    Notes:
    Ling Shu Ch. 6 suggests piercing the Luo points if a disease is in the Yang of the Yin realm (e.g. the Fu organs) implying this point for disorders of the Bladder.

    Ling Shu Ch. 10, On Channels, describes the diseases relating to the Luo emanating from this point as:
    Repletion: Nose is blocked, head and back ache
    Depletion: Nasal flow and nosebleed
    (Unschuld, 2016).

    Ling Shu Ch. 19, On the Four Seasonal Qi, advises using the channels and Luo vessels for diseases which occur in spring. They are pierced deeply if severe and more shallow if mild. For the other seasons:
    - in summer choose the Yang channels and Luo located in the partings between the skin and flesh
    - in autumn choose the Shu-Stream points unless the disease in the Fu organs, then use the He-Sea points
    - in winter choose Jing-Well and Ying-Spring opening and retain the needle.

    Ling Shu Ch. 21, On Cold and Heat Diseases, repeats the advice to use Luo in spring but and adds that they can also treat diseases of the skin. For the other seasons it differs slightly from Ch. 19:
    - in summer choose the partings in skin structures which also treat the muscle and flesh
    - in autumn Taiyuan Lu-9 is chosen and can treat the sinews and vessels (this may also apply to other Shu-Stream points for this purpose, text is unclear)
    - in winter one chooses the main channel points which also treat the bones and marrow.

    Later it suggests using these Luo vessels when the lower abdomen is swollen and there is difficulty urinating along with Luo of the Jueyin (Ligou Liv-5) if they are knotted with blood. If it reaches the stomach then Zusanli St-36 is added.

    Ling Shu Ch. 21, on Cold and Heat Disease, advises pricking the Luo collaterals of the Taiyang emanating from here in cases of alternating cold and heat with supplementation of an additional channel based on the specific presentation:
    - if the hot and cold sensations are in the skin, the nose is dried up and the patient unable to sweat, supplement the Hand Taiyin Lung channel
    - if the hot and cold sensations are in the muscles, the lips are dry and they are unable to sweat, supplement the Foot Taiyin Spleen channel
    - if the hot and cold sensations are in the bones and they sweat ceaselessly then this point is not used but the Luo of the Foot Shaoyin, Dazhong Kid-4, is chosen instead.

    Ling Shu Ch. 22, On Mania and Madness, advises to bleed this channel in instances of insanity. The original just states the division (eg. bleed foot Taiyang) implying the main channel by omission but since it recommends bleeding the data is being entered under the Luo points unless a specific point is mentioned:
    - If a manic patient's back is stiff and bent backwards like a bow with pain in the spine (opisthotonos?) then the hand and foot Taiyang (Wu and Wu, 2010), and the foot Yangming and Taiyin (Unshculd, 2016) are bled.
    - If a major delight causes a person to see demon-spirits and laugh inside but be unable to express it then blood is removed from the foot Taiyin, Taiyang and Yangming, and then from the hand Taiyin and Yangming.
