Description
Wen Dan Tang (Warm the Gallbladder Decoction) treats disharmony of the Gallbladder and Stomach with phlegm-heat. Despite its name, the formula does not warm but rather transforms phlegm and clears heat from the Gallbladder. It is widely used for sleep disorders, anxiety, palpitations, and nausea caused by phlegm-heat disturbing the Heart and Gallbladder.
