What are collateral points? ——Key nodes in the meridian theory of traditional Chinese medicine

Luo points are special acupoints that connect meridians and collaterals in the meridian theory of traditional Chinese medicine. They have the function of communicating the inside and outside and regulating qi and blood. This article will start from four aspects: the definition, function, clinical application and modern research of collateral points, focusing on analyzing their value in the treatment of integrated traditional Chinese and Western medicine. The content structure is as follows: first, an overview of the core concepts of Luo points, secondly, analysis of their physiological effects, then discussion of the clinical application of representative Luo points, and finally a summary of the modern medical significance of Luo points.

1. The physiological functions of collateral points and their relationship with meridians

Luo points are the locations where the fifteen collaterals branch out from the main meridian, such as the Liequ point on the Taiyin Lung Meridian of the Hand, Fenglong Point on the Stomach Meridian of Foot Yangming, etc. Traditional Chinese medicine believes that collateral points can regulate the connected meridians and collaterals in both directions, and are especially good at treating diseases of the external and internal meridians. For exampleWaiguan point(Hand Shaoyang Sanjiao Meridian Point) can not only relieve upper limb pain, but also improve Shaoyang Meridian symptoms such as tinnitus. Modern research shows that stimulating collateral points can improve local microcirculation through the neuro-humoral mechanism, which is consistent with its traditional effect of "unblocking collaterals and removing blood stasis".

2. Clinical application examples of classic collateral points

toGongsun point(Spleen Meridian Point of Foot Taiyin) for example, "Acupuncture A and B Meridian" records that it mainly treats "epigastric pain and diarrhea", and is commonly used in modern times for functional dyspepsia. Clinical data shows that acupuncture at Gongsun point combined with Neiguan point (the intersection point of eight meridians) is effective in treating gastric motility disorders up to 78% (see table below). Another exampleDazhong point(Foot Shaoyin Kidney Meridian Point) has shown the effect of regulating urinary protein in the auxiliary treatment of chronic nephritis, which reflects the characteristics of "one point regulates two meridians".

3. Modern research and equipment application of collateral points

With the deepening of research on meridians, some medical devices have developed products targeting meridians. Such as a certain brandElectronic acupuncture instrument(Manufacturer: XX Medical, product name: YY-type collateral point stimulator) simulates acupuncture acupuncture points through low-frequency electric pulses, and is used for auxiliary treatment of shoulder and neck pain. Studies have pointed out that this non-invasive stimulation can activate mast cells in the collateral acupoint area to release ATP, indirectly verifying the theory of "qi reaches the disease site" of traditional Chinese medicine. However, it should be noted that such devices must be used under the guidance of a physician and cannot replace regular treatment.

Summary: The inheritance and innovative value of Luo points

As the essence of the meridian theory of traditional Chinese medicine, acupuncture points not only carry the traditional wisdom that "the meridians pass through, the main treatment is affected", but also display scientific connotations such as neuromodulation and immune regulation in modern medicine. Future research can further explore the relationship between collateral points and fascia mechanical conduction, providing new ideas for the management of chronic diseases. When using collateral point therapy, it is recommended to choose a regular medical institution and provide treatment based on syndrome differentiation and individual constitution.
