Safety and Intake Effect of EPs® 7630 (an Extract of the Roots of Pelargonium Sidoides)

Safety and Intake Effect of EPs® 7630 (an Extract of the Roots of Pelargonium Sidoides) A Prospective, Monocentric, Randomised, Double-blind, Placebo-controlled Clinical Trial

The aim of the study is to evaluate the safety of the intake of EPs® 7630 during a long-term (4 months) medication. The protective effects of EPs®7630 and its effects during a cold episode will also be studied.

Study Overview

• Status: Completed
• Conditions: Common Cold
• Intervention / Treatment: Drug: EPs® 7630; Drug: Placebo

Detailed Description

The main objective of this clinical trial is to evaluate the safety of EPs® 7630 intake - used as continuous protection and at the onset of cold symptoms - in adult participants during a long-term (4 months) medication. Due to the sparseness of empirical data in the population and this setting, no confirmatory hypotheses are formulated and the data will be analysed descriptively.
