What does 'Ghost point' refer to in this context?

In the context of acupuncture, a 'Ghost point' refers to specific acupuncture points that are traditionally associated with psychological and emotional disturbances, often linked to spiritual issues or conditions like mania, depression, or epilepsy. The point LI-7, known as “Wenliu,” is recognized as one of these Ghost points. It is located on the large intestine meridian and is utilized to address issues related to the mind and spirit.

The classification of Ghost points stems from historical Chinese medicine practices, which often identify certain points with significant effects on mental health. Practitioners may use LI-7 in treatments for its spiritually grounding effects and its potential to address emotional instability, highlighting its role beyond just physical ailments.

Other points listed, like LI-11, LI-18, and LI-20, are generally used for different therapeutic purposes and do not hold the same associations with the treatment of spiritual or psychological conditions. Thus, their classification as Ghost points is not supported, as they focus more on physical issues connected to their anatomical locations or functions within the flow of energy (Qi) along the meridians.
