肾脏主管腰部和下肢。肾经虚弱时容易感受风邪和寒湿之气。体内会有水液停聚，风水相互搏结，浸渍于肾脏，导致肾气内着，不能宣通。
因此出现腰部和小腹寒冷沉重，感觉像带着五千枚铜钱一样，好像坐在水中，身体形态如同水状但不口渴，小便通畅自如，饮食正常。时间久了会转变为水病，这是因为肾受湿邪所致。

用橘核微炒去壳研为末，酒调服即愈。体内有水液停聚受伤，被风冷所乘，久而不愈，使人成为水病，称为肾着，适宜服用。
The Kidney governs the waist and lower limbs. When the Kidney meridian is deficient, it is susceptible to Wind-Cold pathogens. Accumulation of fluid occurs internally; Wind and Water Qi contend with each other, infiltrating the Kidney. The Kidney Qi becomes stagnant internally and cannot circulate freely.
Consequently, coldness and heaviness are felt in the waist and abdomen, as if carrying five thousand coins, resembling sitting in water. The body appears edematous but there is no thirst, urination is normal, and appetite remains unchanged. Over time, this may transform into a Water Disease (Shui Bing), due to Dampness affecting the Kidney.
