The Logic of Herbal Proportions: The 1:2.5 Ratio Architecture (方劑比例的邏輯：1:2.5 結構)

1. Beyond Guesswork: The Mathematics of Jing Fang

In classical Shanghan Lun prescribing, effectiveness relies entirely on strict proportional ratios (Bi Li 比例). Randomly throwing a handful of herbs into a pot ignores the precise topological balance required to shift an open thermodynamic system.

2. The Ying-Wei Ratio (Gui Zhi to Bai Shao)

Take the foundational Ying-Wei harmonization matrix: Gui Zhi (桂枝) is deployed at a ratio relative to Bai Shao (白芍) typically sitting around 1:1.5 to 1:2.5 (e.g., 9g of Gui Zhi to 15g of Bai Shao). Gui Zhi opens the defensive Wei layer and warms the channels, while a higher proportion of Bai Shao astringes the nutritive Ying layer and builds fluid reserves. If you flip or ignore these ratios, the thermodynamic vector collapses—either scattering the patient's energy too violently or trapping cold inside.

1. 超越盲目猜測：經方數學

在經典《傷寒論》處方中，療效完全取決於嚴格的比例結構。隨意將一把草藥丟進鍋中，會忽略引導開放熱力系統所需的精確拓撲平衡。

2. 營衛比例（桂枝與白芍）

以基礎的營衛調和矩陣為例：桂枝與白芍的相對比例通常維持在 1:1.5 至 1:2.5 之間（例如 9g 桂枝配 15g 白芍）。桂枝開啟防禦性的衛分並溫通經脈，而較高比例的白芍則收斂營分並建立津液儲備。若顛倒或忽略這些比例，熱力向量便會崩潰——要麼過於猛烈地發散患者能量，要麼將寒邪死鎖於內。
