Yi Guan Jian — Linking Decoction
On this page
What is Yi Guan Jian?
Yi Guan Jian (“Linking Decoction” or “One-Linking Decoction”) is the principal Chinese herbal formula for Liver Yin and Blood deficiency with Liver Qi stagnation. Devised by the Qing Dynasty physician Wei Yu-huang, it represents a refined approach to the common clinical problem of using Qi-moving herbs in Yin-deficient patients — ordinary Liver-spreading formulas (e.g., Xiao Yao San) further damage the Yin, while pure Yin tonics do not address the stagnation. Yi Guan Jian solves this with a base of six Yin-nourishing herbs and a single carefully chosen Qi-mover, Chuan Lian Zi.
Yi Guan Jian TCM pattern
Prescribed for Liver Yin and Blood deficiency with Liver Qi stagnation, characterised by: dull hypochondriac pain, chest distension, dry mouth and throat, acid reflux, dry stools, irritability, a red tongue with little or no coat, and a thin wiry pulse. Often seen in chronic liver disease, post-menopausal women, and after prolonged stress with depletion.
