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.
Studies in laboratory animals have found that green tea polyphenols inhibit the growth of esophageal cancer cells (in line with its anti-cancer properties). Other clinical studies have found that green tea offers protection against the development of esophageal cancer, particularly among women. However, one large-scale population-based clinical study found just the opposite: drinking green tea was associated with an increased risk of esophageal cancer, and the stronger and hotter the tea, the greater the risk. It seems that if the water is very hot, it can damage the esophagus and lead to long-term adverse consequences. So just make sure the tea you drink isn’t extremely hot.
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.
If you do choose to try a tea detox, the most important aspect isn't the kind of healthy tea you choose—it’s what else you eat: “Tea can only be medicinal and detoxifying if your diet isn’t taxing your system, which most American meals are guilty of,” says Lagano. In order to truly detoxify your body, cut processed and fried foods, and up your intake of fruits, vegetables, whole grains, lean proteins, and anti-inflammatory fats like avocados and almonds, says Villacorta. Once your diet is clean and gentle on your body, detoxifying teas can begin to enhance your natural organ function.
Since some of the bioactive compounds in green tea are anti-viral and anti-bacterial, in much the same way as green tea can kill bacteria in your mouth, it can also inhibit bacteria and viruses in your bloodstream and throughout the rest of your body. Similarly, green tea may inhibit viral and bacterial infection via your nasal passages. All this means that green tea may help prevent colds and the flu, and furthermore seems to be able to alleviate the symptoms of colds and the flu once you are sick.
“Specific detox teas offer added benefits in the additional ingredients,” says Villacorta. Herbs like lemongrass, ginger, dandelion, and milk thistle all contain properties said to support a healthy liver, one of those organs in charge of your natural detoxifying process. Ginger has also been proven to alleviate oxidative stress within the liver, which indirectly helps the organ perform its cleaning task more efficiently, he says.
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.
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.
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.
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.
Matcha is a high-grade green tea ground into powdered form. The green tea powder is whisked into hot water, instead of steeped, to form a frothy drink. The meditative act of preparing, presenting, and sipping matcha is the backbone of the Japanese tea ceremony. While matcha’s origins are ceremonial, the green tea powder is widely popular around the world in beverages like tea lattes or boba tea, and as a cooking ingredient in everything from ice cream to salad dressing.
As an additional benefit, L-Theanine may help memory and learning and ability all the while inhibiting any possible side-effects from caffeine, a natural component of green tea. Therefore, a bowl of matcha promotes concentration and clarity of mind without any of the nervous energy found in coffee. Try matcha as a pick-me-up for the afternoon or anytime you need extra focus.
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.
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.
Instead of being rolled, shaped and dried like traditional green tea leaves, the leaves destined to become Matcha are laid flat to dry. Grinding the leaves into Matcha is a slow process. If the mill stones overheat, the delicate green tea leaves might become damaged, which alters the flavor and taste. For reference, it takes about one hour to grind 30g of Matcha.

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.
