Enjoyed for centuries, tea tends to be almost calorie-free, full of flavor, and it is generally among the healthiest of drink choices.
This article takes a look at 31 types of tea, their characteristics, and a summary of research into their health effects (where applicable).
Types of Tea
First of all, it’s important to note that true “tea” all comes from the same plant; Camellia sinensis.
The classification of this tea depends on how the plant’s tea leaves are prepared and processed.
There are five true teas;
- Black tea
- Green tea
- Oolong tea
- Pu-erh tea
- White tea
However, in modern times it is not only these traditional teas that enjoy popularity. There is also a wide range of herbal tea drinks made from flowers, grains, leaves, and even mushrooms.
Although they do not fit the true definition of “tea”, it is the name by which most people know them. For this reason, this article will cover various different tea varieties, including the five true teas.
1. Artichoke Tea
Artichoke tea is definitely one of the lesser-known tea varieties, but it does not involve the actual vegetable itself.
Instead, this particular tea features the dried leaves, roots, and stalk of the artichoke, and once steeped in boiling water results in an earthy and slightly bitter-tasting tea.
It is possible to see a range of health claims/hype about artichoke tea, but in truth, there is very little available human research on the drink. Thus, take any health claims with a heavy pinch of salt.
For tea lovers who enjoy trying new drinks, it is worth a try, but the best reason to drink it is simply that you enjoy the taste.
2. Barley Tea
Barley tea enjoys the most popularity in East Asia, and it’s a staple drink in China, Japan, and Korea.
In Japan, it goes by the name of ‘mugicha’ and Koreans call it ‘boricha’; many families drink it on a daily basis. The drink is made by toasting barley, and then boiling it for approximately 20 minutes.
Traditionally served cold with ice, it is especially popular as a summer drink and many people drink it like water.
The tea has recently enjoyed greater worldwide popularity, and it is easy to find online or in specialist stores.
Since the tea is a grain-infusion made with roasted barley, it is not a “true” tea. In regard to flavor, it tastes nutty, smoky, and slightly bitter. There is very limited research on the potential health effects of the drink.
See this full guide to barley tea for more information.
3. Black Tea
Made with the leaves of the Camellia sinensis plant, black tea is a true tea.
It’s also one of the most popular drinks in the world, particularly so in Great Britain and Ireland. In fact, Brits are thought to drink approximately 100 million cups of black tea every single day (1).
Due to the slightly bitter and astringent taste, many people enjoy adding a small amount of milk to black tea.
How Do Black and Green Teas Differ?
There are a few differences between green and black tea; the major one is that black tea requires a lengthier production process.
While tea leaves are heated almost immediately in the process of making green tea, the leaves for black tea are first dried in the sun.The withered leaves are then rolled to break their cells, which causes the leaves to oxidize quicker when they are (next) exposed to oxygen.
This exposure takes place in hot rooms to accelerate the oxidation of the leaves, and it turns them a dark red/brown color. At this point, the tea is heated to stop the oxidation.
Black tea is one of the most researched tea varieties, and much of the research is inconclusive. However, systematic reviews show that it may potentially have a small beneficial impact on blood pressure, type 2 diabetes risk, and the cholesterol profile (2, 3, 4).
See this guide to black tea for more information.
4. Brown Rice Tea
Brown rice tea originates in Korea and it simply involves steeping teabags that contain roasted grains of brown rice in boiling water.
There are also various types of green tea and brown rice tea combinations.
The tea is also popular in Japan, and it is relatively easy to find around the world. It should be possible to unearth the tea when visiting a local Asian grocery store, otherwise it is widely available from online stores.
Regarding its taste, the tea is earthy and tastes like toasted rice. Both the appearance and flavor of the tea are relatively ordinary, but the tea is enjoyable and refreshing to drink.
5. Chaga Tea
Many mushrooms have medicinal properties, but have you ever tried mushroom tea?
If not, you may want to look into Chaga mushroom tea.
This particular drink originates in the Russian/Siberian region, and the ‘Chaga’ mushroom is native to much of Northern and Eastern Europe, and Asia.
Chaga mushrooms are a type of fungus that grows on birch trees, and making them into tea simply involves boiling a piece of the dried mushroom. The tea does not really taste like you would expect a mushroom tea to taste, and it has a slightly bitter—but not unpleasant—taste.
It is a common daily drink in Siberia, and people believe it has important health and longevity benefits.
Is this belief backed by science?
Firstly, preliminary research into the potential benefits of the Chaga mushroom seems interesting.
Some research suggests that Chaga tea extract has anti-tumor properties and may inhibit oxidative DNA damage – in animal and cell studies (5, 6, 7).
However, these trials tend to use significantly higher concentrated extracts of the mushroom than what you will find in the actual tea. There is also no evidence that these effects occur in humans drinking the tea.
6. Chai Tea
Chai is a combination of black tea, steamed milk, and various Indian herbs and spices.
These spices typically include cinnamon, cardamom, cloves, and ginger, among others.
Depending on the specific tea and spices used, the flavor of chai tea can vary quite a lot. However, it is generally creamy, a little spicy, and it has a warming feeling while drinking it.
That said, the health properties of chai tea can be either positive or negative depending on where you drink it. While a traditional style chai tea is likely relatively healthy, some of the drinks we can find in cafes are more like desserts. For example, the Starbuck’s version comes loaded with 42 grams of sugar (grande size).
Chai tea will provide much of the same benefits as black tea, with the high polyphenol content of the spices perhaps being an added bonus.
7. Chamomile Tea
Chamomile tea comes from the edible flowers of the Matricaria chamomilla plant, otherwise known as chamomile.
This particular drink has a reputation for being a good bedtime beverage, and manufacturers claim it helps to relax our bodies. It is one of the most popular types of tea and it pairs a mild bitterness with a light, floral, and slightly sweet taste.
There have been many claims that drinking chamomile tea may be helpful for users with anxiety or insomnia. However, a recent systematic review and meta-analysis of human trials found that there was little evidence to support these claims (8).
That said, the tea is enjoyable to drink and it contains no caffeine, so it could be a good evening option for people.
8. Chrysanthemum Tea
Chrysanthemums are flowering plants that originate in East Asia, and we can mainly find them in China.
The flowers of this family of plants can vary in color, but they are edible and we can cultivate their leaves to make chrysanthemum tea.
Like all flower teas, chrysanthemum has a floral aroma alongside a light and slightly sweet flavor.
Traditionally seen as a herbal medicine in the East, people believe the drink has anti-inflammatory properties.
However, although the tea contains various polyphenols, there is very little research to confirm the purported benefits (9).
9. Dandelion Tea
For those of you with a garden, you can probably spot some dandelions from time to time.
They grow almost everywhere, but did you know you can eat them too?
Dandelions are edible, and dandelion salads and dandelion tea are both popular options. Tea made from dandelion leaves is very light and mild, with a slight floral taste.
However, there is also another dandelion drink known as ‘dandelion coffee’.
To make this particular “tea”, the production process calls for the roasting of the dandelion’s roots. Interestingly, this drink looks (and tastes) a little bit like coffee, and some people even use it as a coffee substitute.
There are claims that dandelion tea has digestive benefits, but there is no real research to support these (anecdotal) claims. The National Institutes of Health note that “there’s no compelling scientific evidence supporting the use of dandelion for any health condition” (10).
10. Essiac Tea
Essiac tea is a traditional drink of the Ojibwa, a North American Indian tribe also known as the Chippewa.
It has a slightly bitter, grassy kind of flavor.
Essiac tea has received media attention over the years due to people claiming that it can help to treat cancer. However, this is an evidence-free statement and should not be taken seriously.
These claims likely stem from cell (test tube) studies showing that large doses of essiac extracts can have strong antioxidant and potentially tumor-inhibiting properties – in cells (11, 12, 13).
However, the effects of concentrated extracts in cell studies are very different from what happens when humans drink the original tea. Most importantly, there are no human studies that suggest Essiac can be an effective cancer treatment (14).
11. Green Tea
Green tea originated in China where it has been popular for millennia.
While black tea is the popular choice in the Western world, green tea dominates the East, especially in Japan.
Green tea has a lighter and grassy, but refreshing taste. There are many different varieties of green tea too, some of which we will feature in this guide. The more popular kinds include sencha, genmaicha, and matcha.
There has been quite a lot of research looking at the potential effects of green tea on health. While the findings are somewhat mixed and inconsistent, recent systematic reviews of randomized controlled trials have suggested that green tea consumption may have some potential benefits.
A recent systematic review and meta-analysis of 27 human trials noted that green tea intake significantly lowered fasting glucose levels in the short term, but did not influence insulin. The researchers also noted that longer-term research is necessary on blood sugar control (15).
Further systematic review and meta-analyses of human trials have demonstrated green tea intake having a clear short-term effect on lowering diastolic and systolic blood pressure as well as LDL cholesterol. However, the researchers added that further longer-term research in diverse populations needs to confirm these findings (16, 17).
Also, a systematic review examined 17 randomized controlled trials on the effects of green tea on human markers of inflammation: this review found that there was no real effect on reducing inflammatory markers in people with existing low levels of inflammation (18).
In regard to this last study, it would be interesting to see what effects (if any) there would be for individuals with higher existing levels of inflammation – this is also something the researchers remarked on as an area for future investigation.
12. Hibiscus Tea
Otherwise known as Agua De Jamaica, hibiscus is a tea made from the dried petals of the roselle flower.
Resembling the flower’s color, hibiscus tea is dark blood-red, and it has a tart flavor and a flowery smell. Overall, the tea is enjoyable and refreshing to drink, but some people may find it slightly sour.
One of the reasons for the sour taste is the high acid content of hibiscus, with the tea containing malic, tartaric, citric, and ascorbic acids. In fact, the composition of hibiscus tea is 24% acidic (19, 20).
On the positive side, research appears to show a persistent benefit of hibiscus tea in regard to blood pressure. Several systematic reviews of human trials have all noted that the tea lowered diastolic and systolic blood pressure in individuals with high blood pressure (21, 22, 23).
See this full guide to hibiscus tea for more information.
13. Honeybush Tea
Honeybush tea is a lesser-known cousin to the popular rooibos (or “redbush”) tea.
Like its cousin, honeybush tea comes from South Africa where it is a popular drink. Honeybush is a fermented type of tea with a relatively strong and flavorful taste. Since the tea is also naturally caffeine-free, it can be an ideal evening drink for coffee/black tea lovers in a similar way to rooibos.
The flavor of honeybush and rooibos is quite similar, but honeybush has a slightly lighter and mildly sweet taste.
See this full guide to honeybush tea for more information.
14. Lemon balm Tea
Lemon balm tea is a refreshing drink made from the leaves of the lemon balm plant, also known by the scientific name Melissa officinalis.
Perhaps surprisingly from the name, lemon balm is a member of the mint family of plants, and it has a mild citrusy and slightly minty flavor. However, it does not taste anything like a sour lemon fruit, which is completely unrelated.
As a result, the tea features some good flavors and it is very refreshing and enjoyable to drink.
Some recent randomized controlled trials have suggested that consuming lemon balm is safe and that it may have slight benefits for blood sugar control and lowering LDL levels (24, 25).
15. Matcha Tea
Matcha is a kind of premium Japanese green tea.
To make the drink, shade-grown tea leaves are picked and then carefully ground into a fine powder.
Matcha is popular in Japan, where people tend to drink it in its pure state. The drink has a strong, bitter, and grassy taste.
However, (much of) the rest of the world mixes it with large amounts of sugar and steamed milk to make a green tea latte, in which case it has a sweet and milky taste. Unfortunately, drinking matcha in this way is worlds apart from the pure ground leaves in terms of health effects.
Promotional marketing for matcha tea often makes strong claims of health benefits and promotes the idea that matcha is more beneficial than regular green tea since drinkers consume the leaves.
But what health benefits does this tea actually provide? See this evidence-based guide to matcha tea for more information.
16. Moringa Tea
The Moringa (moringa oleifera) plant sometimes goes by the name of ‘horseradish tree’ and it is native to the Himalayas in northwest India.
The flowers, seeds, roots, and leaves are all edible, and some Asian cultures use the leaves for culinary purposes.
It is also possible to make tea from the leaves, and this comes in both dried and powdered forms. The tea itself has a light, grassy taste. It is quite mild and tastes somewhat similar to nettle tea.
Nutrient-wise, it is a rich source of several essential vitamins – particularly vitamin C and the B vitamins. Regarding the former, moringa leaves contain more than 200 mg of vitamin C per 100 grams, which is more than double the FDA’s daily value and more than a typical orange (26).
Marketing promotions often make a strong point about this vitamin C content. However, it is worth remembering that a typical serving of moringa tea is only a few grams – and nowhere near 100 grams.
There has been little research on moringa tea in humans, but a recent randomized trial found that moringa leaf had no effect on glycemic control (27).
17. Nettle Tea
Otherwise known as ‘stinging nettle tea’, the drink comes from the dried leaves of the urtica dioica plant (commonly referred to as ‘nettle’).
The taste of nettle is a light, grassy, and earthy tasting tea that has a mild, refreshing taste.
Research into the nutritional properties of nettle leaves has shown that they contain significant amounts of carotenoids and polyphenols (28).
However, once again, it is important to note that typical servings of tea are very small.
Interestingly, a systematic review of eight randomized controlled trials demonstrated that nettle leaf may have benefits for controlling fasting blood glucose, but further research is necessary to confirm these findings (29).
18. Oolong Tea
Oolong is another of the “true” teas and it comes from the leaves of the camellia sinensis plant.
But just what is it and how does it compare to green and black teas?
Firstly, oolong is a partially oxidized tea – it undergoes part of the same process as black teas.
Depending on the degree of leaf oxidation, it may taste closer to a green or black tea.
Oolong has a mixture of the potential benefits that green and black teas provide, and it contains a range of polyphenols found in both.
In terms of human research, a small study found that oolong tea might be effective for helping control blood glucose levels (30).
Additionally, the tea contains a wide range of polyphenols that may potentially help to reduce levels of oxidative stress (31).
19. Peppermint Tea
The dried leaves of the peppermint plant (mentha x piperita) make a bold, refreshing, and very minty tea.
It has a strong flavor and smell, so if you’re looking for a mild flavor, you won’t find it here, but peppermint is an enjoyable tea to drink.
There have been various small studies on this herbal tea, but there is no real significant research that shows a health benefit to the drink.
On the contrary, observational research has linked frequent consumption of peppermint tea to an increased risk of gastroesophageal reflux disease (GERD) in people with the condition (32).
20. Pu-erh Tea
Pu-erh tea (also pu’er) is one of the five true teas.
It is also a fermented drink, and similar to red wine or kombucha, pu-erh contains lots of live bacteria (33).
This is due to the production process; the processing of the leaves allows for microbial fermentation. As a result, the tea continues to age and change even after drying the leaves.
Pu-erh is a Chinese drink and it has the local name of ‘heicha’. Generally speaking, the taste is more bitter than standard tea, although it does become milder over time.
Traditionally, green pu-erh tea is the preferred choice and it has been around for centuries. However, making pu-erh from black tea has also ecome popular over the last few decades. Pu-erh has an equivalent caffeine content to whatever type of tea it is made from.
Randomized controlled trials demonstrate that pu-erh tea might potentially improve health markers in patients with metabolic syndrome (34, 35).
21. Pau d’arco Tea
Pau d’arco bark (otherwise known as taheebo) is a herb that comes from the pau d’arco tree.
These trees grow in the Amazon rainforest and the inner bark (taheebo) contains a variety of phytonutrients (36).
The tea is also rather tasty, and it has an interesting fruity/herby flavor that is hard to describe.
That said, be careful of unsubstantiated health claims, especially those relating to cancer. For instance, a quick search for pau d’arco brings up all kind of results suggesting it’s an alternative “cancer-fighting” therapy.
However, this borders on pseudoscience since there are no controlled studies in humans that provide evidence for this (37).
On this note, the Memorial Sloan Kettering Cancer Center notes that while laboratory (cell) studies show antibacterial and anticancer effects, “these effects have not been shown in humans” (38).
22. Raspberry Leaf Tea
Raspberry leaves (Rubus idaeus) grow on the raspberry plant and they have a long history of use.
These uses include various traditional herbal remedies and also as a refreshing tea.
Despite the name, the tea doesn’t really taste like raspberries, and the flavor is similar to other green/grassy teas. It is a popular drink and since it’s non-caffeinated, it’s a good match for those looking for a caffeine-free option.
Raspberry leaf has traditionally been a folk remedy for pregnancy, and it is believed to shorten the labor period.
However, there is limited research in this area for humans. Only one randomized trial has been undertaken, but this trial didn’t show any significant differences other than a very slight (9-minute) shortening of the second stage of labor (39).
23. Rooibos Tea
Rooibos (pronounced “roy-boss”) is one of the most popular types of tea.
Otherwise known as ‘red bush’, the tea originates in South Africa where it has been popular for centuries.
People generally consume the drink in a similar way to black tea; some prefer it “black” (red) and others add some milk and/or sugar.
Rooibos has an interesting taste, and it is equal measures of fruity, spicy, and nutty. For those sensitive to caffeine, rooibos has the benefit of being caffeine-free.
The tea contains a variety of phenolic compounds including flavanones and flavones (40).
24. Rose Tea
The rose (rosa) is a flower that grows all around the world. Rose tea comes from the dried petals of the flower.
These dried leaves can either make a pure tea or can combine with other herbs to make a rose-flavored drink.
In terms of taste, rose tastes light, sweet, and slightly tart. The mildly sour notes come from the rose petal’s citric and malic acid content.
Also, the dried petals contain various anthocyanins, the same class of polyphenol present in different types of berries (41).
25. Rosemary Tea
Rosemary isn’t only a herb for culinary purposes, but it is also a popular variety of herbal tea.
Making rosemary tea simply involves steeping approximately a teaspoon of rosemary leaves (fresh or dried) in hot water.
Once the tea has been brewing for several minutes, the color of the water will be light yellow and offer a mild-tasting tea. For a stronger brew, steeping the leaves for 5-10 minutes will provide a more flavorful rosemary tea.
Rosemary tea offers an earthy and mildly minty flavor, and it’s a tasty and relaxing herbal tea.
The drink also provides a rich source of polyphenols, which may potentially offer some benefits. However, there is no strong research from human trials on the potential effects of polyphenols in rosemary (42, 43).
26. Senna Tea
Senna belongs to a large group of flowering plants, possibly originating in Egypt.
The plant now grows throughout the world’s tropical regions, and senna tea is a semi-popular drink that may offer some potential benefits (and concerns).
Taste-wise, it is much more bitter than most of the other teas on this list.
Notably, the tea is approved by the FDA as a nonprescription laxative, and it contains active chemical compounds (anthraquinones) that can help to relieve occasional constipation (44).
However, it’s important to realize that senna is classed as a ‘stimulant laxative’. In other words, this means that it irritates the stomach lining to stimulate bowel movements.
By its very nature, this suggests we shouldn’t consume the tea in the long term. For one thing, animal studies show that long-term consumption of senna can potentially cause intestinal hyperplasia, which is a known risk factor for gastric cancer (45).
27. Sencha Tea
Sencha is a common variety of Japanese green tea.
Unlike matcha tea, sencha is grown under the sun, and we drink it by making an infusion from the whole tea leaves.
In Japan, it is the most popular kind of green tea, and it has a relatively mild flavor and a bold green color.
Like all green teas, sencha is full of polyphenols – especially catechins.
In fact, compared to other types of green tea, sencha contains the highest amount of these compounds (46).
28. Spearmint Tea
Sharing some commonalities with peppermint tea, spearmint has its own unique flavor notes.
Since spearmint leaves contain a much smaller amount of menthol than peppermint leaves, it imparts a slightly different taste (47).
For one thing, spearmint is a cooler and milder tea, and it doesn’t have the same strong ‘minty’ flavor. It has a subtle flavor which is quite refreshing.
Medically, spearmint tea has been used as a treatment for hirsutism in women. Hirsutism is a kind of hair growth that follows male hair patterns, such as growth on the face and chest.
A small randomized controlled trial shows a possibility that spearmint may help with this condition, but further, longer studies are necessary (48).
29. White Tea
If black is the strongest of the true teas, then white is the mildest.
It may also be a good option for those with caffeine sensitivities since it only contains around 25% as much caffeine as coffee.
White tea comes from the camellia sinensis plant and uses the freshest leaves available.
Firstly, tea leaves are picked at a younger age when making white tea.
Second, they don’t undergo processing such as rolling or oxidation, which leaves them with a mild and light taste.
Despite these differences, the nutritional profile and polyphenolic content of both green and white tea are similar (49).
For more information, see this complete guide to white tea.
30. Yerba Mate Tea
Yerba mate is a popular, traditional tea from South America, where it is regularly consumed. In recent times, it has been gaining popularity around the world too.
It is made from the leaves of a species of holly tree that grows in the South American rainforests.
Yerba mate has a deep and intense taste, and it is a caffeinated tea too. In fact, it contains around 80 mg of caffeine per cup, which is almost as much as coffee (50).
In addition to its pleasant taste, people enjoy yerba mate for its supposed energy and mood-boosting properties. A big part of these likely come from the caffeine content of the drink.
Some small randomized controlled trials have demonstrated that yerba mate decreased abdominal fat, reduced blood viscosity, and improved blood flow (51, 52).
However, higher-quality research with more consistent results is necessary to confirm such findings.
There has also been an identified concern with yerba mate consumption, which is that consuming the tea is associated with a higher risk of oral cancer (53).
That said, association does not equal causation, and it may be that South American populations consuming more yerba mate overlaps with tobacco and alcohol intake. Further, yerba mate is traditionally consumed at extremely hot temperatures, which may also be detrimental for oral health.
Future research should shed more light on this issue.
See this complete guide to yerba mate tea for more information.
31. Butterfly Pea Flower Tea
Butterfly pea flower tea is a unique traditional drink from South-East Asia, and it has a striking blue appearance.
Interestingly, the tea may have some benefits too, with studies suggesting that butterfly pea flower tea may potentially help to control blood glucose.
The tea is caffeine-free and the color is certainly an interesting talking point.
Which Tea is the Best?
The best tasting drink is a subjective opinion, so it will vary from person to person.
If you’re looking for healthy options, then most of the existing research has focused on the “true teas” – black, white, green, pu-erh, and oolong.
However, in truth, any single drink will only have minimal (if any) benefits, and as always: the overall dietary pattern is the most important thing.
10 thoughts on “31 Types of Tea: Profiles, Potential Benefits, Side Effects”
Thank you for the article.
I myself adore Oolong and Pu-erh the most, followed by scented white tea. The “true teas” for me. But I’m interested in trying the Butterfly pea flower tea since it does look rather appealing.
I prefer true teas too (alongside coffee) but Butterfly pea flower tea is quite fun to drink, and the color is rather impressive.
Very informative thank you.
I am becoming very partial to matcha. It has such a unique flavor with a decent amount of caffeine which, for some reason, keep my energy up without making me shaky (like coffee can.) It is also very easy on the stomach compared to coffee. If you are a “coffee person” I would suggest trying matcha. A very slight pinch of ginger added is also delicious. The only downside is price. It is more expensive than most other teams and can be hard to find. Asian (Japanese, Chinese, Korean, and occasionally Indian) stores usually carry it.
It is quite tasty, but I think it can be very different from brand to brand. I would agree that it is much “smoother” than coffee too. The Asian stores tend to be a good place to get it since the price is usually cheaper than say health stores or tea stores.
Very informative and interesting article, but one small quibble-“chai” means tea, so by saying “chai tea,” you said something twice!
Good point! Thanks for the comment.
I drink green tea (dragonwell) but find it hard to know if it’s the real deal or some fake tea. Do you know of any website that is honest about the products they sell? I am also interested in trying the matcha teas.
I would just look at the specific brand on a website like Amazon or Iherb – read through the customer reviews and see if people generally recommend the tea or not.
