Although a fully ripe papaya is not considered dangerous, a papaya that is at all unripe contains a latex substance that triggers uterine contractions and may cause a miscarriage.
The papaya enzyme that helps soothe indigestion is called papain, or vegetable pepsin. Papain is found in the fruit's latex and leaves.
1 Researchers have noted that unripe papaya latex acts like prostaglandin and oxytocin, which the body makes to start labor.
2 Synthetic prostaglandin and oxytocin are commonly used to start or strengthen labor contractions.
