What is the ratio of Gui Zhi to Shao Yao in Da Qing Long Tang?

• A. 2:1
• B. 1:1
• C. 1:2
• D. 1:3

Answer: (B)

The main idea here is the balance between releasing the exterior and preserving interior yin. In Da Qinglong Tang, Gui Zhi and Shao Yao are used in equal amounts. Gui Zhi helps push sweating to release wind-cold from the surface, while Shao Yao nourishes the yin and helps restrain excessive sweating and cramps, preventing injury to the yin while still allowing exterior release. Using them in a 1:1 ratio keeps these effects in harmony, so the exterior is released without over-drying or harming the interior. If the ratio shifted toward more Gui Zhi, the formula could over-release or warm the interior; if it shifted toward more Shao Yao, the exterior release might be insufficient. So the 1:1 balance is how this formula achieves its intended action.
