Himalayan Oolong Tea: Nutrition and Health Benefits June 10, 2022 07:05

Himalayan Oolong tea is a traditional orthodox tea , and it is sparsely produced in the eastern Himalayas of Nepal. It comes from the same Camellia Sinensis plant which is used to make black,white and green tea. The leaves go through a special  oxidation process that impacts its color, flavor, and nutritional content. Oolong teas are darker in color with a fruity and earthy taste.

Nutritions in Oolong Tea 

Oolong tea contains a variety of vitamins, minerals, and antioxidants. A cup of oolong tea contains a good amount of calcium, magnesium, and potassium, so it's a healthy practice to start your day with a cup of oolong tea.


The L-theanine amino acid in Oolong tea is responsible for providing you with positive effects on relaxation and cognitive performance. Moreover, Himalayan Oolong tea also contains some antioxidants such as polyphenols, theaflavins, thearubigins, and EGCG, which have many health benefits.

How Oolong Tea is Made?

In order to understand Oolong Tea, it is very important to understand the importance of a process called oxidation, which is fundamental to creating Black and Oolong teas.


Oxidation is a process where the enzymes locked inside the tea leaves come out and get in contact with the oxygen in the open air and start turning darker as time goes by.


For easy understanding, we can compare this process with the browning of an apple. Once you cut it open and let it react with the Oxygen in the air, it starts turning brownish. 


Similarly, tea leaves are plucked and hand-rolled or machine-rolled to hurt it enough so that the inner enzymes appear on the surface to  react with the oxygen in the air, resulting in its oxidation. The longer it reacts with air, the darker it gets.


The making of Himalayan Oolong tea is an intricate  process. It takes a lot of steps until the Oolong Tea is ready to brew. Below is the step-by-step process of how Oolong tea is made in detail.

  1. Harvesting

    The making of Himalayan Oolong tea starts with harvesting. Lower mid-large leaves are considered to be best for oolong teas and are harvested mainly in the spring for higher quality steeps.

  2. Solar Withering

    As the leaves lose their moisture and start, they are spread outdoors for “solar withering”. The tea maker pays careful attention to the atmospheric conditions to control the moisture of the leaves. The leaves are tossed to ensure they are evenly exposed and have uniform dehydration. When the initial solar withering is done, the tea leaves are moved indoors to continue withering in larger steel-framed trays that provide uniform circulation of air.

  3. Oxidation

    After a third of the moisture is depleted, the leaves go for an oxidation process that causes a chemical reaction to add the flavor profile of the tea. In the oxidation process, the leaves are hand-rolled or machine-rolled to break down their cell walls so that it produces enzymes to react with the oxygen. The longer leaves are left for oxidation, the darker it gets.

    In the Oolong tea manufacturing process, the leaves are usually oxidized until their oxidation level reaches the range of 50-70%. However, in the spectrum of Oxidation, the tea is still called oolong tea if its oxidation level is between 20-80%. It’s completely up to the manufacturer to play with this gap to create the oolong tea that tastes the best.

    White and Green teas are not oxidized while black teas are fully oxidized teas, with the oxidation level from 80-100%.

  4. Kill Green

    Following the oxidation process, the leaves go through a “Kill Green” process where they are heated at high temperature to deactivate the enzymes responsible for the oxidation process and stop the chemical transformation of the leaves.

  5. Roasting

    After the kill green process, the Oolong tea leaves are roasted repeatedly which "toasts" the leaf transforming it into a fruitful flavor. Now the Himalayan Oolong tea is ready for packaging.

Triglycerides are a type of fat in your blood that is responsible for heart diseases and they contribute to the thickening of artery walls, ultimately increasing the risk of heart attack, and other heart diseases.

Multiple research has been done on oolong tea and it has been found oolong tea lowers the cholesterol level at high levels, reducing the chance of heart disease. A 2003 study showed that those who drank more than six cups of oolong tea per day had a lower rate of coronary heart disease as compared to the non-tea drinkers. Therefore, regular consumption of antioxidants tea like oolong tea may improve heart health. 

    • Improves Tooth and Bone Health

Using Himalayan oolong tea on a daily basis is good for your spooky skelly. According to a survey, those who drink 1 to 5 cups of oolong tea daily have a very high bone density than non-tea drinkers. The antioxidants and polyphenols consisted in oolong tea are what keep teeth and bones strong. The higher the bone density is, the lower the risk of fractures.

Moreover, research has shown that oolong tea consumption is best for dental health. It might help  prevent plaque and gingivitis, making your teeth overall healthier.

    • Fights Cancer Cells

Himalayan Oolong tea is full of catechins and antioxidants and these two compounds might  play a major role in preventing certain cancers such as lung, liver, esophageal, pancreatic, colorectal, and especially breast cancers. But it’s not like “drink tea, don’t get cancer” but to some extent, it stops cell mutations that lead to cancer.

Oolong tea is one of  the best tea from Nepal that contains a great combination of L-theanine and caffeine that help the drinker stay focused and avoid distractions. Consuming oolong tea regularly might also help in preventing neurodegenerative diseases such as Parkinson’s disease which is a nervous system disorder that affects movement.

Drinking tea regularly may help in protecting against neurodegenerative diseases such as Parkinson’s disease. Drinking 3 cups of oolong tea daily might increase the ability to fight free radicals and help maintain brain function and memory.
