Swiss Echinacea Extract Shown Safe and Effective in Preventing Colds in Largest Echinacea Clinical Trial

摘要

Colds and flu, associated with a variety of viral infections, are characterized by symptoms such as sore throat, cough, and nose irritations, as well as systemic complaints such as headache, malaise, and fever. The common cold alone causes great discomfort and is a major reason for school and work absences, as well as physicians visits. Preventative strategies have included antiviral agents or vaccines targeted towards infection prevention or inhibition of viral replication; however, common problemsarise with adverse side effects (ASE) and/or the failure to protect certain populations.
