Notes:
This point is also on the 3rd trajectory of the Chong mai connecting the Chong with the Du (Yuen, 2005, The Eight Extraoridinary Vessels).

It would also be on the trajectory of the Dai mai as described in the classical texts such as the Nei Jing and Ling Shu where considered the Dai mai as simple a circle around the waist level to Shenque Ren-8 and Mingmen Du-4 instead of the traditional points (ibid.).

Avicenna describes cupping at this point in his treatise On Cupping:

"Cupping on the loins helps in cases of boils, scabies, and pustules of the thigh; gout, haemorrhoids, elephantiasis, gas of the bladder and uterus; and itching of the back. The cupping would have the same effect whether the cupping was with heat or without, or with slitting (scarification) or without. The cupping with slitting is more effective in non-gaseous situations, and the one with slitting is better in disintegrating the cold gas and removing it form the loins and from any other location." (Aspects of Treatment According to General Diseases, 22nd section in Abu-Asab, Amri & Micozzi, 2013, Avicenna's Medicine)

There are several ambiguities in this paragraph such as the exact location of the "loins", technically described as the region between the lowest rib and the hips, at this point, but also often in literature indicating the groin. Second, both examples suggest "with slitting" when one ought to be without, but without the original text (and a crash course in classical Arabic) then I cannot determine which is with and which is without.
