Saffron, also known as crocus, is the same plant. Saffron enters the heart and liver meridians and is sweet and flat in nature. It can invigorate blood circulation and eliminate blood stasis (promoting blood circulation and eliminating blood stasis in the body), cool the blood and detoxify the toxin (referring to the treatment of blood-heat and toxicity), and relieve depression and tranquilize the mind. It is used in treating menstrual obstruction, post-partum stasis, warm-heat and poisonous spots (warm-heat and poisonous evils encroaching on the body resulting in spots and plaques on the skin), melancholic ruffling, and palpitation and frenzy. If the patient has depression in heart and chest due to worrying, or if the patient has a stuffy heart, chest, stomach and epigastric region, saffron can be taken to treat the depression in heart and chest; if the woman has menstrual closure, or if the patient has abdominal pain due to stasis of blood in postpartum, or if the patient has vomited and vomited blood, or if the patient has been injured by falling or falling, saffron can be used to invigorate blood circulation and remove the stasis of blood, remove stagnant blood from the body and encourage the generation of new blood. Since saffron is strong in activating blood circulation, it should be used with caution in pregnant women, women with excessive bleeding during menstruation and patients with bleeding disorders. If you feel unwell, use saffron under the guidance of a physician and do not take it on your own to avoid adverse consequences.
