Also known as: Bamboo Spine, Spine Arthritis, Ankylosing spondylitis (acute inflammation), Ankylosing spondylitis (inflammatory phase)
The deep, icy stiffness that eases with a heating pad and the hot, swollen flare that worsens in summer humidity are two entirely different patterns in TCM - and each responds to a different treatment, often bringing noticeable relief within 4 to 8 weeks.

Ankylosing spondylitis isn't a single condition in TCM - it's a family of patterns, each with its own cause and its own treatment. At its root, the Kidneys fail to nourish the spine, leaving it vulnerable to invasion by cold, damp, or heat. The result is the deep stiffness and aching pain that characterize this condition. Below, we explore the two main TCM patterns so you can see which one might match your experience.
Ankylosing spondylitis (AS) is a chronic inflammatory arthritis that primarily affects the spine and sacroiliac joints. It causes pain, stiffness, and over time can lead to fusion of the vertebrae, reducing flexibility.
Symptoms often begin in early adulthood and include morning stiffness that improves with movement, fatigue, and sometimes inflammation in other areas like the eyes or joints. Diagnosis is typically based on symptoms, imaging (X-ray or MRI showing sacroiliitis), and blood tests for the HLA-B27 gene marker.
Conventional treatments
Conventional management focuses on reducing inflammation and maintaining mobility. Nonsteroidal anti-inflammatory drugs (NSAIDs) are first-line for pain and stiffness.
When NSAIDs aren't enough, disease-modifying antirheumatic drugs (DMARDs) like sulfasalazine or biologic agents (TNF inhibitors such as adalimumab, etanercept) are used to slow disease progression. Physical therapy and regular exercise are essential to preserve spinal flexibility. In severe cases, surgery may be considered for joint replacement or spinal correction.
Where conventional treatment falls short
While medications effectively control inflammation and pain, they do not address the underlying constitutional weakness that makes the body susceptible to the disease.
Long-term use of NSAIDs can cause gastrointestinal and kidney issues, and biologics carry risks of infection and immune suppression. Moreover, conventional treatment treats all AS patients similarly, without differentiating between the cold, stiff type of pain and the hot, swollen type - a distinction that in TCM leads to very different treatment strategies.
How TCM understands ankylosing spondylitis
In TCM, the spine is governed by the Kidneys and the Governing Vessel (Du Mai), the channel that runs along the back. The Kidneys store the body's essential energy (Jing) and are responsible for bone health. When Kidney Yang is deficient, the spine lacks warmth and strength, and cold-damp pathogens can easily invade, settling into the joints and causing deep, icy pain and stiffness that worsen with cold and improve with heat.
But not all ankylosing spondylitis is cold. When Kidney Yin is weak, internal damp-heat can brew and then lodge in the spine, producing hot, swollen, heavy joints that flare in humid weather. This pattern often comes with night sweats, a bitter taste, and a red tongue with a greasy yellow coat. The same Western diagnosis thus splits into two fundamentally different TCM patterns - Yang Deficiency with Cold-Damp and Painful Obstruction due to Damp Heat in Channels.
Understanding which pattern dominates is crucial, because treatment for one can worsen the other. A cold pattern needs warming, yang-strengthening herbs and moxibustion, while a heat pattern requires cooling, damp-draining formulas. Your practitioner will use your pain quality, temperature preferences, tongue, and pulse to determine the correct approach.
「足太阳之筋...其病...脊反折，项筋急，肩不举，腋支缺盆中纽痛，不可左右摇。」
"When the sinews of the Foot Taiyang Bladder channel are affected, the spine bends backward, the neck sinews are tight, the shoulders cannot be lifted, there is pain in the armpit and supraclavicular fossa, and the patient cannot turn to the left or right. This description closely matches the spinal stiffness and restricted mobility seen in ankylosing spondylitis."
How a TCM practitioner diagnoses ankylosing spondylitis
Inside the consultation
A TCM practitioner first asks what your stiffness and pain feel like and when they strike. In ankylosing spondylitis (大偻, dà lóu), the spine’s governing meridian is obstructed, and the root is a Kidney deficiency. The crucial fork in the road is whether cold or heat dominates, because that shapes the entire treatment plan.
Pain that is deep, achy, and worse with cold or rest, yet improves with warmth and gentle movement, points to Yang Deficiency with Cold-Damp. You may also feel chilled, with cold hands and feet, fatigue, and a craving for warm drinks. A pale tongue with a thin white coat and a deep, slow pulse confirm this cold pattern.
When the joints feel heavy, swollen, and warm, with a burning sensation, night sweats, and a bitter taste, the picture shifts to Painful Obstruction due to Damp Heat in Channels. The pain is more acute and inflammatory, and damp weather makes the heaviness worse. The tongue is red with a greasy yellow coating, and the pulse is rapid and slippery.
Systemic clues help: cold-pattern patients often have clear urine and a pale face, while heat-pattern patients may have dark, scanty urine and a rapid pulse. By combining your story with tongue and pulse findings, the practitioner identifies which pattern is primary and selects herbs to either warm and disperse or cool and drain.
TCM Patterns for Ankylosing Spondylitis
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same ankylosing spondylitis can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.

Which signs match your experience?
It is completely normal to see a bit of yourself in both patterns. Ankylosing spondylitis often begins as a cold-deficiency condition and can flare into heat during active inflammation. Your body may shift between phases, so don’t worry if your symptoms don’t fit neatly into one box.
To get clearer, focus on the dominant sensation: is your pain more icy and stiff, or hot and swollen? Pay attention to what brings relief - heat or cold applications. Also notice your overall temperature comfort: do you bundle up even when others are warm, or do you feel overheated and sweaty at night? These clues point toward the underlying imbalance.
Self-checking your tongue can be tricky, but a pale, puffy tongue with a thin white coat leans toward cold, while a red tongue with a greasy yellow coat leans toward heat. However, tongue diagnosis takes practice, and you may have a mixed picture. That’s why a professional assessment is so valuable.
If your pain is severe, rapidly worsening, or accompanied by fever, eye inflammation, or unexplained weight loss, see a practitioner promptly. Even for mild symptoms, a TCM practitioner can give you a clear pattern diagnosis and a safe, personalized plan that addresses both the root deficiency and the current obstruction.
Yang Deficiency with Cold-Damp
Treatment
Four ways to address ankylosing spondylitis in TCM — explore each, or take the quiz to see what fits you first.
Formulas traditionally used for ankylosing spondylitis
4 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A classical formula from the Shang Han Lun used to treat lingering cold after a mistaken purgative. It warms the chest, restores depleted Yang, and gently releases lingering Wind-Cold. Patients often present with a feeling of fullness or pressure in the chest, a rapid or irregular pulse, and a slight aversion to cold.
A classical formula for chronic joint and lower back pain caused by long-term exposure to cold and dampness, combined with underlying weakness of the Liver, Kidneys, Qi, and Blood. It works on two fronts: expelling cold, wind, and dampness from the joints and sinews while also strengthening the body's constitution to prevent recurrence. It is especially suited for older adults or anyone whose pain has persisted for a long time and is accompanied by weakness, stiffness, or numbness in the lower body.
A classical four-herb formula used to clear heat and dampness from the lower body. It is commonly applied for hot, swollen, painful joints (especially in the knees and feet), lower limb weakness, and conditions like gout and eczema that involve a combination of inflammation and heavy, waterlogged tissue. The formula works by cooling inflammation, drying excess moisture, strengthening digestion to stop dampness at its source, and directing the formula's effects downward to the legs and lower body.
A classical formula from the Han dynasty used to relieve joint pain, swelling, and stiffness caused by Wind, Cold, and Dampness lodged in the body. It is especially suited for chronic joint conditions where the joints are swollen and painful, the body has become weakened, and the feet are particularly swollen. The formula works by warming the channels, dispelling Wind and Dampness, and protecting the body's fluids from the drying effects of its warming herbs.
Most patients begin to feel a reduction in pain and morning stiffness within 4-8 weeks of weekly acupuncture and daily herbal formulas. Acute inflammatory flares (Damp Heat pattern) may respond more quickly, while the deeper cold-deficiency pattern requires 3-6 months to rebuild Kidney Yang and see lasting change. Long-term management often continues for a year or more to consolidate results and prevent progression.
Treatment principles
Treatment of ankylosing spondylitis in TCM always centers on strengthening the Kidneys and unblocking the Governing Vessel, but the method diverges sharply depending on whether cold or heat dominates.
For Yang Deficiency with Cold-Damp, the strategy is to warm and invigorate Kidney Yang, dispel cold, and dry dampness using formulas like Gui Zhi Qu Shao Yao Jia Fu Zi Tang or Du Huo Ji Sheng Tang, combined with moxibustion on points such as Shenshu BL-23 and Mingmen DU-4.
For Damp Heat in the channels, the focus shifts to clearing heat, draining dampness, and unblocking the collaterals with formulas like Si Miao San or Gui Zhi Shao Yao Zhi Mu Tang, and acupuncture on points like Dazhui DU-14 and Weizhong BL-40.
In practice, many patients present with a mixed picture, and a skilled practitioner adjusts the formula over time as the pattern evolves - for instance, clearing an acute heat flare before addressing the underlying cold deficiency. The goal is always to restore the free flow of Qi and blood along the spine and to rebuild the body's constitutional strength.
What to expect from treatment
Initially, you'll likely have weekly acupuncture sessions and take a custom herbal formula daily. Most people notice a gradual decrease in pain and morning stiffness over the first 4-8 weeks. As symptoms stabilize, sessions may spread to every other week or monthly for maintenance.
Herbal formulas are adjusted periodically based on your progress and any seasonal changes. It's normal to experience occasional flares, but they tend to become shorter and less intense over time. Patience and consistency are key - this is a marathon, not a sprint.
General dietary guidance
For ankylosing spondylitis, a diet that supports the Kidneys and reduces inflammation is ideal. Favor warm, cooked foods like soups, stews, and congees. Include bone broths, dark leafy greens, walnuts, black beans, and small amounts of high-quality protein.
Avoid cold, raw foods, iced drinks, and excessive dairy, which can promote dampness and stiffness. If you tend toward the Damp Heat pattern, also limit alcohol, spicy foods, and fried foods. Ginger and turmeric can be helpful warming, anti-inflammatory additions to meals.
Combining TCM with conventional treatment
TCM can be a valuable complement to your conventional AS treatment. Acupuncture and moxibustion are generally safe alongside NSAIDs and biologics, and many patients use them to manage pain and reduce reliance on medications.
Herbal formulas should be reviewed by both your TCM practitioner and rheumatologist, especially if you are on immunosuppressants, as some herbs may influence liver metabolism or immune function. Always inform all your healthcare providers about every therapy you are using. Do not discontinue any prescribed medication abruptly without consulting your doctor.

Audience-specific guidance — open what applies to you
During pregnancy, the treatment of ankylosing spondylitis requires extra caution. The Yang Deficiency with Cold-Damp pattern remains common, but many warming and blood-moving herbs are contraindicated.
Zhi Fu Zi (Aconite), a key herb for cold-damp Bi, is toxic and strictly avoided during pregnancy. Chuan Niu Xi (Achyranthes) and other herbs that strongly move Blood and descend Qi are also prohibited because they may stimulate uterine contractions.
Du Huo Ji Sheng Tang, while often used for chronic Bi with Kidney deficiency, contains Du Huo and Xi Xin, which are generally avoided in pregnancy. Acupuncture is the preferred modality, but points like Sanyinjiao (SP-6), Hegu (LI-4), and points on the lower abdomen are traditionally avoided.
A gentle approach using moxibustion on Shenshu (BL-23) and Mingmen (DU-4) can safely warm the Kidney Yang without endangering the pregnancy.
During breastfeeding, caution is still needed with potent herbs that may pass into breast milk. Zhi Fu Zi and other toxic or strongly warming herbs should be avoided.
Du Huo Ji Sheng Tang may be used with modifications, but it is wise to consult a TCM practitioner who can adjust the formula. Acupuncture remains a safe and effective option, and gentle moxibustion can help manage pain and stiffness without affecting the infant.
The Damp-Heat pattern may also flare postpartum; in that case, bitter-cold herbs like Huang Bai should be used sparingly to avoid affecting milk supply or causing infant diarrhoea.
Ankylosing spondylitis rarely presents in early childhood, but juvenile-onset AS can occur in adolescents. In TCM, children have immature Kidney Qi, so the pattern is often a more pronounced Kidney essence deficiency with Cold-Damp invasion.
However, treatment must be gentler: herbal dosages are reduced (typically one-half to two-thirds of adult doses), and strong warming herbs like Zhi Fu Zi are used with extreme caution, if at all. Acupuncture needles are thinner and retained for shorter periods. Moxibustion is often well-tolerated and can be a primary therapy. The Damp-Heat pattern is less common in children, but if present, herbs like Cang Zhu and Yi Yi Ren are safe in appropriate doses.
In elderly patients, ankylosing spondylitis often presents as a long-standing condition with advanced joint damage and fusion. The Kidney Yang deficiency is deeper, and Blood Stasis is almost always present due to chronic obstruction.
Treatment focuses on gently warming and nourishing the Kidney and Liver, while invigorating Blood to ease stiffness. Herb dosages should be lower to avoid burdening the digestive system, and formulas like Du Huo Ji Sheng Tang can be modified with added Blood-moving herbs like Dan Shen. Acupuncture should be gentle, avoiding strong stimulation, and moxibustion is highly beneficial. Polypharmacy risks must be considered, as elderly patients often take multiple medications.
Evidence & references
Research on TCM for ankylosing spondylitis has grown, but high-quality evidence remains limited. Several systematic reviews and meta-analyses of acupuncture suggest that it can reduce pain and improve spinal mobility when combined with conventional therapy, though many trials are small and at risk of bias. Chinese herbal medicine, particularly formulas targeting Kidney Yang deficiency and expelling Cold-Damp, has shown promising results in Chinese-language RCTs, with improvements in BASDAI scores and inflammatory markers. However, English-language RCTs are scarce, and the heterogeneity of herbal interventions makes meta-analysis difficult.
Overall, TCM appears to be a safe and potentially effective adjunctive therapy, but larger, well-designed trials are needed to confirm these findings and clarify the optimal treatment protocols.
Key clinical studies
In this 12-week RCT of 120 patients, those receiving modified Du Huo Ji Sheng Tang combined with sulfasalazine showed significantly greater reductions in BASDAI and CRP compared to sulfasalazine alone. The herbal group also reported less morning stiffness and fatigue, with no serious adverse events.

This systematic review included 8 RCTs and concluded that moxibustion, especially when applied to Shenshu (BL-23) and Mingmen (DU-4), provided significant pain relief and improved spinal mobility. The effect was comparable to acupuncture, and no serious adverse events were reported. However, all trials were conducted in China and had methodological limitations.

「肾主腰脚，肾经虚则受风冷，风冷与真气交争，故腰脚疼痛，不能俯仰，久则背偻。」
"The Kidney governs the lower back and legs. When the Kidney channel is deficient, it is invaded by Wind-Cold. The struggle between Wind-Cold and true Qi causes lower back and leg pain, inability to bend forward or backward, and over time, a bent back (hunchback). This ancient text links chronic spinal deformity to Kidney deficiency and external Cold invasion, the same root pathology that TCM identifies in ankylosing spondylitis."

Frequently asked questions
Common questions about using Traditional Chinese Medicine for ankylosing spondylitis.
Yes, many patients find acupuncture provides significant relief, especially for stiffness and localized pain. By inserting fine needles along the spine and related channels, acupuncture helps unblock the flow of Qi and blood, reduce inflammation, and relax tight muscles.
For cold-dominant patterns, moxibustion (warming the points with a burning herb) adds deep warmth that eases the icy ache. Regular sessions are typically needed for sustained benefit.
You may notice some improvement in pain and flexibility within 4-6 weeks of consistent treatment (acupuncture 1-2 times per week plus daily herbs). However, ankylosing spondylitis is a chronic condition, and rebuilding the underlying Kidney deficiency takes time - often 6 months to a year for significant, lasting change. The goal is gradual reduction of flare frequency and intensity, not an overnight cure.
In most cases, TCM herbs can be used alongside conventional medications, but it is essential that both your rheumatologist and TCM practitioner are aware of everything you are taking. Some herbs may affect liver function or interact with immunosuppressants.
We recommend bringing a full list of your medications to your TCM consultation so your formula can be tailored safely. Never stop or adjust your prescribed medication without medical supervision.
Diet plays a supportive role. Generally, we advise avoiding cold, raw foods and icy drinks, which can worsen cold-damp patterns.
For those with damp-heat, greasy, spicy, and overly rich foods may aggravate inflammation. A warm, cooked, easily digestible diet with plenty of vegetables, lean proteins, and anti-inflammatory spices like turmeric can benefit most people with AS. Your practitioner may give more specific guidance based on your pattern.
TCM does not claim to 'cure' AS in the sense of erasing the disease, but it aims to bring it into long-term remission by correcting the internal imbalances that allow it to progress. Many patients experience greatly reduced pain, improved mobility, and fewer flares, allowing them to maintain an active life. The focus is on managing the condition and preventing spinal fusion, not on a quick fix.
In TCM, the tongue is a map of the body's internal condition. A pale, puffy tongue with a white coating suggests cold and deficiency, pointing to the Yang Deficiency pattern.
A red tongue with a greasy yellow coating indicates heat and dampness, signaling the Damp Heat pattern. Your practitioner uses this, along with your pulse and symptoms, to confirm which pattern is driving your ankylosing spondylitis.
