This point would also be on the upper trajectory of the Chong mai in Jeffrey Yuen's descriptions (Yuen, 2005, The Extraordinary Vessels).

In Tung acupuncture two points called Shui Tong, Water Through, and Shui Jin, Water Metal, are located near this point. Shui Tong is located 0.4 cun below the outer corner of the mouth and Shui Jin is located 0.5 cun medial to Shui Tong. They are indicated for Wind-Cold-Damp Bi of the lower back, Kidney deficiency and breathing difficulties, presumably due to a failure of the Kidneys to grasp Lung Qi (Chu, 2015).

Avicenna describes venesection at this point in his treatise On Venesection:

"The labial veins are four, two for each lip. Their venesection is beneficial in cases of mouth sores, stomatitis, and painful, swollen and receding gums, as well as haemorrhoids and their cracks." (Aspects of Treatment According to General Diseases, 21st section in Abu-Asab, Amri & Micozzi, 2013, Avicenna's Medicine)

Reference Notes:

Basic information on location, needle depth, TCM actions, indications and combinations is taken from Deadman et al (2001): A Manual of Acupuncture with additional anatomical information researched by reference to Gray's Anatomy (38th Ed., 1995) unless otherwise referenced. Images were found on acupunctureschoolonline.com and can be traced back to Claudia Focks (2008) Atlas of Acupuncture originally. I cannot claim any credit or rights over them.
