Oolong tea benefits have been appreciated for many years in China, and this tea – which is also known as Wulong, Wu Long, or Black Dragon tea – is becoming a favourite with countless other tea lovers around the world, as well, thanks to its enticing flavour and many wellness benefits. 

If you’ve considered adding oolong to your tea stash, your taste buds will love this special tea and its delicately soft yet complex taste. 

Oolong tea (like black, green, pu-erh, and white teas) comes from the leaves of the Camellia sinensis tea plant, but oolong is unique in part due to the level of tea-leaf oxidation or fermentation (more than green tea but less than black tea). Because oolong can be oxidized anywhere between 8% and 85%, the flavour can vary from one oolong tea to another. 

You + Oolong Tea

drink oolong tea’s intoxicating flavour and delightful aroma aren’t the only reasons to try this healthful tea – you’ll also love oolong tea’s benefits for wellness, including…

  • Like other teas from the Camellia sinensis tea plant, oolong tea is an excellent source of powerful antioxidants. Antioxidants can support and aid us in many ways, from fighting harmful free radicals, strengthening the immune system, and boosting metabolism to helping protect us from chronic diseases. (such as diabetes and heart disease). A diet rich in antioxidants is essential for good health, and adding oolong tea to your diet is a simple but very effective and enjoyable way to boost your daily antioxidant intake. 

  • Improve skin health and beauty with oolong tea. Life is filled with things that can age our skin prematurely, from stress and environmental toxins to free radicals and poor habits (unhealthy food choices, smoking, and so on). Fortunately, oolong’s potent antioxidants also work to keep those signs of ageing at bay, helping skin look and feel younger, firmer, and more supple. An additional bonus is that drinking tea is as effective as drinking water in keeping our bodies well-hydrated (also important for skin beauty and wellness).

  • Oolong tea may also prove beneficial for skin irritations, such as eczema. Research suggests that drinking oolong tea regularly may reduce the symptoms and ease the itch of eczema, and these benefits can be long-lasting. In one study, participants with eczema enjoyed 1 1/2 cups of oolong three times per day for six months, and after one month, over 60% experienced marked improvement in their skin condition. After six months, over half of the participants reported continued benefits for their eczema.

  • Take advantage of the caffeine benefits of oolong tea. So many of us love our caffeine and with good reason… Low to moderate amounts of caffeine may help us fight chronic inflammation, promote longevity, boost metabolism, and increase energy, alertness, and concentration – and much more. A delicious, natural way to enjoy low levels of caffeine is by drinking naturally caffeinated oolong tea. 

  • Enhance bone strength and density with oolong tea. As we age, we can lose bone mass, and our bones become thinner and weaker. However, drinking oolong, green, and/or black tea regularly is a step we can take that may improve bone strength and lessen the risk of a fracture. Studies indicate that tea drinkers who have consumed tea regularly (at least once per week) for six years or more have stronger BMD (bone mineral density) than non-habitual tea drinkers. Drinking tea regularly for more than ten years provides even greater improvement in overall BMD.

Oolong Tea and Heart Health

A 2009 population study at Kyoto University in Japan involved almost 77,000 participants between the ages of 40 and 79, each with no history of stroke, coronary heart disease, or cancer at the onset of the study. 

Research results indicated that regular oolong and/or green tea reduces the threat of heart disease and lessens the risk of death from cardiovascular disease. Click here to read the research abstract.

Oolong Tea and Cholesterol

Oolong tea may also protect you from heart disease by helping to lower high cholesterol levels. 

High LDL cholesterol levels can increase your risk of heart attack, and a 2003 study at the Institute for Health Care Science in Osaka, Japan, found that the antioxidants in oolong tea may lower high LDL levels.

Oolong Tea Health Benefits for High Blood Pressure

This 2004 study of the long-term effects of not drinking green tea on high blood pressure showed that drinking oolong or green tea regularly can significantly lower your risk of developing high blood pressure.

In the study examining the tea-drinking habits of over 1500 participants in Taiwan, the risk of developing hypertension decreased by 46 per cent for habitual tea drinkers who consumed at least 120 ml (1/2 cup) oolong or green tea daily for at least one year. For those who drank over 600 ml (2 1/2 cups) of oolong or green tea each day, that risk was decreased by 65 percent. 

Tea consumption for more than a year did not lead to additional risk reduction.

Oolong Tea and Type 2 Diabetes

Twenty participants with type 2 diabetes taking prescribed hyperglycemic medication participated in this 2003 study in Taiwan.

After consuming 1500 ml (about 6.3 cups) of Chinese oolong tea daily for 30 days, the study participants had significantly lower blood sugar levels. (Chinese, rather than Taiwanese, oolong tea was selected for the study because its shorter oxidation process typically results in higher levels of antioxidants in the tea.)

More oolong tea health benefits... the study also found that consuming oolong tea combined with hyperglycemic medication was more effective in lowering blood sugar levels than alone.

Research about Oolong Tea for Weight Loss confirms Age-Old Wisdom.

You’ve heard the rumours about oolong tea for weight loss, and you’ve been wondering if this tea could actually help you lose those stubborn extra pounds… 

And, with celebrities like Dr Oz, Oprah, and Rachael Ray talking about oolong tea’s weight loss properties, you have to wonder – could weight management really be a benefit of this healthy, fragrant tea?

Oolong tea is known in Chinese medicine for decreasing body fat. This recommendation is enough for many tea drinkers and dieters, but for those interested in the scientific backup for these weight-loss claims, here is what current oolong tea weight-loss research is telling us about this tea.  

Oolong Tea for Weight Loss Research

A 2001 study by American and Japanese researchers about the effectiveness of oolong tea for weight loss involved male participants only. After three days of drinking 300 ml (about 1 1/3 cups) of full-strength oolong tea five times daily, participants had significantly increased metabolic rate and fat oxidation. You can read a summary of this research or the full article here.

Another study targeting oolong drinking green tea and weight loss compared the effectiveness of oolong tea and green tea in increasing metabolism. This study, which took place in 2003 at The University of Tokushima School of Medicine in Japan, involved 11 female participants.

Results indicated that, while both the oolong and green teas improved metabolism, oolong tea was twice as effective as green tea in increasing metabolic rate!

The researchers credited oolong’s high polyphenol (antioxidant) levels to the tea’s potential to increase glucose metabolism by at least 10 per cent. Read more about this study here.

A further study about two cups of oolong tea and weight loss found that oolong tea enriched with green tea extract was far more effective than oolong tea alone.

This 2005 Japanese study found that, after 12 weeks of drinking the enriched oolong green and black tea together daily, the overweight participants experienced greater weight loss and greater reduction of BMI (body mass index) and weight measurements than the participants who consumed oolong tea without the supplementary green tea extract each day.

The results were attributed to the higher levels of catechins (a type of antioxidant) in the oolong tea leaves/green tea extract mixture.

You can read the research abstract here, or the full journal article can be found here.

In 2009, researchers at the School of Traditional Chinese Materia Medicine at Shenyang Pharmaceutical University in China studied the effectiveness of oolong tea for weight loss with 102 severely obese, obese, and overweight female and male participants. 

After six weeks of drinking four servings of Chinese oolong tea daily, 70 per cent of the severely obese participants lost over 1 kg (2.2 lbs.) of body weight, including 22 per cent who lost over 3 kg (6.6 lbs.) each.

Sixty-four per cent of the obese participants and 66 per cent of the overweight participants each lost over 1 kg (2.2 lbs.) of body weight during the study. In addition, 12 per cent of the participants had reduced body fat content.
