6. Safety information of Oxytocin
Poison by intravenous route. Experimental reproductive effects. A pituitary hormone which stimulates uterine contraction and milk production. The principal uterus-contracting and lactation-stimulating hormone of the posterior pituitary gland. Note: Unlike vasopressin which occurs in at least two forms, Oxytocin from beef and hog sources shows no difference in amino acid composition. When heated to decomposition it emits toxic fumes of SOx and NOx.

7. Uses of Oxytocin
Oxytocin (CAS NO.50-56-6) is the principal uterus-contracting and lactation-stimulating hormone of the posterior pituitary gland.It is released in large amounts after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding, respectively. It is a mammalian hormone that also acts as a neurotransmitter in the brain.
