What Huantiao does
Huantiao is treated here as a practical point rather than a curiosity: where it sits, how it is needled, what the tradition says it does, and the skin conditions in this database that name it.
Actions
- Removes Obstructions from the Channel
- Resolves Dampness and expels Wind
Location
The written location is summarised from the classical record; use the landmark named there together with the diagram.
How to find it
Find the bony landmark first, then feel for the hollow or tender spot the location describes. The point is usually sensitive when pressed. Place the patient on the side being treated, with the upper thigh drawn up towards the abdomen and the lower leg left straight; the reference insists on this position because the point cannot be judged properly from a prone patient. Find the sacral hiatus, the small gap at the lower end of the sacrum that the texts call Yaoshu DU-2, and then the most lateral point of the greater trochanter. Draw an imaginary line between the two and divide it into thirds. Huantiao lies at the junction of the middle and outer thirds, one third of the way from the trochanter towards the sacrum, where the muscle gives under pressure and the point is tender.
Deqi
De qi at this point is felt as local distension, heaviness or aching, and may travel a short way along the channel.
A cun is a proportional body measurement, not a fixed length: one cun is about the width of the thumb at the knuckle, 1.5 cun about two finger widths, and 3 cun about the width of four fingers. On an average adult one cun is roughly one inch, but it scales with the person, which is why the texts measure in cun rather than centimetres.
Technique
Needling
Angle: 90 degrees, perpendicular Depth: Standard depth two to three cun. Direction: Needle in the direction the location describes.
Moxibustion
The classical records 10 to 20 minutes of moxibustion at this point. Warmth suits the cold and damp version of the hip picture, where the pain is fixed, worse in cold weather and eased by heat, and it is the gentler option for a depleted patient who cannot take strong needling. It is also the practical choice when the point is too tender for a deep needle.
Gua sha
The reference marks gua sha at Huantiao as questionable, so it is neither recommended nor ruled out. Two things argue for care. The sciatic nerve lies directly beneath the point, and pressure work over a nerve is not the same as pressure over muscle. The point also sits in thick gluteal muscle that surface scraping barely reaches, so the reference does not treat gua sha as a way of influencing it. Where it is used at all it belongs on the surrounding buttock rather than on the point itself.

Combinations
Wind rash and itchy skin: Huantiao with Fengchi and Quchi
GB-30 Huantiao, GB-20 Fengchi, LI-11 Quchi
This is the skin combination in the reference, given for generalised urticaria, eczema and itching driven by external Wind. Quchi clears Heat from the surface, Fengchi releases Wind at the neck, and Huantiao brings the same clearing action from the hip. The reference uses the trio where the rash moves about and the itching is worse for heat or for draught, which is the pattern it treats as Wind rather than as Damp.
Classical record
Pain of the lumbar region and lateral costal region pulling and acute, spasm of the thigh sinews, pain of the lower leg that cannot be extended or flexed, painful obstruction with loss of sensation - Huantiao governs these.
Classical citation for this point.
Treats cold Wind-Damp painful obstruction, wind rash, unilateral Wind with hemiplegia, pain of the lumbar region and hip preventing turning to either side.
Classical citation for this point.
Huantiao lies in the hip joint and rules Cold, Wind and Damp painful obstruction; the pain runs from the hip into the calf and the patient sighs at every attempt to turn over; needle two cun, wait for the arrival of Qi, and the cure follows.

Safety
Who should treat this point
Acupuncture and moxibustion are practitioner procedures. This page is educational and is not a guide to self-treatment.
Caution
Safety flags: the reference marks it as a dangerous point. Needle with care, adjust depth to the patient's build, and modify or avoid the point where a flag applies. The sciatic nerve runs directly beneath this point, so the reference warns against forceful or repeated lifting and thrusting once the needle is in place; a gentle rotation or a still needle is safer than a pumping action. If the patient reports a sharp electric current the needle has met the nerve, and it should be withdrawn a little before the position is adjusted. Long needles of 3 to 4 inches, that is 75 to 100 mm, are needed for a well-muscled hip, while a thin patient needs a shorter shaft and a shallower target. Depth is judged by build rather than by a fixed number, and the point should not be attempted on anyone who cannot hold the lateral position.
Deficiency and constitution
In a depleted patient the point is worked gently and briefly.
Before treatment
Educational reference only. Skin that is spreading, painful, blistering or accompanied by fever needs medical assessment.

Evidence note
No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
Common questions
What does Huantiao do in skin practice?
It is used where the skin picture includes eczema fatigue hip pain sciatica urticaria hemiplegia itchy anus urethritis leg atrophy itchy groin wind-stroke leg numbness loose stools buttocks pain poor appetite outer leg pain knee stiffness blurred vision vaginal discharge, always as part of a combination chosen for the pattern.
Why does needling Huantiao sometimes send a current to the foot?
The point lies over the sciatic nerve, and a needle that reaches the nerve produces the electric, numb quality the tradition describes travelling down the back or the side of the thigh, through the knee, into the calf and the toes. In sciatic cases this response is expected and useful, but the reference warns that the needle should be eased back if it feels sharp or violent, and that lifting and thrusting should be avoided at that depth.
How deep is Huantiao needled, and with what needle?
The reference asks for at least 2 inches, about 5 cm, for the local effect, and notes that a well muscled patient may need a 3 to 4 inch needle, which is 75 to 100 mm. The angle is perpendicular, or oblique at about 45 degrees for a different target. Depth is judged by the build of the patient and by the response obtained rather than by a fixed figure, and the needle is not driven in further in the hope of a stronger effect.
Which skin conditions name Huantiao?
Urticaria and eczema are the two the reference gives, both understood as Wind and Damp lodged in the channels. The point is also recorded for damp heat in the Lower Burner, which brings an itchy anus or groin, vaginal discharge and urethritis. On this page the skin uses are always part of a combination chosen for the pattern rather than a stand-alone treatment for a rash.
