The difference between black tea and green tea

Posted on Sep 15, 2022      59

Green and black tea are the two main varieties of tea that the average person knows. The difference between these varieties is not clear: whether they are different tea bushes, or whether the leaves undergo different processing.

Let’s try to understand the major differences between the two teas, including their benefits for the body.

Black and green tea: what is the difference?

Green and black teas are leaves harvested from the same bush. That green and black tea are harvested from two different bushes is a myth. The raw material in both cases is collected from a plant called Camellia Sinensis.

So it’s definitely not about the type of shrub. In fact, the leaves have different colors because of the different processing of the raw material. Green teas basically only go through the drying process, but black teas go through a long fermentation process.

Most of the time, this process involves evaporating moisture from the leaves, then oxidation takes place, during which fermentation takes place. This is transforming the structure of the tea leaf.

Fermentation is triggered at elevated temperatures. After the tea leaf reaches the desired fermentation, it is dried in an “oven”. Green tea goes through squeezing out excess moisture.

The difference between black and green tea: its health properties

Black tea changes the structure of chemical compounds, green tea keeps it almost in a pristine state. The question logically arises: which tea is healthier, black or green?

Green tea keeps its original composition of the leaf (fermentation rarely exceeds 10%), so the leaves keep more antioxidants. They are rich in B vitamins (B, B1, B2, B15), vitamin A, C, P, fluoride, potassium, zinc.

Green tea:

  • Cleanses the body of toxins;
  • Slows the aging process because of the high content of antioxidants;
  • Effective in diseases of the thyroid gland because of the iodine content;
  • Supports healthy teeth and gums because it contains calcium and fluoride;
  • Lowers blood pressure;
  • Helps with weight loss.

Black tea is inferior to green tea in the number of nutrients, however, it is also rich in vitamins B, P and PP.

Black tea:

  • Increases the tone of blood vessels and capillaries;
  • Helps with nausea and stomach cramps because of the content of tannins;
  • Increases blood pressure;
  • Strengthens the immune system, helps the body resist infectious diseases;
  • Stimulates mental activity.

The question “Which tea is healthier: green or black” makes no sense, because each of them is useful in its own way.

The geography of teas

Green teas are mainly from Asian countries, China and Japan. One of the most popular varieties is oolong. But black varieties are predominantly made in the  India and Sri Lanka.

Can I mix green and black tea?

A question that arises often among tea drinkers. No one forbids mixing the two. However, it is worth considering the rules for brewing: when brewed with boiling water, green tea loses its properties - it needs a temperature of 70-80 degrees. Black tea, on the contrary, needs to be poured with water 95-100 degrees.

If you brew black tea with green tea, then the green tea loses the lion’s share of its beneficial properties. If you brew both kinds of tea with water of 70-80 degrees, then the black tea will brew badly and will not give the drink the substances and flavors.

It is better to brew black tea with herbs and herbal mixtures, as their brewing requirements are approximately similar.


Whatever healing drink was not tea, there were always contraindications to its use.

  • Pregnancy. Both black and green tea contain an impressive amount of caffeine, which negatively affects the development of the unborn child. In addition, tea speeds up the heartbeat, loads the heart and almost. These factors can lead to toxicosis. Therefore, pregnant women should limit the amount of tea in their diet.
  • Gastrointestinal diseases. Tea consumption should be limited for people who suffer from gastric and duodenal ulcers. Tea can increase acidity in the stomach, which will lead to complications of the disease.
  • Hypertension. Caffeine and theophylline in tea increase blood pressure, which can lead to headaches.
  • Insomnia. Here everything is simple: caffeine has a stimulating effect, it is contained both in black and in green tea. Those who suffer from insomnia should better bet on herbal drinks without the content of tea.
  • At high body temperature. Theophylline, which is contained in tea, contributes to an even higher fever. In addition, it has a diuretic effect, which negates the effect of antipyretic drugs. In such a case, it is better to pay attention to herbal remedies.
