In traditional Chinese medicine (TCM), the distinction between physical and mental health is not as pronounced as in conventional medical approaches. The same acupoint that alleviates heart discomfort can also help ease emotional turmoil.
One such versatile acupoint is Intermediary Messenger (Jian Shi, PC5). This point is known for its effects on the heart and its ability to promote a sense of peace. It exemplifies TCM’s treatment of the body as an integrated system. Let’s explore why Jian Shi has been used for centuries to address both heartache and heart health.
The Classical Role of Jian Shi in TCM
Jian Shi was first mentioned in the “Ling Shu,” also known as the “Spiritual Pivot,” a foundational text in acupuncture and Chinese medical theory. This acupoint is particularly significant as a Jing River point. In TCM, Jing River points are areas where the flow of blood and energy becomes more forceful and heavy. These points are often utilized to treat disorders related to muscles, bones, and joints around the acupoint and expel pathogenic factors like heat or wind.
As part of the Pericardium meridian, which plays a vital role in protecting the heart, Jian Shi is closely linked to cardiovascular health. It is frequently used to address issues such as chest tightness and palpitations. Furthermore, it can help relieve symptoms such as nausea and an upset stomach, which TCM associates with disrupted qi, or the vital energy flow in the body. Blood and qi are interconnected—therefore, ensuring a smooth flow of one affects the other. By regulating the flow of blood, we can also promote the proper flow of qi in the body.
Beyond its physical applications, Jian Shi is also known for its ability to “calm the spirit.” TCM practitioners describe this function as a way to support emotional regulation. When someone experiences irritability and restlessness due to feelings of dissatisfaction, stimulating Jian Shi is believed to help restore a sense of inner calm and equilibrium.
Science Catches Up to Ancient Intuition
In modern research, Jian Shi’s influence on both body and mind has been mapped out through controlled studies. One such study explored how electrical stimulation at Jian Shi and Nei Guan (PC6), another acupoint on the Pericardium meridian, affected healthy young men.
The sudy revealed that the intervention increased heart rate and overall cardiac workload, likely due to a boost in sympathetic nervous activity—our body’s built-in “alert” system. While this shows a real-time physiological shift, the researchers noted that it didn’t significantly change oxidative stress levels, meaning its long-term cardiovascular protection is still being explored.
Another study delved deeper into how different acupoints affect the autonomic nervous system—the body’s control panel for stress and relaxation. When Jian Shi was stimulated, researchers noticed increased parasympathetic activity. This system governs the “rest and digest” response, suggesting that Jian Shi can help dial down stress and restore calm.
How to Locate and Stimulate Jian Shi
Finding Jian Shi is relatively easy. Extend your arm with your palm facing up. From the crease of your wrist, measure about four finger widths up the forearm. The point is located between two visible tendons: the palmaris longus and the flexor carpi radialis. If you press between them, you may feel a slight dip—that’s Jian Shi. The sensations of soreness or tenderness indicate that you’ve found the right spot.
How to Stimulate Jian Shi at Home
You can activate this acupoint on your own with minimal effort:
- Press: Press down firmly for three to five seconds, then release for three seconds. Repeat this cycle for one to three minutes on each wrist.
- Massage: Use your thumb or index finger to make slow, steady circles on the point for one to three minutes.
- Herbal Patch: Apply an herbal patch to the area overnight for sustained stimulation.
For deeper therapeutic results, consult a trained TCM practitioner for acupuncture, moxibustion (a gentle heat therapy with dried mugwort), or cupping.
Precautions
Although acupressure is generally safe and easy to access, avoid applying manual pressure to Jian Shi if you have any injuries, bruises, or inflammation in that area. When using herbal patches, choose formulas made with natural ingredients, especially if you have sensitive skin or a history of irritation.
The Case for Consistent Self-Care
Some people find it difficult to see the connection between heart palpitations and emotional irritability, or between the pericardium and peace of mind. However, Jian Shi has stood the test of time in TCM because of the dual effects it has observed on mental and physical balance. If you’re curious, try stimulating the point regularly and simply notice how your body and mind react. There’s nothing to lose—and possibly a newfound sense of calm to gain.
