Commentary for Yingu KID-10

Yingu KID-10 has two major functions. 

First of all, it resolves Dampness from the Lower Burner, like the other two Sea-He points around the knee: Yinlingquan SP-9 and Ququan LIV-8. Typical symptoms are urinary or abdominal disorders such as hypogastric pain and fullness, abdominal distension and pain, difficult urination, turbid urine as well as painful urination. 

The point is also often used to nourish Kidney Yin. Typical manifestations include backache, tinnitus, deafness, night sweating, dark urine and dry throat. 

Zhaohai KI-6 and Zhubin KID-9 also deal with Kidney Yin Deficiency. However, KID-6 is more focused on moistening the Dryness while KID-9 is more on treating mental emotional issues such as anxiety and insomnia. All above symptoms are the consequences of Kidney Yin Deficiency.
