Best tea?

I’m looking for a good breastmilk tea. Do they even really work? My daughter is 3 weeks old and is mainly formula fed due to complication in the hospital. I want to try to get her back to the boob which I’m working on very slowly but it’s hard and it’s going to take time. Also due to not pumping as much as I should I don’t produce that much. I’m trying to get better about pumping and trying to get her to take my boob. She had pretty bad nipple confusion and gets extremely angry. I just need a pep talk lol. Anyways what’s the best tea to help and do they really work? I know working on the other things will help a ton but if I can even drink tea to help a little I will. I find it so beautiful that my body can do something so amazing.
