Yu, female, 15 years old, student. Complaint: abdominal pain for 2 days. The patient has been suffering from menstrual fluid for 2 days, with hidden pain in the lower abdomen and stomach, eating and drinking, and cannot rest at night; her voice is low, her face is white, her lips are pale, and her tongue is fat and blue with a dull white coating. I think, dysmenorrhea is common in the clinic, not only qi stagnation, cold clotting, blood stasis and blood deficiency, look at her face white light white, tongue blue dull moss white can be known as cold clotting blood stasis, to “less abdominal by stasis soup” can be effective. The woman is 14 years old and has irregular menstruation with moderate volume and pale color, and pain in the lower abdomen, which can be relieved after rest and local heat application, but this time the pain is especially severe. Her pulse was smooth and strong, and she asked if she had phlegm in the past. A: He used to vomit white thick sputum in the morning, and in the past half month, he not only vomited sputum in the morning, but also had vomiting feeling after three meals, and vomited white sticky sputum for several mouthfuls before he was relieved. Hearing this, what I thought before is inevitably out of conjecture. The “Golden Guide to Medicine” begins with the following statement: “Look with your eyes, hear with your ears, ask with your words, cut with your fingers, understand the way of diagnosis, know the root cause of the disease, and be able to combine the color and pulse, you can be all right.” Clinical diagnosis, even after the four diagnoses together, still need to be carefully identified as appropriate, and in case of disease without detailed examination that is based on self-assumptions, is indeed a big taboo for doctors! The prescription was based on the combination of the four diagnoses, the dysmenorrhea should be identified as phlegm-damp stagnation and cold stagnation, and the formula was based on the combination of Cangfu Guiding Phlegm Tang and Liangfu Wan, with the addition of four slices of fresh ginger and five jujubes. 4 doses, decoction, 1 dose daily. After taking 2 doses, the patient’s pain in the epigastric region was removed, and the painful sensation in the lower abdomen was also reduced. After taking 4 doses, her diet improved and she slept peacefully at night. Later, after taking more than 20 doses of this formula intermittently, all the symptoms were removed. Six months later, we learned that the patient had regular periods, moderate menstrual flow, and no special discomfort during menstruation. More than a thousand years ago, Zhong Jing’s master criticized the medical attitude of “relative to the need, then the soup and medicine”, as the saying goes, the way of medicine is difficult, the way of medicine is dangerous, so I wrote this medical discourse, one is used to self-reflection; two is to encourage with fellow doctors.
