In conventional medicine, the lungs and the stomach belong to entirely different systems. However, anyone who has ever felt breathless after a big meal or lost their appetite during a cold knows that the body doesn’t always follow textbook divisions. In traditional Chinese medicine (TCM), the connection between breath and digestion is a widely accepted principle, and the acupoint Qi Door (Qi Hu, ST13) is a great example.
Ancient Functionality: The Qi Gateway
Qi Hu is first mentioned in the “Zhen Jiu Jia Yi Jing” (“A-B Classic of Acupuncture and Moxibustion”), which is one of the oldest and most authoritative texts in TCM. Similar to other acupuncture points that have “door” or “gate” in their names, Qi Hu regulates the entry and exit of vital energy, known as qi, between the external environment and the energetic pathway (meridian) associated with the acupoint.
Practical Benefits
Located on the Stomach meridian, Qi Hu plays a key role in managing the flow of qi into and out of this energy channel. Due to this function, Qi Hu is often used as a preventive point to maintain digestive health. Additionally, it aligns with a fundamental principle of TCM, which states that an acupoint can help address issues in its immediate area—in this case, the chest. This explains its frequent use for conditions such as shortness of breath, chest tightness, wheezing, and localized pain. Some practitioners rely on it preventatively, especially during seasonal transitions or flu outbreaks.
What Science Says: A Neurological Connection
Modern science is beginning to investigate the physiological mechanisms behind the effectiveness of acupuncture, in general, and Qi Hu specifically. One review examined how acupuncture affects the autonomic nervous system, which controls involuntary body functions such as breathing, digestion, and heart rate. Findings suggest that specific acupoints—including Qi Hu—can influence this system.
In animal studies, stimulating Qi Hu has been shown to enhance gastric motility and improve digestion. Stimulation of the point increased activity in the vagus nerve, which promotes the “rest-and-digest” state in the body. Additionally, it slightly inhibited the sympathetic nervous system, which can slow digestion when it is overactive.
How to Locate and Stimulate Qi Hu
To locate Qi Hu, start by finding your collarbone. Measure four finger widths outwards from the center of your chest, and you should be near the midpoint of your collarbone. Gently press around the lower edge of the collarbone. If you discover a sore or tender spot, you have likely found the acupoint. These sensations suggest that you are activating the acupoint, and your body is responding to the acupressure.
How to Stimulate Qi Hu
- Firm pressure: Press firmly for three to five seconds, then relax for three seconds. Repeat for one to three minutes on each side.
Circular massage: Massage in small circles with your index finger or thumb for one to three minutes on each side.
Herbal patch: Apply an herbal patch overnight for longer activation. - Advanced methods: If you’re working with a trained TCM practitioner, acupuncture or moxibustion can deepen the effects—but due to the lung’s proximity, acupuncture must be shallow and cautious.
Precautions
Avoid this point if you have a physical injury in the area. Always test herbal patches on a small patch of skin first, especially if you have sensitive skin. Because Qi Hu sits near the lungs, deep needling is not recommended. If you’re using it during a cold or flu, give yourself a shoulder massage first to open up the chest region and make stimulation more effective.
A Simple Tool for Daily Self-Care
When you’re battling shortness of breath, seasonal lung issues, or just feel like your digestive system is dragging, consider trying Qi Hu. It’s easy to reach, safe for self-care, and can be a surprisingly effective support for both breath and belly. Sometimes, all it takes is opening the right door.
