Evaluating The Safety And Clinical Efficacy Of Elderberry Extract In Patients With Influenza
Evaluating The Safety And Clinical Efficacy Of Elderberry Extract In Patients With Influenza
This research is being done to determine if an extract of cooked elderberries will help
 decrease the duration and severity of influenza symptoms in patients with confirmed
 influenza. Involvement in this study requires an initial patient screening at the time of
 their Emergency Department visit in order to confirm eligibility for the study. Once patients
 have been consented and enrolled as a participant, they will be randomized to take by mouth
 either Elderberry Extract or a placebo (a similar appearing and tasting liquid without
 elderberry) for a duration of 5 days. Study information regarding medication adherence, body
 temperature, symptoms, severity of symptoms, and any possible side effects will be collected
 from daily phone surveys conducted by the study coordinator. Participation in the study will
 end after at least 5 days once the patient has not had a temperature above 100°F and has had
 no influenza symptoms for at least 24 hours, or after 21 days in the study, whichever occurs
 first.
