The anti-inflammatory and analgesic activity of various extracts of Ficus glomerata Roxb. were evaluated in experimental animals. We have determined the anti-inflammatory and analgesic activity of various extracts of the dried fruits of Ficus glomerata by oral administration at doses of 200 and 400 mg/kg of body weight to healthy animals. The extracts were studied for their anti-inflammatory activity in carageenan induced hind paw edema in rats and the paw volume was measured plethysmometrically after 3 hours of injection. The extracts were also evaluated for analgesic activity using Eddy’s hot plate method in Swiss albino mice. The extracts of Ficus glomerata significantly reduced carageenan induced hind paw edema in rats and analgesic activity evidenced by increase in the reaction time by Eddy’s hot plate method in Swiss albino mice. The extracts showed a similar anti-inflammatory and analgesic effect comparative to the standard drugs indomethacin and diclofenac sodium respectively. The present results indicated the ethanolic extract of Ficus glomerata exhibited more significant activity than other extracts in the treatment of pain and inflammation.

Introduction: Seaweeds are valuable resources for the discovery of efficient and safe drugs for pain treatment. In the present investigation, we evaluated the antinociceptive and anti-inflammatory properties of, methanolic extract of Laurencia caspica, a red algae, in mice models. Methods: The analgesic effect of methanolic extract of L. caspica was assessed by hot-plate and acetic acid-induced writhing tests in male Swiss albino mice (weight = 20-25 g). The anti-inflammatory activity of methanolic extract of L. caspica was also evaluated by formalin-induced ear edema and xylene-induced paw edema tests. Results: The total flavonoid content of the extract was estimated as 0.0537 mg quercetin/g extract. Both first and second phases of the nociception were significantly inhibited at a dose of 120 mg/kg of methanolic extract of L. caspica. The observed anti-inflammatory effect was dose-dependent. Acetic acid-induced writhing test and hot plate test showed that the extract significantly reduced pain in all evaluated doses (15, 30, 60, and 120 mg/kg). The antinociceptive activity of the methanolic extract was significantly reduced by naloxone (4 mg/kg). Moreover, the extract significantly reduced paw edema at the dose of 120 mg/kg in all the animals. Conclusion: Methanolic extract of L. caspica exhibited central analgesic effect, as well as anti-inflammatory activity probably due to the presence of constituents like flavonoids and triterpenoids.

Aim: This research was designed to evaluate the anti-inflammatory and analgesic activities of Parinari curatellifolia methanol leaf extract in albino rats. Methodology: Phytochemical screening was carried out using standard methods. Anti-inflammatory activity of the extract was done using egg albumin and formalin induced hind paw edema model. Analgesic effect was evaluated using hot plate induced pain and acetic acid induced writhing test. For each model twenty (20) rats were used, divided into five (5) groups of four (4) rats each. Results: Parinari curatellifolia revealed the presence of alkaloids, flavonoids, tannins and phenols while steroids, anthraquinone, terpenoids and glycoside were not detected. For the egg albumin induced inflammation, the group treated with the standard drug (indomethacin) and the group that received the highest dose of the extract were significantly lower (P<0.05) than all the other groups with percentage inhibitions at 25.56% and 24.44% respectively there was no significant difference (P>0.05). For the formalin induced anti-inflammatory activity, at the 1st hour, the normal control group had its paw volume significantly different (P<0.05) from the treated groups. This trend was observed at the 2nd, 3rd and 4th hour. The hot plate method results revealed significant increased (P<0.05) in the analgesic activity of PCMLE at 400mg/kg body weight and the drug treated group when the control was compared with the treated groups with percentage inhibition of 34.32% and 52.94% respectively. The acetic acid induced writhing test revealed that the extract at the three doses of 100, 200 and 400 mg/kg body weight, showed a significant (P<0.05) percentage inhibition of 32.31%, 36.92% and 47.69%, respectively compared to negative control. Conclusion: This justifies the use of Parinari curatellifolia locally in the management of pain and inflammation.

Introduction: Guazuma ulmifolia (Sterculiaceae) is commonly used in folk medicine as a single drug remedy to treat various ailments like; skin diseases, headache, wounds, ulcers, asthma, kidney disease and malaria. However, the use of the herb for treatment of pain and inflammation has not been scientifically investigated. Objective: This study of 80% methanolic crude extract of the leaves of Guazuma ulmifolia was evaluated for its analgesic and anti-inflammatory properties using established animal models. Material and methods: Wister albino rats were randomly divided into four groups of six rats per group. The control group was orally given 2 ml/kg (p.o.) of distilled water. The positive control received standard drug (Diclofenac 10 mg//kg, Indomethacin 20 mg/kg). The rest of the groups were treated with 80% methanolic extract of Guazuma ulmifolia at doses of 250 and 500 mg/kg. Animals were then subjected to tests using hot plate and tail-clip for analgesic activity, for anti-inflammatory activity carrageenan-induced paw edema test and histamine-induced paw edema test was used. Result and Discussion: Guazuma ulmifolia extract showed a dose-dependent significant reduction of pain in analgesia models (p<0.001) with 500 mg/kg dose producing the highest reduction. The extract significantly reduced carrageenan-induced inflammation in a dose-independent manner, in which the highest reduction of inflammation was observed at 500 mg/kg. Conclusion: The data collectively indicate that 80% methanolic extract of Guazuma ulmifolia leaves has potential analgesic and anti-inflammatory activities.
