excessive fire due to yin deficiency belongs to deficiency fire, which is mostly caused by deficiency of essence and less blood, severe injury of vaginal fluid, and hyperactivity of yang due to yin deficiency. Generally speaking, internal heat due to yin deficiency is more common in general signs of deficiency heat. However, yin deficiency and excessive fire are often concentrated in a certain part of the body. For example, toothache, sore throat, dry mouth and lips, hot flashes due to bone steaming, zygomatic redness, etc. caused by yin deficiency are all caused by deficiency fire. In a word, the endogenous pathology of fiery heat is nothing more than both ends of deficiency and excess. The actual fire, mostly due to the excess of yang, or because of evil stagnation, or because of five aspirations to turn fire. Its disease is rapid and the course of disease is short. It is characterized by strong heat, red face, thirst and cold, Huang Chi in urine, constipation, and even mania, coma, red tongue with yellow and dry fur, and rapid pulse. Deficiency fire is mostly caused by deficiency of essence and blood, deficiency of yin can not control yang, and deficiency of yang is caused by hyperactivity. The disease is slow, and the course of disease is long. Its main clinical features are vexation and fever, red cheekbones in the afternoon, insomnia and night sweats, dry mouth and throat, dizziness, tinnitus, red tongue with little fur, and rapid pulse.

(2) Take more water to supplement the loss of water when the body gets angry and gives off heat, and promote metabolism, promote fluid production and diuresis, and accelerate the excretion of toxins and heat. (3) Do not eat spicy and hot food, such as pepper, dried ginger, raw garlic, pepper, strong tea, tobacco, spirits, coffee, green onions, etc., so as not to generate heat to help fire, burn body fluids and aggravate the illness. (4) Those who actually burn should eat more cold and heat-clearing foods, such as mung beans, eggplant, wax gourd, loofah, bitter gourd, etc., and avoid foods that help yang to promote heat, such as leeks, mutton, dog meat, sparrow meat, sorghum, longan, cherries, apricots, etc. (5) People suffering from asthenic fire should pay attention to supplementing nourishing yin foods such as tremella, lily, mulberry, clam meat and turtle meat, and should not eat more cold fruits and all kinds of cold foods. (6) We should pay attention to "dialectical feeding", analyze the excess and deficiency of internal heat, carry out targeted diet therapy, and choose foods that clear away heat and reduce fire. If we do not distinguish between real fire and virtual fire, we will often not get good curative effect, and sometimes even aggravate the condition, "burning oil on the fire." This is the reason why some patients do not pay attention to dialectical feeding and blindly diagnose and treat themselves, and the effect is not good. The main cause of oral ulcer is "excessive internal heat", but "fire" can also be divided into deficiency and excess.

Recommended drugs: Niuhuang Jiedu Tablet, Sanhuang Tablet, etc. You can also use 1 grams of bamboo leaves, 3 grams of reed roots, 5 grams of rhubarb and 1 ml of water. After decocting for 1 minutes, pour out the decoction, add white sugar and let it cool, and take it twice in the morning and evening. This kind of medicine hurts the stomach due to bitter cold, so you should pay attention to it when taking it, and stop taking it as soon as you recover. The surface of oral ulcer due to deficiency fire is white, with a small number and dull pain. It is easy to be accompanied by symptoms of yin deficiency such as upset insomnia, dry mouth, and heart heat in hands and feet.
