Note: We use the term “Chinese Black Tea ”as it is commonly used in the West to describe what are actually known in China as Red Teas. The true Chinese Black Teas as they are known in China are the post-fermented, aged teas such as Pu-Erh Tea.
In the manufacturing of red tea (紅茶 Hóng Chá), the tea leaves are withered and crushed to cause enzyme-mediated oxidation in a process commonly referred to as “fermentation.” During this process, most of the catechins are oxidized, oligomerized, and polymerized to form theaflavins and thearubigins, which provide the red-brown color of black tea.
In brewed black tea catechins, theaflavins and thearubigins each account for 3-10%, 2-6%, and greater than 20% of the dry weight, respectively.
The caffeine contents in black tea is less then in green tea.
Health Benefits of Black Tea
Black tea is beneficial due to its unique making process: fermentation. Fermentation is the key process of making black tea. The chemical change of polyphenols produces the special aroma and color of black tea, as well as its health benefits.
Thearubigins – The Benefits of Fermentation
Fermentation is aiming to promote the oxidization of polyphenols, which will produce thearubigin and theaflavin. Thearubigin exists in black tea, is a kind of golden pigment produced in fermentation. Beside of adjusting the color of tea liquid, thearubigin has many health benefits.
It can combine with cholesterol in stomach and intestines, and reduce the amount of cholesterol absorbed from food. Thus thearubigin is helpful for protecting your heart from hyperlipidemia and heart disease without any side-effect.
This efficacy is because of thearubigin’s ability of weakening FAS (fatty acid synthetase). FAS is the primary enzyme of producing fat. That’s also the reason why thearubigin can help reducing the amount of triglyceride in blood.
Black tea contains higher amount of flavone than other kinds of teas. Flavone is able to protect heart and vessels. Being the power source of blood circulation, human’s heart will beat at the average rate of 70 times per minute. Presume a man is 70 years old; then in the past 70 years, his heart should have beaten for over 2.6 billion times. Too much fat in blood will bring big pressure to the heart.
The fat will stack on vessel wall. As a result, vessels will be blocked, causing cerebral infarction and poor blood flow. However, flavone can ease these uncomfortable feelings. So drinking black tea can protect your heart from cardiovascular disease.
More Benefits of Black Tea for Your Health
Protecting bones: polyphenols in black tea can restrain the active matters which harm bone cells. There are research findings that people who drink black teas regularly have stronger bones. To prevent osteoporosis, you can drink a cup of black tea every day, and keep as a habit for years. If you add lemon into black tea, you will have a better effect of protecting your bones. Black tea can be mixed with other fruit as well.
Protecting stomach and intestines: the enzymatic oxidization happens during fermentation will reduce the amount of polyphenols in black tea.
Thus black tea becomes gentler. Furthermore, as polyphenols may stimulate stomach, which acts stronger in an empty belly, black tea with lower polyphenol amount can help to protect your stomach. Black tea can be mixed with sugar and milk.
Regular drinking of it can diminish inflammation in your stomach, and protect stomach lining, even help to cure gastric ulcer.
Different Theory Of Protecting Stomach From Pu-Erh Tea
We have introduced about Pu-erh’s benefits of losing weight in the article Pu-erh Tea Weight Loss. We know that Pu-erh contains plenty of beneficial bacteria, which are produced in the process of Wo Dui.
These beneficial bacteria are good for stomach and can help weight loss. Bunches of beneficial bacteria living in intestines will be good to your health. They could restrain the absorbing of cholesterol, reduce the synthesis of it, and protect your blood.
However, black tea works in a total different way. During the fermentation process of making black tea, the polyphenols in tea leaves will be enzymatic oxidized, and then produce therubigin and theaflavin. The TR and TF are beneficial substances, which are very helpful for your health.
Take Warm Black Tea in Winter
The benefit of black tea for warming stomach is extraordinary. In cold winter days, it is better to drink warm teas with gentler taste. Take a cup of black tea. It will reduce the discomfort feelings in stomach.
On the other hand, green tea contains abundant polyphenols, which makes the liquid of green tea taste more brisk and refreshing. That’s why green tea is better for summer drinking.

We suggest you to drink black tea with proper amount. But why shouldn’t we drink as much as we can sinceblack tea helps to warm up the stomach?
Tea lovers often encounter the situation of sleeplessness after drinking too much tea, which was calledrepercussion. It is because tea contains caffeine, causing nervous excitation. Though caffeine is helpful for refreshing your minds, it is better not to drink too much.
Another reason is that too much tea liquid will dilute gastric juice in your stomach, while the gastric juice can protect your stomach wall. Moreover, tea polyphenols is astringent. It may cause discomfort of stomach. Over-intake of tea polyphenols may even cause tea drunk.
If you are drunk, allergy may happen, as well as sleeplessness, headache, trembling, or even heart rate disorder.
