Taking too much saffron infusion may lead to adverse reactions such as bleeding and heavy menstruation. Saffron is a kind of traditional Chinese medicine, the dried stigma of saffron in the family of Iridaceae, with the effect of activating blood circulation to dispel blood stasis, dispersing depressions and opening knots, and cooling the blood to remove toxins (referring to the treatment of blood-heat and toxin embodiment). It is used for the treatment of dysmenorrhea, menstrual closure, menstrual disorders, post-partum discharges, pain in abdominal masses, bruises, melancholy and lumps, palpitations, warm spots, measles and other conditions. Note that pregnant women should not be used with caution. Saffron is strong in activating blood, and should not be taken in excess for a long period of time. If the patient has the need for medication, it should be used under the guidance of the doctor’s diagnosis, and should not be used blindly on its own, so as not to cause adverse consequences.
