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 analgesic and anti-inflammatory properties of Zhumeria majdae essential oil were investigated in mice and rats. The analgesic activity of the oil was assessed by acetic acid-induced writhing and Eddy's hot plate methods while the acute anti-inflammatory effect was investigated by inflammatory paw edema in rat. Z. majdae oil significantly decreased the number of acetic acid-induced writhes in mice compared with animals that received vehicle only. Also it exhibited a central analgesic effect as evidenced by a significant increase in reaction time in the hot plate method. The oil also significantly reduced carrageenan induced paw edema in rats. The inhibitory activity of Z. majdae essential oil was found to be very close to that of the standard drug, diclofenac sodium (50 mg/kg). The studied oil was analyzed by GC and GC–MS and seventeen constituents were identified, representing 99.2% of the oil. The major components of the oil were characterized as linalool (63.4%) and camphor (27.5%), which might be responsible for these observed activities. The results suggest that Z. majdae essential oil possesses biologically active constituent(s) that have significant activity against acute inflammation and have central and peripheral antinociceptive effects which support the ethnomedicinal claims of the plant application in the management of pain and inflammation.

AbstractThis study evaluate the anti-inflammatory and analgesic properties ofHelianthus annuusLinn. in rats. Methanol extract ofHelianthus annuus(HAE) leaf was used in this study. Formalin- and egg-albumin induced-paw edema were used to investigate the anti-inflammatory activities while acetic acid-induced writhing reflex and tail flick models were used to evaluate the analgesic properties. The doses of HAE used were 150, 300 and 600 mg/kg. Acetylsalicylic acid (ASA) was used as reference drug in the anti-inflammatory and writhing reflex models while pentazocine (reference drug) was used in tail flick model. The negative control was dosed 5% tween-20 (10 ml/kg). The HAE exhibited significant (P < 0.05) dose-dependent anti-inflammatory and analgesic activities. At 3 hour (h) post treatment, the HAE (300 mg/kg) produced 33.33% and 32.94% while ASA produced 36.36% and 35.29% reduction in paw volume in the formalin and egg-albumin induced paw edema models respectively when compared with negative control. In the acetic acid-induced writhing reflex, ASA and HAE (600 mg/kg) produced 67.89% and 35.78% reduction in the number of writhing, respectively when compared with the negative control. Pentazocine and HAE (300 mg/kg) caused 67.62% and 35.24% increase in pain reaction time when compared with the negative control. The study affirms the folkloric uses ofHelianthus annuusin the management of pain and inflammation.

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.

Uapaca togoensis Pax. (Euphorbiaceae) is used in traditional medicine to treat several diseases including pain, inflammation and fever. This study investigated analgesic, anti-inflammatory and anti-pyretic effects of the residual aqueous fraction of the plant. Preliminary phytochemical screening and acute toxicity studies were conducted. Analgesic activity was evaluated using acetic acid-induced writhing, hot plate and formalin-induced pain tests at doses of 250, 500 and 1000 mg/kg, p.o. Anti-inflammatory and antipyretic activities were investigated using carrageenaninduced paw edema and Brewer’s yeast-induced pyrexia model respectively in rats. Oral median lethal dose of the fraction was found to be greater than 5000 mg/kg. The fraction significantly (p<0.05) reduced the number of acetic acid-induced writhes and increased the reaction time of mice to thermal stimuli. In the formalin test, a significant (p<0.05) reduction in mean pain score was observed at the second phase. A significant (p<0.05) decrease in paw edema at the 4th and 5th hours and a reduction in temperature was also observed at the 22nd hour. Phytochemical screening revealed the presence of saponins, tannins, steroids, cardiac glycosides, flavonoids, alkaloids and triterpenes. The result of the study revealed that the fraction possesses analgesic, anti-inflammatory and antipyretic activities, validating the folkloric use of the plant.

Introduction: Bubonium graveolens is used in traditional pharmacopoeia against imbalances of the gastrointestinal tract, cephalic pains, and bronchitis, and as an anti-inflammatory agent. Methods: We have investigated the analgesic and anti-inflammatory activities of the aqueous extract of Bubonium graveolens in male mice of strain NMRI Albinos, weighing between 22 g and 38 g. Acetic acid was used to induce writhes in the mice and inflammation of paw edema. Results: Evaluation of the analgesic activity showed that the aqueous extract at 150 mg/kg of the plant induced a decrease in the number of abdominal cramps caused by 1% acetic acid. The aqueous extract of the plant had an analgesic effect almost equal to that of Diclofenac; in fact, the latter caused a pain inhibition of 49 ± 1.1% while Bubonium graveolens caused a pain inhibition of 49.6 ± 2.1%, at the concentration of 150 mg/kg. Evaluation of the percentage of inhibition showed that the aqueous extract of Bubonium graveolens had a better anti-inflammatory activity compared to Diclofenac sodium during the treatment duration (69.57% — 56.52% at 60 min; 71.43% — 50.00% at 120 min, and 75.00% — 66.67% at 180 min). Conclusion: The results of this research indicate that Bubonium graveolens inhibits inflammation and could explain its effective use in traditional medicine.

Malaria is an endemic disease globally and the conundrum of drug resistance has led to the search for newer antimalarial agents. The root extract ofH. barteriwas evaluated for antimalarial, analgesic, and anti-inflammatory properties. The prophylactic effect ofH. barterionP. bergheiwas determined by pretreating mice with aqueous root extract ofH. barteri(30–300 mg/kg), saline, and 1.2 mg/kg sulfadoxine/pyrimethamine for three days followed by 1 × 106P. bergheiinoculation. Parasite density was measured after 72 h. The curative antimalarial property of the extract was assessed by treating mice with extract, saline, and 1.14 : 6.9 mg/kg Artemether : Lumefantrine four days after 1 × 106P. bergheiinoculation. Selected organs were harvested for toxicity assessment. The anti-inflammatory and analgesic effect of the extract was determined in the carrageenan and thermal tail withdrawal tests, respectively. The extract significantly reduced the parasite density in the prophylactic but not the curative study. The anti-inflammatory and analgesic activities of the extract were significant (P<0.05) only at the highest doses employed. Regeneration of hepatocytes was also evident in the extract treated groups. The extract has prophylactic but not curative activity onP. berghei-induced malaria. The anti-inflammatory and analgesic property of the extract occurred at the highest doses used.

Abstract PCA (protocatechuic acid), a phenolic compound found in teas, fruits and vegetables, is widely recognized with its antioxidant and anti-inflammatory activities. Here we verified the protective role of PCA on carrageenan-induced paw edema in mice. PCA (25 mg/kg and 50 mg/kg) administration was applied for five consecutive days prior to the carrageenan injection. Diclofenac sodium (20 mg/kg) was used as a reference drug. PCA pretreatment notably decreased the volume of the developed edema and alleviated the histopathological alterations induced by carrageenan. Additionally, PCA administration enhanced the cellular antioxidant capacity as demonstrated by the increased levels of catalase, superoxide dismutase and reduced glutathione, in addition to the decreased malondialdehyde level in the edematous tissue. Interestingly, PCA administration was able to suppress the developed inflammatory response upon carrageenan injection as indicated by the decreased levels and expression of pro-inflammatory cytokines and mediators including tumor necrosis factor alpha, interlukin-1 beta, interlukin-6, inducible nitric oxide synthase, nitric oxide, cyclooxygenase-II, prostaglandin E2, monocyte chemoattractant protein-1, myeloperoxidase and nuclear factor kappa B. These results collectively confirm the protective effect of PCA against carrageenan-induced paw edema owing to its antioxidant and anti-inflammatory characteristics.

The ostrich oil of Struthio camelus (Ratite) found uses in folk medicine as an anti-inflammatory in eczema and contact dermatitis. The anti-inflammatory effect of a γ-lactone (5-hexyl-3H-furan-2-one) isolated from ostrich oil and its formulated nano-emulsion in formalin-induced paw edema was investigated in this study. Ostrich oil was saponified using a standard procedure; the aqueous residue was fractionated, purified, and characterized as γ-lactone (5-hexyl-3H-furan-2-one) through the interpretation of IR, NMR, and MS analyses. The γ-lactone was formulated as nano-emulsion using methylcellulose (MC) for oral solubilized form. The γ-lactone methylcellulose nanoparticles (γ-lactone-MC-NPs) were characterized for their size, shape, and encapsulation efficiency with a uniform size of 300 nm and 59.9% drug content. The γ-lactone was applied topically, while the formulated nanoparticles (NPs) were administered orally to rats. A non-steroidal anti-inflammatory drug (diclofenac gel) was used as a reference drug for topical use and ibuprofen suspension for oral administration. Edema was measured using the plethysmograph method. Both γ-lactone and γ-lactone-MC-NPs showed reduction of formalin-induced paw edema in rats and proved to be better than the reference drugs; diclofenac gel and ibuprofen emulsion. Histological examination of the skin tissue revealed increased skin thickness with subepidermal edema and mixed inflammatory cellular infiltration, which were significantly reduced by the γ-lactone compared to the positive control (p-value = 0.00013). Diuretic and toxicity studies of oral γ-lactone-MC-NPs were performed. No diuretic activity was observed. However, lethargy, drowsiness, and refusal to feeding observed may limit its oral administration.

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.
