Do placing various oils in your belly button have any health benefits?

I used to think that the belly button didn’t really do anything for our bodies. I assumed that the mother’s blood was the only source of oxygen and nourishment for the embryo at this specific starting location. What further purposes may the belly button serve?

However, a startling assertion that appeared in a number of online publications about “oil in the belly button,” “belly button oiling,” and “navel treatment” led me to believe otherwise.
