The first acupuncture point whose name I learned and was able to identify while my (first) acupuncturist was needling me was “Stomach 36”—”Zu San Li,” or “Three Leg Mile,” in reference to its alleged ability to help the patient walk three additional miles, as all transportation at the time of its discovery was obviously by foot.
“Li,” in Chinese, may also be used as a homonym for “to rectify,” in reference to the energy the point provides, either to our internal physiologies or our kneecaps it resides just inches below. (Yes, this is the point that should feel like a brief surge of shin splint down your tibia)
In modern times we are not as concerned with the need to walk a few extra miles, but the physiological intent holds relevant. Located along the anterior tibial nerve, Stomach 36 can be used to improve energy by its mechanism of increasing blood flow to the stomach, when indicated. That is, if someone is lethargic because they had five drinks the night before and only slept five hours it’s not because their organs are lacking blood. They probably need a different acu-point combination (and a nap).
Besides GERD or acid reflux, Stomach 36 is useful for treating numerous pathologies, including but not limited to diarrhea, bloating, pain of the abdomen, vomiting, belching, also conditions of the throat, chest, and lungs because of the gastrointestinal microbiome’s connection to the respiratory microbiome; finally anxiety, depression, and dizziness, because of the gut brain connection. This 2023 NCBI study concluded its ability to increase the length and mean basal pressure of the lower esophageal sphincter, of which both mechanisms reduce reflux.
According to Peter Deadman’s Manual of Acupuncture, “the great Han dynasty physician (and weren’t all great physicians from the Han??), Hua Tou, is said to have valued the use of ‘ST-36’ to treat the ‘five taxations’ and the ‘seven injuries.’”
The 5 Taxations:
- Excessive use of the eyes injures the blood (even before cell phones—imagine now!)
- Excessive lying down injures the qi (i.e. hypersomnia begets more hypersomnia)
- Excessive sitting injures the flesh (i.e. lack of exercise saps our energy)
- Excessive standing injures the bones (poor security guards)
- Excessive walking injures the sinews (any other New Yorkers remarkably inflexible?!)
Because everything starts and circulates out from the gut, if I had to choose one point to needle on every patient for the rest of my career it would be Zu San Li, Stomach 36. With appropriate metabolic fluids, we can optimize our production of nutrients, which in turn reaches all other systems of the body. Basic science.
