01 — Palpation Beyond the Pulse
The Full Scope of 切診
While pulse-taking (脈診) is the centerpiece of 切診, it is not the whole of it. The broader palpation examination (按診 àn zhěn) extends to the abdomen, the chest, the skin, specific acupoints, and lymphatic regions. In Japanese Kampo tradition (漢方), abdominal diagnosis (腹診 fukushin) is actually given more weight than pulse-taking, and is practiced as a complete diagnostic system in itself.
This article covers the major non-pulse palpation findings: abdominal zone mapping, skin temperature differentials, edema assessment, and the diagnostic use of acupoint tenderness — a technique that bridges diagnosis and treatment selection simultaneously.
02 — Abdominal Palpation
The Abdomen as Diagnostic Map
In Chinese Medicine, the abdomen is divided into regions that correspond to organ systems. The quality of the abdomen on palpation — its tone, tenderness, temperature, presence of masses, resistance, and the patient's response to pressure — each carry specific diagnostic meaning.
Upper Abdomen
Epigastric Region
心下 xīn xià · "below the heart"
The area directly below the sternum. Fullness + tenderness here = Stomach Qi constraint, food stagnation, or Phlegm. Hard and resists pressure = excess obstruction. Soft with a sense of emptiness = Stomach deficiency. In classical six-stage disease, "fullness below the heart" is a key pattern marker.
Right Flank
Liver / Gallbladder Zone
右脅 yòu xié
Tenderness or resistance under the right ribcage = Liver Qi stagnation or Liver Blood stasis. A palpable enlargement = Liver Blood stasis, Phlegm accumulation, or Liver Fire causing engorgement. This area is assessed for both tenderness and structural change.
Left Flank
Spleen Zone
左脅 zuǒ xié
Left hypochondriac tenderness or structural finding. Spleen enlargement in TCM framework correlates with Spleen Qi stagnation and Blood stasis accumulation. In Japanese Kampo, left flank resistance (左脅下抵抗) is one of the most frequently used abdominal signs.
Umbilical
Navel & Peri-umbilical
臍周 qí zhōu
The navel region reflects Spleen and Kidney Qi. Pulsation that is palpable and strong (腹部動悸 abdominal pulsations) = excess Qi churning — often Kidney Qi not anchored, or Chong Mai disturbance. Peri-umbilical coldness = Kidney Yang or Spleen Yang deficiency.
Lower Abdomen
Lower Jiao
小腹 xiǎo fù
Below the navel: Kidney, Bladder, Uterus, Lower Jiao. Hard, fixed resistance = Blood stasis (classic in gynecological Blood stasis). Cold to the touch + loose texture = Kidney Yang deficiency, Lower Jiao Cold. Tenderness with deep pressure = Bladder Damp-Heat or Uterus pattern.
Whole Abdomen
Tone & Resistance
腹力 fù lì
In Kampo, 腹力 (abdominal force/tone) is graded from 1–5. A very lax, soft abdomen = profound Qi and Blood deficiency. A very tight, rigid abdomen = excess pattern or significant tension (Liver Qi constraint, excess Yang). Normal = responsive, neither completely hard nor completely soft.
03 — Skin Palpation
Reading the Skin's Surface
The skin's temperature, moisture, and texture yield diagnostic information about the Wei Qi (Defensive Qi), fluid metabolism, and the thermal nature of the underlying pattern. The practitioner palpates the forehead, extremities, chest, and back systematically, noting differentials between regions.
Temperature
Hot Skin
Hot to the touch = Heat pattern. Forehead hot + body not = exterior pathogen localized. Entire body hot = interior Heat or high fever. Skin hot at night but cooler in the day = Yin deficiency Empty Heat rising to the surface at night.
Temperature
Cold Skin / Extremities
Cold hands and feet = Yang deficiency or Cold obstruction. Cold only in hands and feet but warm trunk = Qi stagnation preventing Yang from reaching the extremities (四逆). All-over cold skin = Yang collapse — serious sign requiring urgent assessment.
Moisture
Dry / Scaly Skin
Dry, rough, or scaly skin = Blood deficiency or Yin deficiency — the Blood cannot moisten and nourish the skin surface. Chronic dry skin despite adequate fluid intake = Blood is insufficient rather than fluid intake being the issue. Classic in elderly, post-illness, and chronic stress states.
Moisture
Damp / Sweaty Skin
Persistently moist or damp skin in areas other than expected = Damp accumulation or Wei Qi failure. Clammy skin with cold hands = Yang deficiency with Damp. Oily or slightly sticky skin around the scalp and face = Damp-Heat, often from Stomach or Liver.
Texture
Edema — Pitting
Pressing the skin with a finger leaves a pit that slowly refills = Damp accumulation. Pitting edema in the ankles and lower legs = Spleen or Kidney deficiency failing to metabolize fluids. The Spleen fails to transform; the Kidney fails to distribute water. Both produce pitting edema but with different systemic signs.
Texture
Edema — Non-Pitting
Swelling that doesn't pit on pressure = Phlegm accumulation or Blood stasis. The tissue is not fluid-filled but Phlegm-obstructed. In TCM, chronic thyroid enlargement (Goiter — 癭瘤) is classified as Phlegm-stasis accumulation. Hard, non-pitting, fixed swelling = Blood stasis with Phlegm.
04 — Acupoint Tenderness
Diagnostic Acupoint Palpation
Certain acupoints become tender or reactive when the corresponding organ or channel is pathological. This technique — pressing specific acupoints and noting the patient's response — simultaneously diagnoses and confirms the pattern, and guides point selection for treatment. Practitioners call this "finding the Ashi" (阿是 āshì — "ah yes!" points of tenderness), but structured acupoint palpation goes beyond general tenderness.
Mu-Front Points 募穴
Front-Alarm Points
Each Zang-Fu organ has a Mu-Front point on the chest or abdomen that becomes tender in excess or acute organ pathology. Tenderness at CV12 (Zhongwan) = Stomach involvement. LV14 (Qimen) = Liver. LU1 (Zhongfu) = Lung. Palpation of these points with fingertip pressure of 1–2 kg reveals which organ is in excess.
Shu-Back Points 俞穴
Back-Transport Points
The Bladder channel Shu (俞) points along the paravertebral line reflect organ Qi in both excess and deficiency. Tenderness at BL23 (Shenshu) = Kidney deficiency. BL18 (Ganshu) = Liver involvement. These points are palpated on the back along the first Bladder channel line, 1.5 cun lateral to the spine. Deficiency patterns present as soreness on sustained pressure; excess as sharp pain on contact.
Xi-Cleft Points 郄穴
Accumulation Points
Xi-Cleft points become acutely tender in sudden, intense pathology of their channel — especially pain conditions and acute excess. PC4 (Ximen) for Heart pain. LU6 (Kongzui) for acute Lung conditions or hemoptysis. Intense pressure tenderness at a Xi-Cleft point suggests acute channel obstruction or emergency-level organ involvement.
Key Diagnostic Points
Three Important Sites
ST36 (Zusanli): Tenderness or tightness here = Stomach-Spleen Qi deficiency or accumulation. SP6 (Sanyinjiao): Tenderness = Liver, Spleen, or Kidney involvement at the lower jiao. KD3 (Taixi): Soreness on deep pressure = Kidney deficiency (Yin or Yang). These three are among the most palpated diagnostic acupoints in clinical practice.
Combining Palpation with Needling
In clinical practice, acupoint tenderness directly guides point selection. A point that the patient identifies as "sore, but not in a bad way" on pressure — what TCM calls 酸脹感 (the characteristic achy, distending sensation) — confirms that the channel Qi is accessible there. This is the starting point for effective needle placement.
05 — Lymphatic and Channel Zones
Lymph Nodes, Swellings, and Channel Palpation
Lymph node tenderness and swelling are interpreted in TCM through the channel system. Cervical lymph nodes that are tender = Wind-Heat or Shaoyang (少陽) stage — the Gallbladder and Triple Burner channels run through the neck and ear regions. Axillary swelling = Liver or Gallbladder channel Heat rising through the arm channels. Inguinal nodes = Lower Jiao Damp-Heat.
Channel palpation — running a finger along the channel line to find tightness, ropiness, or tender spots — identifies where Qi and Blood are accumulating or stagnating before needling. In particularly experienced practice, the entire back is palpated along the Bladder channel for areas of tension or deficiency before any diagnosis is confirmed.
The Four Examinations Together
This article completes the Ten-part TCM Diagnosis Series. The four examinations — 望 Inspection, 聞 Listening, 問 Inquiry, 切 Palpation — are not sequential steps but overlapping lenses. Used together, they triangulate from four different angles toward a single pattern diagnosis. No one examination is sufficient. The pattern that emerges from all four — consistently — is where the diagnosis lives.
