Why is Oxytocin called the love drug?

Once the baby is born, oxytocin helps to move milk from the ducts in the breast to the nipple, and foster a bond between mom and baby. Our bodies also produce oxytocin when we’re excited by our sexual partner, and when we fall in love. That’s why it has earned the nicknames, “love hormone” and “cuddle hormone.” July 20, 2021: https://www.health.harvard.edu/mind-and-mood/oxytocin-the-love-hormone
