1. Complete Apothecary Formula: Gui Zhi Jia Xing Zi Tang + Gan Jiang, Wu Wei Zi & Fu Ling
To resolve an autumn Wind-Cold + AC-induced dry cough at the root—releasing the exterior chill, warming the Lung to steam fluids back up to the dry throat, and relaxing bronchial spasm without over-drying the body—the prescription merges Gui Zhi Jia Xing Zi Tang (桂枝加厚朴杏子湯 logic) with the Gan Jiang + Wu Wei Zi + Fu Ling triad:
| Herb Name (Pinyin / English) | Chinese Name | Weight (g) | Ratio | Classical Role & Thermodynamic Mechanism |
|---|---|---|---|---|
| Gui Zhi (Cinnamon Twig) | 桂枝 | 9 g | 3 | Releases Exterior & Warms Yang: Opens Taiyang pores locked by AC chill and drives Qi transformation (Hua Qi) so warm fluids rise to the throat. |
| Ku Xing Ren (Bitter Apricot Kernel, crushed) | 苦杏仁 (打碎) | 9 g | 3 | Descends Lung Qi & Moistens: Bitter-warm and oil-rich; stops the spasmodic cough reflex and moistens autumn Lung dryness without cooling the stomach. |
| Gan Jiang (Dried Ginger) | 乾薑 | 6 g | 2 | Warms the Lung & Middle Burner: Pairs with Zhi Gan Cao to warm cold-contracted lungs and vaporize fluids upward. |
| Wu Wei Zi (Schisandra Fruit, crushed) | 五味子 (打碎) | 6 g | 2 | Astringes Cough & Generates Fluids: Pairs 1:1 with Gan Jiang; locks down rebellious coughing while generating warm fluids (Sheng Jin 生津). |
| Bai Shao (White Peony Root) | 白芍 | 9 g | 3 | Relaxes Bronchial Spasm: Pairs with Gui Zhi to harmonize the exterior, and with Zhi Gan Cao (Shao Yao Gan Cao Tang chassis) to stop smooth-muscle airway spasms. |
| Fu Ling (Poria) | 茯苓 | 12 g | 4 | Supports Spleen & Moves Water: Prevents trapped fluids in the Lung and Stomach from congealing into lingering phlegm. |
| Zhi Gan Cao (Honey-Fried Licorice) | 炙甘草 | 6 g | 2 | Harmonizes & Soothes Throat: Buffers acrid warmth and calms local throat irritation. |
| Sheng Jiang (Fresh Ginger) | 生薑 (鮮) | 9 g (3–4 thick coins) | 3 | Assists Exterior Release: Works with Gui Zhi to push wind-cold out of superficial channels. |
| Da Zao (Torn Red Dates) | 大棗 (擘開) | 4 pcs (~12 g) | 4 | Replenishes Ying Fluids: Ensures warming and releasing the exterior never depletes body fluids in dry autumn weather. |
2. The Four Shanghan Lun Layers and Decoction Protocol
- The Gui Zhi Tang Chassis: Unlocks cold trapped in the skin and upper back from walking between warm streets and aggressive indoor AC.
- Gan Jiang + Wu Wei Zi: The "open-and-close" cough switch—scattering cold freezing fluid distribution while stopping airway tickles.
- Shao Yao Gan Cao Tang Pair: Directly relaxes the cramping, non-stop cough reflex in the trachea.
- Ku Xing Ren: Lubricates the dry respiratory tract with natural seed oils while directing rebellious Lung Qi downward.
Decoction & Administration Protocol
- Crush Seeds: Lightly smash Ku Xing Ren and Wu Wei Zi in a mortar before soaking.
- Soak: Soak all herbs in 800 ml of cold water for 30 minutes.
- Boil: Bring to a rolling boil, then simmer gently for 25–30 minutes down to 350–400 ml.
- Dose: Divide into 2 warm doses. Stay out of direct AC drafts until a light, warm micro-sweat appears on the skin, signaling the trapped cold has exited the Taiyang layer.
3. Empirical Validation: The Physics of Instant Relief
When this micro-dose formula hits a cold-locked system, physical recovery follows precise thermodynamic markers:
- No Upward Head Pressure: Unlike harsh diaphoretics that drive heat into the temples, the Gui Zhi and Bai Shao pairing disperses expansion harmoniously through the superficial channels and trunk.
- The Thermodynamic Switch: Gan Jiang provides upward vaporizing momentum while Xing Ren and Gui Zhi descend rebellious Qi, instantly terminating airway spasms without causing cardiovascular strain.
- The Clean Micro-Sweat (Wei Yang De Fu 衛陽得複): The gentle, non-exhausting sweat indicates that defensive Yang has successfully pushed the external cold out through the pores, restoring the Lung's natural descending and moistening functions.

2. 四層《傷寒論》機理與煎服規範
- 桂枝湯主體： 解開往返溫熱街道與冰冷空調所鎖在皮膚及上背部的寒邪。
- 乾薑 ＋ 五味子： 經典的「開闔」止咳開關——乾薑散開凍結津液分佈之寒，五味子止住咽喉狂暴癢感。
- 芍藥甘草湯對藥： 直接放鬆氣管中痙攣不休的咳嗽反射。
- 苦杏仁： 提供天然種子油脂潤澤乾燥呼吸道，並引導上逆肺氣下行。
煎煮與服藥規範
- 打碎種子： 浸泡前務必先將苦杏仁與五味子在缽中輕輕搗碎。
- 浸泡： 將所有藥材浸泡於 800 毫升冷水中 30 分鐘。
- 煎煮： 大火煮沸後，轉小火慢煎 25 至 30 分鐘，濃縮至大約 350–400 毫升藥液。
- 服法： 濾出並分為早晚兩次溫服。服藥後避免直接吹空調，直至皮膚微見溫潤汗出，即表示表寒已透出太陽層。
