Abstract: The effectiveness of the prophylactic intake of a combined echinacea preparation regarding the number of flu cases was tested in a placebocontrolled, double-blind study in 646 students during the winter period 1989/ 90. The fluid preparation was taken daily. The time of treatment was 8 weeks. 609 subjects (303 verum and 306 placebo cases) finished the study. In the entire verum group there were 15% less primary infections and 27% less cases of recidivation compared to the placebo group. In 363 students with increased numbers of infections prior to the study, the difference in infect frequency between verum and placebo was nearly 20%. Thus, the treatment with the verum prohibited in the entire group each 7th primary infection case and each 4th case of recidivation and in the subgroup of subjects with increased infection frequency each 5th infection was prevented.
