Even organically grown green teas have been shown to contain lead, which is absorbed by the plant from the environment, particularly tea grown in China. When traditional green tea is steeped, about 90% of the lead stays in the leaf, which is discarded. With matcha, since the whole leaf is consumed, you will ingest more lead. One independent group, ConsumerLab.com, which tested teas, estimates that a cup of matcha may contain as much as 30 times more lead than a cup of green tea. Therefore, they recommend drinking no more than one cup daily, and not serving it to children.
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.
The detox period lasts for about 30 days, and most companies recommend taking a significant break (around six weeks) between detox sessions if you plan to do it more than once. Many detox tea companies are also quick to note — in small print, of course — that their teas are not suitable meal replacements and are meant to be used in conjunction with healthy eating and regular exercise.
In response, the governor of Shizuoka Prefecture, Heita Kawakatsu, stated: "there is absolutely no problem when they [people] drink them because it will be diluted to about 10 becquerels per kilogram when they steep them even if the leaves have 1,000 becquerels per kilogram;" a statement backed by tests done in Shizuoka. Japanese Minister for Consumer Affairs and Food Safety Renhō stated on 3 June 2011 that "there are cases in which aracha [whole leaves of Japanese green tea] are sold as furikake [condiments sprinkled on rice] and so on and they are eaten as they are, therefore we think that it is important to inspect tea leaves including aracha from the viewpoint of consumers' safety."
One study that was published in the February 2010 issue of the Journal of Agricultural and Food Chemistry investigated the effects of catechins on eye diseases and found that consuming more catechins may help protect the eyes from oxidative damage and vision loss. Scientists involved in the study found evidence that catechins can pass from the digestive tract of rodents to the tissues of their eyes and reduce oxidative stress for up to 20 hours after ingestion.

But when it comes to detoxification, tea alone isn’t enough for the job. “No one food, herb, or remedy has the ability to cure ailments or disease, nor does it have the ability to ‘detox’ the body,” says Manuel Villacorta, R.D, author of Whole Body Reboot: The Peruvian Superfoods Diet to Detoxify, Energize, and Supercharge Fat Loss. (This is also why you might want to hold off before trying to detox by drinking activated charcoal.)
Gyokurocha: In this variety, the tea leaves are plucked from the tip of the branches. When brewed, the color is clear green. Being picked from the tip, this variety has the best taste and fragrance, and this variety is also considered the best in terms of health. Furthermore, it is less bitter, as it contains lesser tannin and caffeine since the plucked leaves are younger and still budding. The only drawback to gyokurocha is the high cost, but as we all know, truly high-quality solutions for health never come cheap!

We’re wary of any trend that involves detoxing with just a drink. By now, we’re all pretty aware that liquid diets can’t sustain our active bodies for very long, and most of the drinks celebrities swear by have little actual detoxifying effects. But a teatox, or tea detox or tea cleanse, is a gentler approach to the whole idea, namely because it involves adding a few herbal cups to your existing, healthy diet—instead of replacing meals entirely.
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.

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.
