10 Wonderful Benefits of Oolong Tea

Health benefits of oolong tea include the reduction of chronic health conditions such as heart diseases, inflammatory disorders, and high cholesterol levels while providing vital antioxidants, promoting superior bone structure, robust skin, and good dental health. Oolong tea is fragrant with a fruity flavor and a pleasant aroma. Despite its caffeine content, it is still a relaxing drink.

The health benefits of oolong tea are doubled because of the combined qualities of black tea and green tea. According to the Tea Association of the United States, this tea falls somewhere between green and black teas, as its leaves are partially oxidized. There are numerous kinds of tea in this world, but oolong tea is one of the most beneficial.

The origin of oolong tea dates back almost 400 years when it found wide usage in China. It is a semi-green fermented tea, but the fermentation process is halted as soon as the tea leaves start to change their color.

Oolong Tea Nutrition Facts

This tea is a natural gift that is rich in antioxidants. It also contains vital vitamins and minerals such as calcium, manganese, copper, carotin, selenium, and potassium, as well as vitamin A, B, C, E, and vitamin K. Additionally, it contains folic acid, niacinamide, and other detoxifying alkaloids. It is developed in semi-fermented processing, which provides the tea with numerous polyphenolic compounds and adds even more valuable health benefits. Oolong tea also contains caffeine, theophylline, and theobromine (which are similar to caffeine) that on consumption, may stimulate the nervous system.

Health Benefits of Oolong Tea

With so many health benefits and a relaxing effect it has for you, the inclusion of this tea in your diet is a great idea. Let’s have a look at the incredible benefits of oolong tea.

Manages Weight

The polyphenolic compound found in oolong tea is very effective in controlling the metabolism of the fat in the body and reducing obesity. It activates certain enzymes, thereby enhancing the functions of fat cells in the body and a daily consumption of this tea can reduce obesity. In one study, mice that were given polyphenols in addition to a high-fat and high-sugar diet still showed a decline in overall body weight and fat index. Some earlier studies actually showed that the caffeine content was an active ingredient for weight loss, but it now appears to be mainly due to the polyphenols. Apparently, the active components in oolong tea make fat work for you.

Removes Harmful Free Radicals

The polyphenolic compound in oolong tea is also responsible for the removal of free radicals in our body because it functions as an antioxidant and stimulates the behavior of these compounds in the body. Therefore, consuming daily doses of oolong tea can help people against the potential harm that these free-moving cells often pose to the body, including cancer, atherosclerosis, stroke, rheumatoid arthritis, neurodegeneration, and diabetes.

Prevents Ovarian Cancer

Oolong tea is rich in anti-cancer properties. And drinking it helps to significantly lower risk of developing ovarian cancer in women.

Skin Care

According to scientific experiments, patients diagnosed with eczema can benefit from drinking 3 cups of oolong tea throughout the day. The beneficial results of this tea could be seen in less than a week in these patients who will show remarkable improvement in recovering from skin problems. In a 2001 study, 54% of test subjects were found to show positive, long-lasting results in terms of skin conditions after 6 months of daily intake of oolong tea.

Treats Atopic Dermatitis

Although the active mechanism has not been pinpointed exactly, many believe that the polyphenols present in oolong tea also work as anti-allergenic compounds, thereby relieving irritation and chronic skin problems, known as atopic dermatitis.

Improves Bone Health

The antioxidants present in oolong tea protect teeth against decay, strengthen the bone structure, prevent osteoporosis, and promote normal, healthy growth of the human body. A number of studies analyzed the long-term effects of drinking this tea, particularly on bone mineral density (BMD). It showed that people who consistently drank black or oolong tea for more than 10 years were less likely to lose their bone mineral density over that span of time. It is thought that some of the components in this tea actually stimulate the retention of minerals from other food that we consume.

Controls Diabetes

Oolong tea is used as an herbal brew for treating type-2 diabetic disorders and as an addition to other supplementary drugs for treating the disease. It regulates the amount of blood sugar and insulin in the bloodstream, so the dangerous dips and spikes in blood sugar that can be disastrous for diabetic patients are reduced. A 2003 study showed that when combined with regular hyperglycemic drugs, oolong tea further balanced the blood sugar levels and prevented the sudden drops in almost all of the test subjects.

Prevents Cancer

It is a well-known fact that tea drinkers have a lower risk of getting skin cancer. Moreover, the polyphenolic compound in oolong tea promotes apoptosis in case of cancerous cell growth in the stomach. This polyphenolic extract also acts as a chemo-preventive instrument against the development of other cancers. The compounds stifle the activation of carcinogenic cells, prevent the formation of N-nitroso compounds and trap genotoxic agents before they can become effective.

Manages Stress

In a detailed study conducted at the Osaka Institute for Health Care Science in Japan, the experimental mice in which oolong tea was ingested, showed a remarkable improvement in the stress levels by 10 to 18 %. The natural polyphenols in oolong tea were cited as the main cause of it being a stress-buster. Also, the L-theanine found in tea leaves is an amino acid that blocks L-glutamic acid to glutamate receptors in the brain. This would normally cause cortical neuron excitement, which leads to an increased cognitive activity and neural stress responses. Since this amino acid binds to those sites, excitation doesn’t occur, and stress decreases because you are able to keep your mind at rest.

Improves Mental Health

Health benefits of oolong tea include improved mental performance and alertness. Regular intake of caffeine-rich oolong tea may help in improving mental performance and maintaining alertness throughout the day.

Word of Caution: Despite all of these important effects, it is important to remember that oolong tea tends to be high in caffeine, which is not the healthiest component of this beneficial beverage. Caffeine treats many people differently, but some of the side effects of excess caffeine are anxiousness, headache, sleeplessness, diarrhea, heartburn, irregular heartbeat, and confusion.

More serious conditions that can be exacerbated by too much caffeine intake are diabetes, heart conditions, anxiety disorder, irritable bowel syndrome, and high blood pressure. Also, drinking too much oolong tea can actually sweep out excess calcium that your body is processing. For patients with osteoporosis, this can speed up bone degradation, even though other elements of oolong tea are helpful for this condition. It is best to use it as a preventive method for bone problems, rather than a treatment.

In other words, drink several cups of oolong tea a day, because it might be the best kind of tea for improving your health and is also a delicious and relaxing treat. That being said, be aware that caffeine is a powerful chemical, and monitor your body’s response to this change in your diet, just as you should with all new foods and nutritional sources.

Are the benefits of the tea affected if the tea is mixed with soy milk? The soy milk I drink is organic, with nothing added. I drink this every day - half oolong tea and chai, and soy milk. It's delicious and makes me happy every day.

White Tea Cancer Reaearch has some great information on loose leaf white tea which I believe is much healthier than Oolong Tea. I usually drink a variety of loose leaf white teas everyday and some times mix loose leaf white with loose leaf Osmanthus Oolong and occasionally
Pu-erh Tea. I keep stressing 'loose leaf' because the bags you get at the store do not have the nutritional value as loose leaf. And white tea tastes naturally sweet. You never want to mix anything with tea like milk or cream because again it effects the nutritional compounds. And never pour boiling water over tea, always 170-190 degrees.

I just brew it and drink it without lemon or sweetener. I think tea is better that way

I have been using one bag of oolong and one bag of green tea....is this a good combination?

I bought the Twinings China Oolong Tea at a local grocer. Is it as efficient?

Tangerine Whitney

Diahria daily I hope this ends soon I'm only drinking one cup a day..

I Searched in Local stores and mall in India I could not find Oolong Tea.

I found online Chinese Tieguanyin oolong tea 100 grams for 645/-.
Is the price reasonable or High.

It's high. Uncle Lee sells oolong tea in Walmart for 2.98 for 18 bags.

To Vishal..try Asian supermarket in your area.. Price for oolong tea in my area goes for $1.89 for a box of 20 teabags.


I make a gallon with stevia (0 sugar) and put it in the fridge to drink several glasses through out the day. Triglycerides were 221 in Dec 2016/ March 2016 down to 98. The high Triglycerides levels are from genetics and not diet. Hope this helps some people.

Any pluses from the tea are quickly neutralized with the Stevia. Do the research. Artificial sweeteners tend to change the bacteria in the gut and those using artificial sweeteners have a tendency to become insulin resistant despite it being "sugar free".


I have been using Stevia for over 5 years. I weaned myself off of a severe Cola habit, and cured myself of diabetes in the process. Stevia is NOT an artificial sweetener. In fact, I have grown a % of my supply myself, on my balcony.

Stevia is used in soft drinks and other foods/drinks extensively in Japan and S.America. Has been for decades. There has been a misinformation campaign against Stevia, promulgated by the artificial sweetener industry. Thank you for not adding to it.

Hi Tom,

Glad to know that Stevia has helped you. Thanks for sharing your feedback.

Thanks, Tom. I did not know that synthetic sweeteners create insulin resistance.

Kay Terry Bowers

Stevia is not synthetic. It is made from a leaf that is naturally sweet and does not affect blood sugar.

This my understanding. Being not sugar,but sweet dose not mean synthetic .

If sweetness is a concern try brewing Oolong tea for around 10 seconds, dump the first brew (this gets rid of the caffeine and opens the leaves), the next 4 or 5 cups brew for about 10 seconds this will keep the tannins(tartness) low and the flavors high.

Except that stevia is a plant, not an artificial sugar.
