Abstract: The patient reported difficulty falling asleep at night for about six months and often waking up even after sleeping, while always feeling weakness in the waist and knees, cold legs and feet, memory loss, poor concentration, and a particularly pronounced feeling of weakness and lethargy. This evidence often appears to be true yin deficiency, which leads to the formation of this physical change over time. Chinese medicine treatment should make the heart fire sink and mobilize the kidney water to help. The patient can sleep normally in a quiet state. The patient’s sleep quality was very poor in the past six months. The patient’s sleep quality has been very poor in the past six months. He often stays up late at night due to his work, usually has an irregular diet, hunger and satiety, emotional anxiety, fatigue, poor energy, memory loss, fatigue and tiredness, frequent ulcers in the mouth, weakness in the waist and knees, fear of cold legs and feet, frequent thin stools and frequent urination, especially in winter. He had been taking related drugs with poor results, and now he wants to improve his physical condition and sleep through Chinese medicine system conditioning. The patient’s symptoms and the condition of the tongue and pulse are considered to belong to the heart and kidney disorder. The patient was treated with Jiaotai Pill and Licorice Diarrhea Heart Soup according to the TCM system of identification, and the method of traffic between heart and kidney was applied. At the second consultation, the patient’s tiredness and fatigue were slightly reduced, his mouth ulcers improved and the number of new ulcers decreased significantly, he slept lightly but was able to sleep, and his fear of cold stools was still present. At the third consultation, the patient’s mouth ulcer has improved, appetite has improved, stool can be formed, sometimes scattered, energy status has improved, sleep 3-5 hours, general condition is good, fear of cold in the waist and legs still exists, adjust the prescription, with Jiaotai Pill plus sour date palm and lily of the valley to continue consolidation treatment. At the fourth consultation, it can be seen that the tongue coating has been basically normal, but it is still necessary to continue consolidation. The patient had been treated for 2 months from the initial consultation to the last consultation. After the TCM evidence-based treatment, the patient’s symptoms of discomfort caused by heart and kidney disorder had improved greatly, and the patient could basically sleep for 5 hours at the last consultation. Because the patient had stayed up late for a long time in the past, the essence and blood were deficient, so the lumbar soreness and weakness still need to be consolidated later. IV. Precautions We are glad that after treatment, the patient can sleep normally in a quiet state. Self-adjustment of mind has a great effect on the heart and kidney disorder. Often anxiety and depression can easily lead to hyperactivity of heart fire, which can aggravate insomnia and dreaminess, irritability, or mouth ulcers, etc. Adjustment of life and rest time and regular living condition is very important for the adjustment, if often stay up late, the symptoms of yin and yang disorder will be more deeply obvious. And regular diet and light diet are also important. Normal spleen and stomach transportation function and normal qi lift and lower will be twice as effective for treatment. Proper exercise and harmony between Ying and Wei can make the excessive heart fire dissipate itself. Finally, quitting smoking and limiting alcohol are also very meaningful for the prognosis treatment of the disease. V. Personal insight The patient is usually anxious and often stays up late, which leads to depression and easy accumulation of fire and depletion of true essence, so the waist and knees lose nourishment, resulting in soreness and weakness of the waist and knees, the fire does not descend, and the cold evil grows inside, so the legs and feet are cold. Treatment requires drawing the upper fire to the lower jiao to warm the kidney water, and the kidney water to help the heart fire to clear the heart and calm the mind. Once the heart and kidney do not cross the evidence, the symptoms are prone to recurrence or aggravation, and also prone to other symptoms caused by plant nerve dysfunction, which are intricate and complex, so early treatment should be given so that the disease evil does not go deeper.
