According to a recent article in the Journal of Evidence-Based Complementary and Alternative Medicine, prophylactic application of emu oil improves areolar skin barrier function that can help prevent sore nipples. Appropriate areolar hydration serves as one of a number of protective strategies for the nipple and areola during breastfeeding. Emu oil is anti-inflammatory, enhances skin permeation, is moisturizing, and contains antioxidant properties. A study of 70 mothers investigated the dermal properties of an emu oil-based cream on areola skin hydration for 2 days post delivery. Emu oil was applied to the areola following each breastfeeding. Results showed a marked improvement in areolar hydration which contributes to improved skin integrity. Optimal skin integrity (along with proper positioning, latch, and sucking) seemed a helpful approach in preventing cracked nipples.
Have you ever seen an emu with dry nipples?
