Deep needling, especially in thin subjects may penetrate the liver on the right side and the peritoneum on the left.


Classical Needling:

"The Shaoyin usually has little Blood and much Qi" (Su Wen 素問 ch. 24) implying this channel should normally be needled.
"The foot Shaoyin is to be pierced 2 fen deep and remain inserted for three exhalations" (Ling Shu 靈樞 ch. 12).
"It is needled to a depth of five fen and moxaed with five cones" (Huangfu Mi 皇甫謐, 3rd Century, Zhenjiu Jiayi Jing 針灸甲乙經).

Jeffrey Yuen translates Youmen as "Gate to the Mysterious" as it is the final point along the Kidney channel before the Chong Mai moves into the Heart and diffuses Qi into the chest (Yuen, 2005, The Eight Extraordinary Vessels, p.49). The next points along the Kidney channel, when located at 0.5 cun from the midline, he calls the front Shu with similar ability to influence the Zangfu as the back points although only the Yin organs are represented.



The "Nine Flowers" is a combination of points that aims to open the Diaphragm and allow new life to enter (Jeffrey Yuen protocol, learned via discussion group).



Shokanten points are often used in Japanese acupuncture to treat conditions arising from a psycho-emotional background. This point affects the Middle Jiao, Shaoyang and the eyes and ears.
