We studied the dark matter induced Mikheyev-Smirnov-Wolfenstein effect on neutrino
oscillations in the Sun. However, to have sizable effect, we found that the dark matter cannot self-annihilate, for instance, the asymmetric dark matter. From the solar neutrino data, we found strong constraint on the interaction between dark matter and neutrino for asymmetric dark matter with mass less than 40 GeV.
