What the texts say
Sushruta says these pairs become like poison. Salt sits in his list with sour fruits, horse gram, curd and oil, and his word for it is simply lavana, salt. Vagbhata's Ashtanga Sangraha also names salt with milk.[1][2]
The modern view
We have not found a modern study that tests salt eaten with milk. The comparison to poison is the text's own, not a finding from any study.
From the classical texts
Questions people ask
Is rock salt (sendha namak) different?
Sushruta's word is lavana, salt, and the texts we opened make no exception for rock salt.[1]
