Huantiao Point (GB-30 / Jumping Ring, also known as Huangu, Kuangu, Biyan, Bishu)
Dispels wind-dampness, benefits the lumbar region and legs, and unblocks the meridians. Based on its properties, it is clinically used for sciatica, piriformis syndrome, lumbar pain, post-stroke hemiplegia sequelae, and lower limb numbness.
Indications
Lumbar and hip pain, lower limb paralysis, myositis of the thigh, lumbar sprain, knee and ankle swelling with pain, and hemiplegia. (1) Lower limb flaccidity/bi-syndrome: Post-stroke hemiplegia, limb numbness, knee pain, lumbar pain, sciatica. (2) Male and female reproductive disorders: Orchitis, impotence, leukorrhea, postpartum urinary retention. (3) Skin disorders: Rubella, urticaria, herpes zoster on the thigh.
Precise Location
On the lateral side of the thigh, with the hip flexed in a lateral position, at the junction of the outer 1/3 and middle 1/3 of the line connecting the most prominent point of the greater trochanter of the femur and the sacral hiatus.
Location Method
Stand naturally or lie laterally with the lower leg extended and the upper leg flexed. Place the hand of the same side on the buttock with four fingers in front – the point is where the thumb pad rests.
Massage Method
Press with the thumb pad with moderate force – a sore sensation will occur; firm pressure may cause a numb sensation radiating down the lower limb. Apply for 3–5 minutes per session. Therapeutic actions: Dispels wind and dampness, strengthens the lumbar region and knees, dredges the meridians and unblocks the collaterals.

Efficacy & Actions
Huantiao belongs to the Foot Shaoyang Gallbladder Meridian and is the meeting point of the Gallbladder Meridian and the Foot Taiyang Bladder Meridian. It dredges the meridians and unblocks the collaterals, activates blood and resolves stasis, relieves pain and strengthens the sinews. It is a key point for treating lower limb flaccidity and paralysis, and is one of the Nine Points for Returning Yang, with the ability to revive yang and rescue from collapse. First documented in Zhenjiu Jiayijing. "Huan" means to bend; "Tiao" means to jump. The name refers to the body position for locating the point – bending the body and circling the leg to facilitate jumping – and its ability to treat leg disorders that hinder jumping. It is also known as "Huangu," "Kuangu," "Biyan," and "Bishu." In daily life, we may occasionally strain the lower back, suffer from unbearable lumbar pain, be unable to straighten up, walk hunched over, or lie stiffly in bed unable to move – even a slight turn causes severe pain. In such cases, gentle massage of the tender points on the back and Huantiao can quickly relieve pain. (1) Specific Point for Lower Limb Flaccidity/Bi-Syndrome: Huantiao is widely known for its effects on lumbar and leg pain and is an important point for treating these conditions. The Zhenjiu Jiayijing records: "Acute pain radiating from the lumbar region to the hypochondrium, spasms of the thigh sinews, shin pain with inability to flex and extend, and bi-syndrome with numbness – Huantiao is the primary point." As the meeting point of the Gallbladder and Bladder Meridians – the Bladder Meridian distributes over the back, buttocks, and posterior lower limbs; the Gallbladder Meridian distributes over the lateral body; the sinews of both meridians converge at the ankle, knee, popliteal fossa, buttocks, and sacrum – they treat sinew and bone disorders. Anatomically, the point is located at the sciatic nerve. One point connects two meridians, regulating qi of both Shaoyang and Taiyang to dredge meridians, activate blood, strengthen sinews, and relieve pain. Clinically used for sciatica, lumbar and leg pain, hemiplegia, and various lower limb disorders. The Hongshi Jiyan Fang records: In the year Xin You, Xia Zhonggui suffered from paralysis and could not walk. After prolonged ineffective treatment, Hong Zun needled Huantiao, and the patient could walk immediately. (2) Also Used for Male and Female Reproductive Disorders: Male conditions such as impotence, orchitis, and prostate disorders; female conditions such as urethritis, leukorrhea, and postpartum urinary retention. Needling depth of 2–3 cun is required, directed toward the genital region, with needling sensation transmitted to the genitals for optimal efficacy.
Contraindications
Needling depth should be at least 2 cun; shallower needling may be ineffective. Best results occur when needling sensation radiates to the foot. However, excessive stimulation should be avoided – if an electric shock-like sensation occurs, indicating contact with the sciatic nerve, the needling direction should be changed to prevent nerve injury and lower limb numbness.
