Dear friends,
If you are pregnant or trying to become pregnant, avoid eating papaya or using a papaya product. Papaya is sometimes recommended for soothing indigestion which is a common ailment during pregnancy. 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. unripe papaya latex acts like prostaglandin and oxytocin, which the body makes to start labor. Synthetic prostaglandin and oxytocin are commonly used to start or strengthen labor contractions.
IF you are sure enough the papaya is fully ripened there is no harm in it but is unripened then its better to avoid during pregnancy.
