It's something many Americans would never consider. I mean, seashells on your breasts? Why the hell would you do that?
Patella vulgata shells have been worn by Norwegian, Danish, and Swedish mothers for thousands of years.
The shells are an ancient remedy for nipple sores, ranging from splits and cracks, to bleeding and blisters. According to a Swedish online site that sells the shells, they create a soothing microclimate so that nipples soften and are moisturized by breastmilk—which contains lactoferrin—known for its antiviral and antibacterial healing properties.
Just...wow. I am truly amazed. You learn something new every day.
