Saraca asoca has been traditionally used in Indian system for treatment of uterine, genital, and other reproductive disorders in women, fever, pain, and inflammation. The hypothesis of this study is that acetone extract of Saraca asoca seeds is an effective anti-inflammatory treatment for arthritis in animal experiments. The antiarthritic effect of its oral administration on Freund’s adjuvant-induced arthritis has been studied in Wistar albino rats after acute and subacute toxicities. Phytochemical analysis revealed presence of high concentrations of phenolic compounds such as flavonoids and tannins, while no mortality or morbidity was observed up to 1000 mg/kg dose during acute and subacute toxicity assessments. Regular treatment up to 21 days of adjuvant-induced arthritic rats with Saraca asoca acetone extract (at 300 and 500 mg/kg doses) increases RBC and Hb, decreases WBC, ESR, and prostaglandin levels in blood, and restores body weight when compared with control (normal saline) and standard (Indomethacin) groups. Significant () inhibitory effect was observed especially at higher dose on paw edema, ankle joint inflammation, and hydroxyproline and glucosamine concentrations in urine. Normal radiological images of joint and histopathological analysis of joint, liver, stomach, and kidney also confirmed its significant nontoxic, antiarthritic, and anti-inflammatory effect.
