The difference between liver deficiency fire and real fire is that liver deficiency fire is a deficiency of liver and kidney yin (deficiency of yin in the liver and kidney), and liver yang is over-exuberant, which belongs to the upper and lower part of the body (the upper part of the body manifests headache, irritability, etc., and the lower part of the body manifests lumbar acidity, frequent urination, etc.), and the deficiency and reality are mixed (there are both deficiency and reality in the human body); liver real fire is the fire of the liver meridian, and the pathology is purely a real evidence. The difference between liver deficiency fire and solid fire is that liver yang hyperactivity must be identified with liver fire blazing evidence. The two certificates in the mechanism and symptoms of the two have similarities, both have Yang heat hyper inverse pathological changes, so all have the head and face of Yang heat symptoms, such as dizziness, swelling and pain, red face and eyes, deafness and tinnitus, accompanied by irritability, insomnia and dreaming, such as the symptoms of mental restlessness. The difference between the two is that the liver fire blazing syndrome is the liver meridian fire, gas fire upward, the disease is shorter, the disease is more acute, the nature of the disease is purely real, so the mouth is bitter and thirsty, dry urine yellow, earache and pus, two burning pain, tongue red with yellow fur, and the pulse is characterized by stringy. Liver and kidney yin deficiency, liver and kidney yang hyperactivity syndrome, longer course of the disease, the disease is slower, is the upper fullness of the lower part of the deficiency, mixed solid and virtual, so the waist and knee soreness (waist and knee soreness and weakness), head heavy and feet light, tongue red, less fluid, pulse string fine as the clinical characteristics. The presence of liver fire, need to actively consult the doctor, in accordance with the doctor’s instructions for reasonable treatment.
