Saffron is used mostly as a spice but it also finds use as a medical supplement. The health concern from taking saffron for pregnant or other women arises mainly when it is overused. Large doses can be particularly harmful during pregnancy. In general, it is considered safe to take saffron in doses smaller than 10 grams even during pregnancy. Higher doses have been known to cause contractions and even miscarriage.
In some countries of the world, saffron is believed to have an effect on development of skin in foetuses. It is held that saffron can lead to lighter-skinned babies. There has not been any research carried out to prove or negate this but those who believe in it claim its efficacy. Moreover, they would vouch for its safety when taken during pregnancy. That is because they are wise enough to take it only in small quantities.
As far as its safety for women who do not take it, unanimous medical opinion permits dosage less than 10 grams a day. The final word on its efficacy and optimum dosage can only come when it is tested on several women to see if it increases the risk of pregnancy complications, birth defects or miscarriages.
Saffron being a natural product should not lead all women to believe that it would be safe for them. Consult your healthcare provider to get an understanding of the benefits and risks associated with taking saffron in your condition.
