Oxytocin is a natural human hormone primarily  known for its significance during pregnancy/birth.

However, many new aspects of its possible additional properties are known today.
New research (from animal studies) suggests that it may help to

– reduce alcohol craving and consumption
– reduce alcohol toxicity
– reduce alcohol withdrawal symptoms.

These new findings might helpt to develop a new koind of „sobriety pill“ eventually.
