Echinacea research - what is the evidence supporting the Commission E monographs claim that the herb Echinacea should be discontinued after 8 weeks of use
Abstract
The aim of this piece of research is not to review the efficacy of Echinacea, but to review the literature available and decide if there is currently any supporting evidence for the Commission E monographs claim that Echinacea should be discontinued after 8 weeks.
The claim is supported by a repetitive theme from herbal laypersons and manufacturers of over the counter Echinacea products, that the course of treatment of Echinacea should be broken after a certain amount of days. This period can vary greatly, from person to person and company to company.
Review and analysis of previous research in the area.
There has been a great deal of research carried out on Echinacea species. Currently there appears to be over 350 scientific studies available looking at different aspects of Echinacea. I have reviewed a number of trials selecting the most relevant ones with regard to duration of administration of Echinacea.
