The relaxation rate ..nu../sub p/ of poloidal rotation in the banana regime in tokamaks is calculated using a time-dependent parallel viscosity. It is found that ..nu../sub p/ is on the order of ..nu../sub i//sub i/, the ion--ion collision frequency, with no geometric enhancement factor associated with toroidicity.
