How to make herbal tea?

I think it is advisable to drink herbal tea in summer.

Cold tea making, that is, making tea with cold water, can be said to be a way to subvert the tradition. Herbal tea is called "cloud water tea" in Japan. In Japan and Korea, many families soak wheat tea, oolong tea and green tea in cold water every morning, then put them in the refrigerator and drink them all day.

Generally, if you are not skilled in making tea, or the water temperature is too high or the brewing times increase, there is the possibility of theophylline release. There is no chance to drink too much theophylline when making tea with cold water. Someone has done experiments. When green tea is soaked in cold water for 4-8 hours, catechins beneficial to health can be effectively leached, while caffeine is only below 1/2. This soaking method can not only reduce the release of caffeine, but also does not hurt the stomach and affect sleep, which is suitable for people with sensitive constitution or weak stomach.

Ordinary green tea is the best, and the tea leaves are soaked for about 4 to 8 hours. As for the brewing ratio of tea and cold water, for example, about 350ML of mineral water is generally matched with 2-3 grams of tea.

Of course, West Lake Longjing can be made into herbal tea with cold water. In a slightly higher glass, add a little cold water at room temperature, add Longjing tea, let it soak naturally for 1~2 hours, and then add ice cubes. When the ice cubes melt into water, it becomes the best herbal tea.
