Anti-inflammatory and analgesic effects of ethanol and aqueous extracts of Pterocephalus hookeri (C.B. Clarke) Höeck

Aim of the study

This study evaluates the anti-inflammatory and analgesic activities of the ethanol and aqueous extracts of a Tibetan herb Pterocephalus hookeri (C.B. Clarke) Höeck to provide experimental evidence for its traditional use such as cold, flu and rheumatoid arthritis.

Materials and methods

Investigations on the analgesic effects of P. hookeri (C.B. Clarke) Höeck were carried out, including hot-plate test and acetic acid-induced writhing. The anti-inflammatory activities were observed by utilizing the following models: carrageenin-induced edema of the hind paw of rats, cotton pellet-induced granuloma formation in rats, acetic acid-induced permeability, and xylene-induced ear edema in mice. The effects of the administration of indomethacin were also studied.

Results

It has been shown that the ethanol and aqueous extracts significantly increased the hot-plate pain threshold and reduced acetic acid-induced writhing response in mice. The ethanol and aqueous extracts remarkably inhibited the increase in vascular permeability induced by acetic acid and ear edema induced by xylene. The ethanol extract also significantly decreased the carrageenin-induced rat paw edema perimeter and inhibited the increase of granuloma weight.

Conclusion

The results show that the ethanol and aqueous extracts have both central and peripheral analgesic activities and as anti-inflammatory effects, supporting the traditional application of this herb in treating various diseases associated with inflammation and pain.     

Anti-inflammatory and analgesic properties of the leaf extracts and essential oil of Lavandula angustifolia Mill

Extracts obtained from the leaves of Lavandula angustifolia Mill. (Lamiaceae) are used in Iranian folk medicine as remedies for the treatment of various inflammatory diseases. For evaluation of its probable analgesic and anti-inflammatory effects, hydroalcoholic extract, polyphenolic fraction and essential oil of the leaves of the herb were prepared and their analgesic effects were studied in mice using formalin and acetic acid-induced writhing tests. Carrageenan test in rats was used for assessment of anti-inflammatory activity of above-mentioned fractions. Results showed that while the hydroalcoholic extract (400-1600 mg/kg, p.o.) inhibited only the second phase of formalin test, the polyphenolic fraction (800 and 1600 mg/kg, p.o.) and essential oil (100 and 200 mg/kg, p.o.) suppressed both phases. In acetic acid-induced writhing test, polyphenolic fraction (400 and 800 mg/kg, p.o.) and essential oil (100 and 200 mg/kg, p.o.) reduced the number of abdominal constrictions. Essential oil at a dose of 200mg/kg also inhibited carrageenan-induced paw edema. Results of the present study confirm the traditional use of Lavandula angustifolia for the treatment of painful and inflammatory conditions and calls for further investigations to determine the active chemical constituent(s).

Anti-inflammatory and analgesic effects of Daphne retusa Hemsl

Daphne retusa Hemsl. belongs to the genus Daphne, a member of Thymelaeaceae family. The barks and stems of Daphne retusa are used as a folkloric medicine 'Zhu Shi Ma' in Western China because of its effects of detumescence and acesodyne. In this paper, we investigate the anti-inflammatory and analgesic effects of the 75% ethanol extract of the stems and barks of Daphne retusa and different fractions partitioned with petroleum ether, methylene chloride, ethyl acetate and n-butanol, respectively. The anti-inflammatory effects were evaluated using xylene-induced ear oedema in mice and carrageenan-induced paw oedema in rats, while the acetic acid-induced writhing test and hot-plate test as models for evaluating the centrally and peripherally analgesic activity. The results showed the plant has significant anti-inflammatory and analgesic effects (P<0.05-0.01). Meanwhile, the result of the acute toxicity test at which the MTD was above 5g/kg indicates that the plant extract is relatively safe in, and/or non-toxic to, mice. The findings of these experimental animal studies indicate that the Daphne retusa ethanol extract possesses anti-inflammatory and analgesic properties, and thus provide pharmacological support to folkloric, ethnomedical uses of 'Zhu shima' in the treatment and/of management of anti-inflammatory and painful conditions in China.
