this experiment was conducted to evaluate the efficacy of different levels of echinacea (echinacea purpurea) methanol extract on the growth performances (final weight (fw), daily growth ratio (dgr), feed conversion rate (fcr), voluntary feed intake (vfi) and protein efficiency ratio (per) and some of hematological parameters (hemoglobin (hb), hematocrit (hct), red blood cell (rbc) and white blo...

Due to the limited availability of effective pharmaceutical products and serious side effects of the available therapy for leishmaniasis, search for useful medicinal plants is necessary. Previous studies reported preventative effect of Echinacea against Leishmania infections through immunologic stimulation. Here we tested concentrated ethanolic extract of the root of Echinacea purpurea prepared...

BACKGROUND Echinacea preparations are widely used to treat the common cold. OBJECTIVE To assess the efficacy of dried, encapsulated, whole-plant echinacea as early treatment for the common cold. DESIGN Randomized, double-blind, placebo-controlled community-based trial. SETTING University of Wisconsin-Madison, Madison, Wisconsin. PARTICIPANTS 148 registered students with common colds of ...

The headspace volatile components of roots, stems, leaves, and flowers of Echinacea angustifolia,E. pallida, and E. purpurea were analyzed by capillary gas chromatography/mass spectrometry (GC/MS). Over 70 compounds were identified in the samples. All plant tissues, irrespective of the species, contain acetaldehyde, dimethyl sulfide, camphene, hexanal, beta-pinene, and limonene. The main headsp...

Ongoing studies have developed strategies for identifying key bioactive compounds and chemical profiles in Echinacea with the goal of improving its human health benefits. Antiviral and antiinflammatory-antipain assays have targeted various classes of chemicals responsible for these activities. Analysis of polar fractions of E. purpurea extracts showed the presence of antiviral activity, with ev...

The present investigation evaluated the efficacy of a botanical supplement that delivered a concentrated dose of Echinacea purpurea (8 grams day(-1)). The participants were 13 apparently healthy, recreationally active college students (VO2 max: 51 mL O2/kg∗min). The participants were provided with a 30-day supplementation regime. Data regarding maximum aerobic capacity was collected through pre...
