"She is under observation and is responding to treatment," the sources added.
Salma was hospitalised last night when she complained of anxiety and chest pain soon after Salman was sentenced to five years' rigorous imprisonment in a black buck poaching case by a Jodhpur court.
Salma's younger son and actor Sohail Khan was at the hospital with his mother the whole night, sources said adding that her husband Salim Khan and daughter-in-law Malaika Arora Khan visited her yesterday.
