Oxytocin
Oxytocin is a neuropeptide produced in the hypothalamus and released by the pituitary gland. Often called the "bonding hormone," it plays a key role in social behavior, trust, anxiety reduction, and stress response. Research also highlights its role in gut motility, wound healing, and anti-inflammatory effects.
