When the body temperature is about 37.5 ℃, the dosage can be reduced gradually until the symptoms disappear. According to the observation, after taking banana root juice, the patient first had diarrhea and increased urine volume, and then the high fever decreased rapidly, and his condition improved. There is no problem of dehydration due to the increase of water excretion. Because the problem of high fever is solved, the danger of convulsion and respiratory failure can be avoided or reduced, and the disease can be transformed. If there is no diarrhea and abdominal distension, the fever will be difficult to decline and the disease will worsen. Therefore, during the period of taking banana root juice, hibernating drugs and atropine drugs should not be used, so as not to inhibit gastrointestinal peristalsis and cause abdominal distension. If there is no diarrhea after taking medicine, enema or oral administration of sodium sulfate 1-2 times a day can be used. When using this method, we should also cooperate with physical cooling to control the high heat quickly. 117 cases were treated, 110 cases were cured, 1 case had sequelae and 6 cases died.
