Teas are consumed daily in many different cultures. Some drink it for its taste, some for relaxation and some for its health benefits. As long as you have it in moderation, this beverage can be enjoyed every day.
The longer the drink is brewed for, the longer the ingredients have to release their flavor. If you prefer a less bitter taste, dilute it with more water or cook it for a shorter period of time. Alternatively, use more sweetener.
