Is herbal tea days before a surgery cause for cancellation?

I am having a lump in my breast removed on Friday (2.5 days) in order to biopsy it. I was told to stop all herbal medications two weeks prior to the surgery but nothing was said about herbal tea. It didn't cross my mind and I've had several cups over the past few days. Am I going to have to cancel the surgery? I was told I am not going under general anesthesia if that makes a difference.
