Notes:

Despite only Zhongzhu SJ-3 mentioning benefiting the eyes, the indications for this point include redness, swelling and pain of the eyes. As the fire point it can be understood to clear Heat in the whole channel including the eyes. This extends to its internal branches deep inside the body clearing Heat from all three Jiao giving its other indications for moving stool and benefiting the chest and throat by clearing Heat.
