Jiexi (ST41): The Stream Divides Point for Stomach Heat and Ankle Recovery

Introduction to Jiexi

Jiexi (解溪 ST41), meaning “Stream Divides” or “Relieving Stream,” is the Jing-River point of the Stomach Meridian of Foot-Yangming. Located at the front of the ankle, it sits at a natural dividing line where the foot meets the leg — a place where Qi “divides” and flows between the upper and lower body.

The name reflects both its anatomy and function. The ankle is where tendons and vessels cross and “divide” like streams branching from a river. Clinically, Jiexi “relieves” by clearing Stomach heat, resolving dampness, and restoring mobility to the ankle joint.

As a Fire point on an Earth meridian, Jiexi carries a unique energetic signature. The Stomach (Earth) generates Fire, making Jiexi a place where Stomach energy naturally expresses its most active, warming aspect. This explains its effectiveness for heat-related conditions of the Stomach channel, including toothache, swollen gums, and abdominal fullness.

Location

Jiexi is located at the front of the ankle:

• Standard location: On the dorsum of the foot, at the midpoint of the transverse crease of the ankle joint, between the tendons of extensor digitorum longus and extensor hallucis longus
• Easy method: Bend your ankle upward (dorsiflex). The point is in the middle of the horizontal crease that forms at the front of the ankle, between the two visible tendons

Key Functions

1. Clear Stomach Heat (清胃热)

Jiexi is a powerful point for clearing heat from the Stomach channel. As a Fire point, it has an inherent ability to regulate the heating aspect of Stomach energy. When Stomach heat rises upward along the channel to the face and head, Jiexi intercepts and clears it.

2. Resolve Dampness and Phlegm (化痰除湿)

The Stomach is the primary organ of digestion, and dampness is its most common pathogen. Jiexi helps resolve dampness accumulation that causes abdominal fullness, bloating, and heavy sensations.

3. Relax Sinews and Alleviate Ankle Pain (舒筋活络)

As a local point at the ankle joint, Jiexi is essential for treating ankle stiffness, sprains, and restricted movement. It helps restore the smooth flow of Qi and Blood through the joint.

4. Calm the Spirit (安神)

Through its connection to the Stomach (which generates the material basis for mental activity in TCM theory), Jiexi can help calm restlessness and anxiety that arise from Stomach disharmony.

Clinical Applications

Toothache and Swollen Gums

Stomach heat rising along its channel to the upper jaw is one of the most common causes of toothache with swelling. Jiexi is a distal point that clears this heat at its source, providing relief for:

• Throbbing toothache
• Red, swollen, or bleeding gums
• Bad breath with a bitter taste

Typical pattern: Toothache worsens with heat, swollen gums, thirst, preference for cold drinks.

Abdominal Fullness and Bloating

When food stagnates and generates heat in the Stomach, causing a feeling of fullness, Jiexi helps restore the normal descending function of Stomach Qi.

Ankle Sprain and Stiffness

Jiexi is a key point in any ankle treatment protocol:

• Acute sprain: Reduces swelling and promotes circulation
• Chronic stiffness: Restores range of motion
• Post-injury rehabilitation: Supports full recovery

Headache and Dizziness

Stomach heat can rise to the head, causing frontal headaches and a heavy, dizzy sensation. Jiexi addresses this by clearing the heat from its origin.

Constipation with Heat

When constipation is accompanied by abdominal fullness and heat signs, Jiexi helps by clearing Stomach heat and promoting the downward flow of Qi.

Acupressure Self-Care

For Toothache and Facial Heat

1. Sit or stand comfortably with your foot accessible
2. Bend your ankle upward to expose the front crease
3. Locate Jiexi in the center of the ankle crease between the tendons
4. Apply firm, steady pressure with your thumb for 1–2 minutes
5. Breathe deeply and visualize heat draining from the face down through the leg
6. Repeat on the opposite side

For Ankle Recovery

1. Apply gentle circular pressure on Jiexi
2. Slowly rotate the ankle through its full range of motion while maintaining contact
3. Spend 2–3 minutes per ankle
4. Repeat 2–3 times daily, especially before and after activity

Intensity Guidelines

Goal	Pressure	Duration
Toothache and heat	Moderate to firm	1–2 min per ankle
Ankle recovery	Gentle to moderate	2–3 min per ankle
Digestive support	Gentle	1 min per ankle

Combination Points

Jiexi works well in combination with other points:

Combination	Purpose
Jiexi + Hegu (LI4)	Clear Stomach and Large Intestine heat — powerful for toothache
Jiexi + Neiting (ST44)	Clear Stomach heat — enhanced effect for gum swelling and bad breath
Jiexi + Zusanli (ST36)	Regulate Stomach function — digestive harmony
Jiexi + Kunlun (BL60)	Comprehensive ankle treatment — pain and stiffness

The Stomach Channel and Facial Pain

Understanding why Jiexi treats toothache requires knowing the Stomach meridian’s pathway:

1. The Stomach channel begins at the face (below the eye)
2. It travels through the upper and lower gums
3. It wraps around the mouth and travels up to the forehead
4. It then descends through the torso and leg to the foot

This is why Stomach heat so often manifests as dental pain, gum swelling, and facial heat — the channel literally passes through these areas. Jiexi, at the foot, is a distal point that treats the origin of the heat while simultaneously affecting the entire channel.

Moxibustion Notes

• For cold patterns: Moxibustion on Jiexi warms the Stomach and dispels cold — useful for chronic ankle stiffness that worsens in cold weather
• For heat patterns: Avoid moxibustion; use acupressure or gentle needling instead
• Method: Hold a moxa stick 2–3 cm above the point for 5–10 minutes

Precautions

• Pregnancy: Use with caution; the Stomach meridian has points that can affect pregnancy
• Ankle injury: In acute sprain with significant swelling, use gentle pressure only — avoid deep or forceful manipulation
• Needling caution: Avoid deep penetration that could damage the dorsalis pedis artery

Key Takeaways

• Jiexi (ST41) is the Jing-River point of the Stomach Meridian, located at the front of the ankle
• As a Fire point on an Earth meridian, it excels at clearing Stomach heat
• It is highly effective for toothache, swollen gums, and facial heat caused by Stomach fire
• It is an important local point for ankle sprains, stiffness, and rehabilitation
• Understanding the Stomach channel pathway explains its effectiveness for dental and facial conditions
