Due to its beneficial properties this tea is becoming as popular as black tea. It has become so popular that it is now being added to many beverages, dietary supplements and even in cosmetic products. Generally one teaspoon of tea is added to one cup of water.

Hottest steeping temperature (water temperature) is around 80 to 85 degree Centigrade which is equivalent to 175 to 190 degree Fahrenheit. Lower quality tea is steeped hotter and longer. Higher quality teas are steeped cooler and shorter but more tea leaves may be used.
