Definition

Rheumatoid arthritis (RA) is a chronic systemic autoimmune and inflammatory disease that begins in the synovium and destroys cartilage and bone. Modern medicine focuses on the overreaction of immune cells and cytokines, while Korean Medicine views it as 'Bi-jeung (痺證, Bi syndrome)' or 'Yeokjeolpung (歷節風),' a state where the circulation of Qi and Blood (氣血) is blocked and Vital Qi (正氣) is weakened, allowing pathogenic factors (邪氣) such as Wind, Cold, Dampness, and Heat (風寒濕熱) to reside in the joints. It is an explanation of the same clinical phenomenon using different terminologies.

RA is not merely a disease of joint pain, but a condition where the malfunction of the immune system and the collapse of the balance of Qi, Blood, Nutritive Qi, and Defensive Qi (營衛) throughout the body progress together. While modern medicine excels at suppressing evidence of inflammation, Korean Medicine tracks why that inflammation recurs and why it persists in a specific individual through pattern identification (辨證). The approach of extinguishing symptoms and the approach of restoring Vital Qi to allow the body to cease inflammation on its own have different objectives. Baengnokdam Oriental Medical Clinic's integrative medicine utilizes these two perspectives simultaneously.

What Patients Actually Experience

Some people wake up in the morning with fingers so stiff that even turning off a smartphone alarm is a struggle. Being diagnosed with rheumatoid arthritis at a young age and seeing only "a cure is impossible" online can cause one's spirit to break first. Joints tingle while typing on a keyboard, and hands go numb even during meetings. Test results show that CRP or ESR levels decrease to some extent with medication, but morning stiffness and fatigue still persist.

When the rainy season or winter approaches, some say, "My joints know exactly when the weather is bad." Body aches with throbbing and numbing joint pain throughout the body can last for days, and many feel their stomach is weakened due to long-term medication. Even when blood tests show inflammatory markers are within the normal range, the body still feels heavy and tired.

Those who cannot rest because of their livelihood face different challenges. A restaurant owner may find it difficult to lift heavy objects due to wrist and ankle pain, and because the job requires standing all day, inflammatory markers do not easily decrease. Behind the words, "What do I do if I can't use my hands when I have to work right now?" lies the reality of not even having enough time for treatment.

Others already have joint deformities, making fine motor skills like buttoning a shirt or holding chopsticks impossible. With blurry vision and bent joints, it is not just the pain; daily life itself is a struggle. As the number of medications increases due to various comorbidities, concerns about drug interactions grow: "Is this medicine okay to take with that one?"

The questions these patients commonly ask are similar: "Why is it so hard when my tests are normal?" Modern medical tests primarily show inflammatory markers, antibodies, and imaging findings. However, the body's center of gravity, morning stiffness, the depth of fatigue, pain fluctuations according to the weather, digestive status, and sleep quality are not well-captured by numerical values. Traditional Korean Medicine views this point as 'Residual Pattern Identification (殘存 辨證).' The fire of inflammation has been extinguished for now, but the flow of Qi and Blood (氣血) is still blocked, and the body's defense and nutritional circulation, known as Ying and Wei (營衛), has not recovered. In other words, the traces of the illness remain, and these traces manifest as pain, fatigue, stiffness, and sensitivity to weather.

Furthermore, RA is not just a problem of the joints. Chronic inflammation leads to shallow sleep and deepens feelings of depression and fatigue. When intestinal function slows down, the balance of the immune system can be disrupted. What the patient experiences is not just a single symptom called "joint pain," but a holistic experience that simultaneously threatens their sense of time in daily life, their ability to work, the fear of becoming a burden to their family, and the quality of their remaining life.

The Lens of Modern Medicine

Rheumatoid arthritis (RA) is a systemic autoimmune disease in which chronic inflammation originating in the synovium destroys cartilage and bone. Modern medicine explains this as an overreaction of immune cells and cytokines, and sets the early suppression of disease activity as its core goal.

At the center of the pathophysiology is the excessive secretion of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6. These stimulate synovial cells to cause synovial hypertrophy and angiogenesis, and eventually, an infiltrating tissue called pannus erodes the cartilage and bone. Simultaneously, Th17/Treg imbalance, B-cell autoantibody production (RF, anti-CCP), and RANKL-mediated osteoclast activation accelerate joint destruction. Understanding these mechanisms is necessary to answer the patient's question: "Why do my joints continue to deteriorate even though my inflammation levels have decreased?" This is because even if levels are normal, microscopic angiogenesis or residual inflammation can still damage the tissue.

Diagnosis refers to the 2010 ACR/EULAR RA classification criteria. Scoring is based on the site and number of joint involvements, serological findings (RF, anti-CCP), acute phase reactants (CRP, ESR), and duration of symptoms. For early diagnosis, the use of joint ultrasound or MRI, in addition to X-rays, is increasing. NICE guidelines recommend urgent referral to a rheumatologist for small joint involvement, polyarticular symptoms, or delays of more than 3 months. In other words, in RA, time is joints. The first 3 to 6 months is the "golden window" for treatment; if DMARDs are not started during this period, joint damage may progress to an irreversible stage.

Standard treatment consists of three main branches. First, csDMARDs, with methotrexate (MTX) as the first-line agent, often used in combination with sulfasalazine, leflunomide, or hydroxychloroquine. Second, bDMARDs, which include TNF inhibitors (etanercept, adalimumab, etc.), IL-6 receptor antagonists (tocilizumab), CTLA-4-Ig (abatacept), and CD20 antibodies (rituximab). Third, tsDMARDs, such as JAK inhibitors (tofacitinib, baricitinib, etc.). The treatment strategy is Treat-to-Target (T2T), which involves repeated regular monitoring and adjustments with the goal of achieving clinical remission or low disease activity (LDA).

This modern medical approach has significantly changed the natural course of RA. However, clear limitations and unmet needs still exist. The first that comes to mind is refractory RA, or Difficult-to-Treat RA (D2T). There is a group of patients who fail to reach the target remission despite receiving guideline-based treatment, which involves multidimensional factors such as chronic pain syndrome, comorbidities, psychosocial distress, and treatment adherence, rather than just simple drug resistance. It should also be noted that unnecessary treatment escalation can actually worsen the long-term prognosis.

Second, there is a discrepancy in response to biological agents. Approximately 40% of RA patients do not respond to individual biological agents, which is why modern medicine is attempting a "precision medicine" approach. In the STRAP trial and R4RA trial, research is underway to predict responses to etanercept, tocilizumab, and rituximab using RNA-seq-based biomarkers of synovial tissue. This demonstrates the fact that "even with the same RA, the nature of inflammation differs from person to person."

Third, there are issues with side effects, cost, and quality of life. Biologics and tsDMARDs are associated with risks of infection, potential malignancy, hepatic, renal, and cardiovascular side effects, and high costs. In a domestic cohort study, the quality of life score for RA patients (0.68) was found to be lower than that of cancer patients (0.75). Symptoms such as pain, fatigue, sleep disorders, depression, and functional decline are often difficult to capture through blood tests or imaging. In particular, the answer to "Why is it so hard when the tests are normal?" may be incomplete with modern medicine alone.

This is where integrative medicine, especially Korean Medicine, can play a complementary role. While modern medicine turns off the mechanical switch of inflammation and prevents joint damage, Korean Medicine focuses on why that switch keeps trying to turn on, finding the cause in the balance of the whole body's immunity, Qi and Blood, and Ying and Wei, and restoring the individual's state. This involves using two lenses simultaneously: symptom suppression and fundamental recovery.

In the next step, we will look at RA again through the lens of pattern identification (辨證) in Korean Medicine and examine how it maps to modern phenotypes and mechanisms.

The Lens of Traditional Korean Medicine

In Traditional Korean Medicine (TKM), Rheumatoid Arthritis (RA) is interpreted as Bi-jeung (痺證, Bi syndrome) or Yeokjeolpung (歷節風). 'Bi' (痺) signifies a state of obstruction, where Qi and Blood (Gihyeol) cannot flow smoothly through the joints and meridians, leading to pain, stiffness, and edema. While modern medicine focuses on synovial inflammation and immune cells, TKM pays attention to the "bodily foundation" where that inflammation occurs—the deficiency or excess of Zheng Qi (Vital Qi) and the flow of Qi, Blood, and Ying-Wei (Nutritive and Defensive Qi). These are different languages describing the same disease, and using both lenses brings us closer to addressing residual symptoms and achieving holistic recovery for the patient.

The core pathogenesis involves the invasion of Wind, Cold, Dampness, and Heat (pathogenic factors) into a state of Zheng Qi deficiency, leading to the formation of Phlegm-fluid (Dameum) and Blood Stasis (Eohyeol). In the early stages, external pathogens block the meridians, causing pain. As the condition becomes chronic, the depletion of Qi and Blood and the deficiency of the Liver and Kidney (Gansin) reduce the nutrient supply to cartilage and bone, leading to progressive deformity. This progression corresponds to the pathophysiology of modern medicine. Cytokine storms and angiogenesis can be understood in the context of 'Dampness, Heat, and Blood Stasis,' while chronic synovial hypertrophy and bone destruction align with 'Stagnation of Phlegm and Blood Stasis' (Damhyeol-eoche) and 'Liver and Kidney Deficiency' (Gansin-bujok).

Connecting the pattern identification (Byeonjeung) types with modern phenotypes is as follows:

Wind-Cold-Dampness Bi (風寒濕痺) is a type where pain shifts locations, worsens with cold and humidity, and is characterized by prominent morning stiffness. Modernly, this often corresponds to early RA, low disease activity states, or cases with low-level cytokine activity. 'Wind' (風) corresponds to the mobility of pain and paresthesia, 'Cold' (寒) to muscle and vascular constriction, and 'Dampness' (濕) to edema and mucinous synovial inflammation. Treatment focuses on expelling Wind, Cold, and Dampness and promoting the flow of Qi and Blood, using formulas such as Duhuo Jisheng Tang (獨活寄生湯), Gegen Tang (葛根湯), and Mahuang-ga-zhu-tang (麻黃加朮湯). The "Korean Medicine Clinical Practice Guideline for Rheumatoid Arthritis," developed in 2024, provides GRADE-based recommendations for acupuncture, moxibustion, herbal medicine, pharmacopuncture, acupotomy, and thread embedding. Herbal medicine received a Grade B recommendation, stating it "should be considered" both as a monotherapy and in combination with conventional medicine (NCKM, 2024).

Wind-Dampness-Heat Bi (風濕熱痺) corresponds to the acute inflammatory phase where joints are red, hot, swollen, and severely painful. Modernly, this phenotype is characterized by high disease activity, elevated acute-phase reactants, and polyarthritis. 'Heat' (熱) corresponds to the excess of pro-inflammatory cytokines such as IL-6 and TNF-α and synovial angiogenesis. Formulas like Baihu Jia Zhu Tang (白虎加朮湯) and Danggui Niantong Tang (當歸拈痛湯) are used to clear heat and remove dampness. At this stage, while modern DMARDs and biological agents rapidly suppress disease activity, TKM can play a complementary role by managing the systemic foundation of Heat and Dampness.

Stagnation of Phlegm and Blood Stasis (痰瘀血滯) is the chronic phase. Pain becomes fixed, and hard nodules or deformities appear around the joints. Modernly, this is the stage where long-term synovial hypertrophy, pannus formation, and cartilage/bone destruction have progressed. 'Phlegm' (痰) can be likened to mucus and fibrotic tissue formed by chronic inflammation, and 'Blood Stasis' (瘀血) to microcirculatory disorders, angiogenesis, and fibrosis. Formulas such as Shenqi Wan (腎氣丸) and Huoxue Siwu Tang (活血四物湯) are used to resolve phlegm and activate blood. Mechanisms have been reported where acupuncture therapy inhibits synovial angiogenesis by reducing VEGF and VCAM-1 and decreases osteoclastogenesis by reducing RANKL (Am J Chin Med, 2026).

Deficiency of both Qi and Blood (氣血兩虛) is characterized by chronic fatigue, anemia, anorexia, and decreased muscle strength. This corresponds to RA accompanied by systemic weakness, decreased immunity, and anemia due to long-term medication or inflammatory consumption. Formulas like Shijuan Dabo Tang (十全大補湯), Buzhong Yiqi Tang (補中益氣湯), and Guizhi Shaoyao Zhimu Tang (桂枝芍藥知母湯) are used to replenish Qi and Blood and harmonize Ying-Wei. Modern research has shown that acupuncture therapy improves immune and metabolic functions by restoring the Treg/Th17 balance, regulating the M1/M2 macrophage balance, and activating antioxidant pathways (Keap1-Nrf2/ARE/HO-1) (Medicine, 2024; Chin Med, 2025).

Liver and Kidney Deficiency (肝腎不足) is the phase where the disease enters its later stages, accompanied by joint deformity, osteoporosis, sarcopenia, and dry eyes. According to TKM theory, where the Liver (肝) governs fascia and ligaments and the Kidney (腎) governs bone and marrow, this explains the decline in nutrient supply and regenerative capacity of bone and cartilage. Formulas such as Duhuo Jisheng Tang (獨活寄生湯), Sijunzi Tang (四君子湯), and Da Fangfeng Tang (大防風湯) are used. At this stage, holistic management, including functional recovery, fall prevention, and management of dry mouth and eyes, is important.

Modern evidence for TKM treatment is gradually accumulating. In a 2022 meta-analysis (Li et al., 11 RCTs), acupuncture significantly improved VAS pain, TJC, SJC, CRP, RF, and ESR in RA patients, with superior effects when combined with conventional medicine (Evid Based Complement Alternat Med, 2022). In a network meta-analysis the same year (32 RCTs, 2,115 patients), acupuncture combined with conventional medicine showed superior effects on ACR20/50/70 and inflammatory indices (Front Immunol, 2022). A meta-analysis on moxibustion therapy also showed that conventional medicine plus moxibustion had an effect of RR 1.57 in ACR50 (Moxibustion for RA, 2014). These results suggest that TKM treatment does not simply "relieve pain" but can intervene in multiple axes of inflammation, immunity, and pain regulation.

When approaching Rheumatoid Arthritis at Baengnokdam Korean Medicine Clinic, we first identify the individual's disease stage through pattern identification. Even for the same RA, the prescription and acupuncture strategy vary depending on the patient's constitution, disease progression, accompanying symptoms, and current medications. For young, early-stage patients, emphasis is placed on Wind-Cold-Dampness Bi or Wind-Dampness-Heat Bi. For patients whose gastrointestinal tract, Qi, and Blood have been damaged by long-term medication, we supplement Qi and Blood. For patients with progressed deformity, we address both Stagnation of Phlegm and Blood Stasis and Liver and Kidney Deficiency. While modern DMARDs and biological agents suppress disease activity, TKM is used in parallel to restore the underlying Qi, Blood, Ying-Wei, and Zheng Qi. This is an integrative medical approach that goes beyond symptom suppression to enhance the body's self-healing power.

Integration — Where Two Lenses Meet

Where the two lenses meet, RA is no longer seen merely as a "disease where inflammation must be suppressed," but as a multidimensional state involving immune system imbalance, blockage of Qi and Blood circulation, the gut-joint axis, and psychosomatic stress. Modern medicine and Traditional Korean Medicine (TKM) explain the same clinical phenomena in different languages; when both languages are used simultaneously, the status of each individual patient can be read more precisely.

Table 1. Mapping Modern Mechanisms/Phenotypes to TKM Pattern Identification Units

Integrated Interpretation of the Gap: "Why do I suffer when tests are normal?"

This is one of the most common conflicts in RA treatment. ESR and CRP have normalized, and inflammation has decreased on ultrasound, yet morning stiffness, fatigue, numbness in hands and feet, sleep disorders, and decreased concentration persist. Modern medicine explains this as "fibromyalgia-like symptoms," "central sensitization," "chronic pain syndrome," or "poor treatment response." TKM reads this as Residual Pattern Identification (殘存辨證).

• Qi and Blood Deficiency (氣血兩虛): Energy and nutritional status exhausted by long-term inflammation and drug use. Fatigue, anemia, decreased muscle strength, and delayed recovery.
• Disharmony between Ying and Wei (營衛不和): Instability of autonomic nervous and immune rhythms. Morning stiffness, night sweats, abnormal temperature regulation, and day-night fatigue patterns.
• Liver and Kidney Deficiency (肝腎不足): Decline in recovery mechanisms due to chronic disease. Osteoporosis, dry eyes, and decreased memory/concentration.
• Blood Stasis and Phlegm Coagulation (瘀血痰結): Tissue changes left by past inflammation. Local stiffness, micro-movement disorders, and weather sensitivity.

This gap is not simply a matter of "the medicine being less effective," but a state where recovery and reconstruction have not properly occurred even after the body has escaped inflammation. TKM treatment approaches this by supplementing Qi and Blood, harmonizing Ying and Wei, and resolving blood stasis and phlegm.

Integrated Decision-Making Signals: When to Lead and What to Add

When Modern Medicine Should Lead

• Initial 3 to 6 months: Early DMARD window. Suppressing disease activity before joint destruction begins determines the long-term prognosis.
• RF/anti-CCP positive, polyarticular involvement, high DAS28-CRP: Specialist rheumatology care and csDMARDs-based T2T (Treat-to-Target) strategy are priorities.
• Rapid progression, lung/vascular/heart complications, signs of infection, or severe ocular complications: These are red flags requiring specialist evaluation.

The Value Added by Traditional Korean Medicine

• Additional improvement in pain, stiffness, and inflammatory markers when combined with standard treatment (2024 TKM Clinical Practice Guidelines, GRADE-based recommendation).
• Management of residual symptoms, fatigue, sleep, digestion, and quality of life.
• Protective approach for gastrointestinal, liver, and kidney functions against long-term drug use.
• Pattern-based personalization: Even for the same RA, prescription and acupuncture strategies differ between the Wind-Cold-Damp Bi type and the Qi-Blood Deficiency type.

Combination Methods

• Initial stage: Suppress disease activity with conventional drugs while supporting the reduction of pain, stiffness, and side effects with TKM treatment.
• Stable stage: Decisions on reducing or maintaining conventional drugs are made in consultation with a rheumatologist. TKM treatment continues toward enhancing fundamental recovery power, focusing on Qi-Blood, Liver-Kidney, and the gut-joint axis.
• Refractory (D2T) state: Instead of simple drug escalation, re-evaluate TKM patterns and check the intestinal environment, stress, sleep, and nutrition together.

Perspective on Fundamental Recovery (Self-Healing Power)

Modern medicine's T2T strategy aims to suppress disease activity to near zero. This is essential for preventing joint destruction. TKM adds to this by cultivating the body's ability to regulate inflammation, regenerate Qi and Blood, and restore immune rhythms. Symptom suppression and fundamental recovery are not in conflict. Rather, they are two axes with different timings and purposes.

RA is a difficult disease to cure completely. However, even if not a "cure," it is a fully achievable goal to create a state where one can open fingers in the morning, type on a keyboard, stand for family, and maintain daily life even when the weather is bad. Integrative medicine is the process of modern medicine and TKM reaching that goal together.

Integrated Pathophysiology Flowchart

Integrative Medicine Treatment Approach

An integrative medicine treatment approach is not about deciding "which treatment is better," but rather about accurately positioning what role each treatment plays at which stage of the patient's journey. RA varies significantly from person to person in terms of progression stages and pattern identification (syndromes). Some find morning stiffness to be their primary issue, some have weakened gastrointestinal systems due to long-term medication, and others already have progressed joint deformities. Therefore, treatment must be tailored to the stage, constitution, and accompanying symptoms.

Modern medicine focuses on preventing structural destruction and systemic inflammation. In cases of early RA, high disease activity, anti-CCP positivity, or signs of bone erosion, the proactive use of DMARDs (such as methotrexate), biological agents, or targeted synthetic agents is crucial for preserving joint function. In particular, the first 3 to 6 months after onset is the "golden time" for treatment; delaying inflammation control by relying solely on Korean Medicine during this period is dangerous. Professional evaluation and medication adjustment in modern medicine take priority when there are signs of fever, severe edema, rapid progression of joint destruction, complications in the lungs, blood vessels, or heart, or concerns about infection.

Korean Medicine shows its strength in addressing residual symptoms, drug side effects, functional recovery, reduction of recurrence, and holistic quality of life within those gaps. For example, many patients still experience morning stiffness despite taking anti-rheumatic drugs, or suffer from coldness and numbness in the hands and feet, gastrointestinal discomfort, and chronic fatigue. These conditions are often not fully explained by modern laboratory values, yet they significantly restrict the patient's daily life. Korean Medicine interprets these as Qi and Blood deficiency (氣血虛損), disharmony between Ying and Wei (營衛不和), or residual Dampness and Blood Stasis (濕·瘀血), and treats them according to the individual's pattern identification.

The main pattern types and clinical approaches are mapped as follows. The Wind-Cold-Dampness Bi (風寒濕痺) type is characterized by pain that migrates, worsens with cold and humidity, and presents with distinct morning stiffness. Modernly, this can be seen as a phenotype prominent in early or low disease activity stages or seasonal exacerbations; formulas like Du Huo Ji Sheng Tang (Dokhwalgisaeng-tang) or Ge Gen Tang (Galgeun-tang) series are used to dispel Wind-Dampness and remove Cold-Dampness. The Wind-Dampness-Heat Bi (風濕熱痺) type occurs when joints are red, hot, swollen, and the pain is intense. This corresponds to stages of acute flare-ups, high disease activity, or severe synovial inflammation; formulas such as Bai Hu Jia Zhu Fu Zi Tang (Baekhogachulbuch-tang) or Dang Gui Nian Tong Tang (Danggwigoyak-tang) are considered to clear Heat evil and remove Dampness. However, at this stage, modern medical inflammation suppression must be performed in parallel to prevent joint destruction.

The Phlegm and Blood Stasis Obstruction (痰瘀血滯) type is a chronic state where joints stiffen, deformities or nodules appear, and pain becomes fixed. Modernly, this corresponds to the stage of structural damage where pannus formation and cartilage/bone destruction have progressed. Aiming for blood circulation to remove stasis (活血祛瘀) and resolving phlegm to dissipate nodules (祛痰散結), the Shen Qi Wan (Singi-hwan) or Huo Xue Qu Yu Tang (Hwalhyeolsaeo-tang) series are used, and combining these with physical therapy and exercise rehabilitation helps in functional recovery. The Qi and Blood Deficiency (氣血兩虛) type is when chronic fatigue, anemia, anorexia, and decreased immunity are prominent. This is commonly seen in states of exhaustion due to long-term medication or inflammation, and in D2T-RA; Shi Quan Da Bu Tang (Sipjeondaebo-tang) or Bu Zhong Yi Qi Tang (Bojungikgi-tang) are used to replenish Qi and Blood and restore Vital Qi (正氣). The Liver and Kidney Deficiency (肝腎不足) type is when joint deformity progresses and is accompanied by back pain, osteoporosis, and sarcopenia. This is common in the elderly or chronic progressive RA; Du Huo Ji Sheng Tang, Si Jun Zi Tang (Sagunja-tang), or Da Fang Feng Tang (Daebangpung-tang) are used to tonify the Liver and Kidney and strengthen bones and muscles.

These patterns change over time even within the same person. Heat Bi may be prominent in the early stages, but as it becomes chronic, Phlegm-Blood and deficiency patterns overlap, and after long-term treatment, Qi-Blood and Liver-Kidney deficiencies often become prominent. Therefore, Korean Medicine treatment requires a dynamic approach that tracks changes in pattern identification by stage, rather than a fixed prescription.

The specific methods of collaborative integration are as follows. In early and active RA, modern medicine's DMARDs/tsDMARDs/bDMARDs lead the suppression of inflammation and structural damage, while Korean Medicine complements by alleviating drug side effects, managing residual symptoms, and addressing stress and sleep. In chronic and low-activity stages, Korean Medicine plays a more active role in stiffness, fatigue, functional recovery, and prevention of recurrence, while modern medicine monitors disease activity through regular imaging and blood tests. In Difficult-to-Treat RA (D2T-RA), cases often cannot be resolved by simple medication escalation alone. Here, Korean Medicine addresses immunity, the intestinal environment, Ying-Wei, and psychosomatic factors together, while modern medicine continuously evaluates red flags such as infection, malignancy, and cardiovascular or pulmonary complications. In cases where joint deformity requiring surgery has occurred, orthopedic evaluation and rehabilitation take priority, and Korean Medicine assists in functional recovery and pain control before and after surgery.

The "Korean Medicine Clinical Practice Guideline for Rheumatoid Arthritis," first published in Korea in 2024, formalized this integrative perspective. It provided GRADE-based recommendations for acupuncture, moxibustion, herbal medicine, pharmacopuncture, thread embedding, and acupotomy, and notably included several recommendations stating that Korean Medicine treatment should be considered in conjunction with Western medical treatment. Meta-analyses also showed that acupuncture combined with Western medicine had additional effects on Tender Joint Count (TJC), Swollen Joint Count (SJC), ESR, CRP, and ACR response rates, and moxibustion therapy was also reported to be superior in clinical effective rates and pain improvement.

The perspective of fundamental recovery is different from simply "making the inflammation markers zero." When suffering from RA for a long time, one may experience a heavy body even when markers are normal, joints reacting first whenever the weather changes, and anxiety when reducing medication. This means that even if inflammation has disappeared, Qi and Blood circulation, immune balance, the gut-brain-joint axis, and resilience have not fully recovered. Korean Medicine focuses on increasing this resilience. Along with suppressing symptoms, it aims to cultivate internal stability so the body can regulate inflammation itself, become less sensitive to weather changes, and gradually reduce drug dependency.

In this process, what the patient can do themselves is also important. Regular low-intensity aerobic exercise, joint range-of-motion exercises, sufficient sleep, stress management, and dietary habits that support gut health are all part of the treatment. The 2022 ACR Guideline for Integrative Interventions also includes recommendations for exercise, rehabilitation, diet, and complementary therapies, and Korean Medicine can provide more specific guidance on these lifestyle therapies from a pattern identification perspective.

Ultimately, the integrative medical treatment of RA is about "Modern medicine that suppresses inflammation" and "Korean Medicine that restores the body's balance" recognizing each other's strengths and organically connecting according to the patient's stage and needs. For young patients, early joint preservation and reducing the lifelong burden of medication are important; for long-term medication users, side effect management and residual symptom recovery are important; and for the elderly, preventing deformity and managing comorbidities are important. In all these situations, Korean Medicine does not replace modern medicine but stands as a complementary and personalized treatment to create a better daily life together.

Evidence

Evidence for rheumatoid arthritis (RA) is formed at the intersection of modern medicine's pathophysiology, clinical trials, and standard guidelines, and Korean medicine's syndrome differentiation treatment, acupuncture, and systematic reviews, meta-analyses, and national clinical practice guidelines regarding herbal medicine. The two systems explain the same clinical phenomena in different languages, and the validity of an integrative medical approach is revealed only when these dual languages complement each other.

The starting point of modern medical evidence is the pathophysiology of RA. RA is a disease in which chronic inflammation initiated in the synovium leads to synovial hypertrophy, angiogenesis, and pannus formation, eventually destroying cartilage and bone. Key mechanisms include the excessive secretion of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6, Th17/Treg imbalance, B-cell and autoantibody (RF, anti-CCP) involvement, RANKL-mediated osteoclast activation, and VEGF/VCAM-1-related synovial angiogenesis. These mechanisms are systematically organized in the 2024 American Family Physician review on RA diagnosis and management and the 2024 revised Chinese RA diagnosis and treatment guidelines.^[1][2] Diagnostic criteria follow the 2010 ACR/EULAR RA classification criteria, which comprehensively evaluate joint involvement patterns, RF/anti-CCP, CRP/ESR, and symptom duration. NICE guidelines recommend prompt referral to a rheumatologist if there is polyarticular or small joint pain and stiffness persisting for more than 3 weeks.^[3] Standard treatment is a Treat-to-Target (T2T) strategy based on csDMARDs (methotrexate, etc.), bDMARDs (TNF inhibitors, IL-6 receptor antagonists, CTLA-4-Ig, CD20 antibodies, etc.), and tsDMARDs (JAK inhibitors).^[2]

However, despite standard treatment, significant unmet needs exist. There is a patient group with difficult-to-treat RA (D2T-RA) who do not reach low disease activity or remission despite receiving T2T strategies; this is related to multidimensional factors such as psychosocial distress, comorbidities, chronic pain syndromes, and patient/system-related barriers, rather than simple drug resistance.^[4][5] Furthermore, approximately 40% of RA patients do not respond to individual biological agents, which is why predictive models based on synovial tissue RNA-seq are being developed through precision medicine biomarker research (STRAP, R4RA trials).^[6][7] Issues regarding the long-term safety of bio/tsDMARDs, side effects involving infection, malignancy, liver, kidney, and cardiovascular systems, costs, and quality of life issues such as pain, fatigue, sleep disorders, depression, and functional decline are also continuously raised.^[8]

Korean medicine evidence is centered on the Korean Medicine Clinical Practice Guideline for Rheumatoid Arthritis, developed for the first time in Korea in 2024. This guideline provides GRADE-based recommendations for acupuncture, moxibustion, pharmacopuncture, herbal medicine, acupotomy, and thread-embedding therapy, and recommends the combination of acupuncture with herbal medicine, moxibustion, pharmacopuncture, thread-embedding, integrative Korean medicine treatment, or acupotomy alongside conventional medicine at the level of "should be considered" (B) or "can be considered" (C).^[9][10][11] Korean medicine classifies RA as Bi-syndrome (痺證) or Yeokjeolpung (歷節風), viewing the etiology and pathogenesis as the invasion of pathogenic factors such as Wind, Cold, Dampness, and Heat (風寒濕熱) and the weakness of vital energy (正氣) such as Liver-Kidney deficiency, Qi-Blood deficiency, and disharmony between Ying and Wei (營衛).^[12]

Modern research evidence for acupuncture therapy is relatively well-accumulated. In a 2022 meta-analysis by Li et al. (11 RCTs), acupuncture significantly improved VAS pain, TJC, SJC, CRP, RF, and ESR in RA patients, and the effect was reported to be even superior when combined with conventional medicine.^[13] In the same year, a network meta-analysis of 32 RCTs involving 2,115 subjects showed that acupuncture combined with conventional medicine had superior effects on ACR20/50/70, TJC, SJC, ESR, and CRP.^[14] Mechanism studies explain that acupuncture exerts multiple actions, including regulating the macrophage M1/M2 balance, restoring the Treg/Th17 balance, reducing TNF-α, IL-1β, and IL-6, providing antioxidant and anti-inflammatory effects through Keap1-Nrf2/ARE/HO-1 pathway activation, inhibiting osteoclastogenesis by reducing RANKL, inhibiting synovial angiogenesis by reducing VEGF/VCAM-1, and modulating the adenosine, opioid, and brain-endocrine-immune networks.^[15][16][17] A 2014 meta-analysis on moxibustion therapy (8 RCTs) showed a significant advantage in clinical effective rate for both moxibustion alone and in combination with conventional medicine, with conventional medicine + moxibustion recording an RR of 1.57 for ACR50.^[18]

Research on herbal medicine is also active. Numerous meta-analyses and network meta-analyses have reported that herbal medicine intake shows additional effects in improving pain, stiffness, inflammatory markers, functional indices, and ACR response rates when combined with conventional medicine. Representative prescriptions such as Duhuo Jisheng-tang, Baekhogachulgakja-tang, Danggui Goyak-tang, Hwalhyeol Saeo-tang, and Sipjeon Daebo-tang are utilized clinically according to syndrome differentiation types.^[19] Individual case studies have also reported instances where modifications of Xiao Chaihu-tang (小柴胡湯) based on the Shanghan Lun syndrome differentiation system contributed to the improvement of RA symptoms.^[20]

Integrative and functional medicine approaches address multidimensional factors such as the gut-joint axis, intestinal permeability, the microbiome, nutrition, exercise, stress, and sleep. The 2022 ACR guidelines also included recommendations for exercise, rehabilitation, diet, and integrative interventions.^[21]

These evidences suggest that Korean medicine treatment is not a simple complement, but of RA

Frequently Asked Questions

Q1. Is Rheumatoid Arthritis (RA) incurable? How does Korean Medicine approach it differently?

Modern medicine views RA as a chronic systemic autoimmune disease, with the primary goals being the suppression of disease activity and the maintenance of remission. Instead of the word "cure," the core focus is on preventing joint destruction and preserving function through early intervention.

Korean Medicine interprets RA as Bi-jeung (痺證, Bi syndrome) or Yeokjeolpung (歷節風). Rather than simply suppressing inflammation, it traces why the immune system began attacking itself. The pathogenesis (Byeonggi, 病機) is viewed as a process where external pathogens—Wind, Cold, Dampness, and Heat—invade when the body's vital energy (Jeong-gi, 正氣) is weakened, leading to blocked circulation of Qi and Blood and the accumulation of Phlegm-fluid (Dam-eum, 痰飮) and Blood Stasis (Eo-hyeol, 瘀血). Therefore, unlike approaches that only suppress symptoms, treatment is designed to restore the body's self-healing capacity and reduce immune dysfunction. This does not conflict with the suppression of disease activity in modern medicine; there is evidence that combined treatment provides additional benefits in pain, stiffness, inflammatory markers, and quality of life.

Q2. I was diagnosed with rheumatoid arthritis at a young age; do I have to take medication for the rest of my life?

The incidence of RA is steadily increasing among people in their 20s and 30s, and it occurs about three times more often in women than in men. Early management is crucial because the first 3 to 6 months represent a "critical window" for minimizing joint destruction. During this period, prioritizing DMARDs (Disease-Modifying Antirheumatic Drugs) treatment in modern medicine is the standard.

Korean Medicine can play a role during this period by combining immune regulation with the improvement of Qi and Blood circulation, building a foundation for the body to reduce drug dependency. However, the decision to discontinue medication must be made jointly by a rheumatologist and a Korean Medicine doctor, integrating blood tests, imaging, and clinical findings. Abruptly stopping medication can cause recurrence or rebound phenomena, so adjustments must be gradual and based on objective indicators. Evidence:^[3]

Q3. Is it okay to use herbal medicine or acupuncture while taking anti-rheumatic drugs?

The Korean Medicine Clinical Practice Guideline for Rheumatoid Arthritis, developed for the first time in Korea in 2024, provides GRADE-based recommendations for acupuncture, moxibustion, pharmacopuncture, herbal medicine, acupotomy, and thread-embedding therapy. In particular, when combined with Western medicine, acupuncture, moxibustion, pharmacopuncture, and complex Korean Medicine treatments have evidence at the level of "should be considered" (Grade B recommendation).

Meta-analyses have also shown that acupuncture combined with Western medicine is highly effective for ACR20/50/70, TJC (Tender Joint Count), SJC (Swollen Joint Count), ESR, and CRP. Moxibustion combined with Western medicine showed an effect with an RR of 1.57 for ACR50. When using combined therapy, it is important to check for interactions between the medications and herbal medicine and to regularly monitor liver and kidney function. This requires sharing clinical information between the Korean Medicine doctor and the rheumatologist. Evidence:^[14]

Q4. My test results are normal, so why are my fingers still stiff and painful?

This is the issue of "residual symptoms" commonly experienced by RA patients. Even if CRP and ESR have normalized in modern medicine, morning stiffness, minor pain, fatigue, sleep disorders, and functional decline may persist. Korean Medicine interprets this as Qi and Blood circulation not yet being smooth, disharmony between Yeong (Nutritive Qi) and Wi (Defensive Qi), residual Phlegm-fluid, Blood Stasis, or weakened vital energy.

In particular, morning stiffness reflects a state where the circulation of Yeong-Wi has slowed down overnight. Gastric weakness or Liver-Kidney deficiency caused by long-term medication manifests as systemic fatigue and delayed recovery. These conditions are approached by promoting the flow of Qi and Blood, harmonizing Yeong-Wi, and tonifying vital energy through herbal medicine, acupuncture, and moxibustion. Evidence:^[5]

Q5. Why does the pain get worse during the rainy season or in winter?

Environments with high humidity and low temperatures tend to exacerbate RA symptoms. In Korean Medicine, Wind (Pung, 風), Cold (Han, 寒), and Dampness (Seup, 濕) are representative external pathogens (Oesa, 外邪) of Bi-jeung. Cold causes the contraction of Qi and Blood, worsening pain and stiffness; Dampness is heavy and turbid (Jung-tak, 重濁), causing the body to feel heavy and swollen; and Wind is characterized by migrating pain.

This aligns with the modern medical perspective that weather changes affect synovial fluid viscosity, vascular response, and pain sensitivity. Korean Medicine management utilizes prescriptions that dispel Wind-Cold-Dampness along with moxibustion and acupuncture according to the season, while simultaneously managing lifestyle by avoiding dampness and maintaining body temperature.

Q6. My stomach has become weak and I feel very fatigued because of rheumatoid arthritis; should these be treated as well?

Yes. Although RA is a joint disease, it actually has systemic effects. In particular, long-term use of NSAIDs, steroids, and DMARDs can be accompanied by gastrointestinal disorders, elevated liver enzymes, decreased immunity, and chronic fatigue. Korean Medicine interprets this through pattern identification (Byeon-jeung) such as Deficiency of both Qi and Blood (Gi-hyeol-yang-heo), Spleen-Stomach Weakness (Bi-wi-heo-yak), or Liver-Kidney Deficiency (Gan-sin-bu-jok), and performs treatments to tonify Qi, nourish Blood, and strengthen the stomach using formulas like Bojungikgi-tang, Sipjeondaebo-tang, or Sagunja-tang.

Furthermore, RA patients are at a higher risk for comorbidities such as cardiovascular disease, osteoporosis, depression, and dry eye syndrome (Sjogren's syndrome). Therefore, it is necessary to comprehensively care for gastrointestinal function, nutritional status, sleep, stress, and exercise as much as pain management. This is the significance of an integrative medical approach in RA treatment. Evidence:^[21]
