The purpose of this investigation was to determine whether echinacea supplementation results in alterations of erythroid growth factors and erythropoietic status. Twenty-four men age 24.9 +/- 4.2 y, height 1.7 +/- 0.8 m, weight 87.9 +/- 14.6 kg, and 19.3% +/- 6.5% body fat were grouped using a double-blind design and self- administered an 8000-mg/d dose of either echinacea (ECH) or placebo (PLA) in 5 x 400 mg x 4 times/d for 28 d. Blood samples were collected and analyzed for red blood cells…

Six weeks of oral Echinacea purpurea supplementation does not enhance the production of serum erythropoietin or erythropoietic status in recreationally active males with above-average aerobic fitness.
TLDR
It is indicated that 6 weeks of oral E. purpurea supplementation in recreationally active males with above average aerobic fitness did not enhance EPO or erythropoietic status, and these findings are in contrast with previous reports of E. Purpurea supplements in untrained participants with average fitness levels, but consistent with observations in trained endurance athletes.
Running Economy and Maximal Oxygen Consumption After 4 Weeks of Oral Echinacea Supplementation
TLDR
The data suggest that ECH supplementation results in significant increases in EPO, V[Combining Dot Above]O2max, and running economy, which is consistent with previous studies of Echinacea supplementation.
EFFECT OF ECHINACEA EXTRACT SUPPLEMENTATION ON GROWTH PERFORMANCE AND HEMO-BIOCHEMICAL TRAITS OF GROWING RABBITS
TLDR
The results indicate that treatment of growing rabbits with Echinacea extract in different doses improved growth performance, stimulates immune functions and protein metabolism without harmful effects on liver and kidney functions.
Echinacea-Based Dietary Supplement Does Not Increase Maximal Aerobic Capacity in Endurance-Trained Men and Women
TLDR
This echinacea-based dietary supplement provided at two different doses would increase erythropoietin (EPO) and other blood markers involved in improving aerobic capacity and maximal oxygen consumption (VO2max) in endurance-trained men and women should not be recommended as a means to improve performance in endurance athletes.
Rabbit dietary supplementation with pale purple coneflower. 1. Effects on the reproductive performance and immune parameters of does.
TLDR
No impacts of EPAL have been observed on the reproductive or haematological parameters of the does, and the effects of dietary supplementation with EPAL on the performances, bacterial community, blood parameters and immunity in growing rabbits are reported.
The Use of Echinacea to Improve Oxygen Transport Capacity
TLDR
An increase in oxygen transport capacity with Echinacea supplementation may provide a therapeutic means by which to diminish the adverse effects caused by a decrease in oxygen availability and enhance endurance exercise performance through the same mechanism.
Echinacea supplementation: does it really improve aerobic fitness?
TLDR
The published literature does not support the use of Echinacea as an ergogenic aid to improve aerobic fitness in healthy untrained or trained subjects.

Immunological and haematinic consequences of feeding a standardised Echinacea (Echinacea angustifolia) extract to healthy horses.
TLDR
It was concluded that Echinacea effectively stimulates equine immunocompetence, and the plant extract behaves, in equine subjects, as a haematinic agent, i.e. one which improves the quality of blood by increasing haemoglobin levels and the number of erythrocytes and which is considered to improve parameters of exercise physiology and performance.

Effect of enhanced erythropoiesis on iron absorption.
TLDR
It is concluded that the striking enhancement of iron absorption following regular erythropoietin administration in normal subjects is related to the combined effect of diminished iron stores and augmented eryththropoiesis.

TLDR
The mechanism for the control of kidney production of erythropoietin is not well understood but is postulated to be regulated by the oxygen level in a critical renal sensor cell, and has been the subject of several investigations and reviews.

TLDR
It has been postulated that Epo decreases the rate which Epo-dependent progenitor cells undergo programed cell death (apoptosis), and there are two major signal transduction pathways activated by the Epo receptor: the JAK2-STAT5 pathway and the ras pathway.

Immunopharmacological activity of Echinacea preparations following simulated digestion on murine macrophages and human peripheral blood mononuclear cells
TLDR
Echinacea herb and root powders were found to stimulate murine macrophage cytokine secretion as well as to significantly enhance the viability and/or proliferation of human PBMCs in vitro.
Erythropoietin, iron, and erythropoiesis.
TLDR
Newer measurements of erythrocyte and reticulocyte indices using automated counters show promise in the evaluation of iron-restricted erythropoiesis, suggesting traditional biochemical markers of storage iron in patients with anemia caused by chronic disease are unhelpful in the assessment of iron status.
