Patients: for many years have been feeling thirsty and dry mouth, dry skin, dry and cracked lips and heels; gums often vaguely painful, eating warm foods such as aquatic products, dried fruits, cattle and sheep, sweet or spicy foods, gum pain increases, and constipation; often accompanied by dry eyes and sore brow bones. And the head is especially afraid of wind blowing, even the breeze head will be cold and painful, so you must wear a hat outdoors, the cool breeze in the morning and evening in summer and the warm breeze of air conditioning in winter will also be head cold. Both shoulders are often cold, and the back is often cold. Knees also have cold soreness, and even the lower limbs make cold over the knees. Night sweats often, the upper half of the body is hot and the lower half is cold; often there is a lot of sweat on the neck and chest, but the lower half is cold. In the daytime, in the warm air conditioner, the face is hot and red, but the body is not warm, and even the shoulders are cold. I had taken western medicine for a month, but there was no obvious improvement; I had also taken Chinese medicine, but always had toothache and constipation, and the doctor said he could not find the way. I feel that my body is getting weaker and weaker. After seeing many Chinese doctors, they said that I was weak but not tonic, and two contradictions, fire and cold, were concentrated in me, so it was difficult to write prescriptions and regulate. Chinese herbs like Radix Codonopsis, Radix prunus ginseng, Radix et Rhizoma ginseng, Radix Angelicae Sinensis, Radix Astragali, and so on, get on fire when used in small amounts, leading to toothache and constipation. Recently, I had immunological tests at the Immunology Department of Renji Hospital, and no problems were detected. I would like to ask for a solution to the conflict between fire and fear of cold, to eliminate toothache, constipation, and to regulate the functions of the liver, intestines, and stomach. The First Hospital of Nanjing, Department of Traditional Chinese Medicine, Zhao Wenbin: Your disease is actually clinically common in many patients, manifesting as upper heat and lower cold, the condition is more complicated than the general disease, but still treatable. The root cause is the weakness of the kidney yang. You must help the yang energy to make the false yang dive down, the yang dive down, in order to yin and yang tone, yin and yang harmony will be on fire and fear of cold symptoms will be eliminated.
