Crocus sativus is sweet in flavor, flat in nature, and belongs to the heart and liver meridians. Crocus sativus is a traditional Chinese medicine, which is the dried stigma of Saffron in the family of Iridaceae. Its functions are to activate blood circulation and remove blood stasis (promoting blood circulation and eliminating blood stasis in the body), to cool the blood and remove toxins (referring to the treatment of blood-heat and toxins in the body), and to relieve depression and tranquilize the mind. Clinically, it is mainly used to treat menstrual obstruction and impediment in the abdomen, postpartum stagnation, warm-heat poisonous spots (warm-heat poisonous evils invade the human body resulting in spots and plaques on the skin), depression and congestion, and palpitations and frenzy. Although Crocus sativus has many effects and functions, it is not suitable for pregnant women because of its strong blood-activating effect, so as not to cause discomfort. If the patient has a need for medication, it is recommended to go to the hospital in a timely manner after consultation with a specialist, follow the doctor’s instructions for medication, to avoid blind use of medication or increase the dosage, which may cause discomfort.
