Antioxidant and anti-inflammatory property of Sandhika: a compound herbal drug

The present study was envisaged to assess the rationality for the use of "Sandhika", a popular Ayurvedic drug in rheumatoid arthritis. This drug, when tested against carrageenan induced paw oedema and cotton pellet granuloma, showed significant anti-inflammatory activity at the dose of 0.25 g/kg body weight. The antioxidant property was assessed by determining cumene hydroperoxide (CHP) induced lipid peroxidation and reduced glutathione content in rat liver homogenate (in vitro). Experiments show the significant protection against lipid peroxidation at the dose of 80 micrograms/ml, measured as reduction in the level of malondialdehyde (MDA) induced by 1.5 mM cumene hydroperoxide (CHP). This effect was accompanied by the maintained reduced glutathione (GSH) content in drug treated rats. Oral treatment of drug up to 2 g/kg body weight for 15 days did not show any rise in serum transaminases (SGOT and SGPT). The results suggest that "Sandhika" which is an indigenous drug for inflammation with no detectable adverse effect, might be acting through scavenging the free radicals.
