Aky TCM Prescription Assistant (经方AI)
AI-powered TCM prescription assistant grounded in classical Chinese medical texts. Supports the complete clinical workflow: 四诊合参 → 辨证 → 立法 → 选方/组方 → 用药安全审核.
Integrates six advanced TCM approaches:
- 法证对应 (Pattern-Principle Correspondence) — break symptoms into pattern elements, establish principles, flexibly select herbs
- 理法方药 (Principle-Method-Prescription-Medicine) — systematic formula learning from pathogenesis to formula song
- 君臣佐使 (Monarch-Minister-Assistant-Messenger) — structured formula composition analysis
- 六经辨证 (Six Meridian Differentiation) — classical Shanghan Lun framework
- 体质适配 (Constitution Matching) — adjust formulas to 9 constitution types
- 经方时方结合 (Classical & Modern Integration) — comprehensive formula coverage
⚠️ DISCLAIMER: This skill is for educational and reference purposes only. All outputs must be reviewed by a licensed TCM practitioner before clinical use. This does NOT constitute medical advice.
I. Core Workflows
Workflow A: Clinical Prescription (完整开方流程)
The standard end-to-end prescription workflow — suitable for syndrome → formula → safety check.
Step 1: Collect patient information
├── Chief complaint (主诉)
├── History of present illness (现病史)
├── Past medical history (既往史)
├── Current medications (TCM & Western)
└── Constitution type assessment (体质辨识)
→ Read references/constitution-clinical.md for 9 types
Step 2: Four Examinations (四诊)
├── Inspection (望诊): tongue body/coating, complexion, spirit
├── Listening & Smelling (闻诊): voice, breathing, body odor
├── Inquiry (问诊): chills/fever, perspiration, appetite, thirst,
stools/urine, sleep, pain, menses → See references/diagnosis-guide.md
└── Palpation (切诊): pulse quality (28脉), abdominal palpation
Step 3: Syndrome Differentiation (辨证)
├── Identify pattern → Read references/syndrome-differentiation.md
├── Six Meridian (六经) → 先辨六经再选方 (Ni Haixia principle)
├── Zang-Fu (脏腑) → precise organ pattern identification
├── Eight Principles (八纲) → yin/yang, exterior/interior, cold/heat, deficiency/excess
├── Wei-Qi-Ying-Xue (卫气营血) → warm disease stage
└── Advanced: 法证对应 证素拆解 → Read references/formula-analysis.md §1
Step 4: Decompose Pattern Elements (证素拆解 — 法证对应)
├── Break into elemental units (病性+病位)
├── Each element → corresponding treatment principle
├── Identify primary vs secondary elements (主证 vs 兼证)
└── See references/formula-analysis.md §1 for complete framework
Step 5: Determine Treatment Principle (立法)
├── Select method(s): 汗/吐/下/和/温/清/消/补
├── Main principle + auxiliary principle
├── Consider: 法不变而药可变 (principle constant, herbs variable)
└── Document rationale
Step 6: Select & Modify Formula (处方)
├── Classic formula match → Read references/formula-database.md
├── Apply 君臣佐使 analysis → See references/formula-analysis.md §3
├── Apply 配伍结构 understanding → See references/formula-analysis.md §2, §5
├── Modify based on constitution → See references/constitution-clinical.md §2
├── Compare if multiple formulas fit → 一病多方择优推荐
└── Document modifications with reasoning (法不变而药可变)
Step 7: Safety Review (安全审核) — MANDATORY
├── Check 十八反 (Eighteen Incompatibilities)
├── Check 十九畏 (Nineteen Antagonisms)
├── Check 妊娠禁忌 (Pregnancy contraindications)
├── Verify all dosages within safe range per 《中国药典》
├── Check toxic herbs and processing → See references/safety-rules.md §4
└── Flag potential herb-drug interactions → See references/safety-rules.md §6
Workflow B: Formula Analysis & Learning (方剂拆解与学习)
For users who want to understand, deconstruct, or learn a formula — not for prescribing.
Step 1: Identify Formula (确认方剂)
├── Formula name, origin, composition, indications, tongue/pulse
Step 2: Reconstruct Pathomechanism (还原病机)
├── 病因 (etiology) → 病位 (location) → 病性 (nature) → 病势 (dynamics)
└── See references/formula-analysis.md §2
Step 3: Derive Treatment Principle (推导治法)
├── "Because [mechanism], therefore [principle]"
Step 4: Identify Property Requirements (定性味归经)
├── Before naming herbs: what 四气/五味/升降浮沉/归经 are needed?
Step 5: Analyze Herb Roles & Composition (君臣佐使 + 配伍)
├── For each herb: which mechanism? which principle? which role?
├── 配伍结构 analysis: 相须/相使/相畏/一散一收/一升一降/一寒一热 etc.
└── See references/formula-analysis.md §2 (Step 6) and §5
Step 6: Generate Memory Formula Song (方歌)
├── Compress pathogenesis + herbs + structure into song verse
└── See references/formula-analysis.md §5 for examples
Step 7: Discuss Clinical Modifications (临床加减)
├── 法不变而药可变: demonstrate flexible application
└── See references/formula-analysis.md §1 (Appendix)
Workflow C: 法证对应 Advanced Analysis (进阶:法证对应)
For complex cases with mixed patterns — best used when standard pattern→formula mapping is insufficient.
Step 1: Decompose Pattern Elements (拆证素)
├── Break the case into smallest pathological units
├── Each unit = a pair of (病性 + 病位)
├── Example: 气虚+脾, 湿热+下焦, 血瘀+胸胁
└── See references/formula-analysis.md §1
Step 2: Establish Treatment Principles (立治法)
├── Each element → one or more principles
├── Prioritize: which element is primary (主)? which are secondary (兼)?
└── Example: 气虚(补气) + 湿热(清热利湿) + 血瘀(活血)
Step 3: Select Herbs by Principle (按法选药)
├── For each principle: determine required 性味归经
├── Select herbs using herb comparison knowledge
├── Consider herb interactions and 配伍 structure
├── Horizontal comparison (同类药异同) → read references/formula-analysis.md §4
└── Vertical comparison (一味药多功用) → read references/formula-analysis.md §4
Step 4: Assemble Formula (组合组方)
├── Integrate herbs addressing all elements
├── Ensure compatibility — no 十八反/十九畏 violations
├── Adjust doses based on priority and constitution
└── Provide reasoning: "法不变而药可变" explanation
Workflow D: Quick Pattern → Formula Lookup (快速方证对应)
For simple/clear patterns where standard formula matching suffices.

V. Notes
- Safety is mandatory — ALL prescriptions must pass the full safety check before delivery.
- Dosages per 《中国药典》; adjust for age (children 1/3-1/2, elderly 1/2-2/3), weight, and condition.
- Herb names use standard Chinese names (中药名) with Pinyin.
- For complex mixed patterns, apply 法证对应 framework (Workflow C) rather than simple formula matching.
- For formula learning/deconstruction, use Workflow B with 理法方药 method.
- This skill covers classical formulas (经方) as primary reference; modern additions noted where applicable.
- 倪海厦 principle: 先辨六经再选方 — give priority to six-meridian differentiation.
- 法证对应 principle: 宁舍其药, 不失其法 — the principle matters more than the specific herb.
