iced drinks using matcha powder. It has also been incorporated into alcoholic beverages such as liqueurs and matcha green tea beers.[citation needed]

Matcha or maccha is a finely ground, bright emerald-green tea powder with the scientific name Camellia sinensis. It is prepared from a high-quality shade-grown leaf known as tencha. The tea bushes are sheltered to avoid the exposure of direct sunlight which reduces the pace of photosynthesis and slows down the growth of plants. This provides the leaves with a darker shade of green and stimulates the production of chlorophyll and amino acids.
The many well-researched health benefits of green tea make it a great beverage to include in your diet for the prevention and treatment of cancer, heart problems, cardiovascular diseases, high cholesterol levels, rheumatoid arthritis, infection, tooth decay, and many others. Green tea contains an antioxidant called epigallocatechin-3 gallate (EGCG), which is also helpful in treating a variety of diseases.
Grown under shade for three weeks prior to plucking, gyokuro is one of the most exclusive varieties of tea produced in Japan.[60] 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.[61]
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 has many health benefits. “It contains many nutrients, including antioxidants and anti-cancer and brain-healthy compounds,” Smith reminds us. One thing is for sure: regardless of whether or not you’ll shed pounds with green tea, drink it anyway. “All teas contain many healthful nutrients; it’s one of the healthier choices for a beverage!” Smith says.  

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.
I boil 8oz of water and put 2 tea bags in at night. If I feel very bloated when I wake up, I boil another 8oz of water and put 2 tea bags in. If you are trying to lose weight, I HIGHLY recommend drinking this tea at night. I feel amazing when I wake up in the morning. I was able to lose 60 pounds and I owe a lot of it to this tea for taking the extra bloating and the edge off. I really enjoy drinking it at night too because it soothes me, and I feel like it helps my body burn more fat as I sleep.
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.
"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.
I LOVE this matcha. I've tried the real Japanese matcha before (it was quite expensive) so I know the basic qualities of matcha powder. Let me tell you, this matcha is really good. It smells good with a vibrant green color as a matcha should be, and tastes good! Also, the bonus ebook is an interesting and helpful source for new recipes (I've never thought of putting matcha into pizza as a spice...).
The polyphenols in green tea, especially EGCG, have been shown to have a particularly powerful effect in supporting skin cells and cellular DNA in the presence of UV radiation from sunlight. May different clinical studies have shown EGCG to help skin defend against UVA and UVB rays. And because these polyphenols can accumulate in the skin, regularly drinking green tea or taking a green tea supplement with EGCG can act as all-day supplemental protection.
• In skin cancer studies, lab animals that were given green tea developed 1/10th as many tumors as animals that were given water. The EGCC in green tea inhibits the production of urokinase, an enzyme that cancer cells need in order to grow. It also seems to stimulate the process of programmed cell death, or apoptosis, in cancer cells. Pair your green tea with these 30 foods that help prevent cancer.
Most detox teas contain caffeine, probably because this stimulant may suppress appetite, trigger your digestive system to let go of waste, and help you shed water weight. A caffeine-induced energy boost may also lead to working out a little longer or harder than usual. However, too much caffeine can also be risky (see above) and interfere with getting enough sleep–and catching too few zzzs may ultimately undo the tea's weight-loss effects. In fact, too little shuteye has been shown to trigger excessive eating and weight gain and even slow metabolism, which can make it easier to gain weight even if you don't eat extra calories. A good rule of thumb, regardless of where your caffeine is coming from, is to nix it at least six hours before bed. And if you're trying to shed pounds, commit to making adequate sleep a top priority.
