Black, green, oolong, pu-erh and white tea all come from the same plant, but their health benefits differ.

A tea only counts as “true tea” if it’s made from the Camellia sinensis plant, according to the Harvard T.H. Chan School of Public Health. A “tea” made from any other plant — including herbs, flowers, fruits, roots or spices — is actually called a “tisane” and can have widely different health benefits. In this article, we only cover the health benefits of true teas: black, green, oolong, pu-erh and white.

Tea Camellia Variety Caffeine Content per Cup Water Temperature Steeping Time Black Assamica 47 mg 203-212 F 3-5 min. Green Sinensis 25 - 29 mg 158-176 F 2-3 min. Oolong Sinensis 38 mg 176-194 F 2-3 min. Pu-Erh Assamica Varies 212 F 5 min. White Sinensis 15 mg 180-185 F 2 min.

Assam, Earl Grey and Bergamot are just a few of the many flavorful, hydrating varieties of black tea.

Many of the ingredients commonly found in chai — such as ginger, fennel and cinnamon — may help with digestion, according to the Pacific College of Health and Science. Others are rich in antioxidants.

Current research has only found associations, not direct cause-and-effect relationships, between drinking black tea and improved health outcomes. That said, links have been found between black tea and fewer broken bones, improved low blood pressure and lower rates of heart attacks, ovarian cancer, osteoporosis and Parkinson’s disease. Smelling the essential oil of Bergamot tea — a popular type of black tea — was linked to improved mood in one small study.

Green tea has unique health benefits because, unlike black tea, it isn't fermented.

Considering all the health benefits of green tea, you may wonder if it’s safe — or recommended — to give kids this drink, too. In low amounts, it’s “possibly safe,” according to C.S. Mott Children’s Hospital. That “possibly” is likely due to the tea’s caffeine content: It’s best to limit how much caffeine kids drink, per the Nemours Foundation.

A green tea latte is a variation of a traditional latte, which is made with espresso and steamed milk. This version swaps in green tea in place of the espresso. Then, steamed milk is added with a layer of foamed milk on top. A green tea latte offers all the health benefits associated with green tea. Plus, drinking milk provides several vitamins and nutrients. To limit saturated fat and calories, order your latte made with low-fat or skim milk. If your green tea latte is made with a cup of 1 percent milk, you’ll get 16 percent of your daily value (DV) of protein, as well as 15 percent DV of vitamin D and 23 percent of your DV of calcium, per the USDA. A cup of 1 percent milk also has 102 calories. Keep in mind that a green tea latte often includes syrup or added sweetener, so consider asking for less sugar or syrup. Or, make your own green tea latte to control the ingredients. Use green tea leaves or green tea bags.

Existing evidence supporting any direct cause-and-effect relationships between drinking green tea and improved health outcomes is preliminary. Rather, this research more often shows associations between green tea and better health, including links with less inflammation, lower rates of cognitive decline and heart disease, better control of type 2 diabetes and a longer lifespan. The evidence linking green tea and weight loss is limited, and green tea — or any caffeinated drink, for that matter — may actually worsen heartburn.

Oolong tea benefits have not been as rigorously studied as the perks of black or green tea, but the partially fermented leaves are thought to be anti-inflammatory.

Drinking tea every day is a good way to support a healthy routine and keep up with your hydration needs. Just avoid overdoing it on the caffeine. May Zhu, RDN, LDN, recommends keeping track of your daily caffeine intake and making sure it doesn’t exceed 400 milligrams. Keep in mind that caffeine can also be found in coffee, chocolate, sodas and energy drinks. Different types of tea will have varying amounts of caffeine, with the exception of herbal teas, which are caffeine-free. “The amount of time passed while steeping tea can also change the amount of caffeine in it, because the caffeine content will increase the longer you steep it,” Zhu says. This can potentially be problematic for people who are sensitive to caffeine, making it difficult for them to fall asleep at night or even worsening anxiety. Or, opt for herbal tea, which is caffeine-free.

Most of the studies examining the health benefits of oolong tea are small and were conducted more than a decade ago. Research on black and green tea is much more common because those teas are more popular. More research is needed on oolong tea specifically to better support preliminary findings including connections with diabetes management, heart health, weight loss and brain function.

Ripe, or fermented, pu-erh tea is often dried in a brick and rinsed before steeped.

Pu-erh tea is perhaps the least common true tea, and therefore one of the least studied. Preliminary animal and test-tube studies suggest pu-erh tea may be linked to lower cholesterol and reduced tumor cell growth, while studies in humans looking at weight loss and metabolic syndrome have focused on pu-erh tea extract, which offers a more concentrated version than tea. More research is needed in humans to understand what, if any, health benefits are directly attributable to pu-erh tea.

White tea is not fermented but still delivers antioxidants.

What little evidence there is supporting health benefits of white tea has mostly come from lab and animal studies. So far, there are connections with white tea and better heart health, stronger teeth, balanced blood sugar and weight loss. More research in humans is needed to back up these associations, let alone show cause-and-effect relationships.

Combining tea with honey can soothe a cough, but be mindful of how much honey you're using to keep added sugars in check.

Honey is considered an added sugar. The American Heart Association recommends that adults limit added sugars to between 6 to 9 teaspoons a day.

Not only will iced tea quench your thirst, but this beverage is naturally calorie-free (that changes, of course, if you add sugar or cream). If you replace high-calorie drinks such as soda or sweetened iced tea with unsweetened iced tea, you can cut your calories. For instance, while 12 ounces of sweetened iced tea has 119 calories, per the USDA, that same amount of unsweetened iced tea has zero calories. Plus, iced tea delivers all the same health benefits of hot tea, whether it’s green, black or any other variety.

It's important to keep in mind that health claims made by tea manufacturers are not evaluated by the FDA.

Ceylon tea is not a specific type of tea. Rather, the name refers to a geographic location: Ceylon tea comes from Sri Lanka, according to the Tea Exporters Association. This country was known as Ceylon by British colonists. Now, Sri Lanka is one of the top producers and exporters of tea in the world, according to the Tea Exporters Association. Ceylon tea is available in both green and black varieties and is linked to the same health benefits.
