Yongquan Point (KI1): The Hidden Wellness Treasure at Your Sole
In the TCM meridian system, Yongquan point belongs to the Foot Shaoyin Kidney Meridian and serves as its starting (Well/Jing) point. It is acclaimed as the "second heart" of the human body. Located in the depression on the anterior sole, it maintains close connections with the central nervous system and constitutes the core acupoint for nourishing yin, tonifying the kidney, calming the spirit, and promoting sleep.
I. Precise Location of Yongquan Point
Standard Position: Yongquan is located in the depression on the anterior plantar surface, at approximately the junction between the anterior 1/3 and posterior 2/3 of the line connecting the web of the 2nd-3rd toe cleft and the center of the heel.
Quick localization:
When toes are flexed, a visible depression appears on the sole
The area anterior to this depression is Yongquan point
Approximately at the anterior 1/3 of the sole
Anatomical basis: Distributes the medial plantar nerve and branches of the medial plantar artery—closely connected to central nervous system regulation.
II. Major Therapeutic Functions of Yongquan
1. Improves Insomnia & Vivid Dreams
Applicable symptoms: Difficulty falling asleep, shallow sleep, easy waking with vivid dreams
Mechanism: TCM holds that "Kidney stores essence, essence generates marrow, marrow communicates with the brain." As the Kidney Meridian's starting point, Yongquan stimulation regulates the nervous system and improves sleep quality.
Clinical outcome: Continuous massage for 1 month improves sleep quality in individuals with neurasthenia.
2. Relieves Dizziness & Fatigue
Applicable symptoms: Chronic fatigue, lack of energy, dizziness, lightheadedness
Mechanism: Tonifies kidney-essence, replenishes marrow, improves cerebral perfusion and oxygenation.
3. Adjunctive Blood Pressure Regulation
Applicable symptoms: Hypertension, hypotension
Mechanism: Bidirectionally regulates vascular tone; suitable for daily wellness in hypertensive populations.
4. Nourishes Yin & Tonifies Kidney
Applicable symptoms: Lumbar soreness, knee weakness, tinnitus, night sweats, five-palm heat (heat sensation in palms, soles, and chest)
Mechanism: Yongquan is the Kidney Well point; stimulation activates kidney-qi, nourishes yin, and lowers fire.
III. Detailed Massage Techniques
Recommendation by Dr. Chen Cheng, Chengdu University of Chinese Medicine Affiliated Hospital:
Method 1: Push-Kneading (Recommended)
Perform after warm-water foot soak before bedtime
Use thumb pad to push-knead from Yongquan toward the heel
Each session 3–5 minutes, alternate sides
Goal: sole feels warm/hot
Method 2: Point-Pressing
Use thumb pad to apply vertical pressure to the acupoint
1 minute per side; pressure should produce soreness
Goal: sole feels warm/hot
Method 3: Rubbing-Scrubbing
Use hypothenar eminence (palm base) to scrub Yongquan rapidly
Scrub fast until sole becomes warm/hot
2–3 minutes per session

VII. Yongquan & Longevity
Folk wisdom states: "If you wish elders to remain well, keep Yongquan consistently warm."
