Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects. In 2011, a panel of scientists published a report on the claims for health effects at the request of the European Commission: in general they found that the claims made for green tea were not supported by sufficient scientific evidence. Although green tea may enhance mental alertness due to its caffeine content, there is only weak, inconclusive evidence that regular consumption of green tea affects the risk of cancer or cardiovascular diseases, and there is no evidence that it benefits weight loss.
Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.
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.
Does green tea really burn fat, and will drinking green tea help you lose more weight? According to some research findings, consuming antioxidants found in green tea, especially catechins and the compound called EGCG, may promote metabolic health and modestly prevent weight gain. When 11 studies and articles were included in one 2009 meta-analysis that was published in the International Journal of Obesity, researchers found that “catechins or an epigallocatechin gallate (EGCG)-caffeine mixture have a small positive effect on weight loss and weight maintenance.” (12)
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.
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.
A study suggests that theanine found in matcha tea acts as a neurotransmitter. It exerts a calming effect on the brain without causing any drowsiness. This soothing effect helped the Buddhist monks in maintaining deep concentration during their meditation sessions and was the main reason behind its popularity. Another study has revealed the anti-stress effects of theanine present in this tea, which assists in reducing the physiological and psychological stress responses by inhibiting the neuron excitation. Matcha tea is also believed to boost memory and concentration.
Rooibos, also known as African red bush, grows near Cape Town, in the Cederberg region. To produce red tea, manufacturers harvest and chop the needle-shaped green leaves of the rooibos plants, which are then dampened and fermented for 12 hours. Once fermented, the leaves oxidize, turning red before they are dried and sold as loose or bagged tea. When steeped in hot water, the resulting liquid has a reddish-amber hue and an earthy taste that isn't bitter because it's low in tannins. You can drink it alone or with milk, sugar, honey or lemon. This somewhat astringent tea is rich in antioxidants, including quercetin, aspalathin and nothofagin, all of which have anti-inflammatory and calming properties, according to the "Journal of Agricultural and Food Chemistry," published in July 2009.
Beautiful Fall day here in Dallas 😎Getting ready for a walk with the Ellie Girl and my @teamiblends of course. Love taking my tumbler on-the-go.

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?
To cut down on aches and pains, try to sip four cups of green tea a day. The tea contains quercetin, a chemical compound that acts as a powerful anti-inflammatory and antioxidant. In a recent study conducted at Case Western Reserve University, researchers gave mice the equivalent of four cups of green tea a day, then gave them a substance that would normally produce rheumatoid arthritis. The tea-drinking mice were far less likely to develop arthritis than mice that drank water. According to the Iowa Women’s Health Study, women who drank more than three cups of tea a day were 60 percent less likely to develop rheumatoid arthritis than non tea drinkers. Other research has found that tea’s polyphenols—antioxidant properties—are also anti-inflammatory and improve arthritis-related immune responses. Did you know other teas also act as natural home remedies for arthritis pain?
One thing to watch out for in detox teas, though, is a common ingredient—and herbal laxative—senna. “One part of detoxing is the cleansing of the intestines, and senna aids this process,” he explains. While it can be helpful as a night-time drink short-term, taking senna for too long can cause vomiting, diarrhea, electrolyte imbalance, and dehydration. If you feel stopped up, incorporate a senna tea for a few nights (Villacorta recommends Traditional Medicinals Organic Smooth Move). But stick to senna-free varieties for your habitual cup.
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.
Drinking green tea or taking green tea supplements decreases the blood concentration of total cholesterol (about 3–7 mg/dL), LDL cholesterol (about 2 mg/dL), and does not affect the concentration of HDL cholesterol or triglycerides. A 2013 Cochrane meta-analysis of longer-term randomized controlled trials (>3 months duration) concluded that green tea consumption lowers total and LDL cholesterol concentrations in the blood.
In 1994, Burke International registered the name "Rooibos" with the US Patent and Trademark Office, thus establishing a monopoly on the name in the United States at a time when it was virtually unknown there. When the plant later entered more widespread use, Burke demanded that companies either pay fees for use of the name, or cease its use. In 2005, the American Herbal Products Association and a number of import companies succeeded in defeating the trademark through petitions and lawsuits; after losing one of the cases, Burke surrendered the name to the public domain.
