Would you believe that there’s an acupoint on your foot that can solve digestive problems? The Gongsun (恭敬, SP4) acupoint is exactly that—a point trusted in traditional medicine for ages. Specifically, when digestion is sluggish, you suddenly feel nauseous, or you’re suffering from abdominal pain, pressing this point with your finger can bring surprisingly rapid symptom relief.
This article explains step-by-step how to find the precise location of Gongsun, the correct acupressure technique, and its effects and precautions. It’s structured so you can follow along and try it right now.
What is the Gongsun Acupoint?
SP4 (Gongsun) is an acupoint on the Spleen meridian and is key to digestive function and immune health.
The name “Gongsun” comes from the appearance of the big toe when it’s flexed. In traditional medicine, the Spleen goes beyond just being a digestive organ—it is responsible for nutrient absorption, blood production, and immune function. Stimulating Gongsun activates all of these functions.

Finding the Precise Location of Gongsun
Finding the exact location accounts for 80% of the effectiveness. It may seem difficult at first, but after finding it once or twice, you’ll become familiar with it quickly.
Step-by-Step Method to Locate the Point
- Examine the inner side of your foot: Sit comfortably and place one leg over the other so you can see the sole of your foot.
- Check below the big toe: Look at the area below the big toe, toward the heel direction.
- Find the depression: When you flex your big toe upward, a crease forms and beneath it is a small indentation. That’s Gongsun.
- Confirm the sensitive point: Gently press with your finger and locate the point that responds most sensitively.
- Check both feet: Both the left and right feet have the acupoint in the same location.
Tip: If you have difficulty finding it at first, try repeatedly moving your big toe up and down. During movement, the point beneath the most prominent bone, at the inner edge of the foot, is Gongsun. When you press it, you should feel some discomfort or a heavy sensation to confirm you’ve found the correct spot.
Correct Method for Applying Acupressure to Gongsun
The intensity, duration, and technique of acupressure determine its effectiveness. If applied too lightly, you won’t see results; if too forcefully, you may feel fatigue.
5-Step Acupressure Technique
- Prepare your posture: Sit or lie down comfortably and relax any tension. Choose a position where you can move your toes freely.
- Locate Gongsun: Confirm the location of Gongsun once more with your finger and flex your big toe upward.
- Apply pressure: Slowly press Gongsun with your thumb or index finger. Maintain a pressure level that is “slightly painful but tolerable” (pain level 3-5/10).
- Choose your stimulation method:
- Method A: Repeatedly press and release the same point for 3-5 seconds each (total 1-2 minutes)
- Method B: Slowly massage in small circular motions (clockwise direction, 1-2 minutes)
- Apply to both feet: Apply the same pressure intensity to both the left and right feet.
Sensations you should feel during acupressure: When pressing Gongsun, you should experience at least one of these: “a sensation of tension releasing,” “a heavy ache,” or “a warming feeling.” This indicates you’re stimulating the correct point.

Primary Effects of Gongsun Acupressure
Gongsun acupressure offers wide-ranging effects from the digestive system to women’s health.
Effects by Symptom
- Relieves indigestion: Activating the Spleen meridian promotes the secretion of digestive enzymes and normalizes the rate at which food moves from the stomach to the small intestine. You may feel improvement within 30 minutes to 1 hour after acupressure.
- Rapidly resolves nausea: It works fastest for motion sickness, stomach-related nausea, and post-meal nausea. Based on clinical experience, symptom relief is possible within 3-5 minutes.
- Improves abdominal pain and diarrhea: It calms excessive intestinal motility to relieve abdominal pain and normalizes bowel function to reduce diarrhea.
- Alleviates menstrual cramps: It improves blood circulation in the lower abdomen, relieving the stagnation (blood stasis) that causes menstrual pain. Regular acupressure from before the start of your period is even more effective.
- Enhances immunity: In traditional medicine, the Spleen is the center of “postnatal qi” generation. Regular stimulation increases overall stamina and immune function.
- Promotes recovery from fatigue: Improved digestion leads to better nutrient absorption, which translates to increased energy production.
Related Information: If you have multiple abdominal symptoms, stimulating ST36 (Zusanli) along with Gongsun can produce a synergistic effect. Zusanli is known as a “universal acupoint” for immunity and overall health.
When and How Often Should You Apply Acupressure?
The effectiveness of acupressure is determined by timing and frequency.
Optimal Time for Acupressure
Spleen Meridian Active Hours: 7-9 AM
In traditional medicine, organs are believed to activate at specific times during the day. The Spleen meridian is most active in the morning from 7-9 AM, so acupressure applied during this time maximizes effectiveness. Of course, if you have acute symptoms, you can apply pressure at any time.
Acupressure Frequency by Situation
| Situation |

Caution: Stimulating the same area too frequently can actually lead to fatigue. It’s best not to apply acupressure more than 3 times per day.
Precautions When Applying Acupressure to Gongsun
Be sure to check these before applying acupressure. This maximizes effectiveness and prevents adverse effects.
Situations to Avoid
- When there are wounds or inflammation on the foot: Avoid that area and apply pressure elsewhere. If you have a skin condition or infection, wait until it’s fully healed before applying acupressure.
- During pregnancy: Although Gongsun is a relatively safe acupoint, pregnancy is a very sensitive state for the body. Always consult with a traditional medicine practitioner before proceeding. (Certain acupoints such as Sanyinjiao (SP6), Hegu (LI4), and Taichong (LR3) are contraindicated in pregnancy.)
- During high fever or acute inflammation: If you have a high fever due to infection or acute inflammation, first consult a healthcare professional.
- During extreme fatigue: Acupressure applied during extreme exhaustion can cause additional fatigue.
Maintaining Proper Acupressure Intensity
Weak pressure yields no effect, while excessive pressure can backfire. Use the following as guidelines for adjustment:
- “Slightly painful but tolerable” level (pain 3-5/10)
- A level that poses no risk to blood vessels or nerves
- Some redness in the treated area after acupressure is normal, but bruising indicates excessive pressure
Hygiene Management
- Wash hands and feet before and after acupressure: Cleanse your hands and feet thoroughly before starting.
- Check fingernail length: If your nails are long, use the joint of your finger or your knuckle instead of the fingertip.
- Using tools: If your fingers become sore, you can use an acupressure tool or massage device.
If Symptoms Worsen After Acupressure
Within 1-2 days after acupressure, you may experience temporary symptom exacerbation (a healing response). This is normal. However, if symptoms persist for more than 3 days or become more severe, consult a traditional medicine practitioner or physician.
Relationship with Food Intake
Apply acupressure at least 30 minutes after eating. Applying pressure immediately after eating can interfere with the digestive process. The ideal time is when your stomach is empty or after sufficient time has passed following a meal.
When Do You Need to Consult a Healthcare Professional?
- Chronic indigestion: If there’s no improvement after 2-3 weeks of acupressure, you need to identify the underlying cause.
- Bloody stool or dark-colored stool: This is a sign of an intestinal condition and requires immediate medical evaluation.
- Persistent abdominal pain: This could indicate an acute condition such as appendicitis.
- Menstrual cramps different from usual: A new condition such as uterine fibroids may have developed.
- Severe nausea and vomiting: This could be a sign of infection or neurological disorder.
Pregnancy Warning: If you are pregnant or there is a possibility of pregnancy, be sure to consult a traditional medicine practitioner or healthcare professional before applying acupoint stimulation. Although Gongsun is relatively safe, certain acupoints such as Sanyinjiao (SP6), Hegu (LI4), and Taichong (LR3) can trigger uterine contractions.

Related Acupoints to Know About with Gongsun
If you have digestive symptoms, stimulating these acupoints along with Gongsun can be even more effective:
- Zusanli (ST36): Located on the front of the leg below the knee, it manages immunity and overall health. Stimulating it together with Gongsun doubles the digestive improvement effect.
- Neiguan (PC6): Located on the inner forearm in the middle, it is most effective for resolving nausea. It’s commonly used by people suffering from motion sickness.
- Sanyinjiao (SP6): Located on the inner side of the ankle, it excels at promoting women’s health and alleviating menstrual cramps. (However, it is contraindicated in pregnancy.)
