The harm of tea stain

Tea is an indispensable part of our lives. Many people choose to make tea in their spare time to take a break and relax. But those who have made tea know that there will be a layer of tea scale on the teapot or other utensils after brewing tea. Over time, the tea scale will increase. Many people do not take it seriously, but in fact, tea scale will have many bad effects on our body. The following is an explanation of the hazards of tea scale. Let us learn about it now.

Tea scale is caused by the oxidation reaction between tea polyphenols in tea leaves and metal substances in tea rust in the air. Various metals such as cadmium, lead, iron, arsenic, mercury and other substances harmful to the body, such as nitrite, will adhere to the smooth surface of the teacup. During the process of planting and roasting tea, heavy metals in the soil and utensils may enter the tea. If the tea leaves are contaminated or the drinking water contains heavy metal ions, the tea scale formed is likely to contain more heavy metals.

Yang Jing, a doctor from the clinical nutrition department of the Municipal People's Hospital, said that elements such as arsenic, mercury, and lead in tea stains can have a great impact on the body's nervous system, and can cause blood system diseases, digestive system lesions, and functional disorders.

According to the experts’ explanation, it turns out that tea stains can cause harm to the human body which cannot be underestimated. Therefore, every time after drinking tea, even if there is no tea stain on the cup, you must clean it carefully. So what are the requirements for cleaning tea stains?

Tea stains are easily dealt with:

The best cleaning method is: tea drinkers should wash the cups frequently. After each cup of tea, remember to pour out the tea leaves and clean the tea set with water. If you can maintain this good habit for a long time, you don't need any cleaning tools and the tea set will keep its bright luster.

For tea cups that have been covered with tea stains for a long time, you can remove them by scrubbing them repeatedly with toothpaste.

For teapots with tea stains, heat rice vinegar or soak them in baking soda for a day and night, then shake and rinse repeatedly to clean them.

Many tea lovers not only pay attention to the tea leaves and water sources when drinking tea, but also have certain requirements for tea sets, and the purple clay teapot is one of the finest ones. Tea brewed in a purple clay teapot is more fragrant, but there are also special skills to cleaning the teapot inside and out.

Ye Zhijian, vice president of the Heyuan Tea Circulation Association, said that purple clay teapots generally do not need to be cleaned, and when cleaning the outside, chemical substances such as baking soda and bleaching powder must not be used, as they will cause great damage to the purple clay teapot. You can add some warm water, pour the water on the outside of the teapot first, and then wipe it slowly with cotton cloth.

The purple clay teapot itself has pores, and the minerals in the tea scale can be absorbed by these pores, which can maintain the teapot and will not cause harmful substances to "run" into the tea and be absorbed by the human body.

"When drinking tea, you should wash the cup frequently, and there are certain rules for cleaning tea stains." Citizens who like to drink tea in daily life should be more careful. The so-called "drinking tea for health" should also be based on washing the cups frequently. Only by learning to drink tea in a healthy way can you drink tea for a healthy body.
