A quiet but important point at the very base of the spine. Huiyang (BL-35) gathers and regulates Yang Qi in the lower body — it is a reliable point for haemorrhoidal conditions, disorders of the anus and genitals, and problems of the lower jiao that involve Dampness and Cold.
Contraindications
Standard clean needle technique applies. No specific contraindications are noted in the sources beyond careful and appropriate depth.
Name & story
The name 会阳 Huiyang means "Meeting of Yang" — and that says a great deal about where this point stands in the body. It sits right beside the tip of the coccyx, at the very end of the Bladder Meridian (BL) and just alongside the Governing Vessel (GV), which is the great sea of all Yang in the body. Here, the Yang Qi of the Bladder channel meets and mingles with the Yang of the GV. This junction — this "meeting" — gives the point its name and its particular ability to warm and lift the Yang in the lower body.
Point family & character
BL-35 belongs to the Bladder Meridian (BL). It sits on the posterior portion of the lower trunk, in the region that the Bladder channel covers from the lumbar area downward through the sacrum and coccyx. Points in this part of the channel are classically indicated for disorders of the lumbar region, the anus, the genitals and the lower jiao — intestines, Bladder and uterus.
Five-element dynamics
The Bladder Meridian (BL) is a Water channel, and the lower jiao it governs is the body's deepest reservoir — the place where Jing is stored and where the most fundamental Yin and Yang are held. When Yang Qi fails to warm and move this region, Dampness and Cold settle in, and the tissues of the anus, genitals and perineum suffer. Huiyang (BL-35), as the "Meeting of Yang", draws Yang back into this lowest place, warming it, moving it and lifting what has sunk.
Location
The point is found on the buttocks, beside the tip of the coccyx (tailbone). Locate the very end of the coccyx at the midline and move 0.5 Cun outward on each side — BL-35 sits there, one on each side of the tip of the tailbone.
Needling
The needle is inserted perpendicularly.
Moxa, cupping & Tui Na
Moxa is well suited to this point, particularly when Cold and Yang Deficiency underlie the condition — warming the lower jiao and lifting sunken Yang. Direct warming over the coccygeal area with a moxa stick can complement needling effectively.
Functions
Warms Yang and dispels Cold in the lower jiao. Resolves Dampness and Damp-Heat in the lower body. Regulates the Bladder and intestines. Benefits the anus and genitals. Lifts sunken Yang Qi.
Indications
Haemorrhoids (a classic and primary use). Diarrhoea, including chronic diarrhoea with underlying weakness. Genital disorders: itching, pain or discharge in the genitals. Impotence. Leukorrhoea (vaginal discharge). Pain in the lumbar and sacral region. Disorders of the anus more broadly. Conditions of the lower jiao involving Dampness, Damp-Heat or Cold.
Point combinations
Paired with local points in the sacral and coccygeal region for haemorrhoidal conditions and disorders of the anus. Combined with BL-28 (Pangguangshu) for regulating the lower jiao, Bladder disorders and Dampness in the lower body. Used alongside points that tonify Yang and warm the lower jiao when Cold and Yang Deficiency are at the root.
Clinical spotlight
Huiyang (BL-35) is one of the most consistently cited points for haemorrhoids in classical TCM — its position right beside the coccyx, adjacent to the Governing Vessel, places it anatomically and energetically close to the anus and perineum. Its name — "Meeting of Yang" — reflects its dual role: it both gathers the Yang of the Bladder channel and connects with the GV, making it a point that warms and lifts the lower body when Yang is deficient or Dampness has accumulated. It is a reminder that even small, quietly placed points can hold significant therapeutic power in the right context.
The golden tip
Because of its location near the base of the spine, this point is best left to a qualified practitioner for needling or Moxa. At home, gentle warmth over the lower sacrum and coccyx — such as a warm (not hot) heat pack applied to the area — may offer comfort in conditions of Cold or weakness in the lower body. Always seek professional guidance for haemorrhoidal or pelvic floor concerns.
