Common cold

Clinical trial, with positive findings,  on 115 German army soldiers suffering from common cold. Approximately  half of the soldiers were randomly allocated to receive a homeopathic  medicine called Gripp-Heel and the others received Aspirin; they were  not told which treatment group they were in. On the 4th and 10th days of  treatment, there was no difference in symptom improvement between the  two treatment groups, showing that Gripp-Heel and Aspirin were similarly  effective.
