Combined with other self-care, stimulating the Fu Tu acupoint supports thyroid health.
Before iodine was added to table salt, thyroid issues were common, and doctors frequently treated goiter, the swelling of the thyroid glands. In countries where iodine deficiency has been addressed, this form of goiter is now rare. However, thyroid problems persist.
People with obesity, insulin resistance, and metabolic syndrome are considered to be at higher risk. Women are approximately four times more likely than men to develop goiter. If you’re looking for an additional way to support your thyroid health, consider the acupoint Support the Prominence (Fu Tu, LI18). As with many aspects of holistic systems, Fu Tu offers multiple benefits.
How Fu Tu Aligns With Classical TCM
Fu Tu was first mentioned in the “Ling Shu” (“Spiritual Pivot”). It is located on the Large Intestine meridian, which travels from the tip of the index finger, up the arm, along the throat, and into the head. This meridian or energy pathway is rich in qi and blood, two inseparable forms of energy, and is said to deliver this energy from the lower parts of the meridian to the organs in the area of the head. Like many acupoints, Fu Tu is used to treat the area where it is located.Fu Tu was commonly used for goiter in the past and remains in clinical use today for goiter caused by thyroid gland malfunction. It is said to be effective by helping to normalize the flow of energy in the region. Its location along the throat and connection to facial organs also allow it to address symptoms such as cough, swollen throat, hoarseness, or sudden loss of voice. People who speak frequently or sing may benefit from Fu Tu.
Evidence From Animal Research
As research into acupuncture expands, scientists are uncovering the biological mechanisms that make acupoints effective. One study investigated the effects of electroacupuncture on pain and gene expression related to GABA, an inhibitory neurotransmitter, in rats with thyroid-area inflammatory pain. Pain was induced with formalin, and three acupoint sets were tested: Fu Tu (LI18), Hegu–Neiguan (LI4–PC6), and Zusanli-Yanglingquan (ST36-GB34).Rats treated at the first two sets showed reduced pain behavior, higher tolerance to heat pain, and fewer inflammatory cells in the thyroid tissue. Those two groups also had higher expression of GABA-related genes in the cervical spinal cord. The study suggests that electroacupuncture protocols, including Fu Tu, reduce thyroid-related pain by boosting GABA receptor activity and reducing inflammation.
Another study examined how LI4 (Hegu), PC6 (Neiguan), and LI18 (Fu Tu) are connected to the thyroid gland in rats. Researchers used fluorescent dyes to trace nerve connections. They found that the acupoints and the thyroid shared common sensory nerve cells in the clusters of nerve cell bodies in the neck that relay sensory information to the spinal cord, mainly in the third to seventh cervical vertebrae. This overlap indicates that nerve pathways from these acupoints also reach the thyroid region.
How to Locate and Stimulate Fu Tu
Find your sternocleidomastoid muscles—the thick, prominent muscles on both sides of the Adam’s apple that bulge when you turn your head to the side. Fu Tu is located level with the tip of the Adam’s apple, between the two heads of the muscle. Feel around this area for a spot that is sore or tender to the touch. These sensations indicate the presence of an acupoint.Ways to Stimulate Fu Tu
- Firm pressure: Press firmly for three to five seconds, then relax for three seconds. Repeat for one to three minutes on each side.
- Circular massage: Massage in small circles with your index finger or thumb for one to three minutes on each side.
- Herbal patch: Apply an herbal patch overnight for longer activation.
- Advanced methods: Acupuncture or moxibustion, a gentle heat therapy using dried mugwort, by a trained professional, can deepen the therapeutic effects.
Precautions
Avoid using this acupoint if there are injuries in the area. When using herbal patches, opt for products without harsh or artificial ingredients, especially if you have sensitive skin.Reinforcing Your Thyroid Health Routine
Eating a balanced diet rich in iodine is an important way to support thyroid function. However, the body is influenced by numerous factors, and it often requires more than one approach to achieve a healthy balance. If you’re seeking extra support for your thyroid, consider using acupressure at Fu Tu. It’s free, easily accessible, and only takes a few mindful minutes—without any added cost or need for a doctor’s visit.
