In rats with induced arthritis and stress, daily oral eucalyptol at 200 mg/kg for 14 days reduced joint swelling by 62%, increased grip strength by 172%, and restored joint tissue structure compared...
Mechanism
Synthesis from 1 study
Eucalyptol stops the chain reaction that makes joints swell and break down by blocking harmful signals and boosting the body's natural repair systems. This reduces swelling, protects cartilage, and lets the rats move better.
Most probable mechanism
Eucalyptol enters the bloodstream and reaches the joints, where it blocks key signaling pathways that trigger inflammation and oxidative damage. This stops the production of harmful chemicals that swell joints and destroy cartilage. It also boosts the body's natural defenses against cell damage. As a result, joint swelling decreases, cartilage stops breaking down, and movement improves.
Eucalyptol is absorbed from the gastrointestinal tract and distributed to joint tissues via systemic circulation
Eucalyptol inhibits phosphorylation of MAPK kinases and prevents nuclear translocation of NF-κB in synovial and chondrocyte cells
Inhibition of NF-κB and MAPK signaling reduces transcription of pro-inflammatory cytokines TNF-α and IL-6
Reduced cytokine levels decrease recruitment and activation of immune cells in the synovium, limiting pannus formation and joint inflammation
Eucalyptol directly scavenges reactive oxygen and nitrogen species and increases activity of superoxide dismutase and catalase
Enhanced antioxidant activity reduces lipid peroxidation and oxidative damage to cartilage and synovial cells
Suppression of NF-κB and MAPK pathways downregulates expression of matrix metalloproteinase-9 and RT1A
Reduced MMP-9 activity preserves collagen and proteoglycans in articular cartilage, preventing structural degradation
Lowered RT1A expression reduces aberrant antigen presentation to T cells, dampening autoimmune activation in joints
Preserved cartilage structure and reduced joint inflammation restore joint mobility and increase grip strength
