Commentary for Guangming GB-37

Guangming GB-37's most important function is to benefit the eyes, improve eyesight and eliminates 'floaters' in the eyes, despite of being a distal point. 

It is particularly effective in treating eye disorders caused by Liver Fire Rising as it is able to drive the Fire downwards. 

Furthermore, Guangming GB-37, like many of its neighboring points, can open the Channel by removing the Obstructions. Therefore it is able to treat pain, numbness or even atrophy on the knees or lower legs.
