We've already heard about Blue Tea , but it's no surprise that teas are named after colors lately, such as white tea, red tea, green tea, or black tea. In this post, we'll talk about blue tea: what it is, its properties, and its benefits.

What is blue tea?

Also known as blue oolong tea , it originates in Asia and is appreciated for its distinctive flavor, somewhere between green and black tea, although its aroma is more fruity and floral. However, it's not just its distinctive flavor that makes it stand out, but also its natural and rapid slimming effects, as certain studies have shown.

Blue oolong tea is a semi-fermented tea that contains little caffeine but a high amount of tannins. Its name is of Chinese origin and means "Black Dragon Tea," although we already mentioned that it's a tea somewhere between green and black. When you taste a cup of this tea, its flavor and aroma transport you to the highest mountains in Taiwan or certain parts of China.

It comes from the tea tree, Camellia sinensis , which is harvested primarily in the Chinese province of Fujian, where the Ti-Kuan-Yin variety is produced and retains many of the characteristics of green tea. Another variety known as Formosa Oolong is grown in Taiwan and has a stronger flavor than the one produced in Fujian.

Blue tea leaves have been processed to a state of oxidation that gives them a bluish-black color, also providing certain notable organoleptic characteristics. Oxidation is possible thanks to the aeration and exposure of the leaves. The time taken to ventilate and dry blue tea is shorter than that used for black tea . In this sense, its oxidation will be temporary and this is what determines its particular intense aroma.

What properties does blue tea have?

Below, you will learn everything related to the properties of blue oolong tea:

Antioxidant effects. Blue tea has a good amount of antioxidants that act against free radicals, helping prevent chronic diseases and premature aging. Its antioxidant effects are due to its flavonoid content, a substance that protects against tissue damage.
Reduces cellular aging. Its flavonoid content slows the action that causes cellular aging.
Controls blood sugar spikes. According to a study, drinking six cups of blue tea daily for 30 days helps control blood sugar levels.
It has been used for years as a natural slimming aid; in fact, it has been recommended in Chinese herbal medicine. Consuming blue tea helps speed up metabolism, which promotes weight loss thanks to its high polyphenol content.
It prevents cardiovascular disease. It helps maintain balanced blood pressure and lowers cholesterol levels. It also protects the heart and reduces the risk of heart attacks.
It works against cancer. Blue tea contains polyphenols, theaflavins, and thearubigins, which, thanks to their antioxidant properties, protect cells from free radicals.

What are the contraindications for taking blue tea?

Blue tea itself, if consumed in moderation, is very healthy, but it contains certain components that can be harmful. Below, we'll discuss the contraindications of blue oolong tea:

During pregnancy or breastfeeding. All teas made from Camellia sinensis contain some caffeine, although it is not very high, but it can be harmful during pregnancy or breastfeeding.
If you have high blood pressure, avoid drinking it or drink it in moderation.
If you suffer from anxiety. In these cases, it is contraindicated because it may worsen the disorder.
It is also not recommended for those who have clotting problems because it can worsen bleeding.
If you suffer from diarrhea, drinking a lot of blue tea can make your condition worse.
For those who suffer from irritable bowel syndrome. Drinking it while suffering from this syndrome can be very counterproductive; it could worsen symptoms and even diarrhea.
For those suffering from glaucoma, blue tea increases internal eye pressure.
If you suffer from osteoporosis, it's recommended to drink a maximum of three cups a day. Studies suggest that caffeine eliminates calcium through urine.
For those with anemia. Tannins are more present in blue tea than in green tea . Therefore, this could decrease iron absorption during meals, because it prevents proper assimilation.
If you have kidney problems. Blue tea, because it contains oxalate, promotes the formation of grit and kidney stones.
Since it contains fluoride (a substance considered carcinogenic), it can cause harm, although the quantities are minimal.
