All 12 meridians
Called the 'Great Harmonizer' (Guo Lao — 'respecter of the elderly' for its gentle longevity), licorice enters all twelve meridians and moderates the nature of every formula it joins. Present in the majority of classical Chinese prescriptions, it also stands alone as a spleen tonic, lung soother, and natural sweetener.
