The studies on the biological activities of the plants used in traditional medicine shed light on the discovery and development of new active drug molecules. For centuries, in rural areas, the efficacious plants have been used in simple formulations to treat several diseases. Because of the side effects caused mostly by synthetic drugs, much attention has been recently focused on the natural compounds. In vivo and in vitro anti-inflammatory, antinociceptive, and antipyretic evaluations of medicinal plants provide scientific evidence for the ethnomedicinal features and may lead to the development of new drug candidates. This special issue, thus, aims to capture recent advances in research on anti-inflammatory, antinociceptive, and antipyretic properties of medicinal plants. We invite authors from all parts of the world to contribute original research and review manuscripts that evaluate the anti-inflammatory, antinociceptive, and antipyretic effects of medicinal plants. We are particularly interested in manuscripts that describe assessment of anti-inflammatory, antinociceptive, and antipyretic activities by in vitro and in vivo experimental models. Potential topics include, but are not limited to:

• Anti-inflammatory, antinociceptive, and antipyretic activities of plant extracts and their constituents
• In vivo and in vitro activity models on anti-inflammatory, antinociceptive, and antipyretic activities
• Biological activity-guided isolation studies
• Elucidating the mechanism of action

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/aps/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
