A rich source of EPA and DHA omega-3 fatty acids, commonly used to support cardiovascular health and reduce inflammation.
Omega-3 fatty acids — specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) — are polyunsaturated fats that the human body cannot synthesize de novo. They must be obtained from dietary sources, primarily fatty fish (salmon, mackerel, sardines, anchovies), shellfish, and marine algae. EPA and DHA serve as structural components of cell membranes throughout the body, with particularly high concentrations in the brain (DHA comprises roughly 40% of polyunsaturated fatty acids in the brain) and retina. Beyond structural roles, they are precursors to specialized pro-resolving mediators (SPMs) — resolvins, protectins, and maresins — that actively resolve inflammation rather than simply suppressing it. The evidence base for omega-3 supplementation is extensive. Large-scale trials and meta-analyses support benefits for cardiovascular health (triglyceride reduction, modest blood pressure lowering), inflammatory conditions, mood disorders, and cognitive maintenance. The American Heart Association recommends at least two servings of fatty fish per week, and higher-dose EPA supplementation has been shown to reduce cardiovascular events in the REDUCE-IT trial.

Osteoarthritis (OA) is the most common arthritis, driven by age, mechanical loading, prior injury, obesity, and genetics. It features progressive cartilage loss, subchondral bone changes, synovial activation, and periarticular muscle weakness. Patients typically report activity-related joint pain, stiffness (often <30 minutes in the morning), reduced function, and sometimes swelling or crepitus. Knees, hips, hands, and spine are most affected. Diagnosis is clinical, supported by radiographs showing joint-space narrowing, osteophytes, and sclerosis; MRI is rarely required for routine care. Western management prioritizes nonpharmacologic strategies with the strongest, most consistent benefits across guidelines: education, exercise therapy (aerobic, strengthening, neuromuscular/balance), and weight reduction for those with overweight/obesity. Topical NSAIDs are recommended as first-line pharmacologic therapy for knee and hand OA, with oral NSAIDs used when needed and appropriate. Acetaminophen has diminishing evidence of benefit. Duloxetine can help chronic OA pain, particularly knee OA. Intra-articular corticosteroid injections offer short-term relief; hyaluronic acid remains controversial with mixed evidence. Platelet-rich plasma (PRP) injections are emerging but heterogeneous and not yet guideline-endorsed broadly. Joint replacement is highly effective for end-stage disease. Eastern and traditional approaches conceptualize OA differently but often converge on movement-based and symptom-relieving therapies. In Traditional Chinese Medicine (TCM), OA commonly maps to Bi syndrome (painful obstruction) with patterns such as wind-cold-damp Bi, blood stasis, and kidney (shen) deficiency. Treatment may include acupuncture (including electroacupuncture and warm-needle techniques), moxibustion, topical herbal liniments (e.g., capsicum), tuina/manual therapy, and herbal formulas (e.g., Du Huo Ji Sheng Tang). Acupuncture for knee OA is among the best-studied TCM applications,
Rheumatoid arthritis (RA) is a chronic, systemic, autoimmune synovitis that, without timely control, leads to pain, progressive joint damage, disability, and increased cardiovascular risk. Western medicine defines RA by characteristic clinical patterns, serologic autoantibodies, and inflammatory markers, and prioritizes early, aggressive disease modification using a treat‑to‑target strategy. This approach, guided by rigorous randomized trials and international guidelines, has transformed outcomes—many patients can now achieve low disease activity or remission and preserve function. Diagnosis in Western practice uses ACR/EULAR classification criteria that integrate joint involvement, rheumatoid factor (RF) and anti‑cyclic citrullinated peptide (anti‑CCP) antibodies, acute‑phase reactants (ESR/CRP), and symptom duration. Imaging (ultrasound/MRI) can detect subclinical synovitis and erosions early. Management begins promptly—ideally within weeks of symptom onset—because early window therapy improves long‑term trajectories. First‑line conventional synthetic disease‑modifying antirheumatic drugs (csDMARDs) include methotrexate (anchor), sulfasalazine, hydroxychloroquine, and leflunomide. If targets (remission/low disease activity) are not met, biologic DMARDs (e.g., TNF, IL‑6, T‑cell costimulation, anti‑CD20) or targeted synthetic JAK inhibitors are added or substituted, with iterative monitoring every 1–3 months and shared decision‑making. Short glucocorticoid courses are sometimes used as a bridge, while NSAIDs treat pain but do not alter disease course. Safety monitoring, vaccination, infection screening, and comorbidity risk reduction (e.g., cardiovascular prevention, bone health, smoking cessation, exercise, rehabilitation) are integral. Eastern and traditional systems conceptualize RA differently but share aims of reducing pain, swelling, and functional limitations while preventing chronic deterioration. Traditional Chinese Medicine (TCM) frames RA within “Bi” (B
