Drinking saffron during pregnancy can easily lead to miscarriage. Saffron is a medicine that is particularly effective in activating blood circulation and removing stasis, and is more effective for injuries or postpartum bruising because it induces uterine contractions. But because the effect of inducing uterine contractions is so obvious, taking saffron during pregnancy can cause the uterus to contract and become excited, which can induce contractions that lead to bleeding and cause stomach pain. Therefore, you should not take saffron during menstruation or when you are pregnant. Saffron is contraindicated during pregnancy, and pregnant women must not use saffron. Other medications or foods that have blood-activating effects should also be avoided as much as possible to avoid increasing the risk of miscarriage and bleeding, so as not to increase the risk to the baby and the pregnant woman.
