In this Comment we deal with a recent study of Ying Wu et al. Phys. Rev. A 67, 013811 2003 on a four-wave mixing process. We show that the authors’ claim, that a large enhancement of the generation efﬁciency can be obtained by suppression of photon absorption from electromagnetically induced transparency, is not correct.
