Yongquan (KI 1)

Point Jing (Well) of the Kidney, Wood point.

Location of Yongquan

Imagine a vertical line that divides the foot in 2 and passes through the 2nd^⁠ toe, under the sole of the foot (between the metatarsals and the heel). Divide this line into 3 parts;  Yongquan is located 1/3 behind the metatarsal heads, i.e. 2/3 in front of the heel.
You can ask the patient to curl the toes: a depression will form. Yongquan is at the center of this depression.

Therapeutic functions of Yongquan

• Yongquan opens the orifices, awakens the Mind and clears Heat: syncope, coma;
• Lowest point of the body: it lowers Yang/Fire (especially when Liver Yang rises too much) in case of excessive rising of Yang/Fire.
  In case of hypertension due to rising Yang, insomnia + 'pressure-cooker' syndrome;
• This point is warmed to tonify Kidney Yang or to nourish Yin, but mostly for Yang (walking barefoot on a cold floor can damage Yang);
• It controls internal Wind, as it is a Wood point.
