Saffron and Pregnancy
Although eating foods that contain saffron is probably safe, it is not considered safe for pregnant women to use saffron medicinally. Just because saffron is a "natural" product, this does not automatically mean that it is safe during for pregnant women. Doses of 10 grams or more have been reported to cause contractions and even miscarriages.
Saffron is best known as a spice, although it is sometimes used medicinally as an herbal supplement. While a normal intake of saffron through dietary means is considered safe for most people, including pregnant women, large doses could be dangerous during pregnancy. Medicinal use of saffron is not considered safe for pregnant women. High doses (10 grams or more) have reportedly caused contractions and even miscarriages.
In some cultures, saffron is taken during pregnancy to improve the complexion of the infant. There is no evidence to suggest that this really works, but it is probably not harmful if the saffron is limited to small amounts.
However, keep in mind that just because other pregnant women have used a natural product without problems, this does not mean that it is safe. It takes a large group of pregnant women taking a particular medication or herb to see if it increases the risk of problems, such as miscarriages or birth defects, as these problems often occur infrequently.
If you are pregnant, it is always a good idea to talk to your healthcare provider before taking any medication or supplement. The two of you can consider the possible risks and benefits of using saffron in your particular situation, as well as any other treatment alternatives.
