Tai Chong (LV3) is commonly used for stress, lower back pain, high blood pressure, menstrual cramps, limb pain, insomnia and anxiety. Tai Chong (LV3) is located on your foot about two finger widths above the place where the skin of your big toe and the next toe join. To use acupressure on this point, (1) locate the point with your shoes off then (2) use deep, firm pressure to massage and stimulate the area for 4-5 seconds.

The point is located between the big toe and the second toe.

Slide your finger along the space between the first and second toe to the tip of the joint.The point is located in the depression before your finger touches the bone (metatarsal joint).

Apply pressure and massage for 2-3 seconds.
Its additional indications as stated in the ancient Chinese text include digestive issues, eye problems, genital pain, headaches, canker sores, and irritability.
In the scientific literature, a randomized trial has yielded a positive result with acupuncture stimulation on Tai Chong (LV3) and other points to manage post-stroke depression [1]. Animal studies have also shown that Tai Chong (LV3) lowers blood pressure and plasma endothelin-1 levels in hypertension subjects [2].
