Do I have to throw away the tea bags for the first time?

The tea bag should be thrown away when brewing for the first time.

Tea bags are very common in daily life, because most of the tea bags sold on the market are triangular in shape, and the tea leaves inside are composed of small broken tea leaves, which can quickly brew the taste of tea, so they are very popular among everyone. However, when drinking tea, it is recommended to "wash the tea" for the first cup of tea, brew about half a cup with boiling water for about 1 minute, then pour out the tea to wash away some pesticide residues, dust, and impurities in the tea , bacteria, etc.
