Rheumatoid arthritis (RA) is a widespread autoimmune disease that significantly impacts the lives of RA patients. It is often typified as swelling and deformation of small joints, as well as systemic inflammation. Rhodiola rosea has been utilized for millennia to treat various ailments and is known to contain numerous active compounds, including saponins, volatile oils, coumarins, and flavonoids. Recent studies have underscored the pivotal role of salidroside (SAL), a key constituent of Rhodiola rosea L. Modern research indicates that SAL has various pharmacological activities, such as its antioxidant, anti-inflammatory, anti-fatigue, and anti-cancer effects. Despite this, the pathogenesis of RA remains highly complex, and a notable lack exists in overview studies investigating the anti-RA mechanisms of SAL. Therefore, the purpose of this article is to review the present research efforts on the anti-RA mechanisms of SAL and to explore future research prospects for this compound.
