Can You Drink Wu-yi Slimming Tea, If You Are Still Breastfeeding?
Everything that I have read about Wu-Yi is that it is really just Oolong tea. Which is caffeinated so you really shouldn't have more than a cup a day of it if you are breastfeeding. It's really recommended that you not have any caffeine when nursing but I had to have a cup of coffee each morning and it was okay. But Wu-Yi isn't going to help you lose weight any faster than just regular caffeinated tea.
