    Avicenna describes venesection along the accessory cephalic vein that runs approximately along the course of the arm Yangming Large Intestine channel in his treatise On Venesection:

    "The cephalic vein drains more blood from the neck and above, and little from below the neck, but it does not exceed the epigastrium, and it does not significantly cleanse the lower parts... The accessory cephalic vein is similar to the cephalic." (Aspects of Treatment According to General Diseases, 21st section in Abu-Asab, Amri & Micozzi, 2013, Avicenna's Medicine).

    The median cubital or basilic veins are used for the lower body.
