    Ling Shu Ch. 10, On Channels, describes the diseases relating to the Luo emanating from this point as:
    Repletion: Closure with protuberance-illness (prostate hypertrophy)
    Depletion: Lower back aches
    (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.

    The same chapter also says that if it is the bones which feel cold and heat sensations and the patient sweats ceaselessly it should be treated with the Foot Shaoyin Luo vessels on the inner thigh. If the teeth have dried up or the bones have ceasing Qi then no cure is possible.

    Ling Shu Ch. 22, On Mania and Madness, advises that if the breath is shortened and brief and movement makes the Qi appear restrained then the foot Shaoyin channel is to be supplemented and the Luo are to be drained.

    Ling Shu Ch. 26, On Miscellaneous Diseases, advises piercing the foot Shaoyin blood vessels in the hollow of the knee for lower back pain with heat in the centre and panting (probably Weizhong Bl-40 rather than here but this is the origin of the foot Shaoyin Luo).
