Hangsok Acupoint (ST43) Precise Location and Effects — Acupressure Methods for Edema and Abdominal Pain Relief

Exact Location of the Xianggu Acupoint

Xianggu (陷谷, ST43) is an acupoint on the Yangming Stomach meridian, located on the top of the foot in the depression behind the metatarsophalangeal joint between the second and third metatarsal bones. The name ‘Xianggu’ literally means ‘sunken valley,’ with ‘Xian’ (陷) referring to the depression and ‘Gu’ (谷) meaning valley, clearly indicating the anatomical characteristics of the location.

Finding the Location Step by Step

1. Natural foot position: Sit comfortably and place one leg over the opposite knee to expose the foot easily.
2. Identifying toe bones: Follow the two visible lines of bones (metatarsals) on the top of the foot with your fingers when the toes are spread apart.
3. Valley location: Find the depression between the metatarsal bones between the second and third toes, just above where the toe bones begin (behind the metatarsophalangeal joint).
4. Confirming the tender point: The exact location of Xianggu is where you feel slight tenderness or soreness when gently pressing with your thumb.
5. Finding it for the first time: You can achieve greater accuracy by looking in a mirror or having another person help you locate it.

Xianggu is particularly effective for the following symptoms because it influences stomach function and facial and upper body circulation:

Correct Method for Applying Xianggu Acupressure

Precise location and appropriate pressure are important for Xianggu. If pressure is too light, it will be ineffective; if too strong, it can cause tissue damage.

Basic Steps for Acupressure

1. Preparation: Sit comfortably and place one leg over the opposite knee to expose the foot.
2. Locating precisely: Position the padded area of your thumb exactly on the Xianggu point.
3. Applying pressure gradually: Apply pressure slowly over 3-5 seconds until you feel a soreness or fullness sensation (酸脹感). Avoid sharp pain.
4. Gradual release: Slowly release the pressure at the same pace.
5. Repetition: Repeat the above process 10-15 times.
6. Both feet: Apply the same technique to the other foot.

Tips to Enhance Effectiveness

• Soaking the feet in warm water (40-45°C) for 5-10 minutes before applying acupressure improves circulation for greater effectiveness.
• Drinking plenty of water (warm water or herbal tea) after acupressure promotes metabolism.
• Getting adequate sleep after applying acupressure in the evening enhances the body’s recovery ability.

Frequency and Optimal Timing for Xianggu Acupressure

Recommended frequency: 1-2 times daily for 5-10 minutes each is appropriate. Avoid applying acupressure more than 3 times daily as excessive pressure can irritate tissue.

Optimal Timing by Symptom

• 7-9 AM: The Stomach meridian is most active during this time, making it optimal for reducing swelling and improving digestion.
• 1+ hour after meals: This timing is best when applying acupressure to aid digestion.
• During work breaks (12-1 PM, 3-4 PM): Effective for relieving eye fatigue and headaches.
• 7-9 PM: The second peak activity time for the Stomach meridian, helping to relieve daily fatigue and improve sleep.

Getting started: Begin with 3-5 minutes per session initially, observe your body’s response, and adjust duration accordingly.

Important Precautions When Applying Xianggu Acupressure

Incorrect methods may reduce effectiveness or cause side effects.

When NOT to Apply Acupressure

• When there are wounds or inflammation on the foot: Wait until healed to avoid infection risk.
• When toe bones are broken: Avoid during the healing period.
• During the acute phase of infectious diseases (cold, inflammation): Avoid if high fever or severe inflammation is present.
• During pregnancy: Xianggu may cause uterine contractions in pregnant women, so consult a practitioner of traditional medicine before proceeding.
• When treating chronic or specific diseases: Prior consultation is necessary to avoid drug interactions.

Correct Acupressure Intensity

• Avoid light pressure: Gentle touching is ineffective.
• Soreness is the right level: You should feel soreness or fullness, but not pain that makes you wince.
• Avoid excessive pressure: It can cause tissue damage, bruising, or injury.

Acupoints That Work Well Together With Xianggu

You can enhance Xianggu’s effects or achieve better results by stimulating other acupoints depending on your symptoms. For example, stimulate Sanyinjiao (SP6, three cun above the inner ankle) together with Xianggu for edema improvement, or combine with Taiyang (temple area) for eye fatigue. If your goal is digestive improvement, additionally stimulate Zusanli (ST36, below the knee). [Related article: Comprehensive Guide to Acupoints Effective for Digestive Improvement]

Expected Changes After Xianggu Acupressure

First week (1-3 days): You may notice slight reduction in swelling and a lighter feeling in the legs.

2-3 weeks: Eye fatigue noticeably improves and digestion becomes more regular.

4+ weeks: Consistent acupressure nearly eliminates swelling, and overall body circulation improves.

Since individual responses vary greatly, observe your body’s response by recording changes on a weekly basis.

Daily Habits to Enhance Xianggu Acupressure Effects

• Adequate hydration: Drinking 1.5-2 liters of water daily accelerates swelling reduction.
• Regular exercise: Light walking or stretching promotes blood circulation.
• Adequate sleep: Going to bed before 11 PM enhances the body’s recovery ability.
• Digestive-friendly diet: Avoid overeating and eat mostly warm foods.
