Brainwave measurement
It can be said that “igusa” has a calming effect as it promotes an increase in alpha band amplitude of occipital brain waves, which tends to occur during a relaxed state.
The presence of “igusa” enhances the amplitude of brainwave alpha frequencies, inducing a state of relaxation.
