General The patient has a normal menstrual cycle with a duration of 7-10 days, low menstrual volume and a dark color at the beginning. Back pain during menstruation. She is usually cold and has cold hands and feet. Her bowels are regulated and her stomach is not upset. Treatment Radix Angelicae Sinensis Sibiricus Tang with lotus leaf 10g, mugwort leaf 10g, raw earth charcoal 20g, cypress leaf 10g, cistanches 10g, comfrey 10g, motherwort 20g, orris 10g, red peony 10g, chuanxiong 10g, salvia 30g. The patient complained of dry stools once a day, and added 10g of fire hemp seed to the above medicine for another week. The erythema almost completely receded and the face looked less red, but there was still a small amount of capillary dilation. The patient was cured on the third visit according to the original prescription for 7 times, with follow-up. Since the local manifestation of facial hormone dependent dermatitis is red and the patient feels burning, the common treatment by doctors would be to think that the blood is hot and to cool the blood to invigorate it. In the case of this patient, after careful questioning, the patient had a long duration of menstruation with low volume and lumbar pain during menstruation. The patient’s coldness, coldness in the hands and feet, pale, dark red tongue, white greasy moss, and weak pulse are all indicative of Yin-Cold. The patient is analyzed as Yin-Cold is strong inside and Yang-Heat is floating outside, and Yin and Yang are not in harmony. We added lotus leaf to raise yang on the basis of warming the meridians and clearing the veins with danggui shuihui tang, and orris to promote the dissemination of yang energy. Radix Bupleurum, Comfrey, Salviae Miltiorrhizae, and Radix et Rhizoma Glycyrrhizae cool the Blood and detoxify the internal heat. Cistanches nourish the kidneys, and Yimoucao nourishes the blood to support the body and strengthen the root. This treatment characteristic of “combining cold and heat” fully reflects the discriminatory thinking of TCM.
