Background: Angelica dahurica has been used in various clinical cases. Its taste is hot and its property is warm, dry and nonpoisonous. Its efficacy is to remove wind-damp, cure swelling and edema, exhaust pus, stop itching, rhinitis and leukorrhea. Object: To test through experiment Angelica dahurica's analgesic and anti-inflammatory efficacy. Method: Inject acetic acid as a pain-inducing substance to the mice and measure visceral pain bywrithing reflex. Inject carrageenan that is an edema-inducing substance to the rat's paw and measure volume of edema. Take thermal pain to mice with plantar test and measure paw withdrawal latency. Normal group is non Angelica dahurica-treated group and treated group is Angelica dahurica-treated group. Results: In acetic acid-induced visceral model, treatment with Angelica dahurica suppressed writhing reflex significantlyand dose-dependently. In carrageenan-induced paw edema model, treatment with Angelica dahurica suppressed carrageenan-induced paw edema. In plantar test model, no significant effect on the withdrawal latency of thermal stimulation-induced nociception was observed. Conclusion: Angelica dahurica has analgesic and anti-inflammatory efficacy.

The crude ethanolic extract of the leaves of Clerodendrum viscosum (Family: Verbenaceae) was evaluated for its antioxidant and analgesic activities to investigate the scientific basis of the traditional uses. The antioxidant property of the extract was assessed by 1, 1-diphenyl -2- picryl hydrazyl (DPPH) free radical scavenging assay. The extract showed prominent antioxidant activity ($IC_{50}about{\sim}16{\mu}g/ml$) which was comparable to standard drug ascorbic acid ($IC_{50}about{\sim}15{\mu}g/ml$).The extract produced significant (P<0.001) writhing inhibition in acetic acid induced writhing in mice at the dose of 125 mg, 250 mg and 500 mg/kg body weight respectively, which were comparable to the standard drug diclofenac sodium. The results tend to suggest that the crude leaves extract at the above doses have antioxidant and analgesic activities and indicate that it might possess biologically active constituents having free radical scavenging and analgesic activities respectably.

The ethanol extract of leaves of the mangrove Aegiceras corniculatum Blanco (Myrsinaceae) was screened for its antinociceptive, antidiarrhoeal and cytotoxic activities. The extract produced significant writhing inhibition in acetic acid-induced writhing in mice at the oral dose of 250 and 500 mg/kg body weight (P < 0.001), which was comparable to the standard drug diclofenac sodium at the dose of 25 mg/kg of body weight. When tested for its antidiarrhoeal effects on castor oil induced diarrhoea in mice, it increased mean latent period and decreased the frequency of defecation significantly at the oral dose of 500 mg/kg body weight (P<0.05; P<0.01) comparable to the standard drug loperamide at the dose of 50 mg/kg of body weight. Moreover, when tested for toxicity using brine shrimp, the extract showed potent activity against the brine shrimp Artemia salina ($LC_{50}$ 10 mg/ml). The overall results tend to suggest the antinociceptive, antidiarrhoeal and cytotoxic activities of the extract.

This study was investigated on anti-inflammatory and analgesic activity on Gu-Mi-Gang-Hwal-Tang which has been used for the treatment of common cold and headache, arthralgia, fever in oriental medicine. The anti-inflammatory activities of Gu-Mi-Gang-Hwal-Tang water extract (GMGHT) on the carrageenin induced edema, acetic acid induced edema, and corton oil induced granuloma pouch in rats were examined. The analgesic effect of the GMGHT was investigated utilizing acetic acid induced writhing syndrome in mice. The antipyretic activity of the GMGHT was also investigated. The oral administration of GMGHT has been shown the anti-inflammatory activities in 1% carrageenin and acetic acid induced edema in rats. The GMGHT has been shown significant inhibitory effects on glanuloma and exudate formation in rats, especially the GMGHT (450 mg/kg) has the efficacy more than the GMGHT (150 mg/kg). The writhing syndromes induced by acetic acid in mice were inhibited, especially analgesic activity of the GMGHT (450 mg/kg) is similar to that of piroxicam and antipyretic activities were recognized in rats. In the present study, the GMGHT is indicated to have the anti-inflammatory, analgesic and antipyretic activities.

Inflammatory mediators such as interleukin-1 (IL-1), tumor necrosis $factor-{\alpha}\;(TNF-{\alpha}),\;interferon-{\gamma}\;(IFN-{\gamma})$ and lipopolysaccharide (LPS) are thought to play major roles in joint diseases such as a rheumatoid arthritis (RA), and there is considerable evidence playing a role for these cytokines in osteoarthritis (OA). Therefore, we have studied the effects on anti-inflammation and analgesic by ethyl acetate fraction from 70% ethanol extract of Artemisia capillaries (EAC). As a positive control, apigenin, which is known as an anti-inflammatory agent as an iNOS inhibitor, was used and showed the dose-dependent inhibitory effect. EAC showed strong inhibitory efficacy against cytokine-induced proteoglycan degradation, $PGE_2$ production, nitric oxide (NO) production, and matrix-matalloproteinases (MMPs) expression in rabbit articular chondrocyte. In the writhing test induced by acetic acid, EAC $(200{\sim}400\;mg/kg)$ exhibited a dose-dependent inhibition of writhing. The results indicate that EAC have anti-inflammatory and analgesic activities, and could be a good herbal medicine candidate for curing of RA and/or OA.

This study was undertaken to evaluate the antinociceptive and antiinflammatory effects of the heartwood extract of Rhus verniciflua (Anacardiaceae) and the two major components, sulfuretin and fustin. The MeOH extract, its EtOAc-soluble portion and sulfuretin showed significant antinociceptive activity in writhing and hot plate test assays and antiinflammaory effects in carrageenan-induced hind paw edema in rats. In particular, treatment of sulfuretin with 10 mg/kg dose (i.p.) reduced writhing frequency by 48.0% (p<0.01) compared to that of a control group. Further, the treatment of sulfuretin (5, 10 mg/kg, i.p.) for 7 days prevented the carrageenan-induced hind paw edema significantly (p<0.01). The antiinflammatory effect of sulfuretin was also confirmed by microscopic observation of mast cell numbers in muscle. In addition, sulfuretin suppressed the cyclooxygenase- 2 (COX-2) activity $(IC_{50}\;=\;28.7\;{\mu}M)$ in lipopolysaccharide-activated macrophage cells. This result indicates that the inhibitory effect of sulfuretin on COX-2 may be one of the antinociceptive/antiinflammatory mechanism.
