Warm-Disease (Wen Bing) Formulas & Clinical Strategy – Comprehensive Class Notes

Formulas in the Wen Bing school are extremely particular about:
- WHICH part of a plant is used (e.g., entire plant vs. only the first sprouting tendril).
- WHERE the herb should act in the body (light herbs → upper-jiao pathology; heavier herbs → middle/lower-jiao).
- HOW it is processed: weight of each dose, degree of pulverising, order of addition, flame strength, and exact cooking time.
Rationale: subtle changes in preparation shift the trajectory of the herb (upper vs. middle vs. lower jiao) and its therapeutic temperature (aromatic/light vs. bitter/heavy).
Practical limitation: such precision is easier in Jiang-Su or other herb-rich regions than in many modern U.S. clinics.

Classical dosage form: coarse powder.
Classical cooking sequence:
1. Boil $\textit{Wei Gen}$ (葛根, Kudzu root) in water first.
2. Remove flame to medium; add the other powdered herbs together.
3. Stop heat the moment fragrance reaches the nose – prevents volatile aromatics from escaping and preserves upward-directing action.
4. Over-boiling drives the formula bitter, heavy, and down into the middle/lower jiao, missing its target.
Substitution note: If $\textit{Lu Gen}$ (蘆根) is unavailable, $\textit{Sheng Gan}$ (生甘?) can substitute; many scholars think Sheng Gan was the original ingredient.

Herb	Key Actions / Comments
$\textit{Jin Yin Hua}$ (金銀花) & $\textit{Lian Qiao}$ (連翹)	Clear wei-level heat, resolve toxicity
$\textit{Lu Gen}$ (蘆根)	Clear heat, generate fluids, guide formula upward
$\textit{Jie Geng}$ (桔梗), $\textit{Niu Bang Zi}$ (牛蒡子), $\textit{Bo He}$ (薄荷)	Trio that guides herbs to throat; treat toxic-heat sore throat; upward, dispersing
$\textit{Dan Dou Chi}$ (淡豆豉), $\textit{Jing Jie}$ (荊芥)	Mildly warm; open exterior & provide vent (not force) for heat to escape
$\textit{Gan Cao}$ (甘草)	Harmonise; relieve throat pain
Small internal “mini-formula”: $\textit{Jie Geng + Niu Bang Zi + Gan Cao}$ ← classic sore-throat combo.

$\textbf{Han Fa}$ (汗法) = Sweating Method: forcibly induce sweat (e.g.
$\textit{Ma Huang Tang}$ , $\textit{Da Qing Long Tang}$ ).
$\textbf{Tou Fa / Tou Fa Xie Biao}$ (透法瀉表) = Venting/Penetrating: simply open the pores so heat escapes of its own accord; no strong diaphoresis (e.g.
$\textit{Yin Qiao San}$ ).
English “vent” ≈ Chinese 透: penetrate/open, not “fan” or “force.”

Base dose (harmonising): $\text{Chai Hu}\approx 9\text{–}12\,\text{g}$ .
To turn it into a releasing formula: raise $\text{Chai Hu}\rightarrow 24\text{–}60\,\text{g}$ .
$(\text{Dose ↑} \Rightarrow \text{More exterior-releasing})$
Still not a “sweating method”; rather a Shao-Yang release.

Ma Huang, Gui Zhi, Zi Su Ye: rise, dry, and can fuel existing fire.
Strategy: maintain a slight warmth (Dan Dou Chi, Jing Jie) so pores open without escalating internal heat.
Modern workaround when $\textit{Ma Huang}$ is banned: use large-dose $\textit{Sheng Jiang}$ + $\textit{Gui Zhi}$ or even $\textit{Cong Bai}$ to improvise a mild sweat.

Considered the 2nd foundational Wei-Level formula (some texts list Gui Zhi Tang first, others skip).
Core ingredients discussed:
- $\textit{Sang Ye}$ (桑葉) — light, cool, disperse wind-heat from Lung.
- $\textit{Ju Hua}$ (菊花) — same channel pair; benefits eyes.
- $\textit{Xing Ren}$ (杏仁) — descend Lung qi, stop cough.
- $\textit{Bo He}$ , $\textit{Jie Geng}$ , $\textit{Gan Cao}$ mirror Yin Qiao’s guiding/harmonising ideas.
Clinical focus: spring-time cough, itchy eyes, mild wind-heat (not strong toxic-heat sore throat like Yin Qiao).

Actions:
- Clear summer-heat.
- Resolve toxicity.
- Promote urination → carries heat out via Bladder.
Cultural note: popular as a cooling household snack in East Asian summers.

Master the four-level map: Wei → Qi → Ying → Blood AND the Triple Burner heat model.
Memorise core symptom sets before tackling every individual formula.
Focus first on the two “spring” Wei-level formulas (Yin Qiao San & Sang Ju Yin).
Even if you practice acupuncture only, use these pathomechanisms to locate heat & choose dispersing, clearing, or tonifying strategies.

Shang Han Lun dominated internal medicine up to $\approx$ early-1700s.
Ye Tian Shi (葉天士, $\text{c. }1650!\text{–}1746$ ) founded the Wen Bing current; warm-disease thinking ruled 1700s–20th C.
Last 20–30 years: noticeable Shang Han revival (e.g., Prof. Huang Huang’s popularity; Shang Han formulas re-entering subtropical Taiwan clinics).

Classic herbal lists often exist in poem form; students in Taiwan create updated, rhyming — sometimes “saucy” — mnemonics.
Re-ordering ingredients into acronyms or “dirty limericks” aids retention.

Over-cooling a “hot pot” with “ice water” (all-cold herbs) can “ruin the pot” — metaphor for damaging the Spleen/Stomach.
Warm-disease therapy teaches balanced, strategic cooling: include small warmth to keep the qi dynamic and protect the middle.
Practitioners must weigh classical purity vs. modern practicality (herb availability, legality, patient location).
