Lu-5 ChĭZé 尺泽 Cubit Pool
【Name explanation】1) 尺, Chĭ was an ancient chinese unit of length based on the distance between the wrist and the crease of the elbow; 泽, Zé, means pool or a deep place where water gathers. Lu-5 is the Lung channel He-Sea point and corresponds to the element water. The hand Tai Yin channel Qi flows here like water gathers in a pool, and Lu-5 is located one Chi from the wrist in a depression in the transverse crease of the elbow, therefor it is called Cubit Pool. It treats inhibition of Lung Qi, phlegm-heat congesting the lung and also clears toxic heat in the blood.
2)尺, is a fusion of the character“尸”(body) and “乙” (which looks like a flexed elbow), meaning the forearm. 泽, a depression or hollow where water gathers. The name comes from the point localization.

Repletion is treated by draining the child, therefore dispersing this point clears and drains lung heat, disperses and descends Lung Qi. External evil raid the Lung, phlegm-heat inhibits the Lung, evil heat and Yin vacuity lung dryness etc causing impaired diffusion and descending of the lung, abnormal Qi dynamic etc can be treated with Lu-5.
2. Cool the blood resolve toxin: The elbow is a big joint where a lot of Qi and blood is streaming, therefor bleeding Lu-5 clears blood heat and evil toxins. It treats blood heat-toxin causing summerheat stroke, acute vomiting and diarrhea, child wind-fright etc.

【Note】Lu-5 is the He-Sea point of the Lung channel, where channel Qi penetrates deeper to enter the Lung like a ”floodgate”. If external evil enters this channel, and is not diffused, this is the place it has to enter the interior. When external pathogens are not treated in time and enters the interior Lu-5 can hinder it’s passage and transmutation.
