Over on my HinesSight blog yesterday, I posted "Some life lessons from a Tai Chi seminar."
These were some of the insights I got from a special three-hour class my Tai Chi instructor, Warren, put on for five students who are especially interested in the martial side of Tai Chi, as contrasted with the energetic/exercise side.
During the seminar Warren, who used to teach classes in East-West Medicine at a nearby college, talked about the meridians that are part of Chinese medicine. This is how a Wikipedia article about meridians starts off.
The meridian system (simplified Chinese: 经络; traditional Chinese: 經絡; pinyin: jīngluò, also called channel network) is a pseudoscientific concept from traditional Chinese medicine (TCM) that alleges meridians are paths through which the life-energy known as "qi" (ch'i) flows.
Meridians are not real anatomical structures: scientists have found no evidence that supports their existence. One historian of medicine in China says that the term is "completely unsuitable and misguided, but nonetheless it has become a standard translation." Major proponents of their existence have not come to any consensus as to how they might work or be tested in a scientific context.
I'd heard Warren describe meridians several times before. He knows their names and where they supposedly are in the human body. But I don't recall him ever talking about how someone can prove that they exist, or why they're relevant to Tai Chi practice.
From what I can tell, Tai Chi supposedly facilitates the movement of qi/chi in the body, as this web site says.
Tai Chi and Qigong, when taught as mindfulness relaxation therapies can help clear tension blocks, which facilitates a natural healthful flow of Qi or life energy, as well as blood and lymph circulation. Chinese Acupuncture involves 12 Main Meridians, such as the "liver meridian" the "lung meridian" the "kidney meridian" so the gentle massaging of the body, which sets Tai Chi and Qigong apart from other exercises, results also in "massaging the internal organs" and supporting their function and the flow of Qi, or life energy.
The problem I have with meridians is basically the same problem I have with any form of unproven supernatural belief. I include meridians in the broad category of supernatural belief because while life and energy obviously are real, "life energy" in the sense of qi isn't.
Here's part of what the Science-Based Medicine web site says about Chinese medicine:
One of the themes of science-based medicine is to be suspicious of any form of medicine that is not science-based. In other words, beware of dodgy qualifiers placed before “medicine,” such as: “alternative”, “integrative”, or “complementary” – those that imply that something other than science or evidence is being used to determine which treatments are safe and effective.
I would also include “traditional Chinese” medicine in the dodgy category. A recent article defending Traditional Chinese Medicine (TCM) provides, ironically, an excellent argument for the rejection of TCM as a valid form of medicine. The authors, Jingqing Hua and Baoyan Liub, engage in a number of logical fallacies that are worth exploring.
...There is no evidence that the meridians actually exist. At the risk of sounding redundant, they are as made up and fictional as the ether, flogistum, Bigfoot, and unicorns. The linking of qi and blood is reflective of the fact that the notion of qi is historically tied to blood, and techniques such as acupuncture and cupping were also closely related to bleeding techniques that we are more familiar with from Galenic medicine.
Here's the thing. If meridians exist, seemingly they would have some effects in the human body. Those effects should be evident through scientific experimentation. Or some other means. But I couldn't find convincing evidence of this sort.
You may be thinking, what about acupuncture? Well, acupuncture has been found to relieve some types of pain about as well as over-the-counter medications like Tylenol. But there isn't a lot of evidence for the general effectiveness of acupuncture, according to a Scientific American story, "Research Casts Doubt on the Value of Acupuncture."
Studies have found no meaningful difference between acupuncture and a wide range of sham treatments. Whether investigators penetrate the skin or not, use needles or toothpicks, target the particular locations on the body cited by acupuncturists or random ones, the same proportion of patients experience more or less the same degree of pain relief (the most common condition for which acupuncture is administered and the most well researched). “We have no evidence that [acupuncture] is anything more than theatrical placebo,” says Harriet Hall, a retired family physician and U.S. Air Force flight surgeon who has studied, and long been a critic of, alternative medicine.
I've had about a dozen acupuncture treatments for sciatica pain in my right leg. After the first couple of treatments, my pain was much better. However, I have no idea if acupuncture was the cause. The way I express this to my acupuncturist is "I'm not sure if I believe in acupuncture, but I definitely believe in the placebo effect."
She's fine with my attitude, as she never mentions anything associated with Chinese medicine, including meridians. She knows that acupuncture benefits her clients. If that benefit is partly or wholly because of the placebo effect, great. Whatever works. So I keep going for more treatments. Have one tomorrow, in fact. (I wrote about my acupuncture treatments in "I benefitted from my sessions at Salem's Innerhealth Acupuncture Clinic.")
I feel the same way about meridians. My Tai Chi instructor clearly believes in them. I have no problem with that, just as I have no problem with some people in my class being religious. Whatever works for them. If I'm asked whether I believe in meridians or qi or God, I'll answer "No." However, I understand why others believe in entities for which there is no demonstrable evidence. I used to be such a believer myself.
It's only when someone claims that their faith-based belief is true, and expects me to share that belief, that I'll defend my skepticism. Meridians seems to be an example of an unfounded belief that rarely causes harm, though if someone chooses Chinese medicine to cure an aggressive cancer, they definitely are putting themselves at great risk.
