RESEARCH QUALITY ASSESSMENT:
- The studies reviewed are systematic reviews and meta-analyses, which provide comprehensive analyses of existing research and are considered high-quality evidence.
- Variability in Echinacea preparations and study methodologies contributes to inconsistent findings, highlighting the need for standardized research protocols.
- While short-term use of Echinacea appears safe, potential drug interactions necessitate caution, especially for individuals on prescription medications.
- Further research with standardized Echinacea preparations and methodologies is needed to conclusively determine its efficacy and safety.
