Rooibos is being heavily hyped by producers and distributors as a new health beverage. Unlike true “tea,” it is caffeine-free and low in tannins. It contains minimal amounts of calcium, potassium, iron, zinc, magnesium and much less fluoride than found in real teas. Studies have shown that Rooibos does contain antioxidants and therefore might have some of the health benefits of green tea, but very little research has confirmed this. I found only 17 scientific studies of Rooibos compared to more than 1,000 on green tea. So far, none suggest that Rooibos is the health equivalent of green tea.
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.

Matcha tea rich in EGCG  helps fight various bacterial, viral, and fungal infections. According to a research study,  EGCG binds to the lipid membrane and exerts inhibitory action against the growth of various human pathogens. These include influenza A virus, hepatitis B, and C virus, herpes virus, adenovirus Staphylococcus aureus bacteria, and Candida albicans yeast.
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.
This is yet another powerful benefit of green tea. Astringent substances trigger contractions in muscles and tissues while toning up muscles and skin. Even if you do not wish to drink green tea, a simple, daily mouthwash with it can cause sufficient contraction in your gums to keep them firm and tight on the teeth, thus preventing loosening and loss of teeth. You can also wash your hair with green tea and feel it grow stronger and healthier every day.
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.
Both nutritionists we spoke to agree that drinking tea when you wake up and before bed can help your system rev up and calm down, depending on which variety you choose. If you’re a tea fanatic, work in a few cups throughout the day: Unless you’re sensitive to caffeine, you can probably handle five to seven cups a day without any negative side effects, says Lagano.

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.

Simply stated, tea detoxes claim to rid your body of the toxins caused by a build-up of unhealthy foods, alcohol, and a number of other things your body doesn’t use to properly function. The teas are mixtures of various ingredients (green tea, matcha, oolong, goji berries, etc.), all with impressive health benefits, and the point is that the tea provides you with sustainable energy while subsequently eliminating toxins from your body. Most teas are to be consumed at least once a day, and some are accompanied by an additional colon cleanser.
"It's only in the last 10 year that Western science has tried to look at antioxidant activities of tea," says Dave Ringer, PhD, scientific program director at the ACS. "It's a young science. Generally, it is felt that tea can inhibit the initiation of cancer and delay its progression in animal studies. But we don't really have large well-controlled epidemiological studies to look at this yet [in humans], because you need to correct for the effects of other dietary components."
The polyphenols in green tea, which include multiple subcategories of polyphenols like flavonoids and catechins, can reduce the formation of free radicals in the body, protecting cells, molecules, and other structures from damage. One of the most active and powerful antioxidant polyphenols in green tea is epigallocatechin-3-gallate (EGCG). EGCG has been studied to treat a wide variety of diseases and may be one of the main reasons green tea has such powerful medicinal properties. Beyond EGCG, other polyphenol catechins in green tea include catechin, gallocatechin, epicatechin, epigallocatechin, and epicatechin gallate.
Japanese green teas have a thin, needle-like shape and a rich, dark green color. Unlike Chinese teas, most Japanese teas are produced by steaming rather than pan firing. This produces their characteristic color, and creates a sweeter, more grassy flavor. A mechanical rolling/drying process then dries the tea leaves into their final shape.[54] The liquor of steamed Japanese tea tends to be cloudy due to the higher quantity of dissolved solids.[56]

Shade grown: All matcha is made from shade-grown tea leaves—a labor-intensive process where tea bushes are protected from the sun and light is filtered to the bushes in a very controlled manor. Shading boosts the chlorophyll production in the plant, giving the leaves a rich green color. The lack of sun reduces the plant’s photosynthesis of the leaves, which in turn alters the naturally occurring levels of caffeine, flavanols, sugars, antioxidants, and theanine. By controlling the sun exposure, tea producers can significantly alter the chemical make-up and flavor of the final tea leaves.
