Stimulating acupuncture points can improve or cure diseases. In the West, acupuncture and acupressure are gradually gaining popularity. However, do meridians really exist in the human body? The scientific community has looked at this from different perspectives. In one recent study published by Harvard Medical School, researchers were able to confirm the existence of the “pericardium meridian,” one of the 12 meridians.

Man’s Heart Issues Cured Within a Month

In January, a 28-year-old man came to the clinic of professor Jonathan Liu, a registered acupuncturist.

This young man and his entire family had always been Liu’s patients. He used to have a lot of energy and loved rock climbing. Not long ago, he contracted COVID-19. It started with a fever, cough, and a sore throat. After he spent a while resting, most of his respiratory symptoms subsided. However, he was stuck with lingering chest congestion and fluttering heartbeats (palpitations). When he exercised, his palpitations became more obvious.

The heart discomfort made it difficult for him to rock climb and left him distressed.

After checking his conditions, Liu found that the young man not only experienced palpitations during exercise but also had symptoms of psychological tension. Liu decided to treat him by starting from his pericardium meridian. Liu needled his pericardium meridian and prescribed Chinese herbal medicine. In little more than two weeks, the young man’s heart symptoms were cured, and he was able to rock climb again.

Why were his heart problems cured by treating his pericardium meridian with acupuncture?

The word pericardium is derived from the Latin words “around (peri)” and “heart (cardium).” As its name implies, pericardium is the membrane enclosing the heart. It’s the guard that protects the heart. And “meridian” can be interpreted as a “channel of energy.”

Usually, our emotional ups and downs will cause the energy in the body to fluctuate strongly, which can damage the heart. In Western medicine, we’d talk about the detrimental effects of different hormones triggered by stress. People who are emotionally unstable and often stressed tend to have unhealthy hearts. The negative energy of the SARS-COV-2 virus will also damage the heart after infection. In particular, many people with post-COVID-19 symptoms (long-COVID) often still have residual viruses in their bodies, and these microscopic parasites continue to attack the heart.

The energy of the pericardium meridian can protect the heart from damage and prevent bad energy from entering the heart. When Liu needled the pericardium meridian for this young man, he was strengthening the energy of his pericardium meridian to fight against the viral energy.

According to traditional Chinese medicine, the “heart” doesn’t refer to only the heart itself, but also the person’s state of mind. Therefore, besides treating chest congestion, palpitations, and angina, the pericardium meridian can also improve mental tension and insomnia.

Harvard Study Confirms Existence of Pericardium Meridian

Traditional Chinese medicine places great importance on the meridians, and many concepts of healing are closely related to them. However, the meridians are invisible to the naked eye, so conventional Western medicine still holds reservations about their existence.

However, in March 2021, a paper published in the medical journal Evidence-Based Complementary and Alternative Medicine, a collaboration between Harvard Medical School and the Institute of Acupuncture and Moxibustion of the China Academy of Chinese Medical Sciences (CACMS), observed the possibility of the pericardium meridian’s existence for the first time.

The pericardium meridian is one of the “12 meridians.” It starts in the chest, follows the midline of the forearm, travels to the palm of the hand, and ends at the tip of the middle finger. It has nine acupoints: Tianchi, Tianquan, Quze, Ximen, Jianshi, Neiguan, Daling, Laogong, and Zhongchong (from PC-1 to PC-9).

In the study, 15 healthy volunteers were recruited, and two Chinese physicians marked the pathways and acupuncture points of the pericardium meridian on their hands and arms and used a low resistance detector for further confirmation. Afterward, they injected fluorescein into the volunteers’ pericardium meridians and observed the direction of the fluorescein’s movement with a special camera.

It was emphasized in the study that the fluorescein was injected intradermally—not subcutaneously, intramuscularly, or intravenously—to ensure that it would not disperse into the blood vessels.

The scientists were surprised to find that after the volunteers were injected with fluorescein in the Neiguan (PC-6) point on their wrists, over time, fluorescent lines appeared on most of their arms. These “glowing lines” spread along their arms, all the way to the bend of their elbows. The path of this line is precisely the path of the pericardium meridian.

In other words, starting at the Neiguan (PC-6) Point, the fluorescein follows the pericardium meridian all the way to the Quze (PC-3) Point.

It’s worth noting that the bright spot at the Quze (PC-3) Point appeared even earlier than the fluorescent line, as if the fluorescein entered the body and then “time traveled” to Quze (PC-3) Point. What’s more interesting is that the Quze (PC-3) Point is considered a “He-Sea point” in traditional Chinese medicine. The ancients believed that these kinds of points could gather energy, so, in a way, the results seem to confirm this.

In addition to the Neiguan (PC-6) Point, the researchers also injected fluorescein into one volunteer’s Jianshi (PC-5) Point, and a fluorescent line also appeared. In some cases, the lines extended all the way to the upper arm. This phenomenon lasted for 18 hours before the lines slowly disappeared.

In order to confirm whether similar linear traces would appear if fluorescein was injected at any point on the hand, the researchers designed a control study in which fluorescein was injected at a point one centimeter away from the Neiguan (PC-6) acupuncture point (a non-acupuncture point injection). This experiment was performed seven times, and none of the experiments generated similar lines.

A total of 28 acupuncture point injection experiments were performed: 23 injections were given at the Neiguan (PC-6) Point, and fluorescent lines appeared 18 times; one injection was given at the Jianshi (PC-5) Point, and a fluorescent line also appeared; and four injections were given at the Daling (PC-7) Points, and fluorescent lines appeared three times.

Overall, 22 of the 28 injections showed lines. Compared with the non-acupuncture point injections, the statistical p-value of the acupuncture point injection experiments was less than 0.001, which means that the existence of the pericardium meridian is clearly possible and not just a figment of the ancients’ imaginations (in general, a p-value of less than 0.05 is statistically significant).

Massaging Acupoints for Palpitations, Insomnia

So, specifically, how does one use the pericardium meridian to treat diseases?

We can perform acupressure: Press each point 100 times, two or three times a day (e.g. once in the morning and once in the evening). You can use your thumb to rub the points directly, or you can use a massage device to produce a slight soreness and swelling at the points. The following are the three major pericardium meridian points to massage.

Neiguan Point (PC-6): Treat Heart Problems, Improve Insomnia

If you have palpitations, irregular heartbeat, a sudden myocardial infarction (heart attack), or other heart problems, massaging the Neiguan (PC-6) Point can help relieve the symptoms.

If someone around you suddenly suffers a heart attack, you should call an ambulance first, then observe the patient’s vital signs and keep communicating with the patient about his or her condition.

If the patient loses consciousness, make sure to clear his or her airway to avoid suffocation. While waiting for an ambulance, press the patient’s Neiguan (PC-6) Points continuously to delay myocardial necrosis to gain some precious time to save the patient’s life.

When using acupuncture, acupuncturists generally consider the direction of the needle: “needling along the direction of meridian Qi-energy flowing (shunjing) is tonifying, and needling against the direction of meridian Qi-energy flowing (nijing) is reducing.”

For instance, if the needle is inserted into the Neiguan (PC-6) Point, it can be inserted in the direction of the palm of the hand (shunjing) to regulate the heart function, or in the direction of the upper arm (nijing), which can also penetrate the Jianshi (PC-5) and Ximen (PC-4) Points to improve angina pectoris (chest pain or pressure) and provide pain relief.

The Neiguan (PC-6) Point is a major point that not only treats heart problems but also improves insomnia.

Quze Point (PC-3): Regulate Heart Function

Quze (PC-3) is the He-Sea point of the pericardium meridian, which means that a lot of energy gathers here, allowing it to regulate the function of the corresponding internal organs. For example, it regulates the function of the pericardium and helps the heart contract. It can be massaged regularly to improve palpitations, chest congestion, and arrhythmias.

Daling Point (PC-7): Relieve Pain, Adjust Mood

The Daling (PC-7) point is a Shu-Stream acupoint of the pericardium meridian and can treat many pains, such as chest and underarm pains, arm pain, and elbow pain. It’s also an acupuncture point that emphasizes reducing, and it can clear heart and liver “fire” energies. Therefore, when you are angry or upset, you can press the Daling Point to relieve your anger.
