What is the purpose of applying expressed breast milk to fissured nipples during mastitis treatment?

Applying expressed breast milk to fissured nipples serves the purpose of promoting healing. Breast milk contains numerous beneficial components, including antibodies, growth factors, and anti-inflammatory properties, which can contribute to the healing process of tissue. These components help in reducing inflammation and promoting cellular repair, which can facilitate quicker recovery of the damaged skin around the nipple.

While other options like reducing pain or preventing infection may be experienced benefits, the primary and most supported function of breast milk in this context is its role in promoting healing. This is due to the unique composition of breast milk that aids in tissue repair, making it a natural remedy for minor injuries such as fissured nipples associated with conditions like mastitis.
