WCH8.9 - 1689 Zhi Gan Cao Tang

Explanation of Composition According to Traditional Chinese Medicine (TCM) Principles

TCM Purpose:
Zhigancao is traditionally considered in TCM to support Qi and the circulation of channels. It is the main herb in this formula, working together with Ren Shen and Da Zao, which traditionally support the Spleen and Heart. Sheng Di and Mai Men Dong are used to nourish Yin and blood. Gui Zhi and Sheng Jiang are seen as warming herbs that support Yang and the flow of internal pathways. The combination is considered warming without being overly drying and supports Yin while remaining light in nature. It aims to harmonize Qi, blood, and Yin.

Traditional Usage in China (TCM terminology):

• Supports Qi and blood (“buqi yangxue”)

• Nourishes Yin and promotes circulation (“ziyin fumai”)

• Supports the Heart and stabilizes internal rhythms (“buxin dingji”)

Traditional TCM Indications:
According to TCM sources, the formula is traditionally used for:

• Various types of chest obstruction (xiongbi) linked to deficiency of Heart Qi and Yin

• Palpitations or irregular internal rhythms

• TCM-characterized shortness of breath, sleep disturbances, restlessness, dryness of mouth and throat

• Menstrual irregularities and TCM-defined internal deficiency states

• Difficulty falling asleep, dream-disturbed sleep, forgetfulness

• Dry stool, weight loss – particularly in elderly individuals

• TCM pulse characteristics such as knotty (jie), intermittent (dai), or weak/thready (ruo, xi) pulses

• Tongue appearance: pale or pink with little to no coating

• TCM patterns related to long-term dry cough, dryness of the throat, thirst, night sweating, general dryness, shortness of breath, and internal heat – especially when worsened by overwork
