This line of discussion has me a bit concerned. Both methods (IMHO) are more of a hindrance than a help in healing sore nipples. Hydrogen peroxide has been shown to destroy newly developing cells, hence is no longer recommended in the care of surgical sites. Tea has acid in it, need I say more? I am currently working with a mother who was advised to use tea bags on her slightly sore nipples. They have been "burned" to the degree that we are using hydrogel dressings to try and heal them. She is presently unable to breastfeed her baby because she was given no guidelines or limitations on how often or long to use the tea bags. In the past tea bags were used to "soothe" sore nipples, but should only be used once or twice in a day and certainly not for more than a day or 2. I personally will not use them any more. Mary A.
