Commentary for Danshu BL-19

Danshu BL-19 is a major point of the Bladder Channel with various functions. 

As the Back Transporting-Shu point of the Gall Bladder, it resolves Damp-Heat in the Gall Bladder and Liver. Therefore it is able to treat cholecystitis, yellow sclera, bitter taste and jaundice.

The Gall Bladder is a part of the Lesser Yang, thus BL-19 can expel Pernicious Factors from the Lesser Yang Stage of the Six Stage Theory or eliminate Gall Bladder Heat within the Four Levels Theory. It regulates the Lesser Yang and can be used for symptoms such as alternation of feeling of heat and cold, dry throat, blurred vision and hypochondrial distension. 

Furthermore, it tonifies the Gall Bladder Qi and has some calming effect. Patients with Gall Bladder Qi Deficiency tend to be timid, undecisive and depressed. 

Danshu BL-19 also subdues Rebellious Stomach Qi, characterized by symptoms such as vomiting, difficult swallowing, belching, nausea as well as pain and distension of the chest and hypochondrium. 

Finally, it has a powerful effect in tonifying general Deficiency, especially the Yin Deficiency. Typical symptoms are night sweating, fever, dry throat and the feeling of 'steaming bones'.
