What the texts say
Charaka calls this parihara viruddha, an incompatibility in what is taken afterwards. The word is uṣṇa, "hot", so the rule covers hot food as well as hot drinks. It names pork (varāha) "and the like". The same line has a mirror rule: cold things after drinking ghee.[1]
The modern view
We found no study that tests this rule.
