Lei, female, 34 years old, was seen on January 27, 2015, and the patient reported coldness in her lower back for half a month. The patient had a pedestrian abortion half a month ago, after the operation, the back and waist cold, cold site is not fixed, but appears wandering, the stool is not formed in large amounts, when relieving the stool laborious, often once every four or five days, urine clear and long, dizziness of the head, like to sigh, tongue light red, side of the teeth marks, moss white greasy, pulse sunken and thin. The diagnosis is: coldness of the back and waist. The diagnosis is: deficiency of Yang in the spleen and kidney and wind energy. The formula is based on Ling Gui Zhu Gan Tang combined with Han Xia Hou Pu Tang: 15 g of Fu Ling, 15 g of Atractylodes Macrocephala, 10 g of Gui Zhi Jian, 5 g of Roasted Licorice, 10 g of Fa Han Xia, 10 g of Chuan Hou Pu, 10 g of Perilla leaf, 10 g of ginger slices, 10 g of Angelica sinensis, 20 g of Cistanches, 10 g of Sheng Ma, 10 g of Citrus aurantium, 7 doses. He came to the clinic on December 8, 2015 due to pre-menstruation, and all the symptoms were cured after the described former medicine. Note: People with Yang deficiency are generally prone to cold back, and the cold back in patients with phlegm drink is different from the cold back in Yang deficiency, which is described by Zhongjing as “when there is retention of drink under the heart, the person’s back is as cold as a palm.” This patient has a deficient spleen and kidney yang constitution, plus improper post-abortion care, suffering from wind evil, so the coldness of the lower back is wandering, because the wind is good at moving several changes. In addition to the emotional disorders, and therefore like to sigh, qi is not smooth, then the conduction is not conducive, so the stool does not pass. If the spleen and kidney are deficient and the clear orifices are not nourished, then the head and eyes are dizzy; if the yang energy is weak, then the urine is clear and long; the tongue is pale with white fur and the pulse is sunken. Professor Liu Zhilong used Ling Gui Zhu Gan Tang to warm Yang, strengthen the spleen and dispel dampness because the patient’s tongue was white and greasy, and to treat the wind because the patient’s wind energy was superior. Although there is only one medicine for the kidney, Cistanches is the most used in the formula, which can warm the kidney and benefit the essence, warm the waist and moisten the intestines, one thing and several uses, the medicine is not more, but in the power of specialization.
