GB30 (Huantiao, “Huantiao”) is the Meeting point of GB & UB point of the Gallbladder Channel Meridian. It is located on the postero-lateral aspect of the hip, in a depression located at the junction of the lateral one-third and medial two-thirds of the distance between the prominence of the greater trochanter and the sacral hiatus. The point is most easily found with the patient in a side-lying position with the upper leg flexed at the hip and the lower leg extended. It expels wind, dampness, and cold from the channel; strengthens the lower back and legs; unblocks the channel and alleviates pain; treats disorders of the hip and lower limb.

Location

On the postero-lateral aspect of the hip, in a depression located at the junction of the lateral one-third and medial two-thirds of the distance between the prominence of the greater trochanter and the sacral hiatus. The point is most easily found with the patient in a side-lying position with the upper leg flexed at the hip and the lower leg extended.

Needling

Perpendicular insertion, 2.0 to 3.5 cun deep, directed towards the genitals. Deep needling may elicit a sensation that radiates down the leg, indicating proximity to the sciatic nerve.

Meeting point of GB & UB

Clinical notes

Huantiao is a primary and indispensable point for treating disorders of the hip, buttock, and leg, especially sciatica and pain radiating along the Gallbladder channel. Its ability to expel wind-damp makes it effective for bi-syndrome affecting the lower body, hemiplegia, and post-stroke paralysis. The classical texts repeatedly emphasize its use for restoring mobility, treating pain that makes it difficult to stand, walk, or turn. It is also noted for treating wind rash, demonstrating its function in expelling wind from the entire body.
