《黄帝内经·灵枢·岁露论》
如果到了月亮亏缺的时候，海水向东涌盛形成大潮，这时人体气血相应虚弱，体表卫气衰退，外形虽然如常，但肌肉消减，皮肤弛缓，腠理开泄，毛发残脆，肉理疏薄，烟尘污垢不容易附着于体表形成保护，在这个时候，若遇到贼风邪气的侵袭，就容易深陷入里，发病也急暴。
至其月郭空，则海水东盛，人气血虚，其卫气去，形独居，肌肉减，皮肤纵，腠理开，毛发残，膲理薄，烟垢落，当是之时，遇贼风则其入深，其病人也卒暴。
If the moon is waning, the sea water flows eastward and forms a large tide. At this time, the body's qi and blood are correspondingly weak, the body's surface qi is declining, the appearance is normal, but the muscles are reduced, the skin is relaxed, the pores are open, the hair is brittle, the muscles are thin, and the smoke and dust are not easy to adhere to the body surface to form protection. At this time, if you encounter the invasion of thief wind and evil qi, it is easy to penetrate deeply, and the onset of the disease is also acute.
