    Notes:
    Galen recommended arteriotomy "behind the ear" and so probably at Yifeng SJ-17, or on the occipital artery at this point or Luxi SJ-19 for scotomatics (blind spots) and people with "chronic hot and spiritous pains in the head" (Brain, 1986, Galen on Bloodletting, p.97).

    Aretaeus performed arteriotomy in front (probably Taiyang) and behind the ears for epilepsy (ibid.: p.97, footnote).

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

    "There are three small veins (posterior auricular veins) located behind the ear where it meets the hair. One of the three veins is more visible and is venesected at the start of water and vapour accumulation in the head coming from the stomach; for this reason it is beneficial in the case of ear and back-of-the-head sores, as well as in head disease. Galen rebuffs the notion that venesecting the veins behind the ears causes sterility [lowering of libido] as sought by reclusive individuals.
    ....
    The arteries behind the ears, the posterior auricular arteries, are venesected incases of conjunctivitis, beginning of glaucoma, leucoma, night blindness and chronic headache. Their venesection is not free of risk, and the incision slow to heal." (Aspects of Treatment According to General Diseases, 21st section in Abu-Asab, Amri & Micozzi, 2013, Avicenna's Medicine).
