There is no lichen planus in the contraindications of saffron, but saffron has no therapeutic effect on lichen planus. Saffron is sweet in flavor, flat in nature, and belongs to the heart and liver meridians. Its effects are to invigorate blood circulation and eliminate blood stasis, and to disperse depression and open the knot. It is commonly used in the treatment of dysmenorrhea, amenorrhea, postpartum abdominal pain, vomiting blood, depression, chest and diaphragm congestion, fever, palpitations, trance and other symptoms. Its adverse effects are not clear. Note that pregnant women should not take. Drinking saffron for lichen planus is not against the contraindications of saffron, but from the viewpoint of the efficacy of saffron, drinking saffron has no therapeutic effect on lichen planus. It should also be noted that saffron in water is limited in its efficacy, and can not be used as a substitute for medication. If you need to use drugs, it is recommended to go to the hospital in time, under the guidance of a professional physician for treatment, not self-medication, so as not to delay the condition.
