Are starbuck teas safe during pregnancy.?

Possibly not: Some components of the teas that Starbucks makes can potentially be unsafe in pregnancy. As you are concerned then stay clear of them. See the link below for another opinion. http://www.bottlesoup.com/2014/06/16/a-starbucks-guide-for-pregnancy/

Hard to say: As it depends on the type of tea, herbal vs non-herbal, and within herbal, it depends on the "herbs" included. In general most commercial teas are felt to be safe as long as consumed in moderation. But you'd be best reviewing the types of tea that you are consuming or would like to.
