Caffeine content: Matcha tea contains some amount of caffeine which may trigger allergic reactions. These reactions may include diarrhea, cardiac arrhythmia, and irritable bowel syndrome. Caffeine can also cause drug interactions basis the amount consumed. If you are new to matcha and are unaware of its sensitivities, then it is always advisable to ensure natural vigilance while trying it for the first time.
Basically, tea time may not be for you. I know we all want “quick results,” but instead a gradual change in diet is best. Since my last tea scare, I’ve actually gotten accustomed to simply eating better. Stuff like eliminating dairy has helped with my “fupa” (lower belly pudge), and overall bloat. Limiting my red meat intake has also helped. Leaner meats like turkey, chicken breast and egg whites have helped me keep inches off and feel more energized.

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.[23][22][26] 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.[23]

Green tea contains significant amounts of flavonoids, antioxidants that protect against heart disease by slowing the breakdown of LDL cholesterol, preventing blood clots, and improving blood vessel function. The benefits of green tea also include associations with lower cholesterol and lower rates of artery blockages. People who drink a cup or two a day have a 46 percent lower risk of developing narrowed arteries. Upping that to three cups a day lowers the risk of having a heart attack by 43 percent and of dying from a heart attack by 70 percent. It can even help prevent a second heart attack. In a study of 1,900 patients recovering from heart attacks at Beth Israel Deaconess Medical Center in Boston, the death rate among patients who drank at least two cups of tea a day was 44 percent lower than among non-tea drinkers.

Sejak (세작; 細雀; lit. "thin sparrow"), or dumul-cha (두물차; lit. "second flush tea"), is made of hand-picked leaves plucked after gogu (20–21 April) but before ipha (5–6 May).[77][78][79] The tea is also called jakseol (작설; 雀舌; lit. "sparrow tongue") as the tea leaves are plucked when they are about the size of a sparrow's tongue.[78] The ideal steeping temperature for sejak tea is 60–70 °C (140–158 °F).[80]
This tea is a rich source of antispasmodic agents, which can ease severe stomach cramps and abdominal pains. This is mainly due to the activation of K+ (potassium) ions in the body without antagonizing the activities of calcium, according to a report published in the Basic & Clinical Pharmacology & Toxicology. This can reduce the presence of hyperactivity in the gastrointestinal tract, thus preventing diarrhea and other intestinal issues.
In 2009, King’s College researchers found that epicatechin may protect brain cells through mechanisms unrelated to its antioxidant ability, as epicatechin is one of the few flavonoids that can cross the blood-brain barrier. The King’s College researchers reported that somehow epicatechin protects brain cells from the negative effects of beta-amyloid plaques, although the exact mechanism of how this works is still not entirely know.

One of the key components in Matcha is the amino acid L-theanine, which is found almost exclusively in shade-grown green teas like Matcha. When L-theanine is combined with the natural caffeine in tea, it metabolizes more slowly, releasing the caffeine over a longer period of time and providing a stable three to six hour long energy boost (versus coffee caffeine at an hour to an hour and a half).
Just have a cup of hot green tea after some rigorous exercise and you will be ready for a few more sets in no time. Furthermore, it effectively counters muscular pain due to overexertion of muscles. Although green tea isn’t widely consumed due to the presence of energy drinks in the market, if you visit Japan and China, you will see that green tea is the premier beverage used by practitioners of martial arts and various other sports. 

Tea seeds were first brought to Japan in the early 9th century by the Buddhist monks Saicho and Kukai. During the Heian period (794–1185), Emperor Saga introduced the practice of drinking tea to the imperial family. The Zen Buddhist priest Eisai (1141–1215), founder of the Rinzai school of Buddhism, brought tea seeds from China to plant in various places in Japan. Eisai advocated that all people, not just Buddhist monks and the elite, drink tea for its health benefits.[50]

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.

Rooibos tea or red tea is an herbal beverage, with medicinal properties, that is acquired from the Aspalathus linearis bush plant found in South Africa. According to the South African Rooibos Council, rooibos is not a true tea, but an herb. The fermented tea is red in color. The health benefits of red rooibos tea are abundant. It is popular due to its great taste and unique color that comes along with health benefits.
“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.

Red tea is also known as Black tea in Asia. White, green, oolong, and black teas all come from the same plant, the Camellia sinensis. The difference in their flavor lays on the drying processes of their leaves, which determine how oxidized the final product is. Red tea is made of completely oxidized tea leaves, resulting in a darker and aromatic tea drink.

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.

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.

The important thing to note here is that what we refer to as red tea in our shop and what is called red tea in China would be referred to as black tea in most other countries. The distinction in color depends on whether you are talking about the color of the leaves or the color of the brew. The color of the brew is typically a beautiful amber, red color thus leading to the name “red tea”. The color of the leaves though are typically dark black, thus leading to the name “black tea”. Thus the terms can be used interchangeably. Red tea is oxidized/fermented for about 6-10 hours until the leaves turn an amber/black color and then they are dried to stop the oxidation process.

Detox teas that combine caffeine with diuretics can trigger the loss of water weight. Just two cups of water weighs one pound on a scale, so shedding fluid can make you look and feel lighter–even if you haven't lost an ounce of body fat. Detox teas can also trigger a laxative effect, which causes your body to eliminate waste from your GI tract, another result that can make your stomach flatter, and allow you to feel lighter, even if your lean-to-fat ratio remains exactly the same. If this quick-fix effect gives you the confidence boost and motivation you need to start eating healthier and working out–the real keys to getting healthy and lean–terrific (assuming the teas are even safe to drink–see below). Just remember: If you go back to your former less-than-stellar eating or exercise habits, or stop drinking the tea, you can gain the weight right back just as quick as you dropped it.
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) 

Word began to spread and rooibos tea was suddenly being put up against a number of health issues to see what benefits it showers. 50 years later, the world knows all about this powerful little herb! The exact mechanism by which it soothes colic and stomach pain is unknown, but the anti-inflammatory properties of the herb are most likely responsible.
