| echinacea tennesseensis ethanol tinctures harbor cytokine- and proliferation-enhancing capacities. | members of the genus echinacea are used medicinally to treat upper respiratory infections such as colds and influenza. the aim of the present investigation was to characterize the phytomedicinal properties of the american federally endangered species echinacea tennesseensis. | 2009 | 19286391 |
| human blood mononuclear cell in vitro cytokine response before and after two different strenuous exercise bouts in the presence of bloodroot and echinacea extracts. | the purpose of this multidisciplinary investigation was to characterize cytokine production by human blood mononuclear cells after 2 contrasting exercise bouts (a maximal graded oxygen consumption [vo(2)max] test and 90 min of cycling at 85% of ventilatory threshold [vt]) when stimulated in vitro with extracts from bloodroot (sanguinaria canadensis), coneflower (echinacea tennesseensis), or solvent vehicle controls. blood was sampled pre- and post-exercise. production of tnf, il-1beta, and il-10 ... | 2009 | 19766513 |
| endogenous levels of echinacea alkylamides and ketones are important contributors to the inhibition of prostaglandin e2 and nitric oxide production in cultured macrophages. | because of the popularity of echinacea as a dietary supplement, researchers have been actively investigating which echinacea constituent or groups of constituents are necessary for immune-modulating bioactivities. our prior studies indicate that alkylamides may play an important role in the inhibition of prostaglandin e2 (pge(2)) production. high-performance liquid chromatography fractionation, employed to elucidate interacting anti-inflammatory constituents from ethanol extracts of echinacea pu ... | 2009 | 19807154 |
