Celastrus paniculatus Willd. (Celastraceae), commonly known as Staff tree in English, is a woody climber grown in tropics and subtropics and also cultivated commercially in India for the high demand of its seed oil. The present study assessed the different solvent extracts of C. paniculatus leaf for the evaluation of their analgesic potential by acetic acid induced writhing assay in Swiss albin...

INTRODUCTION Pain is a very well-known signal of ill health and analgesics are the drugs that are used to relieve pain. The main problem with these drugs remains that of side effects. Safer alternatives are natural herbs. Guduchi (Tinospora cordifolia) is one such plant with analgesic potential but few studies are there. OBJECTIVE To evaluate the analgesic activity of commercially available e...

We have investigated the antinociceptive effects of the essential oil of Ocimum gratissimum L. (Labiatae) (EOOG) in two classical models of pain in male Swiss mice (25-35 g), the writhing test and the formalin test. At doses of 30, 100 and 300 mg/kg (po), EOOG produced a dose-dependent inhibition (from 58.3 4.4 to 40.7 6.3, 36.4 3.6 and 24.6 3.6, respectively; N = 8-10, P<0.05) of aceti...

BACKGROUND Gmelina arborea Roxb (Verbenaceae), also known as "Gambhari", is an important medicinal plant in the Ayurveda. There are no meticulous scientific reports on effect of the plant on inflammation and pain. OBJECTIVE To study the anti-inflammatory and anti-nociceptive properties of aqueous extracts (AE) and methanol extracts (ME) of G. arborea. MATERIALS AND METHODS The AE and ME of ...

In the present study, the antinociceptive profiles of hop extract were characterized in ICR mice. Hop extract administered orally (from 25 to 100 mg/kg) showed an antinociceptive effect in a dose-dependent manner as measured in the acetic acid-induced writhing test. Antinociceptive action of hop extract was maintained at least for 60 min. Moreover, cumulative response time of nociceptive behavi...

BACKGROUND Vanda tessellata (Orchidaceae) has been used in different sorts of ailments such as inflammations, rheumatism, dysentery, bronchitis, dyspepsia and fever in folk medicine. In this study we evaluated the antinociceptive and cytotoxic effect of methanol and aqueous extracts of V. tessellata leaf. METHODS Oral administration of V. tessellata aqueous (VTA) and methanol (VTM) leaf extra...

In the present study, we investigated the role of 5-hydroxytryptamine type 3 (5-HT(3)) receptors in hypnosis and analgesia induced by emulsified sevoflurane. A mouse model of hypnosis and analgesia was established by an intraperitoneal or subcutaneous injection of emulsified sevoflurane.We intracerebroventricularly (i.c.v.) or intrathecally (i.t.) administered YM-31636, a 5-HT(3) receptor agoni...

Geodorum densiflorum, Diospyros blancoi, Baccaurea ramiflora and Trichosanthes dioica are four important medicinal plants used traditionally in various diseases. Different parts of these plants have been used in different painful conditions. Therefore, the present study was designed to investigate the analgesic activities of methanol extract of pseudobulb of G. densiflorum, seeds of D. blancoi,...

Phytochemical screening was carried out on the ethylacetate portion of the ethanolic extract of the leaves of Pseudocedrella kotschyii and then evaluated for its analgesic (acetic acid-induced writhing) and anti-inflammatory (raw egg albumin-induced oedema) activities in mice and rats respectively. Phytochemical screening of the ethylacetate partition portion of ethanolic extract revealed the p...

This paper describes the isolation, identification and analgesic activity of a new biflavonoid from Rheedia gardneriana leaves, which correspond to I3-naringenin-II8-4'-OMe-eriodictyol (GB-2a-II-4'-OMe) (1), with a methoxyl group in position 4 of ring-II. Its structure was determined by spectroscopic data and confirmed by an alkaline hydrolysis. Its analgesic effect was evaluated in a writhing ...
