Antiinflammatory and antinociceptive activities of Blechnum occidentale L. extract

Abstract

The results described here are the first report of pharmacological studies of Blechnum occidentale L. and indicate that this plant has antinociceptive and antiinflammatory activities which support its folk medicine use.

Biosynthesis, characterization, and evaluation of bioactivities of leaf extract-mediated biocompatible silver nanoparticles from an early tracheophyte,<em> Pteris tripartita</em> Sw.

“…58,97 Other ferns, including Equisetum arvense, Cyathea phalerata, and Blechnum occidentale, have also been shown to display anti-inflammatory and antioxidant activity due to the presence of secondary metabolites like phenolic compounds. 98,99 Over the duration of this study, no deaths occurred in any of the experimental groups. Moreover, the extracts did not induce morphological variations or any toxic signs in the animal subjects.…”

Anti-inflammatory, analgesic, and antioxidant activities ofPisonia aculeata: Folk medicinal use to scientific approach

“…Pain induced by formalin test represents two distinct phase, early phase of formalin test represents centrally mediated pain, while the late phase pain indicates pain mediated by a peripheral effect via release of transmitters such as histamine, serotonin, prostaglandins, kinins, etc. (Nonato et al, 2009). Results indicated that the extract produced better activity in second phase, therefore analgesic effects of the extract might be mediated through a peripheral mechanism rather than a central mechanism.…”

A review of the use of pteridophytes for treating human ailments

“…(Otsuka et al, 1972), Cheilanthes farinosa (Yonathan et al, 2006), Cyathea gigantea (Fig. 3c) (Benjamin and Manickam, 2007;Madhukiran and Ganga Rao, 2011), Blechnum occidentale (Nonato et al, 2009), D. mariesii (Chang et al, 2007b), Microsorum scolopendria (Bloomfield, 2002), Phyllitis scolopendrium (Bonet and Valles, 2007), and P. leucotomos (Lucca, 1992). In addition, wound healing activity has been reported for many species of ferns such as D. solida (Whistler, 1992), Polystichum pungens (Grierson and Afolayan, 1999), A. evecta (Cambie and Ash, 1994), Nephrolepis cordifolia (Fig.…”
