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.
Unlike traditional green tea, matcha preparation involves covering the tea plants with shade cloths before they’re harvested. This triggers the growth of leaves with better flavor and texture, which are hand selected, steamed briefly to stop fermentation, then dried and aged in cold storage, which deepens the flavor. The dried leaves are then stone-ground into a fine powder.
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.
Ginger Root, the underground stem, or rhizome, of the plant Zingiber officinale, has been used in many herbal traditions since ancient times. In Ayurveda, Ginger is known as the wonder herb, and it's no wonder, since Ayurveda employs Ginger for a wide variety of health applications, including digestive support. Historically, Ginger Root was also one of the most respected herbs for supporting joint health. Additionally, Ginger Root has been traditionally used to support healthy peripheral circulation; and can aid in warming up cold hands and feet, and will also promote sweating when needed. 

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.
The risks associated with green tea are the same as those associated with any other kind of tea (common black tea, White Tea etc.) and are primarily due to the content of caffeine and tannin. The contraindications may vary with the percentage of caffeine and tannins in it. Most people might be familiar with these adversities, but it is still important to review and summarize the components responsible, as well as the associated risks.
Apart from causing premature aging, free radicals are also responsible for causing certain types of cancer. The catechins present in green tea neutralize these free radicals, prevent the formation of carcinogens like nitrosamines and reduce the risk of cancer for people who regularly consume it. Green tea is now being clinically used and prescribed as a home remedy to aid in the prevention of cancer, particularly for those patients at high risk for cancer in the colon, rectum, pancreas, and intestines.
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.
Grown under shade for three weeks prior to plucking, gyokuro is one of the most exclusive varieties of tea produced in Japan.[60] The shading technique imparts a sweeter flavor, and produces a particularly rich color thanks to the higher amounts of chlorophyll in the shaded leaf. Gyokuro tea is associated with the Uji region, the first tea-growing region in Japan. It is often made using smaller-leaf cultivars of the tea plant.[61]
