Maturitas (Review). 73 (4): 280–7. doi:10.1016/j.maturitas.2012.08.008. PMID 22986087. In conclusion, whilst there is a considerable body of evidence for green tea with some of it suggesting a positive effect, it is difficult to be definitive as to its health benefits.
So-called "detox" teas have been popular for years, primarily among people who frequent health-food stores, or consult with alternative practitioners. These days, though, they've become big business, and a handful of celebrities are touting their weight-loss benefits on social media. In a way, detox teas have become the liquid version of waist trainers–the before and after results are often dramatic, and their celeb backing generates buzz, but you may be wondering: Do they really work, and are they safe? Before you plunk down your hard-earned money and start sipping, here are five things you should know.
Rooibos contains polyphenols that have anti-inflammatory, antiviral, and antimutagenic qualities. Polyphenols are organic chemicals that are often praised for their antioxidant capabilities. Studies suggest that regularly drinking organic red rooibos tea provides the liver with potent antioxidants, helping the organ to improve detoxification. Antioxidants act as scavengers of free radicals throughout the body, which are detrimental byproducts of cell metabolism that can cause cancer and heart diseases. Aspalathin and nothofagin are two other vital antioxidants that rooibos tea contains, making it a great beverage to boost your immune system and protect your body against all types of diseases.
It depends not only on the processing method the tea producers use, but also on the cultivation practices the tea growers use. What time of year is the tea plucked? How is the plant pruned? What parts of the plant are plucked? Are the plants treated with chemicals or are they organically grown? What kind of heat is applied to the tea leaves to stop oxidation? How are the tea leaves shaped, rolled and dried? Are the leaves left whole or cut in smaller pieces?
The many well-researched health benefits of green tea make it a great beverage to include in your diet for the prevention and treatment of cancer, heart problems, cardiovascular diseases, high cholesterol levels, rheumatoid arthritis, infection, tooth decay, and many others. Green tea contains an antioxidant called epigallocatechin-3 gallate (EGCG), which is also helpful in treating a variety of diseases.
Ceremonial grade: This is the highest quality used mainly in tea ceremonies and Buddhist temples. This is stone-ground into a powder by granite stone mills. It is high-quality and expensive (~$100–140 for 100g). The unschooled drinker is unlikely to notice a large difference between Ceremonial and Premium grade. Ceremonial is characterized by subtle tones of "umami".
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.

Once on the toilet, I continued to be hit with these cramps as my body began to get cold. My hands and feet became clammy and I was shaking. I had goosebumps allover. I tried to use the restroom but my heart did this thing where I could feel it flutter. Everything around me got quiet, deafening, and all I could hear was my heartbeat. It was an out-of-body experience. I felt hollow, chilly, still, and petrified.
Observational studies found a minor correlation between daily consumption of green tea and a 5% lower risk of death from cardiovascular disease. In a 2015 meta-analysis of such observational studies, an increase in one cup of green tea per day was correlated with slightly lower risk of death from cardiovascular causes. Green tea consumption may be correlated with a reduced risk of stroke. Meta-analyses of randomized controlled trials found that green tea consumption for 3–6 months may produce small reductions (about 2–3 mm Hg each) in systolic and diastolic blood pressures. A separate systematic review and meta-analysis of randomized controlled trials found that consumption of 5-6 cups of green tea per day was associated with a small reduction in systolic blood pressure (2 mmHg), but did not lead to a significant difference in diastolic blood pressure.
