Acupuncture Points: Channel Points, Five Shu Points, and Point Classifications
Overview of Points, Channels, and Point Types
Points reflect internal body conditions and can indicate internal disharmony beyond the skin area; they can be used to diagnose, guide self-care, and direct self-massage or treatment when needed.
Channels and points organize acupuncture knowledge:
There are primary meridians plus extra channels (the Du mai and Ren mai), totaling channels.
There are about fixed points commonly referenced (with some sources listing ; the discrepancy comes from counting or including certain points differently).
The largest group of points are on the channels themselves (channel points) located on the 14 channels and the extraordinary (non-channel) points.
Extraordinary points are fixed-location points not belonging to any of the 14 channels; they have their own names.
Osseo (osso/e) points are unfixed tender points found by palpation; they do not have a fixed channel location and may appear or disappear with condition changes.
Major point categories discussed:
Channel points (on the 14 channels): fixed locations, fixed names, used to move qi and connect channels.
Extraordinary points: fixed locations, not on any channel, with specific indications.
Osseous (osseous/osseous) points: unfixed, tender points found by palpation; can be acupuncture targets when appropriate.
Five Shu points (per channel): Jing Well, Ying Spring, Shu Stream, Jing River, He Sea; each channel has these five points in order from distal to proximal.
Source (Yuan) points: original or source points on the yin channels; important for foundation qi/transformation.
Luo Connecting points: linkage points between channels.
Eight Influential (Ba Xue) points: influential points for Zang, Fu, Qi, Blood, Sinews, Marrow, Bone, Vessel.
Crossing points: points where channels cross; noted but not deeply covered in this session.
Practical takeaways:
Five Shu points provide a compact, structured way to think about channel function and indications.
The channel system is bilateral; in practice, treatment is typically bilateral to balance qi and blood flow.
Point prescriptions are group-based (like a formula) rather than single-point treatments; they guide tonification vs reduction and qi movement direction.
Distal points (below elbows/knees) tend to be more surface-feeling and sensitive; proximal points (elbows, knees, torso) work more deeply toward organ function.
What a Channel Point Is: Fixed Location, Fixed Name, Fixed Role
Channel points are located along the 12 primary meridians plus the two extra channels (Du mai and Ren mai), giving a total of 14 channels.
Each channel point has a fixed location and a fixed name; however, in daily practice you primarily need to remember the numbers rather than the names for exams/tests.
The “Four Gates” concept: a fixed bilateral pair used together to move qi effectively. Often cited as LI4 and LR3 on both sides (two points on each limb, four gates total).
They are used to move qi systemically and are generally avoided during pregnancy because moving qi can risk miscarriage if not carefully managed.
The idea of channel points vs body indications: channel points can reflect internal conditions and guide self-treatment beyond localized pain or skin regions.
Extraordinary Points and Osseous Points
Extraordinary points (非经络点): not part of the 14 channels, but have fixed locations and names; they are learned and used as part of wider acupuncture strategies.
Osseous points (osseo points or tender/unfixed points): not fixed to any channel; discovered through palpation and may shift with body state. They are sometimes used in dry needling, chiropractic, or PT contexts, but should be chosen with care to avoid adverse reactions.
Practical examples in the lecture include points like xi ye (the eyes of the knee) and other regionally named points whose indications reflect location-based effects (e.g., sleep, knee pain, lower back pain).
Five Shu Points: Five Levels on Each Channel
The Five Shu points per channel are a foundational framework:
Jing Well (井穴): located distally near the tips of fingers or toes; often the most distal point on the channel.
Ying Spring (荧泉): located before the joints (metacarpophalangeal joints in the hands or the corresponding toe joints); qi starts to rise and become more active at this level.
Shu Stream (滎穴): located after Ying Spring, closer to the mid-sections of the channel; qi becomes stronger.
Jing River (经滅? actually Jing River): located around the elbow or knee joints; qi moves more quickly here and the channel qi becomes more substantial.
He Sea (合穴): located near the end of the channel pathway (close to the elbow or knee on the channel’s path); used to regulate qi transformation and treat systemic issues such as dampness, diarrhea, and other organ-level qi issues.
Location logic (as described in the lecture):
Jing Well: most distal; the source of qi in the channel; commonly used when qi needs to be awakened or redirected.
Ying Spring: just proximal to Ying Spring joints; qi becomes more abundant and moves toward the interior.
Shu Stream: just beyond the Ying Spring; qi movement is stronger and the point is often used to tonify or disburden qi in the channel.
Jing River: where qi flow accelerates; used to regulate qi movement and address organ-level qi issues.
He Sea: lower along the channel near the elbow/knee; used to treat qi transformation and to counterflow (diarrhea, dampness, heaviness).
Practical clinical shading:
The speaker emphasizes that Jing Well points can be used to access heat or fullness and sometimes awaken consciousness; He Sea points can treat dampness and qi transformation and are deeply connected to organ function).
The Five Shu points are deeply tied to the five elements; they provide a structured way to balance qi and influence organ function.
Five Shu Points, Source Points, Luo, and the Element Chart
Source (Yuan) points: the original qi source points on the yin channels; important for the root of qi and foundational qi movement.
Luo Connecting points: points that connect channels and help with qi and blood movement between channels.
The Eight Influential (Ba Xue) points: influential for different body systems (Zang, Fu, Qi, Blood, Sinews, Marrow, Bone, Vessel); often used to guide organ-system level effects.
Crossing points: cross-channel interactions; noted but not the primary focus in this session.
The Five Shu chart and the Five Elements: the Five Shu points align with the Five Elements; this alignment supports planful prescriptions using elemental relationships (generation/creation and control/overcontrol relationships).
The speaker notes a practical teaching chart that maps Five Shu points to the Five Elements and discusses how to use this chart to build point prescriptions (though the exact mappings may vary by tradition and instructor).
Important caveat raised: the sequence of elements (which element starts a Yang vs Yin channel) is traditional and not universally proven; the educator cites aging texts as the origin of some mappings and emphasizes memorization as part of early study.
Distal vs Proximal, Sensitivity, and Divergent/Channel Flow
Distal points (below the knees and elbows): more surface-level qi, more sensitivity when needling, more immediate sensation for patients.
Proximal points (on the torso, elbows, knees higher up the channel): qi moves deeper toward internal organs; less surface sensation and more connection to organ function.
Divergent channels and qi pathways:
The qi in the channels moves in a default direction, but there are also divergent pathways that branch and connect internal organs; this supports deep internal regulation.
The practitioner may follow channel pathways or qi-circulation order from Five Shu points when needling, depending on the clinical goal.
Bilateral treatment is recommended because channels are bilateral and qi moves through symmetrical pathways; in practice, strong emphasis on balancing both sides when possible.
Practical Approach to Point Prescriptions and Treatment Principles
Point prescriptions are typically group-based (like a formula) rather than single-point focus; this mirrors how herbal formulas are used to harmonize and balance.
Techniques: tonify (increase qi) vs reduce (decrease qi) and whether to move qi in or out; some cases require more aggressive needling, while others can be managed with milder stimulation.
The combination of points and techniques should align with the patient’s constitution and the disease state; not every case requires heavy needling or all techniques.
The points work together as a system; even if a single point has a particular indication, its effect is amplified when used with a group of points that share a common goal.
The course emphasizes building a solid map first (big-picture channel functions) before memorizing individual points; later lectures will delve into individual channels and specific points with repeated practice.
Examples and Clinical Reasoning Discussed
Jing Well points can be used to drain heat or deficiency heat (empty heat) and to influence yin/yang transformation; they can also wake the body up or ground it depending on the context.
Ying Spring and Shu Stream points have staged effects along the channel: early stages regulate qi, later stages aim at tonification and deeper qi movement.
Jing River points are frequently used to regulate qi movement along a channel—especially useful for cough, wheeze, and broader qi regulation across organs.
He Sea points are strongly associated with qi transformation and can help with dampness, heaviness, and organ-based qi issues (e.g., digestive problems, diarrhea).
Lower He Sea and HUSI (Lower/Upper) points: used for qi counterflow and diarrhea and to regulate qi movement in the lower extremities; the lecturer notes overlap and debates in naming and organ relationships (e.g., Stomach 36 vs. Stomach 37/39 relationships with the large/small intestine).
The relationship between qi flow and body function is described metaphorically with rivers and wells: the Jing Well is a “well” (source), Ying Spring is a shallow stream, Shu Stream deeper, Jing River a rising river, and He Sea like a sea—depicting the progressive deepening and accumulation of qi as it travels through the channel.
A practical example is given about skin- and knee-related points (extra points like xi ye, the “eyes of the knee”) and how these regional points can be used for quick indications (sleep, knee pain, etc.) without deep diagnostic work.
Quick Reference to Core Concepts (recap for exam prep)
Channel system basics:
channels ( primary meridians + extra channels: Du mai and Ren mai).
Channel points: fixed locations and fixed names; used to move qi along channels.
Extraordinary points: not on channels; fixed location; unique indications.
Osseous points: unfixed; tender points found by palpation; usage varies.
Five Shu points (per channel): Jing Well, Ying Spring, Shu Stream, Jing River, He Sea.
Distal to proximal order; each point has a role in qi movement along the channel and organ relations.
Other point categories useful for strategy:
Source (Yuan) points; Luo Connecting points; Eight Influential (Ba Xue) points; Crossing points.
Point strategy and philosophy:
Treat as a group (not only single points) for effective balance and organ function.
Distal points tend to be more surface-level; proximal points target deeper organ regulation.
Bidirectional effects: balance leads to natural return of qi; in acute cases, channel regulation may require directional manipulation (tonify or reduce) to restore proper flow.
Thematic cautions and context:
Pregnancy considerations when using certain qi-moving points (e.g., Four Gates).
Distinguish between fixed channel points and unfixed/osseous points to avoid unsafe practices.
The five-element mapping with Five Shu points provides a framework for building point prescriptions beyond simple one-point indications.
Notes on Language and Terminology Used in This Lecture
Five Shu points are referred to with English names and occasionally Chinese terms; the instructor emphasizes that memorizing the locations and functions, then understanding how to apply them in groups, is key for exam readiness.
The speaker notes some debates about channel numbering and element sequencing (e.g., why Yin channels start with Wood vs Metal in a chart), attributing some mappings to traditional texts like aging literature rather than modern empirical proof.
The lecture sets up a two-part learning path: (1) build a big-picture map of channel functions and point categories, (2) drill down into individual channels and specific indications in subsequent classes.
Examples of How This Maps to Practice (illustrative scenarios)
If a patient has hypertension with headaches: use Jing Well to drain excess heat and balance yin-yang; then, depending on the case, move to Ying Spring or Shu Stream points to modulate qi and reduce internal heat; finally, He Sea points may be used to address systemic dampness and organ qi transformation.
When treating a patient with chronic cough from lung qi deficiency: use Shu Stream points on the lung channels to tonify qi and strengthen qi movement; Jing River points to regulate qi flow; He Sea points to support organ function and address dampness or counterflow.
In cases of sleep disturbance affecting mental calm, utilizing appropriate extraordinary or regional points (e.g., xi ye for knee region dynamics) can support balancing qi in a broader sense, alongside Five Shu point prescriptions.
