Myths about black tea

Tea consumption in 2014 was 27.5 litres per capita. This corresponded to a quantity of 19 176 tons of tea. The share of black tea was 71 per cent, and the share of green tea was 29 per cent. In 2014, the world production of tea of five million tons was exceeded for the first time. The Germans chose 60 percent loose teas, while only 40 percent opted for convenience solutions, i.e. tea bags or tea capsules. Black tea is produced from green tea by oxidation (formerly called fermentation). During oxidation, green tea is treated with 30 degrees Celsius warm, humid air. This unfolds the oils and the typical aroma of black tea.

Note: Scientifically speaking, there are only six types of tea. These are: Black, Green, Yellow, White, Oolong and Pu Erh. Whereas chamomile, peppermint, rose hip and other teas scientifically belong to the "Sud". But these brews are popularly called tea. It has just become so popular and the industry has accepted it and prints it on the packaging. Examples can then be found in the supermarket: "black tea", "camomile tea", "rose hip tea", etc.

Black tea can have a calming effect

Wrong! In the vernacular the myth still goes round, "let the tea steep for at least five minutes, then it has a calming effect". Black tea contains caffeine (formerly Teein. Caffeine and Teein are chemically completely identical, that's why we don't speak of Teein anymore). The longer a tea steeps and the hotter the water, the more ingredients are released from the tea leaves. Black tea contains about three to three and a half percent caffeine. Nature simply dictates this amount. Even a longer infusion time does not reduce the caffeine content of the tea. Black tea contains tannins and other tanning agents and caffeine. Caffeine is released from the tea leaves very quickly. The time is between one and three minutes. The tannins and tannins take a little longer. The time is between two and four minutes. The longer the tea draws, the more tannins are released from the leaves. After that the tea may taste more unpleasant. A longer infusion time does not break down the caffeine. Nobody knows why this myth persists so stubbornly in the third millennium. The old, false knowledge is passed on from generation to generation. And then there are examples of relatives that nobody can verify. But there is science that tests these myths. But the results are clear and can be repeated again and again.

Black tea makes dark eye rims fade

Right! Black tea with its ingredients can help reduce the swelling of swollen eyes and eye bags. The tea can also make dark eye rims disappear. This is achieved by the tanning agents contained in the tea, the so-called tannins. These have an antibacterial and soothing effect on the skin. For this purpose, the tea should be natural, i.e. without additional aromas. Tea bags can be used. The tea can also be taken loose. It is important to soak the tea bag/tea in cold water for one hour. Afterwards the bag cools down additionally on the skin. If you use loose tea, you should put the tea leaves in a small linen cloth and then place it on the skin. The dwell time on the skin should be at least 20 minutes. Those who do this procedure with green tea will achieve faster results. This is because green tea is not fermented compared to black tea.

Black tea is good for the teeth

Right! In addition to vitamin from the B group, tea contains potassium, manganese and fluoride. Our teeth need fluorine to stay healthy. Anyone who drinks black tea every day can stain their teeth brownish if they do not take sufficient care of their teeth. This is certainly not in the sense of an ideal of beauty.

Black tea is good for the gums

Right! But only if it is drunk without sugar. Because it has a slight antibacterial effect.

Black tea lowers the cholesterol level

Right! This is what the Chinese want to find out in a large-scale study. However, scientists in the Far East speak of higher doses.

Black tea is just as stimulating as coffee

Wrong! A cup of coffee has much, much more caffeine than a cup of black tea. Because for one cup of coffee you need 5 grams of powder and for one cup of tea only one or two grams of tea. So coffee contains two to three times more caffeine than tea. In addition, the caffeine in tea is absorbed more slowly by the body. If the tea is steeped for a longer period of time, more tannins are released from the leaves, which form a chemical compound with the caffeine, which is then absorbed even more slowly by the body. Conclusion: the body also absorbs the low-dose caffeine in tea hesitantly and more slowly. It is comparable to drinking a cup of coffee with only half the amount of coffee powder. Well, then it will probably not taste good anymore.

Black tea is diuretic

Right! In general, all tea is diuretic. It depends on the amount. A cup is not diuretic for most people. Five cups and more are. If you only take tea and rusk because of a stomach upset, you should take countermeasures to prevent your body from losing too much water and becoming slightly dehydrated. In addition to tea, still water can also be drunk in appropriate quantities.
