Parsley Side Effects and Warnings

Written by FoundHealth.

Safety Issues

As a widely eaten food, parsley is generally regarded as safe. However, excessive quantities of parsley should be avoided during pregnancy, based on the evidence mentioned earlier that myristicin and apiol can stimulate the uterus. 1 Myristicin may also cross the placenta and increase the heart rate of the fetus. 2 Parsley is known as a plant that can cause photosensitivity , which is an increased tendency to sunburn ; this result, however, occurs from prolonged physical contact with the leaves, not from oral consumption of parsley. 3 4 5 Maximum safe intake of parsley in young children, pregnant or nursing women, or people with severe liver or kidney disease has not been established.
