This study aimed to assess the anti-inflammatory and analgesic effects of Fructus Rosae Multiflorae (FIRM, hips of Rosa multiflora Thunb.). FRM was extracted with 75% ethanol and the dried extract (FRME) was administered intragastrically (i.g.) at 100, 200 and 400 mg/kg. The anti-inflammatory effect was evaluated in four experimental animal models and analgesic effect in two animal models. Pretreatment with a single dose of FRME produced significant dose-dependent anti-inflammatory effects on carrageenin-induced rat hind paw edema, xylene-induced mouse ear edema and acetic acid-induced mouse vascular permeation. In a 7-day study, daily administration of FRME suppressed cotton pellet-induced rat granuloma formation. Pretreatment with a single dose of FRME also produced dose-dependent anti-nociceptive effects in thermally- and chemically induced mouse pain models. In addition, a single dose of FRME at 2.4 g/kg body weight (equivalent to 87.6 g of dried hips per kg body weight) produced no observable acute toxicity in mice within seven days. These results demonstrate that FRME possesses anti-inflammatory and analgesic effects and has no obvious acute toxicity, which advanced our understanding of the folk use of FRM in treating various inflammatory disorders.
