Ashi points
Ashi points are spontaneous tender or reactive points on the body that appear in response to illness or injury. Unlike fixed acupuncture points, they have no predetermined location and are identified through palpation based on the patient's pain or comfort response.

Overview
Ashi points represent one of the most intuitive and practical concepts in acupuncture. Unlike the 365 classical points that have fixed locations along the meridians, Ashi points are discovered fresh each time—they appear wherever the body signals distress through tenderness or discomfort when pressed.
The name "Ashi" comes from the patient's exclamation when the practitioner finds the sensitive spot: "Ah, yes!" (阿是) or "That's the spot!" This elegant simplicity reflects the point's nature—it's wherever the problem manifests. When Qi (the body's vital energy) and blood become blocked or stagnant, the affected area becomes tender to touch. These reactive points serve as both diagnostic markers revealing where energy flow is disrupted and therapeutic targets for treatment.
In modern terms, Ashi points share remarkable similarities with what Western medicine calls "myofascial trigger points"—those knotty, tender spots in muscles that refer pain to other areas. Research has shown that approximately 93% of common trigger points correspond to established acupuncture point locations, suggesting both traditions independently discovered the same effective treatment sites on the body.
Historical Context
The concept of treating tender points stretches back to the earliest Chinese medical texts. The Ling Shu (Spiritual Pivot), part of the ancient Huangdi Neijing (Yellow Emperor's Classic), contains the phrase "yi tong wei shu" (以痛为腧)—"take the pain as the point"—establishing the principle of needling where it hurts. However, the formal term "Ashi point" first appeared during the Tang Dynasty (618-907 CE).
The legendary physician Sun Simiao (孙思邈), known as the "King of Medicine," coined the term in his masterwork Qianjin Yaofang (Prescriptions Worth a Thousand Gold). According to popular legend, while treating a patient with severe leg pain that didn't respond to standard point prescriptions, Sun Simiao methodically pressed along the leg until the patient suddenly cried out "Ah, yes! That's the spot!" (阿是). He needled this unmarked location and the pain subsided. This approach—finding and treating wherever the body reveals its distress—became known as the "Ashi method."
Sun Simiao's contribution elevated what had been folk practice into formal medical theory. He recognized that beyond the established meridian points, the body creates temporary reactive points during illness that deserve equal attention in treatment. This insight expanded acupuncture from a purely systematic approach to one that honors the body's individual expression of disease.
No Fixed Location
无定处Unlike the 365 classical acupuncture points that occupy specific anatomical positions, Ashi points have no predetermined location. They emerge dynamically wherever the body manifests dysfunction. This means an Ashi point could appear literally anywhere—on the back, leg, hand, or even locations far from the obvious site of complaint. The point exists only where and when the body signals distress.
Pain or Comfort Response
快或痛Identifying Ashi points requires skilled palpation and patient feedback. Contrary to popular belief, Ashi points aren't always painful. Sun Simiao's original text specifies finding places that are either tender (痛) OR bring a feeling of relief/comfort (快然) when pressed. In chronic or deficiency conditions, pressing the right spot often feels good rather than painful. The key is finding where the body responds meaningfully to touch.
Reflects Qi and Blood Stagnation
气血阻滞From a TCM perspective, Ashi points appear when Qi (vital energy) and blood cannot flow freely through the channels. Think of it like a river with a dam—pressure builds up at the blockage site. These tender points mark exactly where the flow is obstructed, making them both diagnostic indicators of where the problem lies and ideal treatment targets to restore circulation.
Dynamic and Temporary
临时性Ashi points are not permanent features of the body like classical acupuncture points. They arise with illness or injury and disappear once the condition resolves. A patient recovering from a neck strain might have several Ashi points in their trapezius muscle during the acute phase that completely vanish once healed. This dynamic nature reflects the body's changing state of health.
Practitioner Palpation Skills
揣穴Finding Ashi points requires the practitioner to develop sensitive hands. Beyond asking "does this hurt?", experienced practitioners feel for subtle tissue changes: nodules, taut bands, areas of unusual hardness or softness, temperature differences, or regions where the tissue feels "stuck." These palpable findings often correspond to where patients report tenderness and where treatment proves most effective.
Practical Application
Finding Ashi Points: Begin by asking the patient where they feel discomfort, then systematically palpate the area using thumb or fingertip pressure. Move slowly, pressing into the muscle tissue to different depths. Note places where the patient reports tenderness, shooting sensations, or relief. Also pay attention to what you feel under your fingers—look for taut bands, nodules, areas of unusual texture, or spots that feel different from surrounding tissue.
Treatment Methods: Once identified, Ashi points respond well to multiple treatment approaches. Acupuncture needling is most common, often using slightly thicker needles and deeper insertion than for classical points. Strong stimulation techniques may be appropriate for excess-type pain conditions, while gentler methods suit deficiency patterns. Moxibustion (warming with burning mugwort) works excellently for cold-pattern Ashi points. Cupping, gua sha, and acupressure massage are also effective.
Integrating with Classical Points: Skilled practitioners combine Ashi points with classical meridian points for comprehensive treatment. For example, treating lower back pain might include local Ashi points in the paraspinal muscles plus classical points like BL-40 (Weizhong) for its distal effect on the back, and BL-23 (Shenshu) to address underlying Kidney involvement. This integration of reactive local points with systematically selected distal points often produces superior results to either approach alone.
Clinical Relevance
Primary Applications: Ashi points excel in treating musculoskeletal pain—back pain, neck tension, sports injuries, repetitive strain conditions, and arthritis. The principle of treating local tender points makes intuitive sense for these conditions and delivers rapid results. Research comparing Ashi point treatment to standardized point protocols often shows equivalent or superior outcomes for pain conditions.
Beyond Pain: While most associated with pain treatment, Ashi points extend to internal medicine. Organ dysfunction often manifests as tender areas on the body surface, particularly at back-shu points (along the spine) and front-mu points (on the torso). A patient with digestive issues might show tenderness at CV-12 (Zhongwan) or BL-21 (Weishu) even without conscious stomach pain. These reactive points indicate involvement of the related organ and guide both diagnosis and treatment.
Modern Correlations: The Western concept of myofascial trigger points—hyperirritable nodules in muscle that refer pain elsewhere—maps remarkably onto Ashi point theory. Research demonstrates over 90% overlap between mapped trigger points and acupuncture points. This convergence validates the Ashi approach and enables integration of Eastern and Western soft-tissue treatment methods. Dry needling, a modern Western technique that targets trigger points, essentially applies Ashi principles using acupuncture needles.
Common Misconceptions
"Ashi points are always painful": The original classical description specifies finding points that bring either pain OR comfort (快或痛) when pressed. Many Ashi points, particularly in chronic or deficiency conditions, feel good to press—patients describe relief or a pleasant sensation. Focusing only on pain misses these equally important reactive points.
"Any painful spot is an Ashi point": True Ashi points have therapeutic significance—treating them produces improvement. Not every tender area qualifies. Skilled practitioners distinguish meaningful reactive points (which often have palpable tissue changes) from general soreness. The patient exclaiming "that's the spot!" with recognition is different from wincing at any firm pressure.
"Ashi points replace classical point theory": Some practitioners over-rely on Ashi points while neglecting meridian theory and systematic point selection. The most effective treatments combine both approaches—using local Ashi points where the body reveals distress while adding classical points selected based on pattern differentiation and meridian relationships. Ashi work supplements rather than replaces traditional protocols.
"Ashi points are the same as trigger points": While significant overlap exists, the concepts aren't identical. Trigger points in Western medicine specifically refer to myofascial nodules with defined characteristics (taut bands, referred pain patterns, local twitch response). Ashi points have a broader definition encompassing any reactive point, including those related to organ dysfunction that don't fit the trigger point model.
Organizing Principle
Ashi points are unified not by anatomical location or meridian association, but by a simple diagnostic principle: they are reactive points that emerge during illness and respond meaningfully to treatment. The "Ashi method" (阿是之法) involves systematically palpating the body—especially areas related to the complaint—to discover where tenderness or comfort response reveals blocked energy flow.
Clinically, these points serve dual purposes. First, they help diagnose where the problem actually resides, which may be different from where the patient experiences symptoms. Second, they provide highly effective treatment targets because you're needling or applying moxibustion exactly where the body shows disturbance. This "treating where it hurts" approach makes Ashi points particularly valuable for musculoskeletal pain, but they also appear with internal organ dysfunction—often along the related meridian pathway or at back-shu and front-mu points.
Unlike systematic protocols that prescribe fixed point combinations, Ashi point treatment is inherently personalized. Each patient's points are discovered anew during examination, ensuring treatment addresses their unique pattern of dysfunction rather than a theoretical ideal.

Moxibustion Guidelines (灸例)有阿是之法，言人有病痛，即令捏其上，若里当其处，不问孔穴，即得便快或痛处，即云阿是，灸刺皆验，故曰阿是穴也。
There is the Ashi method: when a person has pain, have them press upon it. If the spot is indeed right at that place, regardless of whether it is a defined point, and pressing brings comfort or reveals pain, they say 'Ah yes!' Moxibustion and needling at such spots prove effective, hence they are called Ashi points.
