The year 2025 has arrived in the blink of an eye, and health is undoubtedly the most concerning topic for everyone in recent years.

The arrival of diseases and accidents is inevitable. We can only prepare in advance and do a good job in prevention to continue our beautiful lives.

Nourishing by drinking tea is the top priority in the cold winter

At the groundbreaking ceremony of the Hengqin Hospital affiliated with the First Hospital of Guangzhou Medical University (Hengqin New District Central Hospital) and the Hengqin Zhihe International Life Science Center, Academician Zhong Nanshan, recipient of the “Medal of the Republic,” delivered an important speech.

Academician Zhong Nanshan stated:

“The tea made from this (dried tangerine peel) was indeed favored by many people in the north and northeast during a period of severe air pollution. I wondered why? Later, we conducted some animal experiments. One group of animals drank this (dried tangerine peel) tea, while the other served as a blank control. We used strong car exhaust to create lung pollution in the animals through experimentation.

The results showed that using tea and dried tangerine peel significantly improved the elimination of mucus and pollutants. This is why the common people like it. This is a piece of research we have done, and we plan to conduct another study and publish it. This is what we did, which is about health.”

Chinese people pay attention to following the laws of nature when drinking tea for nourishment. Tea is taken from between heaven and earth and processed naturally, adhering to the principles of health preservation.

A tea lover gradually builds up a healthy body through drinking tea, which is the best reward tea can give to those who love it.

It is particularly suitable for those with low immunity, obesity, excessive smoking and alcohol consumption, late-night smartphone use, and office workers who sit for long hours to nourish themselves by drinking tea.

If you have such people around you, consider sharing this healthy lifestyle of drinking tea with them. A cup of tea conveys care and brings warmth in return.

What health-promoting substances are there in tea?

Tea Polyphenols

Tea polyphenols refer collectively to flavonoids, phenolic acids, catechins, and anthocyanins in tea.

Their main effects on the human body include: lowering blood Sugar and lipids; promoting blood circulation and resolving stasis, inhibiting arteriosclerosis; antioxidation and delaying aging; antibacterial, anti-inflammatory, and antiviral; and eliminating bad breath.

In addition, because tea polyphenols can protect the brain and prevent damage to the skin from radiation, tea beverages rich in tea polyphenols are known as “beverages for the electronic age.”

Amino Acids

The amino acid content in tea usually accounts for 1%-4% of the dry weight of the tea. The amino acids in tea dissolve easily in water and impart a fresh and sweet taste, similar to monosodium glutamate.

Among them, theanine is a unique amino acid found in tea plants and is rarely seen in other plants. It is also a characteristic substance in tea plants.

Alkaloids

This is a class of purine derivatives containing a purine ring. The main alkaloid in tea is caffeine.

The caffeine content in tea ranges from 2% to 5%. About 80% or more of the caffeine dissolves in boiling water after steeping tea.

Caffeine has stimulating and diuretic effects on humans. Therefore, tea is a good stimulant and diuretic.

Vitamins

Vitamins are one of the six essential nutrients required for normal metabolism in the human body and are abundant in tea.

In particular, B vitamins, vitamin C, vitamin E, and vitamin K are present in significant amounts.

B vitamins can stimulate appetite; vitamin C can kill bacteria and detoxify, enhancing the body's resistance; vitamin E has antioxidant properties and certain anti-aging effects; vitamin K can increase intestinal peristalsis and secretory function.

Fluorides

Generally, foods contain very little fluoride. Tea contains relatively abundant fluoride, usually ranging from 0.002% to 0.025%. Approximately 40-80% of the fluoride in tea dissolves in boiling water.

Effects: strengthens teeth, making the enamel harder and preventing cavities and tooth decay.

Sugars in Tea

The sugars in fresh tea leaves include monosaccharides, oligosaccharides, polysaccharides, and small quantities of other sugars. Monosaccharides and disaccharides are the primary components of soluble sugars in tea.

The polysaccharides in tea mainly consist of cellulose, hemicellulose, starch, and Pectin.

About dried tangerine peel, Li Shizhen's “Compendium of Materia medica” from the Ming dynasty provides detailed descriptions: “Tangerine peels have coarse patterns, are yellow and thick, with much white membrane inside, and have a spicy-sweet taste… today, those collected from Guangdong (Xinhui) are considered superior.”

The focus of “dried tangerine peel” lies in “aging,” and it must be stored locally and aged at its place of origin, with three years being the minimum to be called dried tangerine peel.

We are no strangers to dried tangerine peel. As the saying goes, “An ounce of dried tangerine peel is worth an ounce of gold, and a century-old dried tangerine peel is better than gold.” Although dried tangerine peel is not as precious as gold, its medicinal value is indeed astonishing.

According to Traditional Chinese medicine, dried tangerine peel has a spicy and bitter taste and is warm in nature. It targets the spleen and lung meridians.

It has the functions of strengthening the spleen and harmonizing the stomach, regulating qi and widening the middle, and descending qi and transforming phlegm. It is primarily used to regulate qi and strengthen the spleen, dry dampness and transform phlegm. It treats chest and abdominal distension, reduced appetite, vomiting and diarrhea, excessive coughing and phlegm, stagnation of spleen and stomach qi, nausea and vomiting, poor appetite, and fullness of the chest and diaphragm.
