  Every day, millions of consumers around the world wake up to a mug of steaming English breakfast, Darjeeling, or green tea. It’s a universal morning treat, an afternoon snack, and an after-dinner concoction—but little do many people know, this warming beverage provides many great health benefits as well.
  The four main varietals of tea leaves—black, green, white, and oolong—all come from the Camellia sinensis plant, but their similarities stop there. After the tea leaves are plucked from the plant, black tea is made from an oxidation process, while green teas are not oxidized at all, but rather are withered in hot air, steamed, or pan-fried. Oolongs are partly oxidized, and white teas are made from immature tea leaves that are picked shortly before the buds have opened fully.
  Green Tea
  Green tea is the most well known for its health benefits. Varieties include gunpowder and dragonwell, which are popular Chinese teas, and sencha, matcha, and genmaicha, which are widely consumed Japanese green teas. All of these different types offer a wide range of advantages.
  Cancer Prevention
  Studies have shown that drinking antioxidant-rich green tea every day can reduce the risk of many types of cancer. The antioxidant epigallocatechin gallette, known as EGCG, is highly effective at not only inhibiting the formation of cancer cells, but also killing them.
  Reduction of High Blood Pressure
  Green tea reduces high blood pressure, and its polyphenol and polysaccharide antioxidants are particularly good at lowering blood sugar.
  Immune System Boost
  If you think you’re getting sick, green tea will energize you and boost your immune system. It also helps to destroy free radicals, which cause aging, and protects the liver against toxins.
  Weight Loss Help
  Green tea aids in weight loss by stimulating metabolism.
  Antibacterial Protection
  Green tea has antibacterial properties and inhibits the spread of disease.
  Black Tea
  Black tea is the most processed of all the tea types. Unlike green tea, black tea is fully fermented, or oxidized, which accounts for its rich flavor. There are many types of black teas, each associated with a different region of the world, including Assam, Darjeeling, Ceylon, English breakfast, and Earl Grey. Black tea provides two primary health benefits.
  Cancer Prevention
  Black tea, like green tea, helps prevent cancer. An antioxidant compound called TF-2 that’s found in black tea kills cancer cells while preserving healthy cells. TF-2 also has anti-inflammatory properties.
  Heart Disease Prevention
  The flavonoids in black tea help to prevent heart attack and stroke.
  White Tea
  White tea, the least processed type of tea, is made from silver buds and immature, unopened leaves and then steamed and dried. White tea contains more of the antioxidant polyphenol, which is responsible for killing cancer cells, than any other type of tea. Types of white tea include silver needle, white peony, and snowbud.
  Infection Fighting
  White tea wards off infections, viruses, and bacteria.
  Tooth Support
  White tea is good for your chompers because it contains fluoride and prevents the growth of plaque.
  Oolong Tea
  Oolong falls between green and black tea on the processing spectrum; its leaves are semi-oxidized. There are hundreds of different types of oolongs cultivated in China’s Fujian and Guangdong Provinces and Taiwan, and they all promote good health.
  Weight Loss Help
  Oolong teas aid in weight loss by increasing metabolism and burning fat.
  Cholesterol Reduction
  Drinking oolong tea regularly helps reduce cholesterol.
  Skin and Tooth Support
  Oolong treats skin disorders, such as eczema and dermatitis. Also, like white tea, it’s concentrated with fluoride, so it helps prevent plaque buildup on teeth.
  Herbal Tea
  Although herbal teas are not derived from the leaves of the Camellia sinensis plant, some contain extremely potent health benefits.
  Roobis tea is similar to green tea in some ways; for example, the amount of polyphenols it contains is comparable to that of green tea, which means it has many anti-carcinogenic and anti-inflammatory properties.
  Mint tea is a great herbal remedy for digestion issues. It eases nausea and vomiting and helps treat irritable bowel syndrome. It’s also known for its stress-relieving properties.
  Ginger tea is another herbal tea that aids in digestion, especially by combating nausea; it also minimizes the symptoms of colds and allergies.
  Tea is a multitasking drink that’s packed with powerful antioxidants. It not only warms you up when the weather is cold outside but also treats you from the inside out with natural ingredients. Next time you reach for an espresso shot as a morning pick-me-up, replace it with a sweet Darjeeling from India or an earthy Earl Grey from England for similar results and many more health benefits.
