A prospective randomized study compared the success rate to a comparative examination in medical sciences of 26 students who were given Hericium erinaceus (HE) and followed a Tomatis® program versus 42 control students. The group Tomatis/HE was first composed with 42 studients. However, 16 persons (including 11 doublings) did not perform any training or take any HE. The success rate was equal to 69.2% in the HE/Tomatis® group versus 51,2% in the control group (P < 0.05). The success rate in the HE/Tomatis® group was equal to 66.7% in students who tried for the first time versus 25% in the control group (P < 0.001). For the sub-group Tomatis®/HE of 16 non-observers, the success rate was similar to the control group (50 versus 51.2%) except for doubling (54.5 versus 88.2%; P < 0.001) suggesting some lack of motivation. HE/Tomatis® increases the success rate in comparative medical examinations for motivated students.
