Ren 8, also known as Shenque or the “Spirit Gate,” is a vital acupuncture point located at the center of the umbilicus. Unlike most acupuncture points, Ren 8 is not typically stimulated through needling due to its delicate location. Instead, moxibustion and other non-invasive techniques are used to harness its therapeutic potential.

Ren 8 Acupoint and Moxibution Location
Ren 8 is located in the center of the navel, making it a distinct point in traditional Chinese medicine. This point is directly associated with the body’s core energy and is believed to influence vitality and overall health.
Why Moxibustion for Ren 8?
Moxibustion, the practice of burning dried mugwort (moxa) near or on specific points, is the preferred method of stimulating Ren 8. This approach is chosen because:
- Safety: The umbilical area is sensitive and unsuitable for needling.
- Warming Energy: Moxibustion provides a deeply penetrating warmth that invigorates the Yang Qi and nourishes the body’s core.
- Improved Circulation: It enhances blood flow and energy movement in the abdomen.
Therapeutic Benefits
Ren 8 is often used in cases of:
- Digestive Issues: Supports conditions such as diarrhea, bloating, and abdominal pain.
- Cold Syndromes: Warms the body to alleviate cold extremities and symptoms of Yang deficiency.
- Shock and Collapse: Traditionally applied in emergencies to restore consciousness and strengthen vital energy.
Practical Application
For practitioners, applying moxa to Ren 8 involves:
- Preparation: Clean the area around the umbilicus to ensure hygiene.
- Moxa Stick or Cone: Use indirect moxibustion by holding a lit moxa stick close to the point or placing a moxa cone on a slice of ginger or salt for insulation.
- Monitoring: Carefully observe the patient for comfort and avoid overheating, no longer than 5 minutes.
Research on Ren 8
A study published in a 2010 issue of “The Journal of Chinese Medicine” highlights the effectiveness of quick cupping on Shenque REN-8 through three cases, demonstrating its versatility in treating different conditions.
In the first case, a man with acute asthma experienced symptom relief after rapid cupping (30 times per minute) on REN-8, supplemented by acupuncture. The second case, involving a man with intractable hiccups due to upward reversal of Stomach qi, showed resolution after 10 minutes of quick cupping at REN-8 and complementary acupuncture.
The third case, a young woman with abdominal pain and diarrhea caused by cold food, saw pain relief after 7 minutes of cupping at REN-8, with full recovery after additional acupuncture. These cases illustrate how cupping at REN-8 regulates qi, addressing various ailments like asthma, hiccups, and acute enteritis.1
Ren 8 and Senility
This study examines the impact of suspended moxibustion at Shénquè (CV 8) on reducing senile symptoms and its potential mechanism. Sixty-three patients were divided into a moxibustion group and a control group, with the moxibustion group receiving treatment over CV 8 for 30 minutes every two days over two months.
Results showed significant reductions in senile symptoms, such as lumbar debility and insomnia, in the moxibustion group compared to the control group (P<0.05). Additionally, serum melatonin levels increased significantly in the moxibustion group (P<0.001), correlating with symptom improvement.2 The findings suggest that moxibustion at CV 8 effectively reduces senile symptoms, likely through the elevation of serum melatonin levels.
