Among the Jin-Yuan Dynasty physicians, Li Dongyuan (Li Gao) stands out for his singular clinical insight: most chronic illness in ordinary people originates from Spleen-Stomach deficiency, and restoring the Middle Jiao is the foundation of all treatment. His formula Yi Qi Cong Ming Tang (Supplement Qi and Brighten the Senses Decoction) applies this principle to a specific and practically significant clinical problem — ears and eyes that deteriorate not from local organ pathology, but from insufficient Spleen-generated Qi failing to rise to nourish the upper sensory orifices. Eight herbs that supplement, ascend, clear, and consolidate: the result is improved hearing, clearer vision, and a reduction in the dizziness and fatigue that accompany progressive sensory decline. Li Dongyuan called it one of his three major Qi-supplementing and Yang-raising formulas, alongside Bu Zhong Yi Qi Tang and Sheng Yang Yi Wei Tang.

I. Classical Source and Theoretical Basis

Yi Qi Cong Ming Tang is recorded in Li Dongyuan's Dong Yuan Shi Xiao Fang, Volume 5: "Yi Qi Cong Ming Tang treats irregular diet and physical overwork injuring the Spleen-Stomach, with resultant internal eye obstructions, tinnitus, or years of eye darkening and inability to see. This formula can enlarge the eyes; with long-term use there will be no internal or external eye obstructions, no tinnitus or deafness, and it additionally increases vitality, naturally supplements original Qi, lightens the body, strengthens health, and sharpens hearing and vision."

The theoretical foundation: the Nei Jing states "clear Yang exits through the upper orifices." The five organs all receive Qi from the Spleen-Stomach and transmit it to the nine orifices. When the Middle Jiao is fatigued and damaged, harmonious clear Qi can no longer ascend; the upper orifices — ears and eyes — lose their nourishment and become dim and dulled. The Yi Zong Jin Jian commentary: "Yi Qi Cong Ming Tang treats Qi-deficiency eye darkening and tinnitus, using Ren Shen and Huang Qi to supplement Qi, Sheng Ma and Ge Gen to raise Yang, Man Jing Zi to clear the head and brighten the eyes, Shao Yao to consolidate Yin, Huang Bai to descend Fire — together achieving Qi-supplementing, Yang-raising, ear-brightening and eye-clarifying."

The classical mnemonic: "Yi Qi Cong Ming Tang: Man Jing; Sheng, Ge, Shen, Qi, Huang Bai combined; also Shao Yao and Zhi Gan Cao; ear deafness and eye obstruction cleared by taking it." Referenced in Dong Yi Bao Jian and Mu Jing Da Cheng, the formula's clinical experience has been continuously enriched over centuries.

II. Eight-Herb Composition and Formula Analysis

Modern clinical reference doses: Huang Qi 15g · Ren Shen 6g (or Dang Shen 15g) · Zhi Gan Cao 6g · Sheng Ma 6g · Ge Gen 10g · Man Jing Zi 6g · Bai Shao 10g · Huang Bai 6g (wine-processed). The formula operates in three layers:

Layer 1: Supplement Qi, Strengthen Spleen — the foundational root treatment

• Huang Qi (Chief): sweet, slightly warm; enters Spleen, Lung. Supplements Qi and raises Yang, consolidates the surface and stops sweating. The largest-dosed herb in this formula — its Qi-supplementing action drives the entire upward Yang movement, giving clear Yang the power to ascend to the upper orifices. In clinical practice, dose often increases progressively: start at 15–20g, advance to 30–40g or even 60g for pronounced deficiency-driven visual and hearing decline.
• Ren Shen (or Dang Shen): sweet-slightly bitter, slightly warm; greatly supplements original Qi, nourishes Spleen and Lung, generates fluids and calms Spirit. Paired with Huang Qi, amplifies Qi-supplementing power and provides nutritive Qi-Blood substrate for the upper orifices. Use Dang Shen in routine cases; Hong Shen (red Ginseng) for severe deficiency.
• Zhi Gan Cao: sweet, neutral; supplements Qi, warms the Middle, harmonises all herbs. Assists Huang Qi and Ren Shen in Spleen strengthening; moderates Sheng Ma-Ge Gen's ascending tendency and Huang Bai's cold; prevents the formula from becoming over-warming or over-cooling.

Layer 2: Raise Yang, Clear the Upper Orifices — the targeted symptomatic action

• Sheng Ma: pungent-sweet, slightly cold; enters Lung, Spleen, Stomach, Large Intestine. Raises Yang and lifts depression, resolves the surface and clears Heat. Its ascending action drives the Spleen-Stomach's clear Yang upward toward the head and orifices, counteracting the failure of Yang to rise that is the pathomechanism of this formula's target pattern.
• Ge Gen: sweet-pungent, cool; enters Spleen, Stomach, Lung. Resolves muscles and clears Heat, generates fluids, raises Yang and stops diarrhoea. Paired with Sheng Ma, the two herbs coordinate to carry Spleen-generated clear Yang upward to the eyes and ears. Ge Gen additionally generates fluids to moisten dry eyes and mouth. Note for hypotension patients: Ge Gen has mild vasodilating and blood-pressure-lowering effects; if the patient has already low blood pressure (as in the documented clinical case), omit Ge Gen and use other Yang-raising combinations.
• Man Jing Zi (Vitex fruit): pungent-sweet, slightly cold; enters Liver, Stomach, Bladder. Disperses Wind-Heat, clears and brightens the head and eyes. The Shen Nong Ben Cao Jing records it for eye brightening; Ming Yi Bie Lu for "tearing eyes"; Zhen Zhu Nang for "dispersing darkness." Man Jing Zi acts directly on the head and orifices, dispersing the Wind-Heat that clouds clear Yang, and improving both hearing and vision. It is the formula's most targeted sensory-organ herb.

Layer 3: Consolidate Yin, Descend Deficiency-Fire — maintaining balance

• Bai Shao: sweet-bitter, slightly cold; enters Liver, Spleen. Consolidates Yin and nourishes Blood, soothes Liver and relieves cramping, calms and anchors Yang. Prevents the Yang-raising herbs from over-dispersing and depleting Yin fluids; nourishes the Blood substrate needed for eye and ear nourishment; moderates Sheng Ma-Ge Gen's ascending tendency.
• Huang Bai (wine-processed): bitter, cold; enters Kidney, Bladder, Large Intestine. Clears Heat and dries Damp, drains Fire and removes steaming. Targets the "Yin Fire" (deficiency-fire arising from Middle Jiao Qi deficiency) that disturbs the upper orifices, presenting as restlessness, bitter mouth, and eye redness. Wine-processing reduces its cold nature and prevents injury to the Spleen-Stomach. Huang Bai dose is modest (6g) and must not be increased in Cold-deficiency patients; in pronounced Spleen-Stomach Cold deficiency, it should be removed entirely.

Formula summary: Huang Qi, Ren Shen, and Zhi Gan Cao build the Spleen-Stomach Qi foundation; Sheng Ma, Ge Gen, and Man Jing Zi carry clear Yang upward and directly clear the orifices; Bai Shao and Huang Bai consolidate Yin and descend Deficiency-Fire to prevent Yang from rising excessively. Supplement without cloying; raise without being excessive; heat and cold balanced. A precise formula for Spleen-Stomach Qi deficiency with clear Yang failing to ascend.

III. Clinical Applications and Case Examples

1. Ear disorders: tinnitus and hearing loss
Pattern: low-pitched continuous tinnitus worsening with fatigue; progressive hearing loss; accompanied by fatigue, poor appetite, dizziness, pallor; pale tongue with thin white coating; thin weak pulse. This is the formula's primary classical indication. Pure Kidney supplementation alone is often insufficient for this pattern — the root is Spleen-Stomach Qi deficiency with clear Yang not ascending to nourish the ear.
Clinical case: 89-year-old woman, right ear long deaf, left ear tinnitus for years with progressive hearing decline — 10 days prior to consultation, left ear became near-totally deaf. Western diagnosis: senile neural deafness; recommendation: hearing aid. On examination: fatigued appearance, slow speech, otherwise clear-minded; sleep and appetite adequate; stool alternately loose and dry; frequent night urination; pale-red tongue with thin yellow slightly greasy coating; wiry thin weak pulse. Given Yi Qi Cong Ming Tang modified (Tai Zi Shen substituted for Dang Shen, added Su Geng, Xiang Fu, Chen Pi, Bai Ji Li). After 12 doses: left-ear hearing significantly improved. Three months later, relapse after emotional upset; re-treated with same formula, hearing restored again. Followed up six years with multiple relapses, all responded to this formula.
Modifications: prominent tinnitus and hearing loss → add Shi Chang Pu, Yuan Zhi, Ci Shi; Kidney deficiency signs → add Tu Si Zi, Gou Qi Zi, Du Zhong; Yin-Fire disturbance → add Huang Qin, Zhi Zi; sudden deafness → must seek specialist assessment and not self-treat.

2. Eye disorders: visual dimming, myopia, early cataract
Pattern: visual blurring, declining visual acuity, dry and easily fatigued eyes; with fatigue, poor appetite, dizziness; pale tongue, thin white coating; thin weak pulse.
Clinical case: 48-year-old man, bilateral eye aching and visual blurring, flashing lights in dark environments (worse in afternoon); ophthalmological diagnosis: pre-retinal detachment, vitreous opacity; previous treatments ineffective for 6 months. On examination: premature grey hair, haggard appearance, poor sleep and appetite; pale tongue, thin white coating; slow weak pulse. Given Yi Qi Cong Ming Tang. After 6 doses: eye aching and blurring slightly improved, less dark-environment flashing. After 12 doses: increased Huang Qi to 40g; condition stabilised, sleep and appetite improving. Continued progressively increasing Huang Qi; after 42 total doses, all visual discomfort resolved and complexion improved.
Modifications: dry eyes and visual blurring → add Gou Qi, Ju Hua, Jue Ming Zi; youth myopia → add Tai Zi Shen, Shan Yao, Mai Ya; early cataract → add Shi Hu, Yu Zhu, Sha Shen; ptosis (eyelid weakness) → markedly increase Huang Qi and Dang Shen.

3. Dizziness and headache (Qi-deficient type)
Pattern: mild continuous dizziness or headache worsened by fatigue or standing; with fatigue, pallor, poor appetite, low voice; pale tongue, thin weak pulse. Common in people with chronic overwork, sleep deprivation, and irregular diet — Western investigation typically unremarkable.
Clinical case: 37-year-old woman, intermittent dizziness 2+ years, sudden onset with inability to stand; brain MRI showed multiple ischaemic foci; cervical and neck vascular ultrasound normal; Vertèbres treatment ineffective with rest. Fatigue, dry mouth, bitter taste, difficulty falling asleep, easy waking, low blood pressure 82/50mmHg; red tongue tip, thin white coating; deep thin pulse. Given Yi Qi Cong Ming Tang modified — removed Ge Gen (vasodilating-antihypertensive action inappropriate for hypotension); added He Ye, Ze Xie, Dang Gui, Suan Zao Ren. After 7 doses: no dizziness episodes, fatigue reduced, dry mouth and bitter taste reduced, sleep improved; follow-up BP 100/60mmHg.
Modifications: dizziness → add Tian Ma, Gou Teng; headache → add Chuan Xiong, Bai Zhi, Fang Feng; low BP → remove Ge Gen, add Dang Shen, Bai Zhu; Blood Stasis → add Dan Shen, Tao Ren.

4. Age-related decline: memory loss and cerebrovascular disease
Pattern: memory decline, dizziness, limb numbness, slowed responses; with fatigue, poor appetite, lower back soreness; pale-dark tongue, thin white coating; thin weak or wiry slippery pulse.
Clinical case: 77-year-old man, dizziness 4 months, prominent on waking, visual blurring and fatigue, relieved by lying down; head CT: bilateral basal ganglia and corona radiata lacunar infarcts; TCD: basilar artery and right vertebral artery low-velocity flow; IV treatment showed minimal improvement. On examination: positional dizziness, occasional hand tremor, poor sleep, forgetfulness, limb numbness, frequent night urination (2–3×), dark tongue with thin white coating, wiry slippery pulse. Given Yi Qi Cong Ming Tang modified — added Chang Pu, Yuan Zhi, Yi Zhi Ren, Di Long, Dang Gui. After 14 doses: dizziness markedly reduced, night urination decreased, fatigue and limb numbness improved. 14 further doses: all symptoms resolved.
Modifications: memory decline → add Yuan Zhi, Yi Zhi Ren, Shi Chang Pu; cerebrovascular disease → add Dan Shen, Ge Gen, Di Long; limb numbness → add Ji Xue Teng, Sang Zhi; frequent night urination → add Yi Zhi Ren, Wu Yao.

IV. Usage, Dosage, and Safety

Preparation: water decoction once daily, 2 warm doses (1 hour after meals). Sheng Ma and Ge Gen benefit from extended decoction (10–15 min extra) to enhance Yang-raising. Huang Bai must be wine-processed. Li Dongyuan's original instruction: take near bedtime and again just before dawn; rest immediately after taking — sleep amplifies the Yang-ascending effect. Modern simplification: early morning and early evening, rest briefly after each dose.

Huang Qi dose escalation principle: begin at 15–20g; if response is evident, increase to 30–40g over 2–4 weeks. For severe eye or ear deficiency (as in the ptosis and vitreous opacity cases), progressive increases to 40–60g may be appropriate under practitioner supervision. This is one of Li Dongyuan's characteristic approaches — gradual Huang Qi escalation for stubborn deficiency conditions.

Patent forms: Yi Qi Cong Ming Tang granules and Yi Qi Cong Ming Tang decoction available; follow prescriber instructions or product insert. Not for self-prescription.

Contraindications: excess-type tinnitus-deafness (Liver Fire rising, Phlegm-turbidity obstructing orifices — loud tinnitus, irritability, yellow greasy tongue coating: this formula is contraindicated); pregnant women (Sheng Ma has ascending effect; use under supervision); allergy to any component; children (halve all doses; use under adult supervision).

Dietary cautions: avoid spicy, fried, oily, and cold-raw foods; no alcohol, strong coffee, or tea. The classical text prohibits "smoky, hot, and sour" foods. Favour light easily digestible foods (millet congee, yam, red dates, pumpkin) to support Spleen-Stomach Qi generation. Rest adequately; avoid overwork and late nights that exhaust the very Qi being restored.

Monitoring: if dry mouth or throat irritation develops, reduce Sheng Ma and Ge Gen and add Mai Dong and Xuan Shen to nourish Yin. If loose stool or abdominal discomfort occurs, remove Huang Bai and add Gan Jiang and Chao Bai Zhu to warm the Middle. Course for chronic conditions (senile hearing loss, early cataract, age-related memory decline): 3–4+ courses; do not stop abruptly when improvement begins. Youth myopia responds more quickly (1–2 courses) but requires concurrent proper visual hygiene.
