From Sanwu, Badong, and various mountain commanderies and counties in the south, in places such as valleys and stream sources, there is a disease called Water Poisoning. This illness occurs or worsens in spring and autumn. It is also known as Zhong Shui (Water Strike), Zhong Xi (Stream Strike), Zhong Sa Su Hai (a local term), Shui Bing (Water Disease), and Xi Wen (Stream Fever). Nowadays, people call it "Zhong Xi" because its symptoms are similar to those of She Gong (Arrow Bug), so it is generally referred to as "Xi" (Stream).

A pulse that is deep, fine, and slow indicates a Yin syndrome, specifically Ci Xi (Female Stream), which is difficult to treat. To confirm if it is indeed Zhong Shui, check if the fingers of the hands and feet are cold. If they are not cold, it is not this condition. The coldness may extend one cun, up to the wrist, or up to the elbow and knee. Coldness extending two cun is mild; reaching the elbows and knees is severe.
Another method states: Boil several dou of hot water, add four sheng of garlic, crush it, and put it into the water. This is effective. Strain out the dregs, adjust the temperature to be suitable, and bathe in it. If red spots appear on the body, it confirms the diagnosis.
Another description states: Sores appear at the affected site, resembling black dots surrounded by redness, looking like chicken eyes. Lesions on higher parts of the body are difficult to treat, while those on lower parts are easier. There are no other differences. The symptoms include feeling alternating chills and fever, headache, stiffness and spasm of the waist and back, cold hands and feet, chronic cough with drowsiness, improvement in the morning and worsening in the evening. However, treating Xi Bing does not require garlic baths or examining sores in the lower body. When this condition becomes critical, it may also cause diarrhea and bleeding from between the teeth. If the heat intensifies, it leads to restlessness in the heart and abdomen, anorexia, and delirious speech. Some patients pass bloody matter resembling rotten liver. Death may occur within ten to twenty days due to unpredictable causes, resulting from insects eroding the five zang organs and injuring the anus.
It is also said that if Xi Bing does not heal, flying insects enter the body, residing in the skin or between the abdomen and ribs, with varying numbers. This corresponds to the aforementioned insect erosion of the five zang organs and lower body issues. If the insects attack the zang organs, death ensues. The methods used locally to ward this off are similar to those for She Gong.
Formulas for Treating Water Poisoning:
Burn the root of Wu Jia (Eleutherococcus senticosus / Acanthopanax gracilistylus) to ash, grind into powder, and take 2 qian mixed with wine or water. Drinking the juice of crushed leaves is also good.
