In recent years, gut health and its impact on various parts of the body have been all the rage. Before you invest another hefty sum in the latest probiotics or trendy supplements, consider a time-honored holistic self-care tool from traditional Chinese medicine (TCM). The Branch of the Upright (Zhi Zheng, SI7) is an acupoint located on your forearm. Part of the Small Intestine meridian, it offers benefits that go beyond simple digestive support.
The TCM Principles Behind Zhi Zheng’s Reach
First described in the “Ling Shu” (“Spiritual Pivot”), an essential TCM classic, Zhi Zheng is identified as the Luo-Connecting Point. In TCM theory, Luo points act as bridges, linking the energy and blood flow between paired meridians (energy pathways). Specifically, Zhi Zheng connects the Small Intestine meridian with the Heart meridian, its interior-exterior pair. When the Small Intestine meridian is energetically deficient, qi (vital energy) from the Heart meridian flows into Zhi Zheng, making this point particularly effective for normalizing the circulation of blood and energy in both meridians.The heart and the small intestine govern more than just circulation and digestion—they are central to emotional stability and the well-being of “shen,” or spirit. This is why Zhi Zheng has traditionally been used for serious mental disturbances, including mania, uncontrollable laughter, and a mix of fear and sadness with intrusive thoughts. Some modern mental health professionals may label these symptoms as generalized anxiety or mood disorders.
The anatomical location of the Small Intestine meridian plays a significant role in its functions. Since this meridian runs up the arm to the head, stimulating the Zhi Zheng point effectively addresses headaches and neck stiffness, particularly when these issues are linked to emotional stress or blockages in the meridians.
Moreover, this point helps eliminate damp heat from the digestive system, a common underlying cause of acne, oily skin, and breakouts, especially during puberty. By stimulating Zhi Zheng, the body can better absorb nutrients and process fluids, leading to clearer skin.
Backed by Research
Modern research is beginning to confirm these classical insights. In one study, electroacupuncture at Zhi Zheng and Shenmen (HT7), an acupoint on the heart meridian, was tested on rabbits with acute myocardial ischemia. Electroacupuncture significantly improved heart rate, heart function, and the nerve activity related to stress, with improvements within 10 to 20 minutes. Although the acupoint on the Heart meridian had a slightly stronger effect, Zhi Zheng still produced measurable cardiovascular benefits, supporting its traditional link to the Heart meridian.In another study focused on irritable bowel syndrome (IBS), researchers compared the pain thresholds of digestive-related acupoints in IBS patients versus healthy individuals. Zhi Zheng stood out as one of the most sensitive and reactive points in IBS patients, indicating that Zhi Zheng is not only tied to digestive function but also responds to disruption in the normal function of the digestive organs, making it a useful diagnostic and therapeutic tool.
How to Locate and Activate Zhi Zheng
Place your palm face down and identify the midpoint between your wrist and elbow on the outer side of your arm, near the side of your pinky finger. Move one finger’s width towards your wrist from the halfway point. The Zhi Zheng acupoint is found in the groove between the outer edge of the forearm bone and the flexor carpi ulnaris muscle, which runs to the wrist.Easy Techniques to Activate Zhi Zheng
- Pressure: Apply firm pressure for five to six seconds, relax for three seconds, and repeat for one to three minutes per side.
- Massage: Use your thumb to apply gentle pressure in a circular motion. Gradually increase the intensity of the massage to ensure effective stimulation within your comfort levels.
- Herbal Patch: For a prolonged effect, apply an herbal patch overnight.
Precautions
Avoid stimulating this point if there’s an injury, inflammation, or skin irritation in the area. If using an herbal patch, avoid artificial chemicals or harsh additives if you have sensitive skin.One Point, Many Uses
Zhi Zheng offers something for everyone. For older adults, it can be used to support cardiovascular function. For working professionals, it helps with mental clarity and emotional balance in the face of daily stress. For teenagers, it offers a holistic tool against skin breakouts. This acupoint may become a household staple. Keep it in your self-care arsenal and share it with those who can benefit from its wide-ranging effects.TCM expert Shihhsiang Hung reviewed this article for accuracy and clarity.
