Gardenias were originally found only in China and Japan, but today there are over 200 different species of gardenia, mostly hybrids, throughout the world. Gardenia fruit is used extensively in Traditional Chinese Medicine (TCM), where it is known as zhi zi. TCM uses gardenia primarily to promote calm, but it is also used to support bladder and urinary tract health.
Being a green tea, matcha does contain caffeine and in higher levels than other green teas. Because the entire leaf is used, matcha tea can contain nearly as much caffeine as a cup of coffee. However, caffeine release is believed to be slower because you are drinking the entire leaf. This slower release of caffeine reduces “caffeine jitters” that coffee or other teas can cause.
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.
Zen Buddhism and the Chinese methods of preparing powdered tea were brought to Japan in 1191 by the monk Eisai. In Japan it became an important item at Zen monasteries and from the fourteenth through to the sixteenth centuries was highly appreciated by members of the upper echelons of society. Although powdered tea has not been popular in China for some time, there is now a global resurgence in the consumption of Matcha tea, including in China.
There are also several harmful effects of green tea over-consumption that are possible. These include consuming tainted supplements marked as green tea extract, high caffeine consumption, consuming aluminum, and the effects of tea polyphenols on iron bioavailability. Green tea extracts should not be taken by patients suffering from renal failure, liver disease, heart conditions or major cardiovascular problems without supervision from a doctor. People sensitive to caffeine should be careful of their intake. Pregnant and breast-feeding women should drink no more than one or two cups per day, as some research shows that more caffeine than this amount may interfere with normal heart rhythms.
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.
One of the biggest buzz words in nutrition, antioxidants are naturally occurring chemical compounds that prevent aging and chronic diseases. Nowadays, a variety of fruits and vegetables are lauded for their antioxidant properties, leading to a host of products with all kinds of claims. But matcha is unparalleled in comparison. Firstly, matcha is packed with exponentially more antioxidants according to the latest innovation in antioxidant research.
Several varieties of green tea exist, which differ substantially based on the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest. Although there has been considerable research on the possible health effects of consuming green tea regularly, there is little evidence that drinking green tea has any effects on health.
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.
Still, there have been some interesting findings. A 2014 study looked at 25 randomized controlled trials on the link between tea and blood pressure and reported that when people drank tea—especially green tea—for 12 weeks, their blood pressure dropped significantly. A 2011 study reported that drinking green tea appeared to be linked with lower levels of bad LDL cholesterol, but more research is needed. Because matcha is a type of green tea, they may share similar benefits, but there’s not enough research to make that claim.
African red tea's naturally sweet taste makes it easy to keep your added sugar intake low. According to the American Heart Association, most Americans consume too much added sugar in their diet, which can lead to weight gain and obesity. The association recommends consuming no more than 6 to 9 teaspoons of added sugar a day. Added sugar, and especially drinks high in added sugar such as sodas, have no nutritional benefits whatsoever, unlike rooibos, which has a number of associated health benefits.
Researchers from the Netherlands confirmed in a recent study that two green tea compounds, L-theanine and caffeine, can significantly boost levels of attention and alertness, building on what is already known about the brain benefits of green tea. The drink is less likely to make you jittery and anxious than other energy-boosting drinks, because it contains lower levels of caffeine than other teas or coffee. In another study published in the American Journal of Clinical Nutrition, researchers discovered that drinking just one cup of green tea a day made people age 55 and older 38 percent less likely to experience a decline in their mental abilities. Drinking a second cup daily made them 54 percent less likely to show mental declines.
One-1/2 teaspoon serving of matcha, no more than once daily, is certainly a valuable addition to any diet, says Zeitlin. Like with another substance currently having a moment, turmeric, you can get your dose by eating or drinking it, though Zeitlin says drinking it as a tea, how it was initially intended, provides all the benefits without the added calories.
In China though, the term black tea or dark tea typically refers to a tea that we call Pu-erh in the United States. This tea is fermented anywhere between 2 weeks to two months and then aged for 2 months to 20+ years in order to create dark black leaves and a dark color to the brew. In this fermentation process the leaves are intentionally kept damp to encourage good microbes and bacteria to slowly oxidize and ferment the leaves. This is distinguished from red tea which typically only takes about 6-10 hours to oxidize. Pu-erh tea typically has a strong fermentation taste but high quality pu-erh should not taste overly earthy as this is a sign of low quality production techniques.
Cardiovascular diseases, which lump heart disease, stroke, and other diseases of the heart and blood vessels caused by atherosclerosis and hypertension (high blood pressure) into one category, are the most prevalent causes of death in the world. Studies show that green tea can improve some of the main risk factors for these diseases, which includes helping regulate total cholesterol, LDL cholesterol, and triglycerides. One method by which green tea might help: it significantly increases the antioxidant levels of your blood, protecting LDL cholesterol particles from oxidation—one of the causes of heart disease.
Green tea is processed using either artisanal or modern methods. Sun-drying, basket or charcoal firing, or pan-firing are common artisanal methods. Oven-drying, tumbling, or steaming are common modern methods. Processed green teas, known as aracha, are stored under low humidity refrigeration in 30- or 60-kg paper bags at 0–5 °C (32–41 °F). This aracha has yet to be refined at this stage, with a final firing taking place before blending, selection and packaging take place. The leaves in this state will be re-fired throughout the year as they are needed, giving the green teas a longer shelf-life and better flavor. The first flush tea of May will readily store in this fashion until the next year's harvest. After this re-drying process, each crude tea will be sifted and graded according to size. Finally, each lot will be blended according to the blending order by the tasters and packed for sale.
