where to check ingredients safety

[StrongFeather]

Is there a good website to check whether an ingredient is safe to take/ingest while breastfeeding? I recently had a sore throat and a friend bought me some teas (throat coat and triple echinechia) and both of them state: "do not use if pregnant or nursing." I can't figure out for the life of me what ingredients would be harmful.

Any one know where I can check them?

Check out Dr. Hales site- he's like the go to guy

also- all tea will say that as a disclaimer. It's never been tested

Even drugs that have been tested and approve can say that - my L1 thyroid medication says that. It's a CYA kind of thing.
