Question:

Is it Ok to drink green tea during pregnancy?

Response: 

Green tea is a beverage that has been consumed in China for more than 2000 years. From a culture point of view, green tea is the Chinese people's daily fluid intake, male or female, pregnant or not. From medical point of few, drug free pregnancy is the principle. Since green tea does contain 1/4 of a cup of coffee's caffeine, we therefor recommend to drink in moderate amount - not more than 2 cups a day.
