The aim of this study is to evaluate the decoction of fresh rhizome, decoction of dried rhizome, essential oils, and curcumin of Curcuma xanthorrhiza Roxb. against bilirubin level on paracetamol-induced male Wistar rats. Male Wistar rats were divided into 10 groups including group I and II were normal control and negative control, groups III, IV, and V received pretreatment of decoction of fresh rhizome 0,75 g/kgBW, 2,25 g/kgBW, and 6,75 g/kgBW, respectively for 9 days, Groups VI, VII, and VIII received pretreatment of decoction of dried rhizome 0,45 g/kgBW, 1,35 g/kgBW, and 4,05 g/kgBW, respectively for 9 days, group IX received pretreatment of essential oils 1,01 μl/kgBW for 9 days, group X received pretreatment of curcumin 75 μg/kgBW for 9 days.
