The present study evaluates the phytochemical screening, analgesic and anti-inflammatory properties of aqueous and methanolic extracts from the root of Oligomeris linifolia (OL). Pain responses were studied in mice using acetic acid writhing method and in rats using the hot plate and formalin test. The effect of the extract on edema induced by 1.5% carrageenan was also investigated. The extracts of OL exhibited significant anti-nocicetive properties against acetic acid induced abdominal constrictions in mice. In the rat the extract exhibited significant analgesic activity as evidence by (i) increased escaped latency on hot plate in the extract-treated rats and (ii) reduction in formalin-induced pain. The maximum edema rates attained in the rats pre-treated with 150mg/kg of aqueous and methanol extracts of OL (12.50 ± 2.88%, P<0.005 and 21.63 ± 3.21%, P<0.05 respectively) were significantly lower than the control value (32.62 ± 5.33%). Aspirin (150mg/kg) gave a maximum edema rate of 13.04 ± 1.98% (P<0.005). The results provide preliminary evidence for the anecdotal use of Oligomeris linifolia by traditional medical practitioners in the management of pain and inflammation.

Maerua triphylla root extracts are used by Maasai and Kikuyu communities in Kenya to manage headaches, stomachaches, migraines, and rheumatism. However, scientific data on their safety and efficacy are limited. The current study aims to investigate the safety, phytochemical constituents, analgesic, and anti-inflammatory activities of M. triphylla root extracts. Aqueous and methanol M. triphylla root extracts were prepared by cold maceration, and the extracts’ safety was evaluated using Wistar rats according to the Organization for Economic Cooperation and Development (2008) guidelines. Standard qualitative phytochemical screening methods were used for the detection of various phytochemical groups in the extracts. Analgesic activity assay in Swiss albino mice was done using the acetic acid-induced writhing test, while anti-inflammatory activity was determined in Wistar rats using the acetic acid-induced paw edema method. The methanol and aqueous extracts revealed LD50 > 2000 mg/kg bw, classifying them as nontoxic. The presence of cardiac glycosides, flavonoids, alkaloids, and phenols was observed in both extracts. However, saponins were only present in the methanol extract. In the analgesic study, mice that received 100 mg/kg bw and 500 mg/kg bw of aqueous root extract of M. triphylla had significantly lower acetic acid-induced writhing than mice that received acetylsalicylic acid 75 mg (reference drug) ( p < 0.05 ). Additionally, mice that received 500 mg/kg bw of methanol root extract of M. triphylla had significantly lower acetic acid-induced writhing than mice that received the acetylsalicylic acid 75 mg ( p < 0.05 ). In the anti-inflammatory study, there was no significant difference ( p < 0.05 ) between the inhibitory activity of different doses of the aqueous root extract of M. triphylla and a 50 mg/kg dose of diclofenac sodium (reference drug) on acetic acid-induced paw edema in rats. Moreover, there was no significant difference in the inhibitory activity of 100 mg/kg bw and 500 mg/kg bw doses of the methanol root extract of M. triphylla and a 50 mg/kg dose of diclofenac sodium on acetic acid-induced paw edema ( p > 0.05 ). These findings suggest that the roots of M. triphylla may be useful in the safe mitigation of pain and inflammation and therefore support their ethnomedicinal use in the management of pain and inflammation.

The aims of this study were to evaluate the anti-inflammatory and analgesic effects of bufalin, a major component of “Chan-su.” We used a carrageenan-induced paw edema model to assess the anti-inflammatory activity of this compound, and Western blot analysis detected NF-κB signaling during this effect. The antinociceptive activities were evaluated by acetic acid-induced writhing, formalin, and hot-plate tests; open-field test investigated effects on the central nervous system. Our data showed that bufalin (0.3 and 0.6 mg/kg, i.p.) potently decreased carrageenan-induced paw edema. Bufalin down regulated the expression levels of nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-1β(IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α(TNF-α) during these treatments. Further studies demonstrated that bufalin significantly inhibited the activation of NF-κB signaling. Bufalin also reduced acetic acid-induced writhing and the licking time in the formalin test and increased hot-plate reaction latencies. Naloxone pretreatment (2 mg/kg, i.p.) in the early phases of the formalin test and hot-plate test significantly attenuated the bufalin-induced antinociception effects, which suggests the involvement of the opioid system. A reduction in locomotion was not observed in the open-field test after bufalin administration. Taken together, bufalin treatment resulted in in vivo anti-inflammatory and analgesic effects, and bufalin may be a novel, potential drug for the treatment of inflammatory diseases.

Osteoarthritis (OA) is an age-related joint disease and one of the most common degenerative bone diseases among elderly people. The currently used therapeutic strategies relying on nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids for OA are often associated with gastrointestinal, cardiovascular, and kidney disorders, despite being proven effective. Aucklandia lappa is a well-known traditional medicine. The root of A. lappa root has several bioactive compounds and has been in use as a natural remedy for bone diseases and other health conditions. We evaluated the A. lappa root extracts on OA progression as a natural therapeutic agent. A. lappa substantially reduced writhing numbers in mice induced with acetic acid. Monosodium iodoacetate (MIA) was injected into the rats through their knee joints of rats to induce experimental OA, which shows similar pathological characteristics to OA in human. A. lappa substantially reduced the MIA-induced weight-bearing of hind limb and reversed the cartilage erosion in MIA rats. IL-1β, a representative inflammatory mediator in OA, was also markedly decreased by A. lappa in the serum of MIA rats. In vitro, A. lappa lowered the secretion of NO and suppressed the IL-1β, COX-2, IL-6, and iNOS production in RAW264.7 macrophages activated with LPS. Based on its analgesic and anti-inflammatory effects, A. lappa could be a potential remedial agent against OA.

Abstract Background To investigate the antinociceptive and anti-inflammatory activities of aqueous extract of a blended mixture of dried leaves of Ocimum gratissimum and Psidium guajava, a traditional analgesic drug polyherbal (TADP) used as a remedy for pain-related conditions. Methods Antinociceptive activity of TADP (100, 200 and 400 mg/kg) was evaluated in the hot plate test and acetic acid-induced nociception in mice while the anti-inflammatory was evaluated in carrageenan-induced paw oedema in rats. Levels of nitrite, myeloperoxidase, glutathione and malondialdehyde were assayed in carrageenan-induced paw tissue. Results TADP (200 and 400 mg/kg) significantly prolong the latency time in the hot-plate test. TADP (100–400 mg/kg) produced a dose-dependent significant inhibition of the acetic-acid induced abdominal constriction. The antinociceptive activity of TADP in the presence of naloxone and atropine was not reversed whereas yohimbine and glibenclamide significantly reversed it. TADP (100, 200 and 400 mg/kg) significantly reduced the swelling in the carrageenan-induced oedema model and also produced a reduction in the nitrite and myeloperoxidase level. TADP (400 mg/kg) significantly reduced malondialdehyde concentration and increase glutathione level in the carrageenan-induced rat paw. TADP significantly decrease the number of cellular infiltrates in the histopathological assessment. Conclusion These results indicate that polyherbal product containing blended leaves of Ocimum gratissimum and Psidium guajava possess antinociceptive and anti-inflammatory properties, hence represents a promising alternative remedy in inflammation-induced pain.

Summary Introduction: Potato (Solanum tuberosum L.) is an important vegetable crop in Syria. Potato tuber moth Cussonia barteri is a small tree that grows in the sub-Saharan part of Africa. Various parts of the plant are used for the treatment of a variety of ailments in ethno-medicine. Objective: To evaluate the anti-inflammatory and analgesic effect of the methanol leaf extract of Cussonia barteri. Material and methods: The leaves were air-dried, powdered and repeatedly extracted with methanol using a Soxhlet apparatus. The resulting methanol extract (100, 200 and 400 mg/kg) was evaluated for anti-inflammatory activity using carrageenan-induced paw oedema, xylene-induced ear oedema and formalin-induced arthritis tests. Analgesic effect was evaluated using acetic acid-induced mouse writhing, hot plate and tail flick tests. Results: All doses of the extract significantly (p<0.05) reduced carrageenan-induced paw oedema, however the 400 mg/kg dose gave a sustained effect. The extract significantly inhibited xylene induced ear oedema at all doses. There were no significant (p>0.05) reductions in paw swellings due to formalin. In the acetic acid induced writhing test, the extract significantly (p<0.05) decreased writhing at 400 mg/kg only. Reaction times were not significantly different from the control in the hot plate and tail flick tests. Conclusion: This study has shown that the methanol extract possesses acute anti-inflammatory and peripherally mediated analgesic effects.

We investigated possible mechanisms of analgesic and anti-inflammatory activities of the methanol extract from the leaf of Elaeagnus oldhamii Maxim. (EOMeOH). EOMeOHwas evaluated for its analgesic activity in acetic acid-induced writhing response and formalin test, and anti-inflammatory effect was examined by λ-carrageenan-induced paw edema assay. We detected the activities of GPx, GRd and SOD in the liver, and the levels of inflammatory mediators including IL-1β, IL-6, TNF-α, COX-2, MDA and NO in the edema paw to investigate the mechanism of action against inflammation. Total polyphenol, flavonoid and flavanol contents of EOMeOHwere detected to explore its antioxidant activities. Results showed that, in the analgesic test, EOMeOHdecreased acetic acid-induced writhing response and the licking time in the late phase of formalin test. In the anti-inflammatory test, EOMeOHdecreased paw edema at the 2nd, 3rd, 4th and 5th h after λ-carrageenan had been injected. EOMeOHincreased the activities of SOD and GPx in liver tissue and decreased MDA, NO, IL-1β, IL-6, TNF-α and COX-2 levels in paw edema tissue at the 3rd h after λ-carrageenan-induced inflammatory reaction. EOMeOHexhibited abundant polyphenol, flavonoid and flavanol contents. In HPLC fingerprint test of EOMeOH, two index ingredients, ursolic acid and pomolic acid, were isolated from EOMeOHand were exhibited in HPLC chromatographic analysis. The results demonstrated analgesic and anti-inflammatory effects of EOMeOH. It was indicated that the anti-inflammatory mechanism of EOMeOHmay be due to declined levels of NO and MDA in the edema paw through increasing the activities of SOD, GPx and GRd in the liver. Additionally, EOMeOHdecreased IL-1β, IL-6, TNF-α and COX-2 levels in the edema paw. The results suggested its value in future development of herbal medicine for the treatment of inflammatory diseases.

Background. Inflammation and pain are closely related to humans’ and animals’ health.Resveratrol(RSV) is a natural compound with various biological activities. The current study is aimed to evaluate the analgesic and anti-inflammatory activities of RSV in vivo. Materials and Methods. The analgesic effects were assessed by the acetic acid-induced writhing and hot plate tests. The anti-inflammatory effects were determined using the xylene-induced mouse ear oedema, the acetic acid-induced rat pleurisy, and carrageenan-induced rat synovitis tests, respectively.Results. The analgesic results showed that RSV could significantly inhibit the number of writhes and improve the time and pain threshold of mice standing on hot plate. The anti-inflammatory results showed that RSV could inhibit the ear oedema of mice. In acetic acid-induced pleurisy test, RSV could significantly inhibit the WBC and pleurisy exudates, could decrease the production of NO, and elevate the activity of SOD in serum. In carrageenan-induced synovitis test, RSV could reduce the content of MDA and elevate the T-SOD activity in serum; RSV could inhibit the expressions of TP, PGE2, NO, and MDA.Conclusion. Shortly, these results indicated that RSV had potent analgesic and anti-inflammatory activities and could be a potential new drug candidate for the treatment of inflammation and pain.

Borneol, a bicyclic monoterpene, has been evaluated for antinociceptive and anti-inflammatory activities. Antinociceptive and anti-inflammatory activities were studied by measuring nociception by acetic acid, formalin, hot plate, and grip strength tests, while inflammation was prompted by carrageenan-induced peritonitis. The rotarod test was used to evaluate motor coordination. Borneol produced a significant (P<0.01) reduction of the nociceptive behavior at the early and late phases of paw licking and reduced the writhing reflex in mice (formalin and writhing tests, resp.). When the hot plate test was conducted, borneol (in higher dose) produced an inhibition (P<0.05) of the nociceptive behavior. Such results were unlikely to be provoked by motor abnormality. Additionally, borneol-treated mice reduced the carrageenan-induced leukocytes migration to the peritoneal cavity. Together, our results suggest that borneol possess significant central and peripheral antinociceptive activity; it has also anti-inflammatory activity. In addition, borneol did not impair motor coordination.
