Many acute ophthalmologic diseases in clinical practice are often treated with the lower method and often receive satisfactory results. There are many cases of external ophthalmopathy that belong to real fire and heat toxicity, but the clinical evidence should first identify whether the lower method is applicable. If the patient also has symptoms of irritability, constipation, or no constipation and the eye belongs to the heat and poison, as long as the patient’s body is strong, can be used under the method of straight fold its potential. When the patient has been released many times, the eye redness and pain, photophobia and shyness and other symptoms can often be immediately reduced, and receive immediate results. It is a very fast and effective method to reduce fever, so it is called “kettle bottom firewood” method. Although the eyes live in the head, but its connection through the meridians, and the five internal organs have a very close relationship. For example, the meridian of the stomach starts under the eyes, enters the teeth, rings the lips, follows the throat, the lower diaphragm, and belongs to the stomach. The accumulated heat in the stomach and intestines can directly disturb the eye orifices through its meridians. If the heat of the stomach and intestines is removed, the heat of inflammation can be directly reduced, so that acute symptoms of eye diseases, such as red eyes, swollen cells, gnarled veins, hot tears like soup, cataracts covering the eyes, headaches like splitting, or even pus filled eyes, can be quickly controlled. Ophthalmic diseases, especially external eye diseases, are often caused by real fire and heat toxins. Zhang Zihe, a famous doctor of the Jin Dynasty, said, “The eye is not sick if it is not due to fire.” Although this statement is not too one-sided, but illustrates the eye disease is a real heat evil poison for many people. The “bottom of the kettle” belongs to the cold method, which is a cold and laxative drug to pass the stool, thus diarrhea out of the body of real heat treatment. This method can not only remove the dry stool in the intestine, but also cleanse the actual evil heat poison from the stool, so it is one of the important methods to treat external eye disease.

Case 1: Chen ×, male, 10 years old, clinic number 79607. The child visited the clinic on August 22, 1964 for 10 days with red eyes, swollen mucous, photophobia and tearing.

Case 2: Zhao ×, female, 14 years old, clinic number 63317. The patient suffered from sclerenchyma several times from 1961 to 1963 and was treated at a hospital in Beijing for one week on 9/26/63 for redness, pain, photophobia, and tearing in the right eye. At the time of consultation, the right eyelid was moderately red and swollen, with spasm, redness around the wind chakra holding the chakra, blood all over the white eye, a redder tongue, thin white fur, and a fine pulse. The evidence is that lung heat rides on the liver meridian, heat toxin is congested, aiding blood flow and stagnation of the vasculature, hence the redness, swelling and pain are severe. He was given medicine to clear the wind and heat, calm the liver and brighten the eyes, such as wind, thorny mustard, Su Ye, papaya, scutellaria, forsythia, cassia seeds, jiao gardenia, mulberry bark, stone cassia, etc. He took even seven doses and used rhinoceros yellow powder to spot the eyes, the effect was not too obvious, and the symptoms were basically the same as before after seven days. Because of the realization that the lung and large intestine phase, diarrhea large intestine that can be diarrhea lung heat, with the “bottom of the pot” method of effect is not faster? The above formula was taken internally for five payments, and I felt that all the symptoms were reduced, the bowels were clear, and the blood vessels on the white eyes were congested and the redness of the embrace had been reduced, because the agent of stepping down could not be taken for a long time, and then it was changed to the agent of dispelling wind and cooling blood. The patient felt that all the symptoms were reduced, the bowel movements were smooth, the blood vessels on the white eyes were congested and the redness of the embracing circle was reduced. The above-mentioned agents should only be taken temporarily, not for a long time, so as not to damage the spleen and stomach, which will cause the depletion of the righteousness and the disease to linger. In case you take the above laxatives and have too much diarrhea, you can drink a bowl of cold boiled water and the diarrhea will stop immediately, so there is no need to be afraid. After the diarrhea, then combine with the specific situation, weigh the symptoms and priorities, and adopt appropriate treatment methods. In short, the treatment of disease is to adapt to the evidence, not to be paranoid about one end.
